Description:
BACKGROUND OF INVENTION 
     Field of Invention 
     The present invention is directed to new and improved methods of and apparatus for producing libraries of sampled and/or synthesized virtual musical instruments that can be used to produce automated digital performances of music compositions having greater degree of uniqueness, expressiveness and realism, in diverse end-user applications. 
     Brief Description of the State of Art 
     Applicant&#39;s mission is to enable anyone to express themselves creatively through music regardless of their background, expertise, or access to resources. With this goal in mind, Applicant has been inventing and building tools powered by innovative technology designed to help people create and customize original music. As part of this process, Applicant has been bringing human know-how to automated music composition, performance, and production technology. This has involved creating sound sample libraries and datasets, for use in automatically composing, performing and producing high quality music through the fusion of advanced music theory and technological innovation. To date, Applicant&#39;s commercial AI-based music composition and production system, marketed under the brand name AMPER SCORE™, supports over one million individual samples and thousands of unique virtual musical instruments capable of producing a countless number of unique audio sounds to express and amplify human creative expression. Recorded by hand, every audio sound sample in Applicant&#39;s virtual musical instrument (VMI) sound sample libraries is sculpted with meticulous attention to detail and quality. 
     In view of the above, Applicant seeks to significantly improve upon and advance the art and technology of sampling sounds from diverse sources including (i) real musical instruments, (ii) natural sound sources found in nature, as well as (iii) artificial audio sources created by synthesis methods of one kind or another. Applicant also seeks to improve upon and advance the art of constructing and operating virtual musical instrument (VMI) libraries maintaining deeply audio-sampled and/or sound-synthesized virtual musical instruments that are designed for providing the notes and sounds required to perform virtual musical instruments and produce a digital performance of a music composition. 
     To appreciate the problems addressed and effectively solved by Applicant&#39;s inventions disclosed herein, it will be helpful to provide a brief overview on the art of sound sampling, and the surrounding music technology conventions that have supported this field and advanced music performance and production to its current state of the art, using virtual musical instrument libraries developed today around the world. At the same time, this overview will help set the stage for understanding why the same conventional music technology that has helped the industry reach its current state, also now hinders the industry in meeting the challenges of the present, moving into the future, and realizing the benefits this creative technology promises to bring to humanity. 
     Sound sampling (also known simply as “sampling”) is the process of recording small bits of audio sound for immediate playback via some form of a trigger. Historically, the sampling process has been around since the early days of Musique Concrete (in the 1940s) and came to commercial success with the invention of the Mellotron (1963). There are two main approaches to sampling, instrument sampling and loop sampling. Loop sampling is the art of recording slices of audio from pre-recorded music, such as a drum loop or other short audio samples (historically from vinyl). Amper Music uses the instrument sampling methodology in its SCORE™ AI Music Composition and Generation System. The instrument sampling process is to record and audio capture single note performances to replicate an instrument with any combination of notes. 
     In the early days (1960s-2000ish), the process of sampling was largely unchanged until the invention of computerized digital reproduction that enabled larger and deeper sampling methodologies, supporting highly complex sample instrument libraries in which each instrument is performed and recorded across its range of playable notes. As random-access memory (RAM) and hard drive storage sizes increased, libraries became more complex, and performance of these samples became extremely difficult to both perform and program via MIDI. Some companies developed solutions to help mitigate the time it takes to select these samples in real time. 
     Samplers differ from synthesizers in that the fundamental method of sound production begins with a sound sample or audio recording of an acoustic sound or instrument, electronic sound or instrument, ambient field recording, or virtually any other acoustical event. Each sample is typically realized as a separate sound file created in a suitable data file format, which is accessed and read when called during a performance. Typically, samples are triggered by some sort of MIDI input such as a note on a keyboard, an event produced by a MIDI-controlled instrument, or note generated by a computer software program running on a digital audio workstation. 
     In prior art sound sampling instruments, each sample is contained in a separate data file maintained in a sample library supported in a computer-based system. Most prior art sample libraries have several samples for the same note or event to create a more realistic sense of variation or humanization. Each time a note is triggered, the samples may cycle through the series before repeating or be played randomly. 
     Typically, the audio samples in a sample library system are organized and managed using relational database management technology (RDBMS). Modern sampling instruments require many Terrabytes of digital data storage for library data storage management capabilities, and large amounts of RAM for program memory support. In a prior art computer-based sound sample library system, the audio samples are typically stored in a zone (or other addressable region of memory) which is an indexed location in the sample library system, where a single sample is loaded and stored. In a sample library system, an audio sample can be mapped across a range of notes on a keyboard or other musical reference system. In general, there will be a Root key associated with each sample which, if triggered, will playback the sample at the same speed and pitch at which it was recorded. Playing other keys in the mapped range of a particular zone, will either speed up or slow down the sample, resulting in a change in pitch associated with the key. 
     Depending on the sample library system, zones may occupy just one or many keys, a could contain separate sample for each pitch. Some samplers allow the pitch or time/speed components to be maintained independent for a specific zone. For instance, if the sample has a rhythmic component that is synced to tempo, rhythmic part of the sound can be maintained fixed while playing other keys for pitch changes. Likewise, pitch can be fixed in certain circumstances. 
     In most conventional sound sample libraries, there will be an envelope section to control amplitude attack, decay, sustain and release (ADSR) parameters. This envelope may also be linked to other controls simultaneously such as, for example, the cutoff frequency of a low-pass filter used in sound production. 
     Typically, sound samples are either (i) One Shots, which play just once regardless of how long a key trigger is sustained, or (ii) Loops which can have several different loop settings, such as Forward, Backward, Bi-Directional, and Number of Repeats (where loops can be set to repeat as long as a note is sustained or for a specified number of times). 
     The effect of the Release stage on Loop playback can be to continue the repeat during the release or may cause a jump to a release portion of the sample. In more complex sampler instruments, there are often Release Samples specific to the type of sound and usually intended to create a better sense of realism. Like any synthesizer, most samplers will have controls for pitch bend range, polyphony, transposition and MIDI settings. 
     The energy spectrum as well as the amplitude of the sounds produced by sampled musical instruments will depend on the speed at which a piano key is hit, or the loudness of a horn note or a cymbal hit. Developers of virtual musical instrument libraries consider such factors and record each note at a variety of dynamics from pianissimo to fortissimo. These audio samples are then mapped to zones which are then be triggered by a certain range of MIDI note velocities. Some prior art sampling engines such as Kontakt from Native Instruments, allow for crossfading between velocity layers to make transitions smoother and less noticeable. 
     Grouping zones with common attributes expands the functionality of prior art sampling instruments. A common application of zone grouping is string articulations because there are numerous ways to play a note on a violin, for example: Legato bowing, spiccato, pizzicato, up/down bowing, sul tasto, sul ponticello, or as a harmonic. In advanced prior art string libraries, zone groupings based on articulations have been superimposed over the same range on the keyboard. Also, a Key Trigger or a MIDI controller have been used to activate a certain group of samples. 
     Most prior art samplers have on-board effects processing such as filtering, EQ, dynamic processing, saturation and spatialization. This makes it possible to drastically change the sonic result and/or customize existing presets to meet the needs of a given application. Prior art sound sampling instruments have employed many of the same methods of modulation found in most synthesizers for the purpose of affecting parameters. These methods have included low frequency oscillators (LFOs) and envelopes. Also, signal processing methods and paths, automation, complex sequencing engines, etc. have been developed and deployed within prior art sampling instruments as well. 
     Beyond the prior art sampling instruments described above, there is a great volume of prior art technology relating to the field of sampled virtual musical instrument design.

     Primary Problems Addressed by the Present Invention 
     Other than the MIDI Standard set in 1983, there are no real standards governing the instrument sampling industry, other than the assignment of MIDI Note Numbers to notes having a Note Name and a particular Pitch Frequency based on 12-EDO tuning, as illustrated in  FIGS. 1A through 1E . 
     The decisions of where to split a velocity of a musical instrument being sampled, how deeply should a musical instrument be sampled (e.g. how many round robins, how many microphones, how many velocities, which notes, etc.), and which MIDI data controls should be sent to select samples, have been choices left up to the sample-based musical instrument designer. While this provides an “art” to instrument sample design, it does not help when you need to know exactly how an instrument will perform and predict what it should do. This has provided “camps” of composers who prefer some approaches of sampled instruments (usually dictated by the company/person making the samples). 
     The MIDI data communications protocol was originally designed for hardware/physical instruments. MIDI is largely used/designed for musical devices to playback music in real-time. Because MIDI was a convention when software technology came into play, sending out data messages to outboard gear from the computer adapted the MIDI standard. Now that the music industry is largely software driven in most applications (and entirely software driven in others), the types of devices communicating are now much more sophisticated. Using MIDI, the industry is stuck in a 36 year-old technology. 
     MIDI&#39;s 127 data control point resolution is extremely limited. Much greater resolution is required to express things like “controller” data, “program change” (i.e. articulation switching). Consequently, MIDI has placed constraints on modern musical notation during both composition and performance stages. 
     Some performance constraints are known, and some are unknown. As programming logic is not inherent in the MIDI protocol, and instruments are not standardized across all the commercial parties involved, the “unknown” is more of a by-product of not having good work arounds, or having a system that is too antiquated to deliver the needed standards in a given application. A big issue with MIDI is that while the MIDI communication protocol is standardized, applications using MIDI are not. Thus, a device will know what value to send on a MIDI controller lane, but it is up to the manufacturer to specify what function it will actually perform. For example, CC1 (Continuous Controller #1) is set by MIDI as the “Modulation” controller. It is a standard physical “wheel” controller that goes from 0-127 in value that exists on nearly every physical musical keyboard. The initial intent was to add “vibrato” modulation to a sound and control how wide or fast that vibrato should happen. Nearly every modern software instrument developer uses CC1 to control dynamic expression or even filter a sustained sound, and some software synths still use it to control vibrato. For reference, CC11 is supposed to be used for Expression, and CC71 would typically be used to control filter. 
     Such conventional approaches provide a “wild west” approach to the challenge of how to implement MIDI based on “ease-of-access” on a physical controller. For example, physical MIDI controllers are typically Keyboards that range widely on what knobs, faders and wheels they were manufactured with, but 90% of keyboards always have a pitch and modulation wheel. Modulation wheel is set to CC1 so most software developers use this controller as the primary controller to manipulate samples. MIDI is only a communications protocol between musical devices.—the methods used, while initially designed to be standardized, were not. 
     Articulation switching (sample set switching) and Continuous Controller assignments are two areas that has not been standardized. Many software developers have hacked MIDI in a way to help switch articulations either by a key switch (using a MIDI note to change a set of sounds), or by program changes (less common, but was the designed controller to do instrument or sound set switching.) 
     With computerized score notation, these switches in articulation and controller data could be reflected, if the notation software had knowledge of the keyswitches or program changes, but if the score software did not have knowledge of what the software sampling company designed, how would you know when to write a staccato or marcato marking? For example, if the software knew that MIDI note=01, was switch to pizzacatto, then “pizz” could be written on the score. Same goes for MIDI controller data, if you had three different sources of controller data numbers, commonly used for dynamic (piano/forte) control, how do you determine a “dynamic” on a score based on velocity or CC1 (modulation), CC11 (expression) or CC7 (volume)? 
     As there is no standardization in the music industry on what articulations go where, what velocities happen, and how to trigger samples, etc.) conventional MIDI files are almost useless in the process of creating finalized audio music tracks. 
     The only music-theoretic states in a music composition that the MIDI Standard can reliably send to any notation software application is note placement (e.g. time and pitch) and duration, key, time signature, and tempo. 
     In response to the shortcomings and drawbacks of the MIDI Standard and its continuous controller codes (CC#s), there is a great need in the art to depart from conventions and create new methods and apparatus that will provide increased levels of control, quality, speed and performance desired in most musical production applications. 
     Also, there is a great need in the art to address and overcome the shortcomings and limitations of the outdated MIDI Standard while trying to meet the growing needs of an industry which is seeking to provide artificial intelligence (AI) based support in the field of musical composition, generation and performance, while overcoming the shortcomings and drawbacks of prior art methods and technologies.

     Overview on the Automated Music Performance System of the Present Invention, and the Employment of its Automated Music Performance Engine in Diverse Applications 
       FIGS. 2, 9 and 17  show three high-level system architectures for the automated music performance (AMPE) system of the present invention, each supporting the use of deeply-sampled virtual musical instrument (DS-VMI) libraries and/or digitally-synthesized virtual musical instrument (DS-VMI) libraries driven by music compositions that may be produced or otherwise rendered in any flexible manner as end-user applications may require. 
     As shown and described through the present Patent Specification, a music composition, provided in either sheet music or MIDI-music format or by other means, is supplied by the system user as input through the system user input output (I/O) interface, and used by the Automated Music Performance Engine Subsystem (AMPE) of the present invention, illustrated and described in great technical detail in  FIGS. 2 through 39 , to automatically perform and produce contextually-relevant music, in a composite music file, that is then supplied back to the system user via the system user (I/O) interface. The details of this novel system and its supporting information processes will be described in great technical detail hereinafter. 
     While the illustrative embodiments shown and described herein employ deeply-sampled virtual musical instruments (DS-VMI) containing data files representing notes and sounds produced by audio-sampling techniques described herein, it is understood that such notes and sounds can also be produced or created using digital sound synthesis and modeling methods supported by commercially available software tools including, but not limited to, MOTU® MX4 Synthesis Engine and/or MACHFIVE 3 software products, both by MOTU, Inc. of Cambridge, Mass. 
     In general, and preferably, the automated music performance system of the various illustrative embodiments of the present invention disclosed herein will be realized as an industrial-strength, carrier-class Internet-based network of object-oriented system design, deployed over a global data packet-switched communication network comprising numerous computing systems and networking components, as shown. The system user interface may be supported by a portable, mobile or desktop Web-based client computing system, while the other system components of the network are realized using a global information network architecture. Alternatively, the entire automated music performance system may be realized on a single portable or desktop computing system, as the application may require. In the case of using a global information network to deploy the automated music performance system, the information network of the present invention can be referred to as an Internet-based system network. The Internet-based system network can be implemented using any object-oriented integrated development environment (IDE) such as for example: the Java Platform, Enterprise Edition, or Java EE (formerly J2EE); IBM Websphere; Oracle Weblogic; a non-Java IDE such as Microsoft&#39;s .NET IDE; or other suitably configured development and deployment environments well known in the art. Preferably, although not necessary, the entire system of the present invention would be designed according to object-oriented systems engineering (DOSE) methods using UML-based modeling tools such as ROSE by Rational Software, Inc. using an industry-standard Rational Unified Process (RUP) or Enterprise Unified Process (EUP), both well known in the art. Implementation programming languages can include C, Objective C, C, Java, PHP, Python, Haskell, and other computer programming languages known in the art. Preferably, the system network is deployed as a three-tier server architecture with a double-firewall, and appropriate network switching and routing technologies well known in the art. In some deployments, private/public/hybrid cloud service providers, such Amazon Web Services (AWS), may be used to deploy Kubernetes, an open-source software container/cluster management/orchestration system, for automating deployment, scaling, and management of containerized software applications, such as the enterprise-level applications, as described herein. 
     The innovative system architecture of the automated music performance system of the present invention is inspired by the co-inventors&#39; real-world experience (i) composing musical scores for diverse kinds of media including movies, video-games and the like, (ii) performing music using real and virtual musical instruments of all kinds from around the world, and (iii) developing virtual musical instruments by sampling the sounds produced by real instruments, as well as natural and synthetic audio sound sources identified above, and also synthesizing digital notes and sounds using digital synthesis methods, to create the note/sound sample libraries that support such virtual musical instruments (VMIs) maintained in the automated music performance systems of the present invention. 
     As used herein, the term “virtual musical instrument (VMI)” refers to any sound producing instrument that is capable of producing a musical piece (i.e. a music composition) on a note-by-note and chord-by-chord basis, using (i) a sound sample library of digital audio sampled notes, chords and sequences of notes, recorded from real musical instruments or synthesized using digital sound synthesis methods described above, and/or (ii) a sound sample library of digital audio sounds generated from natural sources (e.g. wind, ocean waves, thunder, babbling brook, etc.) as well as human voices (singing or speaking) and animals producing natural sounds, and sampled and recorded using the sound/audio sampling techniques disclosed herein. Alternatively, such notes and sounds in a virtual musical instrument (VMI) can also be designed, created and produced using digital sound synthesis methods supported using modern sound synthesis software products including, but not limited to, MOTU MX4 and MACHFIVE software products, and the Synclavier® synthesizer systems from Synclavier Digital, and other note/sound design tools, well known in the art. 
     Notably, the methods of music note/sound sampling and synthesis used to building virtual musical instruments (VMIs) for use with the automated music performance system of the present invention, are fundamentally different from prior art loop synthesis methods where many loops, and tracks, of music are pre-recorded and stored in a memory storage device (e.g. a database) and subsequently accessed and combined together, to create a piece of music, and where there is no underlying music theoretic characterization/specification of the notes and chords in the components of music used in such prior art Loop synthesis methods. 
     In marked contrast, strict musical-theoretic specification of each musical event (e.g. note, chord, phrase, sub-phrase, rhythm, beat, measure, melody, and pitch) within a piece of music being automatically composed and generated by the system/machine of the present invention, must be maintained by the system during the entire music composition/generation process in order to practice the virtual music instrument (VMI) synthesis methods in accordance with the principles of the present invention. 
     The automated music performance system of the present invention is a complex system comprised of many subsystems, wherein advanced computational machinery is used to support highly specialized generative processes that support the automated music performance and production process of the present invention. Each of these components serves a vital role in a specific part of the automated music performance engine (AMPE) system of the present invention, and the combination of each component into the automated music composition and generation engine creates a value that is truly greater than the sum of any or all of its parts. A concise and detailed technical description of the structure and functional purpose of each of these subsystem components is provided hereinafter. 
     Regarding the overall timing and control of the subsystems within the system, reference should be made to flow chart set forth in  FIG. 53 , illustrating that the timing of each subsystem during each execution of the automated music performance process for a given music composition provided to the system via its system user interface (e.g. touch-screen GUI, keyboard, application programming interface (API), computer communication interface, etc.). 
     As shown in  FIG. 53 , the first step of the automated music performance process involves receiving a music composition (e.g. in the form of sheet music produced from a music composition or notation system running on a DAW or like system, or a MIDI music composition file generated by a MIDI-enabled instrument, DAW or like system) which the system user wishes to be automatically composed and generated by machine of the present invention. Typically, the music composition data file will be provided through a GUI-based system user system interface subsystem, although it is understood that this system user interface need not be GUI-based, and could use EDI, XML, XML-HTTP and other types information exchange techniques, including APIs (e.g. JASON), where machine-to-machine, or computer-to-computer communications are required to support system users which are machines, or computer-based machines, request automated music composition and generation services from machines practicing the principles of the present invention, disclosed herein. The other steps of the automated music performance process will be described in great detail hereinafter with reference to  FIG. 53 . 
     However, it is to be pointed out at this juncture that various three alternative system architectures have been disclosed and taught herein to illustrate various ways of and means for supplying “music compositions” to the automated music performance engine subsystem of the present invention, for the purpose of automatically generating a nearly infinite variety of possible digital music performances, for each music composition supplied as input to the system via its system interface (e.g. API, GUI-based interface, XML, etc.). 
     The first illustrative embodiment teaches providing sheet-music type music compositions to the automated music performance system of the present invention, and supporting OCR/OMR software techniques to read graphically expressed music performance notation. The second illustrative embodiment teaches providing MIDI-type music compositions to the automated music performance system of the present invention. The third illustrative embodiment teaches providing music experience (MEX) descriptors to an automated music composition engine, and automatically processing the generated music composition to the automatically generate a digital music performance of the music composition. These three illustrative embodiments will be described in great technical detail hereinafter. 
     However, it should be pointed out that there are other sources for providing “music composition” input to the automated music performance engine system of the present invention, accessible of a local area network (LAN) or over a cloud-based wide area network (WAN) as the application may require. For example, a sound recording of a music composition performance can be supplied to an audio-processor programmed for automatically recognizing the notes performed in the performance and generating a music notation of the musical performance recording. Commercially available automatic music transcription software, such as AnthemScore by Lunsversus, Inc., can be adapted to support this illustrative embodiment of the present invention. The output of the automatic music transcription software system can be provided to the music composition pre-processor supported by the first illustrative embodiment of the present invention, to generate music-theoretic state descriptor data (including roles, notes, music metrics and meta data) that is then supplied to the automated music performance system of the present invention. 
     Alternatively, the music composition input can be a sound recording of a tune sung vocally, and this song can be audio-processed and transcribed into a music composition with notes and other performance notation. This music composition can be provided to the music composition pre-processor supported by the first illustrative embodiment of the present invention, to generate music-theoretic state descriptor data (including roles, notes, music metrics and meta data) that is then supplied to the automated music performance system of the present invention. 
     These and other methods of providing a piece of composed music, or performed music, to the automated music performance system of the present invention, will become more apparent hereinafter in view of the present invention disclosure and Claims to Invention appended hereto.

