Patent ID: 8198525

Claim:
A computer implemented method to collectively adjust tracks, the computer implemented method comprising: causing the display, by a first processor, of at least one internal track and at least one external track, wherein the first processor causes sounds corresponding to each of the internal tracks to be generated and at least one external processor external to the first processor causes sounds corresponding to each of the external tracks to be generated; collectively adjusting, by the first processor, at least one of tempo, tempo and pitch, and tuning of each internal track and each external track in response to receiving a command, wherein each internal track is one of an audio track and a MIDI track and each external track is a MIDI track; and wherein collectively adjusting the tuning further comprises adjusting the tuning of each track by an increment associated with the command, the increment being between about 220.00 Hz and 880.00 Hz, by pitch shifting each audio track by the increment and providing MIDI note values corresponding to the increment to each processor associated with each software instrument corresponding to each MIDI track.
