Abstract: A system for assisting an end user to develop a musical composition comprising a data storage medium, a plurality of musical assets stored in the data storage medium, a user interface, and an audio converter module. Each of the plurality of musical assets are associated with a functional attribute and a visual attribute, where the visual attribute provides a visual suggestion to an end user regarding the functional attribute of the musical asset. The user interface is coupled to an audio interface, a display driver and a user input handler; and is capable of rendering a graphical display that enables the end user to select between one or more visual attributes. The audio converter module captures audio recorded by the end-user through the audio interface, processes the audio; and produces a multi-track musical compilation comprised of a plurality of audio tracks mixed together in a manner where the multiple tracks are substantially musically harmonious with one another.

Abstract: A method for providing audio data corresponding to a requested musical note is disclosed, the method comprising: (a) providing a render cache having a plurality of cache entries, each of the cache entries corresponding to a different note; (b) receiving a request for a first note from a client; (c) identifying a first cache entry corresponding to the first note; (d) determining that a first audio segment corresponding to the first cache entry is not available; (e) identifying a second audio segment corresponding to a near-hit cache entry in the render cache; and (f) processing the second audio segment into a third audio segment that is substantially similar to the first audio segment.

Abstract: A method for applying audio effects to one or more tracks off musical compilation is disclosed. The method comprises identifying a first virtual musician to be associated with a first instrument track; identifying a first virtual producer to be associated with the first instrument track; applying a first series of effects to the first instrument track, the first series of effects being dependent upon the first virtual musician; and applying a second series of effects to the first instrument track, the second series of effects being dependent upon the first virtual producer.

Abstract: A system and process for producing a more harmonious musical accompaniment for a musical compilation, the process comprising determining a plurality of probable key signatures for the musical compilation, creating an interval profiling matrix for each of the probable key signatures, finding products of a major key interval profile matrix with each of the interval profiling matrices, summing each of the major key interval products into a running major key sum, finding a product of a minor key interval profile with each of the interval profiling matrices, summing each of the minor key interval products into a running minor key sum, and selecting the most probable key signature from the plurality of probable key signatures by comparing the minor key sum and the major key sum.

Abstract: An apparatus for creating a musical composition comprising an audio interface, an audio converter and a live looping recording session is disclosed. The audio interface operably receives audio from an input device and outputs audio to an audio output device. The audio converter module is operably connected to the audio interface to convert audio received via the audio interface into an audio track. The recording session module is configured to repeatedly playback a live loop that includes at least a portion of a first audio track, and to add at least a portion of a second audio track to the live loop during repeated playback. The first audio track may be a pre-existing track stored in a data storage medium. The recording session module may be configured to add at least a portion of a third audio track to the live loop during playback, which may be automatically generated based on one or more musical criteria of the first or second tracks.