The automated music performance engine subsystem includes: (i) an automated music-theoretic state (MTS) data abstraction subsystem for automatically abstracting all music-theoretic states contained in the music composition and producing a set of music-theoretic state descriptors data (i.e. music composition meta-data) representative thereof; (ii) a deeply-sampled virtual musical instrument (DS-VMI) library management subsystem for managing the sample libraries supporting the deeply-sampled virtual musical instruments to be selected for performance of notes specified in the music composition; and (iii) an automated deeply-sampled virtual musical instrument (DS-VMI) selection and performance subsystem for selecting deeply-sampled virtual musical instruments in the DS-VMI library management subsystem and processing the sampled notes selected from selected deeply-sampled virtual musical instruments using music-theoretic state (MTS) responsive performance rules (i.e. logic), to automatically produce the sampled notes selected for a digital performance of the music composition. The automated music performance engine (AMPE) subsystem transfers the digital performance to the system user interface subsystem for production, review and evaluation.

As shown, the system comprises the various components, comprising: SOC sub-architecture including a multi-core CPU, a multi-core GPU, program memory (DRAM), and a video memory (VRAM); a hard drive (SATA); a LCD/touch-screen display panel; a microphone/speaker; a keyboard; WIFI/Bluetooth network adapters; pitch recognition module/board; and power supply and distribution circuitry; all being integrated around a system bus architecture and supporting controller chips, as shown. 
     The primary function of the multi-core CPU is to carry out program instructions loaded into program memory (e.g. micro-code), while the multi-core GPU will typically receive and execute graphics instructions from the multi-core CPU, although it is possible for both the multi-core CPU and GPU to be realized as a hybrid multi-core CPU/GPU chip where both program and graphics instructions can be implemented within a single IC device, wherein both computing and graphics pipelines are supported, as well as interface circuitry for the LCD/touch-screen display panel, microphone/speaker, keyboard or keypad device, as well as WIFI/Bluetooth (BT) network adapters and the pitch recognition module/circuitry. The purpose of the LCD/touch-screen display panel, microphone/speaker, keyboard or keypad device, as well as WIFI/Bluetooth (BT) network adapters and the pitch recognition module/circuitry will be to support and implement the functions supported by the system interface subsystem, as well as other subsystems employed in the system. 
     Specification of the Automated Music Performance System of the Present Invention, and its Supporting Subsystems Including the Automated Music Performance Engine (AMPE) Subsystem 
       FIG. 2A  illustrates the subsystem architecture of the Automated Deeply-Sampled Virtual Musical Instrument (DS-VMI) Selection and Performance Subsystem employed in the automated music performance system of the present invention, As shown, the Automated Deeply-Sampled Virtual Musical Instrument (DS-VMI) Selection and Performance Subsystem comprises the following subsystems: a Pitch Octave Generation Subsystem; an Instrumentation Subsystem; an Instrument Selector Subsystem; an Digital Audio Retriever Subsystem; a Digital Audio Sample Organizer Subsystem; a Piece Consolidator Subsystem; a Piece Format Translator Subsystem; a Piece Deliver Subsystem; a Feedback Subsystem; and a Music Editability Subsystem. As shown these subsystems are interfaced with the other subsystems deployed within the Automated Music Performance System of the present invention. As will be described in detail below, these subsystems perform specialized functions employed during the automated music performance and production process of the present invention. 
     Specification of the Pitch Octave Generation Subsystem 
       FIG. 2A  shows the Pitch Octave Generation Subsystem used in the Automated Music Performance Engine of the present invention. Frequency, or the number of vibrations per second of a musical pitch, usually measured in Hertz (Hz), is a fundamental building block of any musical performance. The Pitch Octave Generation Subsystem determines the octave, and hence the specific frequency of the pitch, of each note and/or chord in the musical piece. This information is based on either the musical composition state data inputs, computationally-determined value(s), or a combination of both. 
     A melody note octave table can be used in connection with the loaded set of notes to determines the frequency of each note based on its relationship to the other melodic notes and/or harmonic structures in a musical piece. In general, there can be anywhere from 0 to just-short-of infinite number of melody notes in a piece. The system automatically determines this number each music composition and generation cycle. 
     For example, for a note “C,” there might be a one third probability that the C is equivalent to the fourth C on a piano keyboard, a one third probability that the C is equivalent to the fifth C on a piano keyboard, or a one third probability that the C is equivalent to the fifth C on a piano keyboard. 
     The resulting frequencies of the pitches of notes and chords in the musical piece are used during the automated music performance process so as to generate a part of the piece of music being composed. 
     Specification of the Instrumentation Subsystem 
       FIG. 2A  shows the Instrumentation Subsystem used in the Automated Music Performance Engine of the present invention. The Instrumentation Subsystem determines and tracks the instruments and other musical sources catalogued in the DS-VMI library management subsystem that may be utilized in the music performance of any particular music composition. This information is based on either music composition state inputs, compute-determined value(s), or a combination of both, and is a fundamental building block of any musical performance. 
     This subsystem is supported by instrument tables indicating all possibilities of instruments, typically not probabilistic-based, but rather plain tables, providing an inventory of instrument options that may be selected by the system). 
     The parameter programming tables employed in the subsystem will used during the automated music performance process of the present invention. For example, if the music composition state data reflects a “Pop” style, the subsystem might load data sets including Piano, Acoustic Guitar, Electric Guitar, Drum Kit, Electric Bass, and/or Female Vocals. 
     The instruments and other musical sounds selected for the musical piece are used during the automated music performance process of the present invention so as to generate a part of the music composition being digitally performed. 
     Specification of the Instrument Selector Subsystem 
       FIG. 2A  shows the Instrument Selector Subsystem used in the Automated Music Performance Engine of the present invention. The Instrument Selector Subsystem determines the instruments and other musical sounds and/or devices that will be utilized in the musical piece. This information is based on either user inputs (if given), computationally-determined value(s), or a combination of both, and is a fundamental building block of any musical performance. 
     The Instrument Selector Subsystem is supported by an instrument selection table, and parameter selection mechanisms (e.g. random number generator, or another parameter based parameter selector). Using the Instrument Selector Subsystem, instruments may be selected for each piece of music being composed, as follows. Each Instrument group in the instrument selection table has a specific probability of being selected to participate in the piece of music being composed, and these probabilities are independent from the other instrument groups. Within each instrument group, each style of instrument and each instrument has a specific probability of being selected to participate in the piece and these probabilities are independent from the other probabilities. As described herein, other methods of instrument selection may be used during the automated music composition performance process. 
     The instruments and other musical sounds selected by Instrument Selector Subsystem for the musical piece are used during the automated music performance process of the present invention so as to generate a part of the music composition being digitally performed using the DS-VMI library. 
     Specification of the Continuous Controller Processing Subsystem 
       FIG. 2A  shows the Continuous Controller Processing Subsystem used in the Automated Music Performance Engine of the present invention. Continuous Controllers, or musical instructions including, but not limited to, modulation, breath, sustain, portamento, volume, pan position, expression, legato, reverb, tremolo, chorus, frequency cutoff, are a fundamental building block of the digital performance of any music composition provided to the automated music performance system of the present invention. Notably, Continuous Controller (CC) codes are used to control various properties and characteristics of an orchestrated musical composition that fall outside scope of control of instrument orchestration during the music composition process, over the notes and musical structures present in any given piece of orchestrated music. Therefore, the Continuous Controller Processing Subsystem employs models (e.g. including probabilistic parameter tables) that control the characteristics of a digitally performed piece of orchestrated music, namely, modulation, breath, sustain, portamento, volume, pan position, expression, legato, reverb, tremolo, chorus, frequency cutoff, and other characteristics. 
     In general, the Continuous Controller Processing Subsystem automatically determines the controller code and/or similar information of each note to be performed in the digital performance of a music composition, and the automated music performance engine will automatically process selected samples of note to carry out the processing instructions associated with the controller code data reflected in the music-theoretic state data file of the music composition. During operation, the controller code processing subsystem processes the “controller code” information for the notes and chords of the music composition being digitally performed by the DS-VMIs selected from the DS-VMI library management system. This information is based on either music composition inputs, computationally-determined value(s), or a combination of both. 
     The Continuous Controller Processing Subsystem is supported by controller code parameter tables, and parameter selection mechanisms (e.g. random number generator). The form of controller code data is typically given on a scale of 0-127, following the MIDI Standard. Volume (CC 7) of 0 means that there is minimum volume, whereas volume of 127 means that there is maximum volume. Pan (CC 10) of 0 means that the signal is panned hard left, 64 means center, and 127 means hard right. 
     Each instrument, instrument group, and music performance has specific instructions for different processing effects, controller code data, and/or other audio/MIDI manipulating tools being selected for use. With each of the selected manipulating tools, the controller code processing subsystem automatically determines: (i) how detected controller codes expressed in the input music composition will be performed on sampled notes selected from the DS-VMI libraries to affect and/or change the performance of notes in the musical piece, section, phrase, or other structure(s); and how to specifically process selected note samples from the DS-VMI libraries to carry out the controller code performance instructions reflected in the music composition, or more specifically, reflected in the music-theoretic state data file automatically generated for the music composition being digitally performed. 
     The Continuous Controller Processing Subsystem may use instrument, instrument group and piece-wide controller code parameter tables and data sets loaded into the system. For example, instrument and piece-wise continuous controller code (CC) tables (i.e. containing performance rules) for the violin instrument has processing rules for controlling parameters such as: reverb; delay; panning; tremolo, etc. As described herein, other processing methods may be employed during the automated music composition performance process. 
     In general, controller code information expressed in any music composition informs how the music composition is intended to be performed or played during the digital music performance. For example, a piece of composed music orchestrated in a Rock style might have a heavy dose of delay and reverb, whereas a Vocalist might incorporate tremolo into the performance. However, the controller code information expressed in the music composition may be unrelated to the emotion and style characteristics of the music performance, and provided solely to effect timing requests. For example, if a music composition needs to accent a certain moment, regardless of the controller code information thus far, a change in the controller code information, such as moving from a consistent delay to no delay at all, might successfully accomplish this timing request, lending itself to a more musical orchestration in line with the user requests. As it is expected that Controller code will be used frequently in a MIDI-music representation of a music composition to be digitally performed, the Continuous Controller Processing Subsystem will be very useful in many digital music performances using the automated music performance system of the present invention. During operation of the Continuous Controller Processing Subsystem, any continuous controller (CC) code expressed in a music composition for instrumentation purposes will be automatically detected and processed on selected samples from the DS-VMI libraries during the automated music performance process, as described in greater detail hereinbelow. 
     Specification of the Deeply-Sampled Virtual Musical Instrument (DS-VMI) Library Management Subsystem (i.e. Digital Audio Sample Producing Subsystem) and Its Use In The Automated Music Performance System 
     As shown in  FIGS. 2 and 2A , the Automatic Music Performance (and Production) System of the present invention described herein utilizes the libraries of deeply-sampled virtual musical instruments (DS-VMI), to produce digital audio samples of individual notes or audio sounds specified in the musical score representation for each piece of composed music. These digital-sample-synthesized virtual musical instruments shall be referred to as the DS-VMI library management subsystem, which may be thought of as a Digital Audio Sample Producing Subsystem, regardless of the actual audio-sampling and/or digital-sound-synthesis techniques that might be used to produce each digital audio sample (i.e. data file) that represents an individual note or sound to be expressed in any music composition to be digitally performed. 
     In general, to generate music from any piece of composed music, the system needs musical instrument libraries for acoustically realizing the musical events (e.g. pitch events such as notes, rhythm events, and audio sounds) played by virtual instruments and audio sound sources specified in the musical score representation of the piece of composed music. There are many different techniques available for creating, designing and maintaining virtual music instrument libraries, and musical sound libraries, for use with the automated music composition and generation system of the present invention, namely: Digital Audio Sampling Synthesis Methods; Partial Timbre Synthesis Methods, Frequency Modulation (FM) Synthesis Methods; Methods of Sonic Reproduction; and other forms and techniques of Virtual Instrument Synthesis. 
     The preferred method, though not exclusive method, is the Digital Audio Sampling Synthesis Method which involves recording a sound source (such as a real instrument or other audio event) and organizing these samples in an intelligent manner for use in the system of the present invention. In particular, each audio sample contains a single note, or a chord, or a predefined set of notes. Each note, chord and/or predefined set of notes is recorded at a wide range of different volumes, different velocities, different articulations, and different effects, etc. so that a natural recording of every possible use case is captured and available in the sampled instrument library. Each recording is manipulated into a specific audio file format and named and tagged with meta-data with identifying information. Each recording is then saved and stored, preferably, in a database system maintained within or accessible by the automatic music composition and generation system. For example, on an acoustical piano with 88 keys (i.e. notes), it is not unexpected to have over 10,000 separate digital audio samples which, taken together, constitute the fully digitally-sampled piano instrument. During music production, these digitally sampled notes are accessed in real-time to generate the music composed by the system. Within the system of the present invention, these digital audio samples function as the digital audio files that are retrieved and organized by subsystems B 33  and B 34 , as described in detail below. 
     Using the Partial Timbre Synthesis Method, popularized by New England Digital&#39;s SYNCLAVIER Partial-Timbre Music Synthesizer System in the 1980&#39;s, each note along the musical scale that might be played by any given instrument being model (for partial timbre synthesis library) is sampled, and its partial timbre components are stored in digital memory. Then during music production/generation, when the note is played along in a given octave, each partial timbre component is automatically read out from its partial timbre channel and added together, in an analog circuit, with all other channels to synthesize the musical note. The rate at which the partial timbre channels are read out and combined determines the pitch of the produced note. 
     Partial timbre-synthesis techniques are taught in U.S. Pat. Nos. 4,554,855; 4,345,500; and 4,726,067, incorporated by reference. 
     Using state-of-the-art Virtual Instrument Synthesis Methods, such as supported by MOTU&#39;s MachFive 3 Universal Sampler and Virtual Music Instrument Design Tools, musicians can also use digital synthesis methods to design and create custom audio sound libraries for almost any virtual instrument, or sound source, real or imaginable, to support music performance and production in the systems of the present invention. 
     There are other techniques that have been developed for musical note and instrument synthesis, such as FM synthesis, and these technologies can be found employed in various commercial products for virtual instrument design and music production. 
     Specification of the Digital Audio Sample Retriever Subsystem 
       FIG. 2A  shows the Digital Audio Sample Retriever Subsystem used in the Automated Music Performance Engine of the present invention. Digital audio samples, or discrete values (numbers) which represent the amplitude of an audio signal taken at different points in time, are a fundamental building block of any musical performance. The Digital Audio Sample Retriever Subsystem retrieves the individual digital audio samples that are specified in the orchestrated music composition. The Digital Audio Retriever Subsystem is used to locate and retrieve digital audio files in the DS-VMI libraries for the sampled notes specified in the music composition. Various techniques known in the art can be used to implement this subsystem. 
     Specification of the Digital Audio Sample Organizer Subsystem 
       FIG. 2A  shows the Digital Audio Sample Organizer Subsystem used in the Automated Music Performance Engine of the present invention. The Digital Audio Sample Organizer Subsystem organizes and arranges the digital audio samples—digital audio instrument note files-retrieved by the digital audio sample retriever subsystem, and organizes (i.e. assembles) these files in the correct time and space order along the timeline of the music performance, according to the music composition, such that, when consolidated (i.e. finalized) and performed or played from the beginning of the timeline, the entire music composition will be accurately and audibly transmitted and can be heard by others. In short, the digital audio sample organizer subsystem determines the correct placement in time and space of each audio file along the timeline of the musical performance of a music composition. When viewed cumulatively, these audio files create an accurate audio representation of the music performance that has been created or composed/generated. An analogy for this subsystem is the process of following a very specific blueprint (for the musical piece) and creating the physical structure(s) that match the diagram(s) and figure(s) of the blueprint. 
     Specification of the Piece Consolidator Subsystem 
       FIG. 2A  shows the Piece Consolidator Subsystem used in the Automated Music Performance Engine of the present invention. A digital audio file, or a record of captured sound that can be played back, is a fundamental building block of any recorded sound sample. The Piece Consolidator Subsystem collects the digital audio samples from an organized collection of individual audio files obtained from subsystem and consolidates or combines these digital audio files into one or more digital audio file(s) that contain the same or greater amount of information. This process involves examining and determining methods to match waveforms, continuous controller code and/or other manipulation tool data, and additional features of audio files that must be smoothly connected to each other. This digital audio samples to be consolidated by the Piece Consolidator Subsystem are based on either user inputs (i.e. the music composition), computationally-determined value(s), or a combination of both. 
     Specification of the Piece Format Translator Subsystem 
       FIG. 2A  shows the Piece Format Translator Subsystem used in the Automated Music Performance Engine of the present invention. The Piece Format Translator subsystem analyzes the audio representation of the digital performance, and creates new formats of the piece as requested by the system user. Such new formats may include, but are not limited to, MIDI, Video, Alternate Audio, Image, and/or Alternate Text format. This subsystem translates the completed music performance into desired alterative formats requested during the automated music performance process of the present invention. 
     Specification of the Piece Deliver Subsystem 
       FIG. 2A  shows the Piece Deliver Subsystem used in the Automated Music Performance Engine of the present invention. The Piece Deliverer Subsystem transmits the formatted digital audio file(s), representing the music performance, from the system to the system user (either human or computer) requesting the information and/or file(s), typically through the system interface subsystem. 
     Specification of the Feedback Subsystem 
       FIG. 2A  show the Feedback Subsystem used in the Automated Music Performance Engine of the present invention. The primary purpose of the Feedback Subsystem is to accept user and/or computer feedback to improve, on a real-time or quasi-real-time basis, the quality, accuracy, musicality, and other elements of the music performance that is automatically created by the system using the automated music performance automation technology of the present invention. 
     In general, during system operation, the Feedback Subsystem allows for inputs ranging from very specific to very vague, and acts on this feedback accordingly. For example, a user might provide information, or the system might determine on its own accord, that the digital music performance should, for example: (i) include a specific musical instrument or instruments or audio sound sources supported in the DS-VMI libraries; (ii) use a particular performance style or method controlled by performance logic supported in the system; and/or (iii) reflect performance features desired by the or music producer or end-listener. This feedback can be provided through a previously populated list of feedback requests, or an open-ended feedback form, and can be accepted as any word, image, or other representation of the feedback. 
     As shown, the Feedback Subsystem receives various kinds of data which is autonomously analyzed by a Piece Feedback Analyzer supported within Subsystem. In general, the Piece Feedback Analyzer considers all available input, including, but not limited to, autonomous or artificially intelligent measures of quality and accuracy and human or human-assisted measures of quality and accuracy, and determines a suitable response to an analyzed music performance of a music composition. Data outputs from the Piece Feedback Analyzer can be limited to simple binary responses and can be complex, such as dynamic multi-variable and multi-state responses. The analyzer then determines how best to modify a music performance&#39;s rhythmic, harmonic, and other values based on these inputs and analyses. Using the system-feedback architecture of the present invention, the data in any music performance can be transformed after the creation of the music performance. 
     Preferably, the Feedback Subsystem is capable of performing Autonomous Confirmation Analysis, which is a quality assurance (QA)/self-checking process, whereby the system examines the digital performance of a music composition that was generated, compares the music performance against the original system inputs (i.e. input music composition and abstracted music-theoretic state data), and confirms that all attributes of the digital performance that were requested, have been successfully created and delivered in the music performance, and that the resultant digital performance is unique. This process is important to ensure that all music performances that are sent to a user are of sufficient quality and will match or surpass any user&#39;s performance expectations. 
     As shown, the Feedback Subsystem analyzes the digital audio file and additional performance formats to determine and confirm (i) that all attributes of the requested music performance are accurately delivered, (ii) that digital audio file and additional performance formats are analyzed to determine and confirm “uniqueness” of the musical performance, and (iii) the system user analyzes the audio file and/or additional performance formats, during the automated music performance process of the present invention. A unique music performance of a particular music composition is one that is different from all other music performance of the particular music composition. Uniqueness can be measured by comparing all attributes of a music performance to all attributes of all other music performances in search of an existing musical performance that nullifies the new performance&#39;s uniqueness. 
     If music performance uniqueness is not successfully confirmed, then the feedback subsystem modifies the inputted musical experience descriptors and/or subsystem music-theoretic parameters, and then restarts the automated music performance process to recreate the digital music performance. If musical performance uniqueness is successfully confirmed, then the feedback subsystem performs a User Confirmation Analysis, which is a feedback and editing process, whereby a user receives the music performance produced by the system and determines what to do next, for example: accept the current music performance; request a new music performance based on the same inputs; or request a new or modified music performance based on modified inputs. This is the point in the system&#39;s operation that allows for editability of a created music performance, equal to providing feedback to a human performer (or music conductor) and setting him/her off to enact the change requests. 
     Thereafter, the system user (e.g. human listener or automated machine analyzer) analyzes the audio file and/or additional performance formats and determines whether or not feedback is necessary. To perform this analysis, the system user can (i) listen to the music performance in part or in whole, (ii) view the music composition score file (represented with standard MIDI conventions) supporting the music performance, and/or (iii) interact with the music performance so that the user can fully experience the music performance and decide on how it might be changed in particular ways during the music performance regeneration process. 
     In the event that feedback is not determined to be necessary for a particular music performance, then the system user either (i) continues with the current music performance, or (ii) uses the exact same user-supplied music composition and associated parameters to create a new music performance for the music composition using the system. In the event that feedback is determined to be necessary, then the system user provides/supplied desired feedback to the system, and regenerates the music performance using the automated music performance system. 
     In the event the system users desires to provide feedback to the system via the GUI of the system interface subsystem, then a number of feedback options will be typically made available to the system user through a system menu supporting, for example, a set of pull-down menus designed to solicit user input in a simple and intuitive manner. 
     Specification of the Music Editability Subsystem 
       FIG. 2A  shows the Music Editability Subsystem used in the Automated Music Performance Engine of the present invention. The Music Editability Subsystem allows the digital music performance to be edited and modified until the end user or computer is satisfied with the result. The subsystem or user can change the inputs, and in response, input and output results and data from subsystem can modify the digital performance music of the music composition. The Music Editability Subsystem incorporates the information from subsystem, and also allows for separate, non-feedback related information to be included. For example, the system user might change the volume of each individual instrument and/or change the instrumentation of the digital music performance, and further tailor the performance of selected instruments as desired. The system user may also request to restart, rerun, modify and/or recreate the digital music performance during the automated music performance process of the present invention. 
     Specification of the Preference Saver Subsystem 
       FIG. 2A  shows the Preference Saver Subsystem used in the Automated Music Performance Engine of the present invention. The Preference Saver Subsystem modifies and/or changes, and then saves data elements used within the system, and distributes this data to the subsystems of the system, in order or to better reflect the preferences of any given system user. This allows the music performance to be regenerated following the desired changes and to allow the subsystems to adjust the data sets, data tables, and other information to more accurately reflect the user&#39;s musical and non-music performance preferences moving forward. 
     Specification of the Method of Automated Digital Music Performance Generation Using Deeply-Sampled Virtual Musical Instrument Libraries and Contextually-Aware (I.E. Music State Aware) Performance Logic Supported in the Automated Music Performance System 
       FIG. 3  describes a method of automated digital music performance generation using deeply-sampled virtual musical instrument libraries and contextually-aware (i.e. music state aware) performance logic supported in the automated music performance system shown in  FIG. 2 .

