## Background
CROSS REFERENCES TO RELATED APPLICATIONS
This application claims priority from U.S. Provisional Patent Application Ser. No. 61/609,196, entitled “Portable Piano Keyboard Computer”, filed on Mar. 9, 2012, which is hereby incorporated by reference as if set forth in full in this application for all purposes.


BACKGROUND
Today's electronic musical devices are often provided with many ways to interconnect to other devices. Simpler devices such as instruments may only have a single signal output such as an electric guitar which uses a standard 1⁄4 inch plug connector to provide an analog musical signal generated by the guitar. Other advanced electric guitars or other instruments may provide additional types of signals having associated connectors such as Musical Instrument Digital Interface (MIDI), Universal Synchronous Bus (USB), XLR connector by Canon, Deutsches Institut für Normung (DIN) connector, etc.
Each of these various signal and/or connector standards has its own properties and each may differ in its ability to convey information in both the type of information and amount. Generally, the signal/connector types are not compatible with each other, yet many signal/connector types may need to be accommodated in certain musical devices.
For example, a mixing board, electronic keyboard, electronic instrument, computer, analog to digital converter, music-adapted computing system, etc., all interconnected into a system, such as a recording system, may require dozens or even hundreds of connectors of several or many different types. Usually because of design constraints, many of the connectors are located along the sides or back of the enclosures of the musical devices. While such a layout is desirable to keep the many cables and wires out of the way of the control and display surfaces, the inability to easily view and obtain information about a connector's current status or operation can cause problems or inefficiencies for a user of the musical devices or system.

BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 illustrates an exemplary musical device that may be used with features described herein;
FIG. 2 shows a rear-view of the musical device of FIG. 1, including connectors;
FIG. 3 shows an example arrangement of musical devices in a recording studio setup; and
FIG. 4 shows basic components of an input/output visualizer.



DETAILED DESCRIPTION OF EMBODIMENTS
FIG. 1 illustrates an exemplary musical device such as that described generally in the provisional patent application referenced, above. In FIG. 1, portable piano keyboard 100 includes display screen 110 including touch sensors, piano keys 120, touchpad and associated buttons 130. Although specific user input/output controls are shown it should be apparent that many variations of musical devices are possible including other types of user input devices or controls such as an alphanumeric keyboard, mouse, trackpad; buttons, knobs, sliders and other discrete controls, etc. Other types of output are possible such as audio, discrete lights or indicators, etc. In general, a musical device can be any device that is used in a music application.
Connectors such as 150, 152, 154 and 156 are shown along the left side of the musical device at 140. Connectors are many and varied and can be of any type used in a musical device to send and/or receive signals to or from another musical device. For example, in FIG. 1, connector 150 is a socket to supply power to musical device 100. Typically, the plug for connector 150 would be a power adapter but in some cases the plug may originate from another musical device such as a mixing board, power management system, etc., that can be used to provide power to musical device 100. Connectors 152 and 154 are Universal Serial Bus (USB) connectors that can be used to connect instruments, peripherals or other musical devices. USB connectors provide a way to exchange high-speed digital signals among musical devices. Connector 156 is a standard audio output jack for outputting an analog signal to be heard by a user such as through headphones or speakers. In general, any type of plug, socket, jack or other means of connecting or coupling two devices together is included in the term “connector” including wireless means of communication such as Wi-Fi, Bluetooth, Ethernet, MIDI, etc.
FIG. 2 shows a rear-view of the musical device of FIG. 1. In FIG. 2, the back 210 of display screen 110 of FIG. 2 is shown overhanging connectors at 200 which are along the back of the musical device. Connectors 212-220 are symbolic depictions of any types of connectors, including, for example, those listed in Table I, below.

