Abstract: Embodiments of the invention include storing musical elements in a database and processing performance data, where the musical elements including a plurality of reference accent pattern data and a plurality of reference system pattern data. Processing performance data can include receiving input data corresponding to a musical performance, determining an accent pattern for the musical performance, matching the accent pattern data to one or more reference accent pattern data in the database, and selecting one of the matching reference accent patterns. Processing performance data further includes receiving input corresponding to a selection of a musical style, one or more musical performance parameters, and generating a musical accompaniment based on the processed performance data, the selected musical style, and the selected one or more musical performance.

Abstract: Systems and methods for selecting audio samples in response to musical stimuli are provided. In some embodiments, an audio sample can be selected based on the excitation state of an instrument. A musical stimulus can be received, and a current excitation level associated with previously received musical stimuli calculated. An audio sample can be selected for playback using the current excitation level. In some embodiments, audio samples having different velocity levels can be selected in response to repeated musical stimuli. A first instance of a musical stimulus having a first velocity level can be received, and a first audio sample corresponding to the first velocity level played back. A second instance of the musical stimulus having the first velocity level can be received, and a second audio sample corresponding to a second velocity level can be selected for playback. The first and second audio samples can have different audio characteristics.