     Specification of the Method of Generating a Digital Performance of a Musical Composition Using the Automated Music Composition and Performance System 
       FIG. 4  describes a method of generating a digital performance of a composed piece of music (i.e. a musical composition) using the automated music composition and performance system shown in  FIGS. 2, 2A and 2B . As shown, the method comprising the steps of (a) producing a digital representation of an automatically composed piece of music to be orchestrated and arranged for a digital performance using selected deeply-sampled virtual musical instruments performed using music-theoretic state (MTS) responsive performance rules, (b) automatically determining the music-theoretic states of music in a music composition along its timeline, and producing a set of timeline-indexed music-theoretic state descriptor data (i.e. roles, notes, metrics and meta-data) for use in the automated music performance system, (c) based on the roles abstracted from the music composition, selecting types of deeply-sampled virtual musical instruments available for digital performance of the music composition in a deeply-sampled virtual musical instrument (DS-VMI) library management system, (d) using the set of music theoretic-state meta-data descriptor data to automatically select sampled notes from deeply-sampled virtual musical instrument libraries, and using music-theoretic state responsive performance rules to process the selected sampled notes to generate the notes for a digital performance of the music composition, (e) assembling and finalizing the processed sampled notes in the generated digital performance of the music composition, and (f) producing the performed sampled notes in the digital performance of the music composition, for review and evaluation by human listeners. 
     Specification of the Process of Automated Selection of Sampled Notes in Deeply-Sampled Virtual Musical Instrument (DS-VMI) Libraries to Produce the Sampled Notes for the Digital Performance of a Composed Piece of Music 
       FIG. 5 . illustrates the process of automated selection of sampled notes in deeply-sampled virtual musical instrument (DS-VMI) libraries to produce the notes for the digital performance of a composed piece of music in accordance with the principles of the present invention, involving (a) the parsing and analyzing the music composition to abstract music-theoretic state descriptor data (i.e. music composition meta data), (b) formatting the music-theoretic state descriptor data (i.e. music composition meta-data) abstracted from the music composition (or transforming the music-theoretic state descriptor data and music instrument performance rules in the DS-VMI library management subsystem, to support musical arrangement and/or performance style transformations as described in the fourth system embodiment of the present invention, (c) using music-theoretic state descriptor data and automated virtual musical instrument contracting subsystem to select deeply-sampled virtual musical instruments (DS-VMI) for the performance of the music composition, (d) using music-theoretic state descriptor data to select sampled from selected deeply-sampled virtual musical instruments, (e) processing samples using music-theoretic state (MTS) responsive performance logic maintained in the DS-VMI library management subsystem so as to produce note samples for the digital performance, and (f) assembling and finalizing the notes in the digital performance of the music composition, for production and review.

     Method of Operation of the Automated Music Performance System of the First Illustrative Embodiment of the Present Invention 
       FIG. 7  describes the method of operation of the automated music performance system of the first illustrative embodiment of the present invention, shown in  FIGS. 2 through 6 . 
     As shown in Block A of  FIG. 7 , the process involves receives a sheet-based music composition as system input, and extracts musical information from the sheet music using OCR (Optical Character Recognition) and/or OMR (Optical Music Recognition) processing techniques well known in the art and described in WIKI link https://en.wikipedia.org/wiki/Optical music recognition incorporated herein by reference. In general, each sheet-type music composition to be provided as input to the system can be formatted in any suitable format and language for OCR and other OMR processing in accordance with the principles of the present invention. 
     Suitable OCR/OMR-enabled commercial music score composition programs such as Sibelius Scorewriter Program by Sibelius Software Limited; Finale Music Notation and Scorewriter Software by MakeMusic, Inc.; MuseScore Composition and Notation Program by MuseScore BVBA www.musescore.org; and Capella Music Notation or Scorewriter Program by Capella Software AG; can be used to scan and read sheet music and generate an electronic file format that can be subsequently processed by the automated music performance system in accordance with the principles of the present invention disclosed and taught herein. 
     As shown in Block B of  FIG. 7 , the method involves collecting music composition state data from Block A to determine music-theoretic information from the music composition, such as the key, tempo, duration of the musical piece, and analyze form (e.g. phrases and sections) and execute and store chord analysis. 
       FIG. 8  describes an exemplary set of music-theoretic state descriptors (e.g. parameters) that are automatically evaluated during Block B within each music theoretic state descriptor file (for a given music composition) by the automated music performance subsystem of the present invention. The purpose of this automated data evaluation is to automatically select at least one instrument type for each Role abstracted from the music composition, and also to automatically select the sampled sound files (e.g. sampled notes) for the selected instrument type represented in the deeply-sampled virtual musical instrument library (DS-VMI) subsystem of the present invention, and process them as required by the performance logic developed for the sampled notes in the selected DS-VMI libraries. 
     As shown in Block C of  FIG. 7 , the method involves processing the music-theoretic state data collected at Block B and executing a Role Analysis comprising: (a) Determining the Position of notes in a measure, phrase, section, piece; (b) Determining the Relation of Notes of Precedence and Antecedence; (c) Determining Assigned MIDI Note Values (A1, B2, etc.); (d) Reading the duration of Notes; (e) Evaluating the position of Notes in relation to strong vs weak beats; (f) Reading historical standard notation practices for possible articulation usages; (g) Reading historical standard notation practices for dynamics (i.e. automation); and (h) Determining the Position of Notes in a chord for determining voice-part extraction (optional). The output of the Role Analyzer are Roles assigned to group of Notes contained in the music composition. 
     As shown in Block D of  FIG. 7 , the method involves sending music-theoretic state data collected at Block B to a composition note parser to parse out the time-indexed notes contained in the music composition. 
     As shown in Block E of  FIG. 7 , the method involves assigning Instrument Types to abstracted Roles and Notes to be performed (i.e. “Performances”). 
     As shown in Block F of  FIG. 7 , the method involves using the Roles and Note Performance obtained at Blocks C and E to generate performance automation from the analysis. 
     As shown in Block G of  FIG. 7 , the method involves generalizing the Note Data for the Instrument Type and Note Performance selected by the automated music performance subsystem. 
     As shown in Block H of  FIG. 7 , the method involves assigning sampled instruments (i.e. DS-VMI sample libraries) to the selected Instrument Types required by the Roles identified for the digital performance of the input music composition. 
     As shown in Block I of  FIG. 7 , the process involves generating a mix definition for audio track production to produce the final digital performance for all notes and roles specified in the music composition. For purposes of the present invention, a mix definition is the instruction set for the audio engine in the system to play the correct samples at a specified time with DSP, Velocity, Volume, CC, etc. and combine all the audio together to generate an audio track(s). 
     Music-Theoretic State Descriptors Automatically Evaluated by the Automated Music Performance System of the First Illustrative Embodiment During Automated Selection of Musical Instruments and Sampled Notes During Each Digital Performance 
       FIG. 8  describes a set of music-theoretic state descriptors (e.g. parameters) that are automatically evaluated within each music-theoretic state descriptor file (for a given music composition) by the automated music performance subsystem of the present invention deployed in the system of  FIG. 2 , so as to (i) automatically select at least one instrument for each Role abstracted from the music composition, and also (ii) automatically select and sample the sound files (e.g. sampled notes) for the selected instrument type represented in and supported by the deeply-sampled virtual musical instrument library (DS-VMI) subsystem of the present invention. 
     The function of DS-VMI behavior-sample selection/choosing supported by the automated DS-VMI Selection and Performance Subsystem shown in  FIG. 2  involves automated evaluation of all of the Role-indexed/organized note data, music metric data, and music meta-data collected during automated analysis of the music composition to be digitally performed. In the preferred embodiment, this automated intelligent evaluation of music state data associated with any given music composition to be digitally performed will be realized using the rich set of instrument performance rules (i.e. performance logic) written and deployed within each DS-VMI Library supported within the automated music performance engine of the present invention. 
     When carrying out this automated data evaluation process, for the purpose of automatically selecting/choosing instrument types and sampled notes and appropriate sample note processing, the music-theoretic state data descriptor file schematically depicted in  FIG. 29  will be supplied as subsystem input, the Automated DS-VMI Selection and Performance Subsystem and the Automated Virtual Musical Instrument Contracting Subsystem of  FIG. 2  will (i) review each Performance Rule in the DS-VMI Library and (ii) check the music data states reflected in the input music-theoretic data descriptor file depicted in  FIG. 29  to automatically determine Instrument Performance Rules (i.e. Logic) to execute in order to generate the rendered notes of a digital music performance to be produced from the automated music performance subsystem. This data evaluation process will be carried out in a syllogistic manner, to determine when and where “If X, then Y” performance rule conditions are satisfied and instrument and note selections should be made in a real-time manner. Below are the various levels of data evaluation performed by this intelligent process within the automated music performance system during automated instrument and note selection and modification.
         1. Primary Evaluation Level—this is the initial level of processing supported by which DS-VMI library management system which commences the evaluation of note data.
           a. Rhythmic density by tempo—Initial step to determine selections of behavior and articulation types based on how dense the notes are in a given tempo. For example, if a tempo was at 140 and 16 th  notes were detected, then performances of a shaker may ignore every other 16 th  note, or choose a sample set that can articulate fast enough to perform those note samples.   b. Duration of notes—determine how long each rhythmic assignment should hold out (sustain) for, important for determining release samples, intestinal samples, guitar string relationships, etc.   c. MIDI note value—determination of the pitch assignments of the duration of notes   d. Dynamics—determination of what velocity to play the note at (and select the correct timbre/volume of a sample)   
           2. Static Note Relationships—this is the process of analyzing where the notes come in relation to time and space
           a. Position of notes in a chord—where the note is in relation to the root, third, fifth, etc.   b. Meter and position of strong and weak beats—determine if compound or simple meter, where the strong and weak beats are   c. Position of notes in a measure—determine where the notes are in relation to the strong and weak beats based on meter   d. Position of notes in a phrase—determine where the notes are in relation to a phrase (a group of measures)   e. Position of notes in a section—determine where the notes are in relation to a section (a group of phrases)   f. Position of notes in a region—determine where the notes are in relation to a region (a group of sections)   
           3. Situational Relationship—this establishes the modifiers (behaviors of an instrument) that allow for alternate sample selections (hit vs rim-shot, staccato vs spiccato, etc.)
           a. MIDI note value precedence and antecedence—evaluate what notes come before and after the current note and choose to alter the sample selection with a difference behavior type   b. Position or existence of notes from other roles—determine the other notes written in other instrument parts (roles) and alter sample selection (or don&#39;t play) ex: instruments are snare, kick and hi-hat, if kick is playing don&#39;t play the snare hit sample and only play a closed rim hit on the hi-hat   c. Relation of sections to each other—evaluate what has been played before in a previous section and either copy or alter the sample selection.   d. Accents—evaluate any system-wide musical accents and alter samples (velocity or sample selection) based on this modifier.   e. Timing based rhythms—based on 1.a resolve any samples that may not be able to perform the rhythms properly and choose an approved sample set, or not play.   
           4. Instrument Selection—this is the actual sample bank (i.e. DS-VMI library) that makes up a selected virtual music instrument. Note that the Instruments are assigned to the Role before notes are sent from the above automated evaluation stage. This stage in the process allows the system to be aware or cognizant of the Instruments chosen and to make sample Behavior modifications as Instruments are added or taken away.
           a. What Instruments are available—all Instruments that exist in a “band” different notes may be sent to other instruments if some instruments don&#39;t exist so important parts are covered, this can change register of the instrument as well as sample selection   b. What Instruments are playing—all Instruments that are playing, this determines if certain Instruments should not play, not play as much, or play the same as another Instrument   c. What Instruments should/might play—all the Instruments available that are not playing, but could help double another instrument.   d. What Instruments are assigned to a Role—this is the music composition part that the Instrument is playing, e.g. “am I a Background instrument”, “do I only play a pedal note”, “am I a lead”   e. How many Instruments are available—determines density of parts, volume, panning and other automation considerations to a sample performance.

