Abstract
A computer-readable medium stores a data structure that encodes an audio performance for interactive playback. The data structure includes a virtual instrument pool, which encodes an interactive part of the audio performance. Audio content of the interactive part is encoded at least in a sequence of synthesizer control data. Each datum in the synthesizer control data specifies a digital sample of the audio content to be played back. The data structure also includes a global accompaniment pool, which encodes non-interactive portions of the audio performance. The global accompaniment pool includes timing information to synchronize the playback of the audio performance.
