Abstract:
The present invention provides a system and method for generating an output file including steps of generating audio or MIDI content blocks from one or more musical performances; receiving an input file having audio or MIDI music content; determining a chord structure and tempo for the input file; generating a harmonic chord map from the chord structure and tempo for the input file; using the harmonic chord map to automatically select content blocks, and generating the output file by combining the selected content blocks and the input file. The invention enables the creation of unique and new musical accompaniments by re-purposing audio or MIDI content from back catalogs and/or out-takes of musical works. The new arrangement may be provided in multiple music styles, genres, or moods and may contain performances from multiple musical instruments, which may be pre-recorded from live instrument performances and/or of MIDI generated musical content.

Claim (Index 21):
A computer implemented method for generating an audio or MIDI output file, the method including using one or more processors to perform steps of:\n generating audio or MIDI content blocks from one or more musical performances; wherein generating the audio or MIDI content blocks comprises:\n receiving an audio or MIDI file including content in a harmonic key from at least one musical performance; \n determining the harmonic key of the musical performance, and \n storing the audio or MIDI file as an audio or MIDI content block. \n receiving an input file having audio or MIDI music content; determining a chord structure and tempo for the input file; generating a harmonic chord map from the chord structure and tempo for the input file; using the harmonic chord map to automatically select a subset of the audio or MIDI content blocks, and wherein using the harmonic chord map of the input file to automatically select the subset of the audio or MIDI content blocks comprises:\n selecting one or more instrument types; \n for each instrument type of the one or more instrument types:\n identifying a set of content blocks for said each instrument type that matches the tempo of each bar of music in the harmonic chord map, and \n for each bar of music in the harmonic chord map, automatically selecting, from the set of content blocks, a content block that is in the same harmonic key, or that has a part or section that is in the same harmonic key, as the bar of music; \n \n generating the audio or MIDI output file by combining the subset of the audio or MIDI content blocks and the input file.