The automated music performance engine (AMPE) subsystem ultimately transfers the digital performance to the system user interface subsystem for production, review and evaluation.

     Method of Operation of the Automated Music Performance System of the Third Illustrative Embodiment of the Present Invention 
       FIG. 22  describes the method of operation of the automated music performance system of the first illustrative embodiment of the present invention, shown in  FIGS. 17 through 21 . 
     As shown at Block A in  FIG. 22 , the method involves providing a musical experience descriptor (MEX) template containing input MEX descriptor data to an automated music composition engine of the present invention. 
     As shown at Block B in  FIG. 22 , the method involves establishing an input timeline and generating note data for a music composition automatically generated using the automated music composition engine provided with the MEX descriptor template data input. 
     As shown at Block C in  FIG. 22 , the method involves performing the following functions by evaluating the note data generated at Block B, namely: (a) Creating/generating Roles for specific groups of notes; (b) Assigning Instrument Types to the Roles; (c) Assigning Note Performances to Instrument Types; (d) Assigning Roles to DSP routing; (e) Assigning Trim and Gain to Roles; and (f) Assigning Automation Logic to Roles. 
       FIG. 23  shows a set of music-theoretic state descriptors (e.g. parameters) that are automatically evaluated at Blocks C, D, E, F and G (for a given music composition) by the automated music performance subsystem of the present invention so as to (i) automatically select at least one Instrument Type for each Role abstracted from the automated music composition analysis, and also (ii) automatically select and sample the sound sample files (e.g. sampled notes) for the selected Instrument Type that is represented in and supported by the deeply-sampled virtual musical instrument library (DS-VMI) subsystem of the present invention.

     Music-Theoretic State Descriptors Automatically Evaluated by the Automated Music Performance System of the Third Illustrative Embodiment During Automated Selection of Musical Instruments and Sampled Notes During Each Digital Performance 
       FIG. 23  describes a set of music-theoretic state descriptors (e.g. parameters) that are automatically evaluated within each music-theoretic state descriptor file (for a given music composition) by the automated music performance subsystem of the present invention deployed in the system of  FIG. 17 , so as to (i) automatically select at least one instrument for each Role abstracted from the music composition, and also (ii) automatically select and sample the sound files (e.g. sampled notes) for the selected instrument type represented in and supported by the deeply-sampled virtual musical instrument library (DS-VMI) subsystem of the present invention. 
     The function of DS-VMI behavior-sample choosing supported by the automated DS-VMI Selection and Performance Subsystem shown in  FIG. 17  involves automated evaluation of all of the Role-indexed/organized note data, music metric data, and music meta-data collected during automated analysis of the music composition to be digitally performed. In the preferred embodiment, this automated intelligent evaluation of music state data associated with any given music composition to be digitally performed will be realized using the rich set of instrument performance rules (i.e. performance logic) written and deployed within each DS-VMI Library supported within the automated music performance engine of the present invention. 
     When carrying out this automated data evaluation process, for the purpose of automatically selecting/choosing instrument types and sampled notes and appropriate sample note processing, the music-theoretic state data descriptor file schematically depicted in  FIG. 39  will be supplied as subsystem input, the Automated DS-VMI Selection and Performance Subsystem and the Automated Virtual Musical Instrument Contracting Subsystem of  FIG. 17  will (i) review each Performance Rule in the DS-VMI Library and (ii) check the music data states reflected in the input music-theoretic data descriptor file depicted in  FIG. 39  to automatically determine Instrument Performance Rules (i.e. Logic) to execute in order to generate the rendered notes of a digital music performance to be produced from the automated music performance subsystem. This data evaluation process will be carried out in a syllogistic manner, to determine when and where “If X, then Y” performance rule conditions are satisfied and instrument and note selections should be made in a real-time manner. Below are the various levels of data evaluation performed by this intelligent process within the automated music performance system during automated instrument and note selection and modification.
         1. Primary Evaluation Level—this is the initial level by which DS-VMI system starts the evaluation of notes.
           a. Rhythmic density by tempo—Initial step to determine selections of behavior and articulation types based on how dense the notes are in a given tempo. For example if   b. tempo was at 140 and 16 th  notes were detected performances of a shaker may ignore every other 16 th  note, or choose a sample set that can articulate fast enough to perform those samples.   c. Duration of notes—how long each rhythmic assignment should hold out (sustain) for, important for determining release samples, intestinal samples, guitar string relationships, etc.   d. MIDI note value—the pitch assignments of the duration of notes   e. Dynamics—at what velocity to play the note at (select the correct timbre/volume of a sample)   
           2. Static Note Relationships—this is the process of analyzing where the notes come in relation to time and space
           a. Position of notes in a chord—where the note is in relation to the root, third, fifth, etc.   b. Meter and position of strong and weak beats—determine if compound or simple meter, where the strong and weak beats are   c. Position of notes in a measure—determine where the notes are in relation to the strong and weak beats based on meter   d. Position of notes in a phrase—determine where the notes are in relation to a phrase (a group of measures)   e. Position of notes in a section—determine where the notes are in relation to a section (a group of phrases)   f Position of notes in a region—determine where the notes are in relation to a region (a group of sections)   
           3. Situational Relationship—this establishes the modifiers (behaviors of an instrument) that allow for alternate sample selections (hit vs rim-shot, staccato vs spiccato, etc.)
           a. MIDI note value precedence and antecedence—evaluate what notes come before and after the current note and choose to alter the sample selection with a difference behavior type   b. Position or existence of notes from other roles—determine the other notes written in other instrument parts (roles) and alter sample selection (or don&#39;t play) ex: instruments are snare, kick and hi-hat, if kick is playing don&#39;t play the snare hit sample and only play a closed rim hit on the hi-hat   c. Relation of sections to each other—evaluate what has been played before in a previous section and either copy or alter the sample selection.   d. Accents—evaluate any system-wide musical accents and alter samples (velocity or sample selection) based on this modifier.   e. Timing based rhythms—based on 1.a resolve any samples that may not be able to perform the rhythms properly and choose an approved sample set, or not play.   
           4. Instrument Selection—this is the actual sample bank that makes up a selected instrument. Note that the Instruments are assigned to the Role before notes are sent from the above automated evaluation stage. This stage in the process allows the system to be aware of the instruments chosen and to make sample behavior modifications as instruments are added or taken away.
           a. What instruments are available—all instruments that exist in a “band”—different notes may be sent to other instruments if some instruments don&#39;t exist so important parts are covered, this can change register of the instrument as well as sample selection   b. What instruments are playing—all instruments that are playing, this determines if certain instruments should not play, not play as much, or play the same as another instrument   c. What instruments should/might play—all the instruments available that are not playing, but could help double another instrument.
 
Specification of the Generalized Method of Automatically Abstracting Music-Theoretic State Descriptors, Including Roles, Notes, Music Metrics and Meta-Data, from a Piece of Composed Music Prior to Submission to the Automated Digital Music Performance System of the Present Invention
   
               

       FIG. 24  describes the process of automatically abstracting music-theoretic states, including Roles, Note data, Music Metrics and Meta-Data, from a music composition to be digitally performed by the system of the present invention, and automatically producing music-theoretic state descriptor data along the timeline of the music composition, for use in driving the automated music performance system of the present invention. 
     The steps involved in this process will depend on the particular format of the music composition requiring automated music-theoretic note and state analysis, as taught herein and illustrated throughout the Drawings and Specification. In the three illustrative system embodiments, slightly different methods will be employed to accommodate the different formats of music composition under automated analysis. However, each music composition under automated analysis will typically employ similar methods to automatically abstract time-indexed note data, music metrics, and meta-data contained in the music composition, all of which is preferably organized under abstracted Musical Roles (or Parts) to be performed by selected Virtual Musical Instruments (or MIDI-controlled Real Musical Instruments MIDI-RMI) during an automated digital music performance of the analyzed music composition. The details of each of these music composition analysis methods, constructed in accordance with the illustrative embodiments of the present invention, will be described in detail below. 
     Method of Generating a Music-Theoretic State Descriptor Representation for a Sheet-Type Music Composition to be Used in the Automated Music Performance System During Selection, Assembling and Performance of Sampled Notes from Deeply-Sampled Virtual Musical Instruments Supported by the Automated Music Performance System of the Present Invention 
       FIGS. 25 through 29  describes a method of automatically processing a sheet-type music composition file provided as input in a conventional music notation format, determining the music-theoretic states thereof including notes, music metrics and meta-data organized by Roles automatically abstracted from the music composition, and generating a music-theoretic state descriptor data file containing time-line-indexed note data, music metrics and meta-data organized by Roles (and arranged in data lanes) for use with the automated music performance system of present invention. 
       FIG. 26  describes the automated OCR-based music composition analysis method adapted for use with the automated music performance system of the first illustrative embodiment, and designed for processing sheet-music-type music compositions, showing the bed, play bass, etc.), and How many instruments are available. 
     As shown at Block A in  FIG. 26 , the process involves receiving a piece of sheet-type music composition input and OCR/OCM processing the file to abstract and collect music state data including note data, music state data and meta-data abstracted from the music composition file to be digitally performed. 
     At Block B in  FIG. 26 , the method involves (a) analyzing the key, tempo and duration of the piece, (b) analyzing the form of phrases and sections, (c) executing and shorting chord analysis, and (d) computing music metrics based on the parameters specified in  FIG. 27 , and described hereinabove. 
     In  FIG. 26A , there is shown a basic processing flow chart for any conventional OCR music composition algorithm designed to reconstruct the musical notation for any OCR scanned music composition in sheet music format (i.e. sheet music composition). Under the Music Notation Reconstruction Block in  FIG. 26A , there is a “Music-Theoretic State” Data Abstraction Stage which supports and performs the data recognition and abstraction functions described in  FIG. 27 . 
     As shown at Block C in  FIG. 26 , the method involves abstracting Roles from analyzed music-theoretic state data 
     As shown at Block D in  FIG. 26 , the method involves parsing note data based on Roles abstracted from the music composition, and sending this data to the output of the music composition analyzer. 
       FIG. 27  specifies all music-theoretic state descriptors that might be automatically abstracted/determined from any automatically-analyzed music composition during the preprocessing stage of the automated music performance process of the present invention. The exemplary set of music-theoretic state descriptors shown in  FIG. 27  include, but are not limited to: Rhythmic Density by Tempo; Duration of Notes; MIDI Note Value (A1, B2, etc.), Dynamics; Static Note Relations, such as, Position of Notes in a Chord, Meter and Position of Strong and Weak Notes, Position of Notes in a Measure, Position of Notes in a Phrase, Position of Notes in a Section, Position of Notes in a Region; Situational Relationships such as MIDI Note Value Precedence and Antecedence, Position or Existence of Notes from other Instruments Lanes, Relation of Sections to Each Other, Note Modifiers (Accents); Instrument Specification, such as, What Instruments are Playing, What Instruments Should or Might Be Played, Position of Notes from Other Instruments, Meter and Position of Downbeats and Beats, Tempo Based Rhythms, What Instruments are assigned to a role (e.g. Play in background, play as a bed, play bass, etc.), and How many instruments are available. 
     In accordance with the principles of the present invention, all deeply-sampled virtual musical instruments in the DS-VMI library management subsystem are provided with some level of intelligent performance control via coding (aka sample selection/playback) written as performance logic for them, whether it&#39;s a simple “Hit” of a Snare or the complex “Strum” of a Guitar. The performance dictates what sample to trigger and how to trigger with note, velocity, manual, automation, and articulation information. To reiterate: the composer writes out the notes in the music composition, and when to play those notes, and then the automated music performance system adapts those notes on how to playback those samples. 
     In order to make a deeply-sampled virtual musical instrument (DS-VMI) sound realistic, the automated music performance system does not need to interpret a direct note-for-note playback, but rather is capable of calling many instruments and extrapolating sampled note information to choose a correct sample playback at any instant in time. For instance, if the composer says play a G chord on a downbeat, then a possible performance written for the guitar might be to build the chord as “E1 String: 3 rd  fret (G), A1 String: 2 nd  Fret (B), D2 String: Open (D), G2 String: Open (G), B2 String: Open (B), E3 String: 3 rd  fret (G)”. Then select the samples based on each separately recorded string, set a velocity range to trigger in, modifier type: Open (choices: Mute, Dead or Open) which strum direction: Down (choices: up or down). The samples would be requested and played in the audio engine, and then a timing differential would be added between each string to make the performance of the chord occur on the downbeat. If there was a G on the next beat, then the automated music performance system would play the same configuration, but may choose the up sample sets and start from the top E3 string, down through to the E1 string. 
     Each virtual musical instrument in the automated music performance system has a specific instrument performance logic (i.e. “a Performance) based on its parent template. Notably, Performances are actually set to Instruments specifically, and can be applied in batches based on their template/instrument_type association. 
     Some musical instruments could have one performance assigned, or have hundreds of performances assigned. Each performance adds dimensionality to an instrument&#39;s capabilities. The automated music performance system of the present invention interprets what the music composition contains in terms of its full music-theoretic states of music, along its entire timeline. The music composition contains chords and/or notes with timing information in them. To support its contextual-awareness capacities, the automated music performance system includes automated music-theoretic state abstraction processing algorithm(s) which automatically analyze what those notes are in the music composition to be digitally performed, and formulas can be use used around these notes to help determine a playback scheme for triggering the samples through an audio mixing engine supported within the automated music performance system. 
     As will be described in greater detail hereinafter, a human or machine composer transmits a music composition to be digitally performed to the automated music performance system of the present invention. The music composition containing note data is automatically analyzed by the system to generate music-theoretic state data (i.e. music composition meta-data) such as: roles, note data, music metric data such as the position of notes within a song structure (chorus, verse, etc.), mode/key, chords, notes and their position within a measure, how long the notes are held (note duration) and when they are performed, and other forms of music composition meta-data. 
     By analyzing the music composition, the automated music performance system automatically abstracts and organizes collected note data, music metric data, music composition meta-data within an enveloped assigned an abstracted Musical Role (or Part), so as to inform the automated music performance system of the notes and possible music-theoretic states contained in the music composition such as, for example: 
     Duration of Notes: 
     