It should be apparent from FIGS. 1 and 2 that connectors such as at 140 and 200 can be difficult or impossible to view from a user's point of view during normal operation of the musical device. In cases such as the connectors along the rear of the musical device at 200 it is not even possible to see whether a cable has been attached to the connector. Often there are many cables that can be connected to other devices that may be too far away to see so that even if it is known that a cable is connected to a connector it is difficult or impossible to know visually the type of device that is connected and the types of signals being exchanged.
FIG. 3 shows an example arrangement of musical devices in a recording studio setup. In FIG. 3, recording system 300 includes many types of musical devices such as computer software 310 and computer hardware 320. Computer hardware 320 can include MIDI interface 322. Typically the computer software and hardware would be included in a single device such as a personal computer. Although discrete devices are shown having dedicated functionality, it is possible that the functionality can be spread or shared among multiple devices. For example, many musical devices may include a processor and other computing hardware and thus function as computer systems with some or all of their own local resources such as input/output devices, storage systems, software, etc. FIG. 3 is but one basic example of a system. The number and type of musical devices, connections and other properties of this example can vary.
Midi Interface 322 includes connections such as MIDI In/Out connections. For example, Synthesizer/Sampler 330 can be connected to computer hardware by MIDI Interface 322 or by other means. Drum machine 332 is controlled by an optional expander module 334 via synthesizer/sampler 330. Digital deck can be an external storage device such as a digital tape, solid state memory, etc. Many of the musical devices shown in FIG. 3 are connected to audio mixer 336. Note that the devices shown may be analog or digital or both even though they may be indicated as one or the other in the diagram.
Musical instruments such as guitar 352 and bass guitar 354 can be connected to other devices via a line adapter such as line adapter 342 or directly as in the case of bass guitar 354 which is directly connected to audio mixer 336. Microphone 356 is also connected to audio mixer 336 and the connection can be direct if the audio mixer is provided with a microphone connector, or indirect via additional musical devices such as a microphone amplifier, etc. Mastering deck 344 can receive audio or digital signals from audio mixer 336. Although some musical devices might be shown as only sending or only receiving signals, other types of such devices may provide two-way communications. For example, a standard electric guitar may just provide an analog instrument signal output. However, more advanced guitars such as a MIDI controller guitar, self-tuning guitar, etc., can provide additional output signals and can accept various input signals for controlling or sensing conditions or parameters in, on, or relating to the guitar or other instrument or device. Audio mixer 336 also provides an audio output to headphones 360.
As is known in the art, a recording studio or system may be configured in many different ways, with different types of cables and connectors (including wireless) to interconnect the various devices. For example, the musical device of FIG. 1 might be used for one or more of the functions performed by the computer software 310 and hardware 320 of FIG. 3. Or the musical device of FIG. 1 might be used as an input device such as an instrument or microphone at 350, or as synthesizer/sampler 330, etc. In any of these configurations and arrangements of devices it may be difficult to keep track of the many interconnections and to know what is going on in the system concerning the various musical devices.
FIG. 4 shows basic components of an input/output visualizer. In FIG. 4, connectors 409-414 at 400 represent physical connectors and/or signals 212-220 at 200 in the musical device shown in FIG. 2. Although the connectors are shown located together in a single device, it should be apparent that other embodiments can use connectors from any one or more different devices or objects in the system, such as the recording system of FIG. 3.
Sensor 420 acts to detect a condition of one or more wires, lines or signals associated with connector 411. Other sensors can also be used to detect conditions of one or more other connectors such as 409, 410, 412 and 414. Depending upon the sensor, one or more conditions may be measured or detected for one or more connectors by one or more sensors. Sensor 420 can include, for example, a simple latch or circuit to detect a binary condition, or sensor 420 can include more complex circuitry such as a processor, memory, control logic, etc., to act as a communications bridge between signals at connector 411 and display circuitry (not shown) to generate virtual display icon 432 corresponding to connector 411.
Virtual display icons at 430 include icons or other graphics that show the state or status of a corresponding connector or of wires or signals in the corresponding connector. Information obtained from sensor 420 is used to update icon 432 so that the state or status of one or more conditions of connector 411 is continuously displayed. Communication links such as 418 and 422 are used to convey information between connector 411 and sensor 420, and between sensor 420 and display circuitry to cause a display of icon 432 on display 440. Display circuitry (not shown) can include a processor, memory, stored instructions, dedicated logic, custom, semi-custom or discrete components or other hardware and software to implement the display and/or control functions. Display 440 can be, for example, screen 110 in FIG. 1. Control inputs for the control functions can be the input controls described in association with FIG. 1 such as piano keys 120, touchpad and associated buttons 130, etc. Note that any suitable type of display or controls can be used and the display device, controls, display circuitry or other components of the input visualizer system can reside in any one or more musical devices or other devices such as those shown in FIG. 3. Such displays, controls, devices or other components may include any suitable components that are presently known or that are developed in the future.
The type and amount of information that is indicated by the icons or other graphics can vary depending on the embodiment. For example, a basic type of icon may just show the type (symbolically) or name (in alphanumerics) of the connector and whether the connector is coupled to a device. Other icons may include additional information such as the type of other device that is coupled to the connector, the type of signals that are being sent through the connector, etc. Table II below lists some of the types of information that may be sensed and used to generate a visual indication of the information by using an icon or other graphic associated with a connector. As used in this document, “icon” includes any form of alphanumeric or graphical depiction of information relating to an associated connector's sensed signals.