         
         
           
             1. Duration can tell what type of sample to trigger at the end of a sample (i.e. short releases). 
             2. Duration can also have several overriding parameters that can modify the note duration to either create a shorter (staccato-like) or longer (legato-like) performance. 
             3. Duration also allows for behavior types of monophonic instruments for portamento type/glide type. 
             4. Duration is also aware of any type of downbeat offset and how to manipulate the release of a performance based on when the start of the note is triggered vs when the note is perceived as the “downbeat”
 
Position of Notes in Time:
 
           
         
       
    
     The performance tool can isolate where items are within 3 levels of granularity. Measure, Phrase, and Section. The composer creates music measure by measure, assembles those measures into phrases and then the phrases belong to sections. The performance system uses the positions of notes to determine a velocity, articulation choice, or a manual switch. These are chosen through deterministic, stochastic, or purely random methods/algorithms. 
     Position of Notes in a Chord: 
     When a composer sends out a chord to a specific deeply-sampled virtual musical instrument, the automated music performance system can isolate a note performance based on what notes can be assigned to the deeply-sampled virtual musical instrument. Understanding the note relationship within the chord allows the automated music performance system, with its music-theoretic state responsive performance rules, to automatically process and change specific tuning to a sample, a velocity change, how the chord should be voiced, which string to play, or even what note in the chord to play (if it&#39;s a monophonic virtual musical instrument). Assigned Instrument Roles can help orchestration decisions. 
     Note Modifiers: 
     Accents: This is an extra layer of data that is written from the composer to unify a layer of accents (or strong-beat) control that allow for sample selection on quick dynamic changes (on single beats). For example switching from a regular stick-hit on a snare to a rim-shot, or changing the velocity of a piano from mf to ff. 
     Dynamics: 
     Dynamics, with regards to sample selection, can request playback, where to blend the two sample sets together, as well as different recorded sampled manuals. For example: Violins at ppp may select a “con sordino” (or with-mute) sample set. Or when moving from pp top on a piano—start blending two samples together to create the timbral shift. Dynamics can also inform control data explained further below. 
     Note Value Precedence and Antecedence: 
     Equipped with music-theoretic state descriptor data streams and logical performance rules assigned to deeply-sampled virtual musical instruments libraries, the automated music performance system of the present invention is provided with an artificial intelligence and awareness of notes that come before and come after any given note along the timeline of a music composition being digitally performed using the DS-VMI libraries. This capacity helps inform the automated music performance system when to switch between articulations of sampled notes, as well as when to use legato, perform a note-off release, then a note on (repeated round robin), or when to choose a transition effect. For example, moving from a higher hand-shape on a guitar to a lower hand shape, the automated music performance system can then insert the transition effect of “finger noise-down by middle distance.” 
     Instrumentation Awareness: 
     Role: When an instrument is assigned into a Role, this allows for other instruments to know that instruments importance, where it fits within the structure of note assignments, performance assignment, and what sample sets that should be chosen. For example, if a string part is assigned a fast, articulated performance, the sample set chosen would be short note recordings. Examples of Roles are specified in  FIG. 28   
     Availability: Knowing what instruments are available as to assign instrument performances to more valuable and important roles. For example, when two guitars are assigned, one takes a lead, mono role, while the other supports rhythm. When only one guitar is selected, which role is more important and move to that role (or move between the two based on material type (song structure location). 
     What is playing: This is being aware of which other instruments are playing which Roles helps to determine range, volume and activity level assigned to an instrument performance. 
     Physical Limitations: “The four handed drummer” problem—Limiting the voices based on physical constraints of the instrument, while allowing the users to select more than one-type of item. For example, if there are 4 cymbals, 1 hi-hat, 1 snare, and 4 toms and a kick: if there is a fill in a drum part, don&#39;t play more than 2 “hand hits” and 2 “foot hits” at one time. 
     Position of Notes from other Notes: This allows for complicated and orchestration decisions based on available notes, what other instruments are playing those notes, position in Role type and importance of that Role. 
     Structural Awareness: 
     Relation of Sections: Similar to how notes within a section are selected, knowing which sections have happened and what permutation of a section you are in can inform sample changes, such as dynamic shifts, moving from a type of articulation to another type. For example, switching from the first verse to the second, you would have the piano play “pedal” on the first verse, but maybe be drier or heavier on the second verse and play “regular” or “without pedal”. 
     Meter and position of Downbeats and Beats: Similar to how samples are selected from an accent lane, knowing what meter, where the strong vs weak beats are and the relation with in a part of a phrase will determine what sample could be selected. 
     Tempo: 
     Having knowledge of the music-theoretic parameter, Tempo, of the music composition can enable the automated music performance system of the present invention to automatically switch sample sets that are based on length or agility. Knowledge of Tempo can also help determine note cut-off and secondary note cut-off performances. 
     Each instrument assigned to a Role abstracted from the music composition to be digitally performed becomes an “instrument assignment.” This assignment is then given a mixing algorithm with a set of controllable DSPs (from volume to filters, reverb, etc.). These algorithms are written with the same parameters as the sample selections—but happen on an “instrument assignment” (also known as a “instrument type”) level, not on the specific sample set or instruments. The instrument assignment becomes an audio bus, which allows for any specific instrument, within the assignment constraints, to be swapped out with a similar instrument type. For example, when a grand piano is being used and the user wants to swap it out with an upright piano, that assignment would stay the same—using all the same DSP and mixing algorithms. Finally all these assignments (that have become busses) are assigned to a master mixing bus and are delivered to users as either stems (each buss individually) or a master track. 
       FIG. 28A  describes an exemplary set of Musical Roles or Musical Parts (“Roles”) of each music composition to be automatically analyzed by the automated music performance system of the present invention, prior to automatically generating a digital music performance using the deeply-sampled virtual musical instrument (DS-VMI) libraries maintained in accordance with the principles of the present invention. As shown, musical instruments and associated performances can be assigned any of the exemplary Roles listed in the table of  FIG. 28 . It is understood that others skilled in the art will coin or define other Roles for the purposes of practicing the system and methods of the present invention.

     As described above, these Role Assignment Rules/Principles are illustrative in nature and will vary from illustrative embodiment to illustrative embodiment, when practicing the present invention. 
       FIG. 29  provides a specification for the output file structure of the automated music composition analysis stage, containing all music-theoretic state descriptors (including notes, music metrics and meta-data organized by extracted “Roles”) that might be automatically abstracted/determined from a sheet-type music composition during the preprocessing state of the automated music performance process of the present invention. As shown, the exemplary set of music-theoretic state descriptors include, but are not limited to, Role or Part of Music (e.g. Accent, Back Beat, Background, Big Hit, Color, Constant, High Lane, Low Lane, etc.) to be performed; MIDI Note Value (A1, B2, etc.), Duration of Notes, and Music Metrics including Position of Notes in a Measure, Position of Notes in a Phrase; Position of Notes in a Section, Position of Notes in a Chord, Note Modifiers (Accents),Dynamics, MIDI Note Value Precedence and Antecedence, What Instruments are Playing, Position of Notes from Other Instruments, Relation of Sections to Each Other, Meter and Position of Downbeats and Beats, Tempo Based Rhythms, What Instruments might be assigned to a Role, based on the automated analysis of the music composition and its recognized notation. 
     In some ways, this output data file for the pre-analyzed music composition is an augmented music performance notation file that is Role-organized and timeline indexed and contains all of the music state data required for the automated music performance system of the present invention to make intelligent and contextually-aware instrument and note selections and processing operations in real-time, to digitally perform the music composition in a high-quality, deeply expressive and contextually relevant manner, using the instrument performance logic deployed in the innovative DS-VMI Libraries of the present invention. As described hereinabove, this performance logic will typically be expressed in the form of “If X, then Y” performance rules, driven by the music-theoretic states that are captured and reflected in the structure of the music-theoretic state data descriptor file generated for each music composition to be digitally performed. However, this performance logic may be implemented in other ways which will occur to those with ordinary skill in the art. 
     Using the music-theoretic music composition analysis method of the present invention, each pre-analyzed music composition state descriptor file generated by the process, will embody Role-based note data, music (note) metric data and music-meta data automatically abstracted from the music composition to be digitally performed. Also, each music-theoretic state data descriptor file output from this pre-processor should be capable of driving the automated music performance engine of the present invention, by virtue of the fact that the music-theoretic state descriptor data will logically trigger (and cause to execute) relevant musical instrument performance rules that have been created and assigned to groups of sampled notes/sounds managed in each deeply-sampled virtual musical instrument (DS-VMI) Libraries maintained by the automated music performance system. 
     When the music-theoretic state data descriptor file, functioning as an augmented music performance notation file, is supplied to the Automated Music Performance Engine of the present invention, the Automated Music Performance Engine automatically analyzes and processes the data file for Roles, Notes, Music Metrics, and Meta-Data contained in the music-theoretic state data descriptor file. If the Automated Music Performance Engine determines that certain Music-Theoretic State Data Descriptors are present in the input music composition/performance file (representative of certain music conditions present in the music composition to be digitally performed), then certain Musical Instrument Performance Rules will be automatically triggered and executed to process and handle particular sampled notes, and corresponding Music Instrument Performance Rules will operate on the notes and generate the processed notes required by the input music composition/performance file being processed by the Automated Music Performance Engine, to produce a unique and expressive musical experience, with a sense of realism hitherto unachievable when using conventional machine-driven music performance engines.

     At Block B in  FIG. 31 , the method involves (a) analyzing the key, tempo and duration of the piece, (b) analyzing the form of phrases and sections, (c) executing and shorting chord analysis, and (d) computing music metrics based on the parameters specified in  FIG. 32 , and described hereinabove. 
     As shown at Block C in  FIG. 31 , the method involves abstracting Roles from analyzed music-theoretic state data, and performing the functions specified in this Block, including: (a) Reading Tempo and Key and verify against analyzation (if available); (b) Reading MIDI note values (A1, B2, etc.); (c) Reading duration of notes; (d) Determining the Position of notes in a measure, phrase, section, piece; (e) Evaluating the position of notes in relation to strong vs weak beats; (f) Determining the Relation of notes of precedence and antecedence; (g) Reading CC data (Volume, Breath, Modulation, etc.); (h) Reading program change data; (i) Reading MIDI markers and other text; and (j) Reading the instrument list. 
     As shown at Block D in  FIG. 31 , the method involves parsing note data based on Roles abstracted from the MIDI music composition data file, and sending this data to the output of the music composition analyzer. 
       FIG. 32  provides a specification of all music-theoretic state descriptors generated from the analyzed music composition (including notes, metrics and meta-data) that might be automatically abstracted/determined from a MIDI-type music composition during the preprocessing state of the automated music performance process of the present invention, wherein the exemplary set of music-theoretic state descriptors include, but are not limited to, Role (or Part of Music) to be performed, MIDI Note Value (A1, B2, etc.), Duration of Notes, and Music Metrics including Position of Notes in a Measure, Position of Notes in a Phrase, Position of Notes in a Section, Position of Notes in a Chord, Note Modifiers (Accents), Dynamics, MIDI Note Value Precedence and Antecedence, What Instruments are Playing, Position of Notes from Other Instruments, Relation of Sections to Each Other, Meter and Position of Downbeats and Beats, Tempo Based Rhythms, What Instruments are assigned to a Role (e.g. Accent, Background, etc.).

2. Role-to-Instrument-Type Assignment Rule: This Role may be assigned to be instrument types related to Cymbal.
 
3. Role-to-Instrument-Performance-Logic Assignment Rule: Depending on density of part, and perceived style, the Cymbal Drum set role will be assigned to a specific performance that can determine how to switch all the articulations contained within a Cymbal.

1. Role-to-Note Assignment Rule: This Role may be assigned to clusters of notes that happen at the end of measures, or that are denser, but that are less consistent than Hi-Hat or Cymbal(ride).
 
2. Role-to-Instrument-Type Assignment Rule: This Role may be assigned to Instrument Types related to a Tom Drum Set.
 
3. Role-to-Instrument-Performance-Logic Assignment Rule: This role will be assigned to instrument performances based on density and position in measure that will determine which toms play which pitches and when the pitches switch. (e.g. Tom “low pitch only”, Tom “low tom with low-mid tom accent”)
 
Kick Drum Set Role:
 
1. Role-to-Note Assignment Rule: This Role is assigned often to notes close to or around the strong beats.
 
2. Role-to-Instrument-Type Assignment Rule: The Kick Drum Set Role may be assigned instrument types related to Kick.
 
3. Role-to-Instrument-Performance-Logic Assignment Rule: The Kick Drum set role may be assigned to instrument performances related to Kick. Depending on density of part, and perceived style, this Role will be assigned a specific performance that can determine how to switch all the articulations contained within a Kick.
 
     As described above, these Role Assignment Rules/Principles are illustrative in nature and will vary from illustrative embodiment to illustrative embodiment, when practicing the present invention.

     Method of Sampling, Recording and Cataloging Real Musical Instruments and Producing A Deeply-Sampled Virtual Musical Instrument (DS-VMI) Library Management System for Use in the Automated Music Performance System of the Present Invention 
       FIG. 40  shows a framework for classifying and cataloging a group of real musical instruments, and standardizing how such musical instruments are sampled, named and performed as virtual musical instruments during a digital performance of a piece of composed music. As shown, real and virtual musical instruments are classified by their performance behaviors, and musical instruments with common performance behaviors are classified under the same or common instrument type, thereby allowing like musical instruments to be organized and catalogued in the same class and be readily available for selection and use when the instrumentation and performance of a composed piece of music in being determined. 
       FIG. 41  shows an exemplary catalog of deeply-sampled virtual musical instruments maintained in the deeply-sampled virtual musical instrument library management subsystem of the present invention. In the illustrated embodiment of the present invention, the automated music performance system supports an extremely robust classification that provides a known set of parameters across each of the 100+ Types that allows a performance logic to be applied to chosen samples, given a performance with a musical composition. 
     Specification of Instrument Names, Instrument Types, Instrument Behaviors Classified in the Deeply-Sampled Virtual Musical Instrument DS-VMI Library Management System of the Present Invention 
     Lists of Instruments 
     In  FIGS. 42A through 42J , there is shown an exemplary list of all the instrument contractors in the automated music performance system which will be maintained and updated in the system. These Instruments are grouped by their parent “Type”. 
     List of Instrument Types 
     In the illustrative embodiment, the classifier called “Type” is used to denote how a usable template is created and how the Instrument should be assigned in the automated music performance system, and thus the Instrument should be recorded during the sampling session.  FIGS. 43A  though  43 C show an exemplary list of Instrument “Types” supported by the automated 
     List of Behaviors 
     In  FIGS. 44A through 44E , there is shown an exemplary List of Behaviors supported by the deeply-sampled virtual musical instruments (DS-VMI) supported in the automated music performance system. Typically, a “Behavior” tab will be generated by the automated music performance system, along with a “Behavior/Range” tab. This set of Behaviors will grow with each new instrument Type that gets added into the automated music performance system. As shown in the Drawings, the Type of Behavior called “Downbeat” has two Aspects with Values of “Long” and “Down”. When reading this list, the first element of the Behavior specification, namely “XXXX( ).” is always the Behavior specification, with the Aspects following with their associated Values. 
     Preferably, the system is designed so that by selecting a Type from the Type List will result in the automated generation of a sampling template specifying what Notes to sample on the real instrument (to be sampled) based on its Type, as well as a Note Range that is associated with it. If there is no note range, then it&#39;s not a tonal behavior/aspect, and does not have a “range”. When a user wants to add an instrument into the automated music performance system, the instrument list is referenced to determine if the requested instrument relates to an Instrument Type. However, the Instrument List does not dictate a number of sample attributes, namely: how many round robins, velocities and other granular level sample things that need to be addressed. Often, these decisions are made on the day of the sampling session and is based on time and financial constraints. Also, a file naming structure for sound samples should be developed and used that helps parse out the names to be read by the Type and Instrument Lists. 
     During system operation, the automated music performance system of the present invention automatically (i) classifies each deeply-sampled virtual musical instrument (DS-VMI) entered into its instrument catalog, (ii) informs the system of the type of the instrument and what range of note it performs, (iii) sets a foundation for the automated music performance logic subsystem to be generated for the instrument, enabling automatic selection of appropriate sample articulations that dramatically alter the sound produced from each deeply-sampled virtual musical instrument, based on the music-theoretic states of an input music composition being digitally performed. 
     Specification of the Method of Sampling and Recording Samples from Real Musical Instruments and Other Non-Musical Audio Sources of the Present Invention 
       FIG. 45  illustrates various audio sound sources that can be sampled during a sampling and recording session to produce deeply-sampled virtual musical instrument (DS-VMI) libraries capable of producing “sampled audio sounds” produced from real musical instruments, as well as natural sound sources, including humans and animals. 
       FIG. 46  describes a sampling template for use in organizing and managing any audio sampling and recording session involving the deep-sampling of a specified type of real musical instrument (or other audio sound source) for the purpose of producing a deeply-sampled virtual musical instrument (DS-VMI) library for entry into the DS-VMI library management subsystem of the present invention. As shown, this sampling template includes many information fields for capturing many different kinds of information items, including, for example: real instrument name; instrument type; recording session—place, date, time, and people; information categorizing essential attributes of each note sample to be captured from the real instrument during the sampling session; etc. 
       FIG. 47  graphically illustrates a musical instrument data file, structured using the sampling template of  FIG. 46 , and organizing and managing sample data recorded during an audio sampling and recording session of the present invention involving, for example, the deep-sampling of a specified type of real musical instrument to produce a musical instrument data file for supporting a deeply-sampled virtual musical instrument library, for use during digital performance. 
       FIG. 48  illustrates a definition of a deeply-sampled virtual music instrument (DS-VMI) according to the principles of the present invention. As shown, the definition shows a virtual musical instrument data set containing (i) all data files for the sets of sampled notes performed by a specified type of real musical instrument deeply-sampled during an audio sampling session and mapped to note/velocity/microphone/round-robin descriptors, and (ii) MTS-responsive performance logic (i.e. performance rules) for use with samples in the deeply-sampled virtual musical instrument. 
     Specification of the Music-Theoretic State Responsive Instrument Contracting Logic for the Deeply-Sampled Virtual Musical Instruments of the Present Invention 
       FIG. 49  illustrates the music-theoretic state (MTS) responsive virtual musical instrument contracting/selection logic for automatically selecting a specific deeply-sampled virtual musical instrument to perform in the digital performance of a music composition. Collectively, the Automated Virtual Musical Instrument (VMI) Contractor/Selection Subsystem shown in  FIGS. 2, 9 and 17  and associated VMI Contractor Logic (Rules) shown in  FIG. 49  enable the Automated Music Performance System to automatically select Deeply-Sampled Virtual Musical Instruments (DS-VMIs) to perform in the music performance for the input music composition. Preferably, the VMI contractor logic includes [IF X, then Y] formatted rules that specify the music-theoretic states and conditions that automatically select specific virtual musical instruments from the DS-VMI library management subsystem for digital performance of the music composition. 
     Specification of the Music-Theoretic State (MTS) Responsive Performance Logic for the Deeply-Sampled Virtual Musical Instruments of the Present Invention 
       FIG. 50  illustrates music-theoretic state (MTS) responsive performance logic for controlling specific types of performance of each deeply-sampled virtual musical instrument supported in the deeply-sampled virtual musical instrument (DS-VMI) library management subsystem of the present invention. Also, the Automated DS-VMI Selection and Performance Subsystem in  FIGS. 2, 9 and 17  and associated (Music-Theoretic State Responsive) Performance Logic (Rules) in  FIG. 50  enable the Automated Music Performance System to automatically select samples from automatically-selected (and manually-override-selected) Deeply-Sampled Virtual Musical Instruments (DS-VMIs) and then execute their Performance Logic (i.e. Rules) to process selected samples to generate a music performance that is contextually-relevant to the music theoretic states of the input music composition. 
     These two rule-based subsystems described above and schematically depicted in  FIGS. 49 and 50  provide the automated music performance system with its advanced musical-awareness and music-intelligence functionalities. 
     Classification of Virtual Musical Instruments in the DS-VMS Library Management Subsystem 
       FIG. 51  shows a tree diagram illustrating the classification of deeply-sampled virtual musical instruments (DS-VMI) that are cataloged in the DS-VMI library management subsystem of the present invention. As shown, this classification uses Instrument Definitions based on one or more of the following attributes: Instrument Type, Instrument Behaviors, Aspects (Values), Release Types, Offset Values, Microphone Type, Position and Timbre Tags used during a sampling and recording session, and Instrument Performance Logic (i.e. Performance Rules) specially created for a given DS-VMI given its Instrument Type and Behavior. 
     Method of Sampling, Recording, and Cataloging Real Musical Instruments for Use in Developing Corresponding Deeply-Sampled Virtual Musical Instruments (DS-VMI) for Deployment in the Deeply-Sampled Virtual Musical Instrument (DS-VMI) Library Management System of Present Invention 
       FIG. 52  describes the primary steps in the method of sampling, recording, and cataloging real musical instruments for use in developing corresponding deeply-sampled virtual musical instruments (DS-VMI) for deployment in the deeply-sampled virtual musical instrument (DS-VMI) library management system of present invention. 
     In order to be able to predictively select sampled notes from a deeply-sampled virtual musical instrument library, that plays very well with the music-theoretic states of the music composition being digitally performed, the present invention teaches to sample the real instrument based on its Instrument Type, Behavior and how it is performed. Also, the present invention also teaches to catalogue each sampled note using a naming convention that is expressed in a performance logic (i.e. set of performance rules) created for the Type of the deeply-sampled virtual musical instrument, executed upon the detection of conditions in the music-theoretic state of the music composition that matches the condition expressed in the conditional part of the performance rules. 
     Using this technique, it is possible for the automated music performance system to be provided a degree of artificial intelligence and predictive insight on what sampled notes in the DS-VMI library management subsystem should be selected and processed for assembly and finalization in the digital performance being produced for the music composition provided to the system. 
     As indicated at Step A in  FIG. 52 , the method involves classifying the type of (i) real musical instrument to be sampled, (ii) natural audio sound source, or (iii) synthesized sound source, and adding this type of “instrument” to the deeply-sample virtual musical instrument (DS-VMI) library. Each instrument has to be defined as to the scope of what to record, how to record, and what mixes (or microphones) need to be captured. 
     In general, in accordance with the spirit of the present invention, sampled audio sounds can be synthesized sampled notes, AI produced samples, Sample Modeling, or sampled audio sounds, and therefore, sampled audio can represent (i) a sample note produced by a real (tonal) musical instrument typically tuned to produce tonal sounds or notes (e.g. piano, string instruments, drums, horns, (ii) a sampled sound produced by an atonal sound source (e.g. ocean breeze, thunder, airstream, babbling brook, doors closing, and electronic sound synthesizers, etc.) or (iii) a sampled voice singing or speaking, etc. 
     Also, the term “virtual musical instrument (VMI)” as used throughout the Patent Specification is any virtual musical instrument is made from (i) a library of sampled audio sound files representative of musical notes and/or other sounds, and/or (ii) a library of digitally synthesized sounds representative of musical notes and/or other sounds. When using an audio-sound sampling method, the notes and/or sounds do not have to be sampled and recorded from a real musical instrument (e.g. piano, drums, string instrument, etc.), but may be produced from non-musical instrument audio source, including sources of nature, human voices, animal sounds, etc. When using a digital sound synthesis method, the notes and/or sounds may be digitally designed, created and produced using sound synthesis software tools such as, for example, MOTU&#39;s MACHFIVE and MX4 software tools, and Synclavier® sound synthesis software products, and the notes and sounds produced for these VMI libraries may have any set of sonic characteristics and/or attributes that can be imagined by the sound designer and engineered into a digital file for loading and storage in, and playback from the virtual musical instrument (VMI) library being developed in accordance with the principles of the present invention. 
     When using a digital audio/sound synthesis method to produce the notes and sound files for a particular virtual musical instrument (VMI) library, the users may readily adapt the sampling template, instrument definitions, and cataloging principles used for sound sampling methods disclosed and taught herein for digitally-synthesized virtual musical instruments (DS-VMI) having notes and sounds created using digital sound synthesis methods known in the art. 
     It is appropriate at this junction to describe in greater detail how such tools and devices may be readily adapted and used when producing notes and sounds for VMIs using the digital sound synthesis (DS) method. 
     A synthesis sound module can be defined as a set of synthesis parameters (FM, Spectral, Additive, etc.) that could contain a sound generating oscillator(s) that is assigned a waveform(s), manipulated by amplitude, frequency and filters, with control of each manipulation via other oscillators, generated envelopes, gates, and external controllers. In the VMI sound synthesis space, each designed synthesis module with specified static or ranged parameters can be assigned the same Behavior and Aspect value schema as when developing a deeply-sampled virtual musical instrument (DS-VMI) library. A single digitally-synthesized VMI could contain multiple sound modules to support a robust deep synthesis of a single instrument type. For example, a sound module could be created to mimic the sustain of a violin, a pizzicato of a violin, or a tremolo of a violin, each are separate modules, but could exist as a single VMI so that the role/performance algorithm that is assigned to the violin instrument could use either the sampled version or the synthesis version agnostically. 
     These classifications of these sound modules for digitally synthesized VMIs is done in the same way that a single sound sample would be classified, but instead of a bank of individual note samples, a sound module would provide open handles for data to be submitted, for example: Instrument Definition: Synthesized Harp: 2 Sound modules: Sound Module 1 consists of 2 Oscillators (sine and noise), Sine oscillator has an envelope applied that controls amplitude over time (decay), Noise oscillator has a filter and amplitude envelope applied that has a hard attack and a very fast decay. Second Sound Module has 3 Oscillators, (Sine+0 (semitones), Sine+12 (semitones), Noise). Both sine oscillators have an envelope applied that controls amplitude over time (decay) with the first sine oscillator at −30 db gain and the second at 0 db gain. Noise oscillator has a filter and amplitude envelope applied that has a hard attack and a very fast decay. The instrument definition has open handles for manipulation by the engine: Pitch Selection (oscillator pitch change, based on MIDI note), Velocity Selection (oscillator filter and volume change based on MIDI velocity), and Gate (trigger of note on/off, based on MIDI note start and end times). 
     Each synthesized instrument definition can be cataloged (with the exception of the cataloging of the single sample note recorded audio) against the same template instrument definition as used when developing a deeply-sampled virtual musical instrument (DS-VMI) library. Using the prior example, the Synthesized Harp would fall under the instrument type “Harp” template which states the Behavior is a “single_note” and can change Aspects with the values of “regular” or “harmonic”. The first sound module would be cataloged as the “regular” aspect and the second would be the “harmonic” aspect. If the system had available the Synthesized harp and set a harp performance, the instrument would perform the same way as the sampled harp would, allowing for switching of regular and harmonics, and pitch/velocity controlled data, but instead of playing back samples, the engine would render the synthesized reproduction through the sound modules. 
     Returning now to the operations flow of the system, as indicated at Step B in  FIG. 52 , based on the instrument type, assigning a behavior and note range to the real musical instrument to be sampled. 
     As indicated at Step C in  FIG. 52 , based on behavior and note range, creating a sample instrument template for the real musical instrument to be sampled, indicating what notes to sample on the instrument based on its type, as well as a note range that is associated with the real instrument. 
     As indicated at Step D in  FIG. 52 , using the sample instrument template illustrated in  FIG. 26 , sample the real musical instrument and record all samples (e.g. sampled notes) or sample non-musical sound sources and record all samples (e.g. sampled audio sounds), and assign File Names to each audio sample according to a Naming Structure, as illustrated below: 
     Sound Sampling Process According to the Present Invention: 
     
         
         
           
             a. Each sound sample is categorized by the following:
           i. Recording Session
               1. This is a single data point, just for organization of a set of samples   
               ii. Manual Type/Style
               1. Multiple data can be stored in the form of CamelCase Tokens—this is then entered and read by our cataloging system to inform what the samples are and what they do.   2. This is typically an alternate version of the family of instruments, For example: Different types of Snares, Violin Pizzicato vs Bowed   
               iii. Articulation Type (if percussion)
               1. Often defined as stroke type: Buzz Roll, Rim Shot, Stick on Head, etc. (see glossary)   
               iv. MIDI Note Range (0-127)   v. MIDI Dynamic (or velocity) Range (0-127)   vi. Sample-Hold Trigger Style
               1. Sustain (loops until note-off)   2. One-Shot (plays until Release is finished)   3. Legato (Transitions from one note to the next note)   
               vii. Number in Round Robin Count (see glossary)   viii. Sample Release Type (see glossary)
               1. Short   2. Long   3. Modifier: Performance Release   
               ix. Mix or Specified Microphone Position   
         
           
         
       
    
     As indicated at Step E in  FIG. 52 , the method involves cataloging the deeply-sampled virtual musical instrument, in the DS-VMI library management system, as illustrated below: 
     Cataloging Process: 
     
         
         
           
             b. Instrument File (The physical container for the sample sets) illustrated in  FIG. 27 
           i. This is the Musical Instrument File containing all the data from Sampling Process, what samples were recorded, the mapping of each sample to a note/velocity/microphone/round-robin, etc.   ii. Can contain multiple instruments   iii. Contains the data for all the sample names to be read by the following Instrument Definitions.   
         
             c. Instrument Definition (The Data Set for an instrument illustrated in  FIG. 28 
           i. Constructed from the Instrument File shown in  FIG. 27     ii. Several Instrument Definitions can reference an Instrument File   
         
             d. Behaviors
           i. Behaviors are the types of things an instrument can do—for example “Do I play a single string, or a single note on a keyboard, am I triggering some type of FX or Hit?”   ii. Behaviors are all related/linked to a single Instrument Definition   
         
             e. Aspects
           i. Aspects belong to a single behavior; a single behavior can have many aspects. Example: What direction am I bowing on a string; Am I triggering a type of Stroke; can I alter the timbre of something; is there a duration associated?—these can all be associated to a behavior of “Plays a Note”.   ii. Aspects inform the system whether note value should be read, or if the note value is not part of a specific aspect   iii. Aspects signify the order of where to look for a type of aspect in the sample file name   iv. Aspects signify if there is an articulation in play or not.   
         
             f. Values
           i. These are assigned to a single aspect. For example: Aspect of “Direction” can have values of Up and Down.   ii. These also contain note values ranges (in MIDI standard format)   iii. These assign the file sample name components   
         
             g. Release Types
           i. Does this instrument contain a “performance” release, or just a single, regular type of release (Long or Short).   
         
             h. Offset Values
           i. Offset Values are assigned to an entire manual+ articulation and referenced by the Behavior ID.   ii. Offset Values tell the system to trigger a sample early by {x} number of milliseconds so a sample can trigger in time.
               1. Samples have pre-transients that are part of the sound but often happen before a sound should be on a “downbeat”, For example: moving a stick through the air to strike a drum creates a slight “whoosh” beforehand. The moment the strike hits the drum head, that is where the downbeat should happen, not at the point of the “whoosh”. If the “whoosh” was cut out, then the natural sound of the drum would not sound right and missing all the sonic data before the downbeat.   2. The other advantage to offset values is to “time” samples for playback. Example: Take a short violin bow sample from a section of players. A player may be slightly early to the rest of the group, so the perceived downbeat should be a little after the start of the sample. This allows us to “time” a string of these samples in a row to allow for a consistent playback of sound.   
               
         
             i. Contractor Instruments
           i. Contractor Instruments contain:
               1. The mix position or microphone type   2. Hard-coded digital signal processing (like reverbs, eq),   3. Proper of the instrument associated with the microphone type to be read by users.   4. Timbre and other classification tags   
               
         
             j. Contractor Groups
           i. Contractor Groups are made up of Contractor Instruments (often just one instrument to a group)   ii. Contractor Groups are assigned to bands   iii. Contractor Groups have timbre and other Classification Tags   iv. Contractor Groups are assigned to specific sets of descriptors for availability for our users to select and create/edit their own bands.   
         
             k. Timbre Tagging
           i. Allows for us to catalog each instrument in the system for search and retrieval   
         
             l. Band Assignments
           i. Bands exists in descriptors and are made from Contractor Groups.   
         
             m. Instrument Constraints
           i. A set of constraints defined within a descriptor that prevent users from adding to many of one instrument. For example: 2 or more Kick Drums would not be acceptable for most descriptors.   
         
             n. Orchestration Decisions
           i. Each performance lane gets a priority of when it should play and instrument based on combinations of instruments and activity instructions provided by either the system or the user.   
         
           
         
       
    
     As indicated at Step F in  FIG. 52 , the method involves writing logical contractor rules (i.e. contractor logic) for each virtual musical instrument and groups of virtual musical instruments, for use by the automated music performance system in automatically selecting particular deeply-sampled virtual musical instrument (DS-VMI) libraries, based on the music-theoretic states of the music composition being digitally performed using the principles of the present invention, as follows: 
     Instrument Contractor (i.e. Instrumentation) Logic: 
     
         
         
           
             o. Contractor (i.e. Instrumentation) Logic is a system that establishes what instruments should be chosen under what music-theoretic states in the music composition, and what function these instruments should perform. 
             p. Contractor Logic helps make Bands and allows for the automated music performance system to show awareness of when virtual musical instruments exist in the library system, and when particular virtual musical instruments should be used 
           
         
       
    
     As indicated at Step G in  FIG. 52 , the method involves writing custom performance logic (i.e. rules) for each deeply-sample virtual musical instrument library, following the Instrument Type and Behavior Schema used in designing and deploying the automated music performance system of the present invention. 
     In general, all instruments in the automated music performance system will get a specific type of performance (or logical instructions) written for them, and executable when specific music-theoretic states are detected along the timeline of a music composition being digitally performed. These performances can range from “play a simple hit at {x} velocity” to a “strum a guitar with 6 strings, muting the first two, playing an up stroke on all 6, assembling this position of a chord”. 
     Preferably, each logical performance rule will have an “IF X, THEN Y” format, where X specifies a particular state or condition detected in the music composition and characterized in the music composition meta-data file (i.e. music-theoretic state descriptor data), and Y specifies the specific performance instruction to be performed by the virtual musical instrument on the sampled note selected from a deeply-sampled virtual musical instrument, that has been selected by the logical contractor rules performed by the automated instrument contracting subsystem, employed within the automated music performance system. 
     Below are common examples of music-theoretic states (i.e. music composition meta-data) abstracted from the music composition being digitally performed:
         i. MIDI Note values (A1, B2, etc.),   ii. Durations of notes   iii. Position of Notes in a measure   iv. Position of Notes in a phrase   v. Position of Notes in a section   vi. Position of Notes in a chord   vii. Note Modifiers (accents)   viii. Dynamics   ix. MIDI Note value precedence and antecedence   x. What instruments are available, what instruments are playing and what instruments are playing   xi. Position of Notes from other instruments   xii. Relation of sections to each other   xiii. Meter and position of downbeats and beats   xiv. Tempo based rhythms   xv. What instruments are assigned to a role (play in background, play as a bed, play bass, etc.)   xvi. How many instruments are available?
           1. IE: Drummer has 4 things they can hit, don&#39;t play 5 cymbals, kick and snare at the same time   2. IE: I have a bass, don&#39;t add 2 other basses   
               

     When analyzing and detecting music-theoretic state data (i.e. music composition meta data), the automated music performance subsystem will identify the performance rule associated with the MIDI note values, and determine for what logical performance rule both the music composition state and the performance rule state (i.e. X) matches, and if for performance rule with a match, then the automated music performance system automatically executes the performance rule on the sampled note. Such performance rule execution will typically involve processing the sampled note in some way so that the virtual musical instrument will reasonably perform the sampled note at a specified trigger point, and thereby adapt to the musical notes that are being played around the sampled note. By assigning logical performance rules to certain groups of sampled notes in a (contractor-selected) deeply-sampled virtual musical instrument library, based on instrument type, the automated music performance system is provided with both artificial musical intelligence and contextual awareness, so that it has the capacity to select, process and playback various sampled notes in any given digital performance of the music composition. 
     Values (specially velocity/dynamics) for sampled note processing can be deterministic or random. 
     As indicated at Step H in  FIG. 52 , the method involves predictively selecting sampled notes from each deeply-sampled virtual musical instrument, during the digital music performance of a music composition. Predictive selection of sampled notes in any given deeply-sampled virtual musical instrument library system involves using music-theoretic state data (i.e. music composition meta-data) automatically abstracted from the music composition. Essentially, this music-theoretic state data is used to search and analyze the logical performance rules in the deeply-sampled virtual musical instrument (DS-VMI) library. Setting up this automated mechanism involves some data organization within the deeply-sampled virtual musical instrument (DS-VMI) library management system. 
     For example, each instrument group in the DS-VMI library management system is placed into a family of like instruments called “Types.” This means that each Instrument Type will have exactly the same expected Behavior/Aspect values associated with them.
         xvii. Typically, the DS-VMI library management system will maintain over one hundred different Instrument Types as reflected in FIG.  24 B 1  through  24 B 3 ;   xviii. This provides a framework for standardizing how instruments are sampled, named and performed using the automated music performance system; and   xix. For instance: a shaker will have a Front, a Back and a Double Hit Sample Value associated with it.       

     Many DS-VMI performances will have logical performance rules written for each Type, depending on how an instrument is desired to operate within a given descriptor. Example of the Shaker: Forward, Back and Double, also has 3 velocities associated with it. A soft shake, a sharper “louder” shake, and then a very short, hard “accent” forward shake. These velocities are divided from midi velocity values 1-100, 101-126, and 127-127. One logical performance rule might state: IF the composer sends a series of 8 th  notes, THEN play Forward @ 127, Back at @ 100, Forward @ 110, Back @ 100. Another logical performance rule might state: IF the composer sends a series of 8 th  notes, THEN Play forward, but choose between 101-126 with a 30% chance of playing 127, play back between 90-100, etc. Another logical performance rule might state: IF the composer gives a note on a downbeat, and had a series of notes before it, THEN play a Double @ 127. Note: because the shaker has a lot of sound that precedes it (the pre-transient)—all shakers will be asked to play 250 milliseconds before the actual notes are sent by the composer to “play”—this allows all the shakers to perform in time, without sounding chopped, or late. 
     While the above examples of logical performance rules are rudimentary, they clearly highlight the fact that even the simplest instrument (e.g. shaker) can have multiple instrument performances just given that the instrument has 3 different articulations which it can play. 
     Performance logic created for and used in the DS-VMI libraries of the present invention is not only used for intelligent selection of musical instruments and sampled notes, but also for DSP control involving modifying sampled note selections based on dynamic choice, role assignment, role priority, and other virtual musical instruments available in the library management system. Logical performance rules can be written for executing algorithmic automation and intelligent selection of how to send control to note behavior and sample selection. Logical performance rules can be written to create algorithms that modulate parameters to affect the sound, which may include dynamic blending, filter control, volume level, or a host of other parameters. 
     Matrixing and Using Instrument Types to Create Circular Awareness 
     Allowing instruments to be aware of each other provides some unique and untested waters within performance automation. Consideration might also be given to timing, volume control and iteration and part copy/mutation, as discussed below. 
     Regarding timing, one use case could be if one instrument slows down, what do the other instruments do. If one instrument is assigned a slightly shuffled beat pattern, then can the others respond. 
     Regarding volume control, allowing instruments to self-adjust their overall volume based on other instruments playing around will drastically help in the automation of volume control based on user selectivity and instrument role assignments. 
     Not with regard to specific compositional note assignment, but with regards to how instruments perform, such performance mutation based on other instruments playing types of performances would allow users to select performers and mutate those performers within a given instrument family. Want a mix between Hendrix and Santana? Mutate the performance to select different types of guitar articulations and when to choose various types. 
     Generating a Digital Music Performance of a Music Composition Using the Sampled Notes Selected from the Deeply-Sampled Virtual Musical Instruments Supported by the Automated Music Performance System of the Present Invention 
       FIG. 52  illustrates the primary steps involved in the method of operation of the automated music performance system of the present invention. As shown, the method comprises: (a) using the music composition meta-data abstraction subsystem to automatically parse and analyze each time-unit (i.e. beat/measure) in a music composition to be digitally performed so as to automatically abstract and produce a set of time-line indexed music-theoretic state descriptor data (i.e. music composition meta-data) specifying the music-theoretic states of the music composition including note and composition meta-data; (b) using the automated deeply-sampled virtual musical instrument (DS-VMI) selection and performance subsystem and the automated VMI contracting subsystem, with the set of music-theoretic state descriptor data (i.e. music composition meta-data) and the virtual musical instrument contracting/selection logic (i.e. rules), to automatically select, for each time-unit in the music composition, one or more deeply-sampled virtual musical instruments from the DS-VMI library subsystem to perform the sampled notes of a digital music performance of the music composition; (c) using the automated deeply-sampled virtual musical instrument (DS-VMI) selection and performance subsystem and the set of music-theoretic state descriptor data (i.e. music composition meta-data) to automatically select, for each time-unit in the music composition, sampled notes from deeply-sampled virtual musical instrument libraries for a digital music performance of the music composition; (d) using the automated deeply-sampled virtual musical instrument (DS-VMI) selection and performance subsystem and music-theoretic state responsive performance logic (i.e. rules) in the deeply-sampled virtual musical instrument libraries to process and perform the sampled notes selected for the digital music performance of the music composition; and (e) assembling and finalizing the processed samples selected for the digital performance of the music composition for production, review and evaluation by human listeners. 
     By virtue of this method of the presence invention described above, it is now possible to make better use of deeply-sampled virtual musical instruments used in digital music performances and productions, with increased music performance uniqueness and differentiation. Pre-existing deeply-sampled virtual musical instrument (DS-VMI libraries can be readily transformed into virtual musical instruments with artificial intelligence and awareness of how to perform its sampled notes and sounds in response to the actual music-theoretic states reflected in the music composition being digitally performed. As a result of the present invention, the value and utility of preexisting deeply-sampled virtual musical instrument libraries can be quickly expanded to meet the growing needs in the global marketplace for acoustically rich and contextually-relevant digital performances of music compositions in many diverse applications, while reducing the costs of licensing musical loops required in conventional music performance and production practices. Consequentially, the present invention creates new value in both current and new music performance and production applications. 
     Fourth Illustrative Embodiment of the Automated Music Performance System of the Present Invention, where a Human Composer Composes an Orchestrated “Music Composition” Expressed in a Sheet-Music Format Kind of Music-Theoretic Representation and Wherein the Music Composition is Provided to the Automated Musical Performance System of the Present Invention so that this System can Select Deeply-Sampled Virtual Musical Instruments Supported by the Automated Music Performance System Based on Roles Abstracted During Music Composition Processing, and Digitally Perform the Music Composition Using Automated Selection of Notes from Deeply-Sampled Virtual Musical Instrument Libraries 
     Having described various illustrative embodiments of the automated music performance system of the present invention, it is understood that there will be applications where added functionality will be desired or required, and the system architecture of the present invention is uniquely positioned to support such musical functionalities as will be described below. 
     For example, consider the function of “musical arrangement”, wherein a previously composed work is musically reconceptualized to produce new and different pieces of music, containing elements of the prior music composition. A musical arrangement of a prior music composition may differ from the original work by means of reharmonization, melodic paraphrasing, orchestration, or development of the formal structure. Sometimes, musical arrangement of a musical composition involves a reworking of a piece of music so that it can be played by a different instrument or different combination of instruments, based on the original music composition. However imagined, musical arrangement is an important function when composing and producing music. 
     Also, consider the function of “musical instrument performance style” used when performing a particular musical instrument. Often, the technique employed in practicing a particular musical instrument performance style will significantly change the musical performance by the instrument playing the same group of notes, and therefore is also considered an important function when composing and producing music. 
     Therefore, another object of the present invention is to provide a fourth illustrative embodiment automated music performance system and method of the present invention that supports (i) Automated Musical (Re)Arrangement and (ii) Musical Instrument Performance Style Transformation of a music composition to be digitally performed by the automated music performance system. 
     As will be described in great technical detail below, these two creative musical functions described above can be implemented in the automated music performance system of the present invention as follows: (i) selecting Musical Arrangement Descriptors and Musical Instrument Performance Style Descriptors described in  FIGS. 57 and 58 , from a GUI-based system user interface supported by the system; (ii) providing the user-selected Musical Arrangement Descriptors and Musical Instrument Performance Style Descriptors to the system user interface, as shown in  FIG. 56 ; (iii) then remapping/editing the Musical Roles abstracted from the given music composition as illustrated in  FIGS. 64 and 65 ; and (iv) during automated performance, selecting Musical Instrument Performance Logic supported in the DS-VMI Libraries, that is indexed/tagged with the Music Instrument Performance Style Descriptors selected by the system user, as illustrated in  FIG. 66 , so as to support the automated music performance process illustrated in  FIGS. 67 and 68  and achieve the musical arrangement and music performance style selected/requested by the system user. 
     These additional features of the present invention will be described in greater detail hereinbelow in the context of the automated music performance system of the fourth illustrative embodiment shown in  FIGS. 54 through 68 . 
       FIG. 54  shows the automated music performance system of the fourth illustrative embodiment of the present invention. As shown, the system comprises: (i) a system user interface subsystem for a system user using a web-enabled computer system provided with music composition and notation software programs to produce a music composition in any format (e.g. sheet music format, MIDI music format, music recording, etc.); and (ii) an automated music performance engine (AMPE) subsystem interfaced with the system user interface subsystem, for producing a digital performance based on the music composition, wherein the system user interface subsystem transfers a music composition to the automated music performance engine subsystem. 
     As shown in  FIG. 54 , the automated music performance engine subsystem includes: (i) an automated music-theoretic state (MTS) data abstraction subsystem for automatically abstracting all music-theoretic states contained in the music composition and producing a set of music-theoretic state descriptors data (i.e. music composition meta-data) representative thereof; (ii) a deeply-sampled virtual musical instrument (DS-VMI) library management subsystem for managing the sample libraries supporting the deeply-sampled virtual musical instruments to be selected for performance of notes specified in the music composition; and (iii) an automated deeply-sampled virtual musical instrument (DS-VMI) selection and performance subsystem for selecting deeply-sampled virtual musical instruments in the DS-VMI library management subsystem and processing the sampled notes selected from selected deeply-sampled virtual musical instruments using music-theoretic state (MTS) responsive performance rules (i.e. logic), to automatically produce the sampled notes selected for a digital performance of the music composition, and wherein the automated music performance engine (AMPE) subsystem transfers the digital performance to the system user interface subsystem for production, review and evaluation. 
       FIG. 54A  shows the subsystem architecture of the Automated Deeply-Sampled Virtual Musical Instrument (DS-VMI) Selection and Performance Subsystem employed in the Automated Music Performance (and Production) System of the present invention. As shown, this subsystem architecture comprises: a Pitch Octave Generation Subsystem, an Instrumentation Subsystem, an Instrument Selector Subsystem, a Digital Audio Retriever Subsystem, a Digital Audio Sample Organizer Subsystem, a Piece Consolidator Subsystem, a Piece Format Translator Subsystem, the Piece Deliver Subsystem, a Feedback Subsystem, and a Music Editability Subsystem, interfaced as shown with the other subsystems (e.g. an Automated Music-Theoretic State Data (i.e. Music Composition Meta-Data) Abstraction Subsystem, a Deeply-Sampled Virtual Musical Instrument (DS-VMI) Library Management Subsystem, and an Automated Virtual Musical Instrument Contracting Subsystem) deployed within the Automated Music Performance System of the present invention. The functions of these subsystems are described in great detail in Applicant&#39;s U.S. Pat. No. 9,721,551, incorporated herein by reference in its entirety. 
     The Role Assignment Rules shown and described herein in great detail for the first, second and third illustrative embodiments of the present invention also can be used to practice the automated music performance system of the fourth illustrative embodiment of the present invention, and carry out each of its stages of data processing described hereinabove. 
       FIG. 55  shows the system of the  FIG. 54  implemented as enterprise-level internet-based music composition, performance and generation system, supported by a data processing center with web servers, application servers and database (RDBMS) servers operably connected to the infrastructure of the Internet, and accessible by client machines, social network servers, and web-based communication servers, and allowing anyone with a web-based browser to access automated music composition, performance and generation services on websites to score videos, images, slide-shows, podcasts, and other events with music using deeply-sampled virtual musical instrument (DS-VMI) synthesis methods of the present invention as disclosed and taught herein. 
       FIG. 56  shows an exemplary wire-frame-type graphical user interface (GUI) screen based system user interface of the automated music performance system of the fourth illustrative embodiment. As shown, this GUI screen indicates and instructs the system user on how to transform the musical arrangement and musical instrument performance style of a music composition before the automated digital performance of the music composition. As shown, the GUI-based system user interface modeled in  FIGS. 54 through 55  invites a system user to select (via menus) (i) an Automated Musical (Re)Arrangement, and/or (ii) Musical Instrument Performance Style Transformation of the music composition to be digitally performed by the system, through a simple end-user process involving: (i) selecting Musical Arrangement Descriptors and Musical Instrument Performance Style Descriptors from a GUI-bases system user interface; and (ii) then providing the user-selected Musical Arrangement Descriptors and Musical Instrument Performance Style Descriptors to the automated music performance system; whereupon (iii) the Musical Roles abstracted from the given music composition are automatically remapped/edited to achieve the selected musical arrangement; and (iv) the Musical Instrument Performance Logic supported in the DS-VMI Libraries, and indexed/tagged with the Music Instrument Performance Style Descriptors selected by the system user, are automatically selected for modification of sampled notes during the automated digital performance process. 
       FIG. 57  shows an exemplary generic customizable list of musical arrangement descriptors supported by the automated music performance system of the fourth illustrative embodiment. Each of these generic musical arrangement descriptors can be customized to a particular musical arrangement conceived by the system engineers/designers, and identified by linguistic (or graphical-icon) descriptors which will be culturally relevant to the intended system users. Also, appropriate programming will be carried out to ensure that proper Role remapping and editing will take place in an automated manner when the corresponding musical arrangement descriptor is selected by the system user. 
       FIG. 58  shows an exemplary generic customizable list of musical instrument performance style descriptors supported by the automated music performance system of the fourth illustrative embodiment. Each of these generic musical instrument performance style descriptors can be customized to a particular musical arrangement conceived by the system engineers/designers, and identified by linguistic (or graphical-icon) descriptors which will be culturally relevant to the intended system users. Also, appropriate programming will be carried out to ensure that proper Musical Instrument Performance Logic (Rules) are indexed or tagged with the corresponding Musical Instrument Performance Style Descriptor in the DS-VMI Libraries, for automated selection and use when the corresponding musical instrument performance style descriptor is selected by the system user. It is understood that the function and each of its performance style descriptors can be globally defined to cover and control the instrument performance style of many different instrument types so that by a single parameter selection on this musical function, the system will automate the instrument style performance for dozens if not hundreds of different virtual musical instruments maintained in the DS-VMI library management subsystem of the present invention. For example, in the event that “Calypso” is defined as a Musical Instrument Performance Style Descriptor, to reflect the Afro-Caribbean music originated in Trinidad and Tobago, then this Musical Instrument Performance Style Descriptor will be used to tag/index each written Musical Instrument Performance Rule (i.e. Performance Logic) installed in the DS-VMI Libraries of the system, and activated in the DS-VMI library management subsystem when selected by the system user, to ensure that the automated music performance system will automatically consider and possibly use this Performance Rule during the automated music performance process if and when the contextual conditions abstracted from the music composition are satisfied. This will ensure that all virtual music instrument performances sound as if they were being played performers following the traditions and musical style of Calypso music. 
       FIG. 59  illustrates the process of automated selection of sampled notes in deeply-sampled virtual musical instrument (DS-VMI) libraries to produce the notes for the digital performance of a composed piece of music in accordance with the principles of the present invention. As shown, this process comprises the following steps: (a) the parsing and analyzing the music composition to abstract music-theoretic state descriptor data (i.e. music composition meta data); (b) transforming the music-theoretic state descriptor data to transform the musical arrangement of the music composition, and modifying performance logic in DS-VMI libraries to transform performance style; (c) using music-theoretic state descriptor data and automated virtual musical instrument contracting subsystem to select deeply-sampled virtual musical instruments (DS-VMI) for the performance of the music composition; (d) using music-theoretic state descriptor data to select notes and/or sounds from selected deeply-sampled virtual musical instrument (DS-VMI) libraries; (e) processing sampled noted using music-theoretic state (MTS) responsive performance logic maintained in the DS-VMI library management subsystem so as to produce processed note samples for the digital performance; and (f) assembling and finalizing the notes in the digital performance of the music composition, for final production and review. 
       FIG. 60  describes a method of automated selection and performance of notes in deeply-sampled virtual instrument (DS-VMI) libraries to generate a digital performance of a composed piece of music. As shown, the system comprises the steps of: (a) capturing or producing a digital representation of a music composition to be orchestrated and arranged for a digital performance using a set of deeply-sampled virtual musical instruments performed using music-theoretic state performance logic (i.e. rules) constructed and assigned to each deeply-sampled virtual musical instrument (DS-VMI); (b) determining (i.e. abstracting) the music-theoretic states of music in the music composition along its timeline, and producing a set of timeline-indexed music-theoretic state descriptor data (i.e. roles, notes, metrics and meta-data) for use in the automated music performance system; (c) based on the roles abstracted from the music composition, selecting deeply-sampled virtual musical instruments available for digital performance of the music composition in a deeply-sampled virtual musical instrument (DS-VMI) library management system; (d) for each note or group of notes associated with an assigned role in the music composition, using the automatically-abstracted music-theoretic-state descriptors (i.e. notes, metrics and meta-data) to select sampled notes from the types of virtual musical instruments selected in the DS-VMI library maintained in the automated music performance system, and using the performance rules indexed with selected musical instrument performance style descriptors to process selected sampled notes to generate notes for a digital performance of the music composition; (e) assembling and finalizing the processed sampled notes in the digital performance of the music composition; and (f) producing the performed notes in the digital performance of the music composition, for review and evaluation by human listeners. 
       FIG. 61  describes the primary steps performed during the method of operation of the automated music performance system of the fourth illustrative embodiment of the present invention shown in  FIGS. 53 through 58 . As described in  FIG. 61 , the music-theoretic state descriptors are transformed after automated abstraction from a music composition to be digitally performed, and the musical instrument performance style rules are modified after the data abstraction process, so as to achieve a desired musical arrangement and performance style in the digital performance of the music composition as reflected by musical arrangement and musical instrument performance style descriptors selected by the system user and provided as input to the system user interface. 
     As shown in  FIG. 61 , the method comprises the steps of: (a) providing a music composition (e.g. musical score format, midi music format, music recording, etc.) to the system user interface; (b) providing musical arrangement and musical instrument performance style descriptors to the system user interface; (c) using the musical arrangement and performance style descriptors to automatically process the music composition and abstract and generate a set of music-theoretic state descriptor data (i.e. roles, notes, music metrics, meta-data, etc.); (d) transforming the music-theoretic state descriptor data set for the analyzed music composition to achieve the musical arrangement of the digital performance thereof, and identifying the performance logic in the DS-VMI libraries indexed with selected musical instrument performance style descriptors to transform the performance style of selected virtual musical instruments; and (e) providing the transformed set of music-theoretic state data descriptors to the automated music performance system to realize the requested musical arrangement, and select the instrument performance logic (i.e. performance rules) maintained in the DS-VMI libraries to produce notes in the selected performance style. 
       FIG. 62  describes the high-level steps performed in a method of automated music arrangement and musical instrument performance style transformation supported within the automated music performance system of the fourth illustrative embodiment of the present invention, wherein an automated music arrangement function is enabled within the automated music performance system by remapping and editing of roles, notes, music metrics and meta-data automatically abstracted and collected during music composition analysis, and an automated musical instrument performance style transformation function is enabled by selecting instrument performance logic provided for groups of note and instruments in the deeply-sampled virtual musical instrument (DS-VMI) libraries of the automated music performance system, that are indexed with the musical instrument performance style descriptors selected by the system user. 
       FIG. 63  specifies an exemplary set of Musical Roles (“Roles”) or musical parts of each music composition to be automatically analyzed and abstracted (i.e. identified) by the automated music performance system of the fourth-illustrative embodiment. These roles have been described in detail hereinabove with respect to  FIGS. 28A, 33A, and 38A . 
       FIG. 64  provides a technical specification for a transformed music-theoretic state descriptor data file generated from the analyzed music composition, including notes, metrics and meta-data automatically abstracted/determined from a music composition and then transformed during the preprocessing state of the automated music performance process of the present invention, wherein the exemplary set of transformed music-theoretic state descriptors include, but are not limited to, Role (or Part of Music) to be performed, MIDI Note Value (A1, B2, etc.), Duration of Notes, and Music Metrics including Position of Notes in a Measure, Position of Notes in a Phrase, Position of Notes in a Section, Position of Notes in a Chord, Note Modifiers (Accents), Dynamics, MIDI Note Value Precedence and Antecedence, What Instruments are Playing, Position of Notes from Other Instruments, Relation of Sections to Each Other, Meter and Position of Downbeats and Beats, Tempo Based Rhythms, What Instruments are assigned to a Role (e.g. Accent, Background, etc.). 
       FIG. 65  illustrates how a set of Roles and associated Groups of Note Data automatically abstracted from a music composition are transformed (e.g. remapped and/or edited) in response to the Musical Arrangement Descriptor selected by a system user from the GUI-based system user interface of  FIG. 56 . As shown, different Groups of Note Data are reorganized under different Roles depending on the Musical Arrangement Descriptor selected by the system user. While there are various ways to effect musical arrangement of a music composition, this method illustrated in  FIG. 65  operates by remapping and/or editing the Roles assigned to Groups of Notes identified in the music composition during the automated music composition stage of the automated music performance process of the present invention. It is understood, however, that the musical arrangement function supported within the automated music performance system of the present invention can also involve editing any of the music-theoretic state descriptors (e.g. Roles, Notes, metrics and meta-data) abstracted from a music composition to create a different yet principled musical re-arrangement of a music composition so that the resulting musical arrangement of a prior music composition differs from the original work by means of reharmonization, melodic paraphrasing, orchestration, and/or development of the formal structure, in accordance with principles well known in the musical arrangement art. 
       FIG. 66  shows a deeply-sampled virtual musical instrument (DS-VMI) library that has been provided with music instrument performance logic (e.g. performance logic rules) that haves been indexed/tagged with one or more music performance style descriptors listed in  FIG. 58  in accordance with the principles of the present invention, so that such performance logic rules will be responsive and active to the music performance style descriptor selected by the system user and provided to the system user interface prior to each automated music performance process supported on the system. 
       FIG. 67  illustrates a method of operating the automated music performance system of the fourth illustrative embodiment of the present invention. As shown, the system supporting automated musical arrangement and performance style transformation functions selected by the system user. 
     As indicated at Block A in  FIG. 67 , the system is provided with a music composition for music-theoretic state data abstraction to result in the collection of note, metric and meta data at Block B, involving determining the key, tempo and duration of the music piece; analyzing the music form of the phrases and sections to obtain note metrics; and executing and storing chord analysis and other data evaluations described in  FIG. 68 . 
     As indicated at Block B in  FIG. 67 , the system executes an automated Role Analysis Method based on the music composition data and other data abstracted at Block B. 
     As shown at Block C, the Role Analysis Method involves performing the following data processing operations: (a) determining the Position of notes in a measure, phrase, section, piece; (b) determining the Relation of notes of precedence and antecedence; (c) assigning MIDI note values (A1, B2, etc.); (d) reading the duration of notes; (e) evaluating position of notes in relation to strong vs weak beats; (f) reading historical standard notation practices for possible articulation usages; (g) reading historical standard notation practices for dynamics (via automation); and (h) determining the position of notes in a chord for optionally determining voice-part extraction. 
     As indicated at Block D in  FIG. 68 , the system uses Music Arrangement and Musical Instrument Performance Style Descriptors provided to the system user interface to automatically transform the music-theoretic state data set abstracted from the music composition, and generate transformed roles for use in the automated music performance process. 
     As indicated at Block E in  FIG. 68 , the system uses the transformed Role send data to the composition note parser and group the Note data with the assigned Roles. 
     As indicated at Block F in  FIG. 68 , the system assigns Instrument Types to the transformed Roles and associated (Note) Performances. 
     As indicated at Block Gin  FIG. 68 , the system generates automation data from the analysis. 
     As indicated at Block H in  FIG. 68 , the system generates Note data for each Instrument Type. 
     As indicated at Block I in  FIG. 68 , the system assigns to Instrument Types, virtual musical instruments (VMI) supported in the DS-VMI Library Management Subsystem. 
     As indicated at Block J in  FIG. 68 , the system generates a mix definition for audio track production of the final digital performance of the music composition. The final digital performance will be musically (re)arranged and express the music instrument performance of the musical arrangement and performance style descriptors supplied to the system by the system user. 
     At any time, the system user can return to the system user interface shown in  FIG. 56  and select different musical arrangement and/or performance style descriptors supported in the system menu and regenerate a new digital music performance of the music composition using the DS-VMI Libraries maintained in the system. 
     By virtue of the present invention, automated music (re)arranging and performance style transform functionalities are now available to the automated music performance system of the present invention, along with other custom modes, wherein the music-theoretic state data—automatically abstracted and collected from any music composition—is automatically transformed in a specified manner to generate a suitable and different musical-theoretic state descriptor file that is then used (as system input) by the automated music performance system of the present invention. 
     The advantage of such functionalities will be to enable others to (i) provide a musical composition as system input (via an API, sheet music, audio, MIDI or any other file), and (ii) then make a few simple selections from an arrangement/style menu or have these and/or any selections be made automatically by the system, to then automatically generate new kinds of digital music performances having different instrument arrangements and performed according to different performance styles. 
     In a regular or normal mode of operation, abstracted and collected music theoretic state data parameters (e.g. Roles, Notes, Metrics and Meta-Data) will be transmitted to the automated music performance system without modification or transformation. However, in other alternative musical arrangement/style-transformation modes supported by the system, the abstracted music-theoretic state data parameters (including the Roles, Notes, Metrics and Meta-Data) will be transformed to change the musical instrumental arrangement (in one way or another) and/or performance style thereof in an automated and creative manner to meet the creative desires of users around the world. 
     The innovative functionalities and technological advancements enabled by the present invention promise to create enormous new value in the market allowing billions of ordinary users with minimal music experience or education to automatically rearrange millions of music compositions (and music recordings) to perform, create and deliver new musical experiences by the users selecting (from a menu) or having the system automatically create and/or select system input parameters under descriptors such as: Music Performance Arrangement Descriptors; Music Instrument Performance Style Descriptors; to name just a few. 
     Employing the Automated Music Performance Engine Subsystem of the Present Invention in Other Applications 
     The Automated Music Performance Engine of the present invention will have use in many application beyond those described this invention disclosure. 
     For example, consider the use case where the system is used to provide indefinitely lasting music or hold music (i.e. streaming music). In this application, the system will be used to create unique music of definite or indefinite length. The system can be configured to convey a set of musical experiences and styles and can react to real-time audio, visual, or textual inputs to modify the music and, by changing the music, work to bring the audio, visual, or textual inputs in line with the desired programmed musical experiences and styles. For example, the system might be used in Hold Music to calm a customer, in a retail store to induce feelings of urgency and need (to further drive sales), or in contextual advertising to better align the music of the advertising with each individual consumer of the content. 
     Another use case would be where the system is used to provide live scored music in virtual reality or other social environments, real or imaginary. Here, the system can be configured to convey a set of musical experiences and styles and can react to real-time audio, visual, or textual inputs. In this manner, the system will be able to “live score” content experiences that do well with a certain level of flexibility in the experience constraints. For example, in a video game, where there are often many different manners in which to play the game and courses by which to advance, the system would be able to accurately create music for the game as it is played, instead of (the traditional method of) relying on pre-created music that loops until certain trigger points are met. The system would also serve well in virtual reality and mixed reality simulations and experiences. 
     Modifications of the Illustrative Embodiments of the Present Invention 
     The present invention has been described in great detail with reference to the above illustrative embodiments. It is understood, however, that numerous modifications will readily occur to those with ordinary skill in the art having had the benefit of reading the present invention disclosure. 
     As described in great detail herein, the automatic music performance and production system of the present invention supports the input of conventionally-notated musical information of music compositions of any length or complexity, containing musical events such as, for example, notes, chords, pitch, melodies, rhythm, tempo and other qualifies of music. However, it is understood that the system can also be readily adapted to support non-conventionally notated musical information, based on conventions and standards that may be developed in the future, but can be used as a source of musical information input to the automated music performance and production system of the present invention. Understandably, such alternative embodiments will involve developing music composition processing algorithms that can process, handle and interpret the musical information, including notes and states expressed along the timeline of the music composition 
     While the automated music performance and generation system of the present invention has been disclosed for use in automatically generating digital music performances for music compositions that have been completed, and represented in either music score format or MIDI-music format, it is understood that the automated music performance system of the present invention can be readily adapted to digitally perform music being composed in a “live” or “on-the-fly” manner for the enjoyment of others, using the deeply-sampled virtual musical instruments (DS-VMI) selected from the DS-VMI library management subsystem of the system. In such alternative embodiments, music being composed is either digitally represented in small time-blocks of music score (i.e. sheet music) representation as illustrated in  FIG. 29  or MIDI-music representation as illustrated in  FIG. 30 . Using such methods, small pieces of music-theoretic state data can be automatically abstracted for small time pieces of music being composed by human and/or machine sources, and such streams of music-theoretic state data can be provided to the automated music performance system for automated processing in accordance with the principles disclosed here, to digitally perform the live piece of music as it is being composed “on the fly.” Such alternative embodiments of the present invention are fully embraced by the systems and models disclosed herein and fall within the scope and spirit of the present invention. 
     Also, in alternative embodiments of the present invention described hereinabove, the automated music performance and production system can be realized a stand-alone appliance, instrument, embedded system, enterprise-level system, distributed system, as well as an application embedded within a social communication network, email communication network, SMS messaging network, telecommunication system, and the like. Such alternative system configurations will depend on particular end-user applications and target markets for products and services using the principles and technologies of the present invention. 
     Alternate Methods of Sound Sample Representation and Sound Sample Synthesis when Developing Virtual Musical Instrument (VMI) Libraries According to Principles of the Present Invention 
     As disclosed herein, when using the sound/audio sampling method to produce notes and sounds for a virtual musical instrument (VMI) library system according to the present invention, storage of each audio sample in the .wav audio file format is just one form of storing a digital representation of each audio samples within the automated music performance system of the present invention, whether representing a musical note or an audible sound event. The system described in the present invention should not be limited to sampled audio in .wav format, and should include other forms of audio file format including, but not limited to, the three major groups of audio file formats, namely:
         Uncompressed audio formats, such as WAV, AIFF, AU or raw header-less PCM;   Formats with lossless compression such as FLAC, Monkey&#39;s Audio (.ape), WavPak (.wv), TTA, ATRAC advanced lossless, ALAC (.mpa), MPEG-4 SLS, MPEG-4 ALA, MPEG-4 DST, Windows Media Audio Lossless (WMA lossless), and Shorten (SNH)   Formats with lossy compression, such as Opus, MPO3, Vorbis, Musepak, AAC, ATRAC, Windows Media Audio Lossy (WMA Lossy).       

     Also, when practicing a digital sound/audio synthesis method to synthesize notes and sounds for a virtual musical instrument (VMI) library system according to the present invention, MOTU&#39;s MACHFIVE and/or MX4 software tools, and Synclavier® software tools, are just a few software tools for producing a digital representation of each synthesized audio sample within the automated music performance system of the present invention. Other software tools can be used to create or synthesize digital sounds representative of notes and sounds of various natures. 
     The cataloging of Behaviors and Aspect values can also be applied to other forms of audio replication/synthesis specifically with regards to Role and Instrument Performance Assignment. For example, a synthesis module can be provided within the automated music performance engine, to support various controls to Attack and Release that could mimic the same kinds of Behaviors that a violin can perform. These Instrument Performance settings can be stored and sent to the synthesis module for the purpose of mimicking the same instrument type template as violin, and assigned to this instrument type for use within the automated music performance system. 
     These and all other such modifications and variations are deemed to be within the scope and spirit of the present invention as defined by the accompanying Claims to Invention. 
     Modifications to the Present Invention which Readily Come to Mind 
     The illustrative embodiments disclose the use of a novel method of developing and deploying deeply-sampled virtual musical instruments (DS-VMIs) provided with performance logic rules based on the behavior of its real corresponding musical instrument designed to predict and control the performance of the deeply-sampled virtual musical instrument in response to real-time detection of the music-theoretic states including notes of the music composition to be digitally performed using the deeply-sampled virtual musical instruments. Using this novel virtual musical instrument (VMI) design, it is now possible for libraries of deeply-sampled virtual musical instruments to produce more expressive, more intelligent and richer performances when driven by any source of composed music, however composed. However, it is understood that alternative products and technologies may be used to practice the various methods and apparatus of the present invention disclosed herein. For example, machine learning may be used within the automated music performance system to support deterministic or stochastic based music performances. The use of machine learning would analyze music compositions to abstract music-theoretic state data on each input music composition. Machine learning (ML) may also be used to analyze digital performances, either currently existing in the system, or through a training against real-world performances, through sample matching and recognition against audio. Then, with this analyzation, the automated music composition would come up with predictive models on how the automated music performance system would choose the modifications to sampled notes from a particular instrument, when the modification are placement specific (i.e. are called for by the logical performance rules). 
     These and other variations and modifications will come to mind in view of the present invention disclosure. While several modifications to the illustrative embodiments have been described above, it is understood that various other modifications to the illustrative embodiment of the present invention will readily occur to persons with ordinary skill in the art. All such modifications and variations are deemed to be within the scope and spirit of the present invention as defined by the accompanying Claims to Invention.
