A script file includes a text section that has a text label to designate a point during execution of the script sequence when an audio rendition of a video event is to be initiated. The script file also includes a container that maintains audio content within the script file. The audio content is identified in the container with a content label that corresponds to a text label in the text section. The audio content is initiated to be generated as the audio rendition at the designated point during execution of the script sequence when the script file is executed and when a script processor determines that the content label corresponds to the text label.

Scripting solution for interactive audio generation

A performance engine selects note patterns from a pattern style containing a plurality of note patterns. The note patterns are categorized by embellishment type and by ranges of playback levels. In addition, a beat pattern is specified for each note pattern, indicating the chord rhythm with which the style can be used. The beat pattern is a bit array, with bits corresponding to every beat of one or more contiguous measures. In response to selection of a particular embellishment type and playback level, the performance engine selects a note pattern that meets the following qualifications: (a) it is of the selected embellishment type; (b) its designated range of playback levels includes the selected playback level; and (c) its beat pattern indicates that it can accommodate chord changes at the beats at which such changes occur in the currently selected chord progression. If there are no qualifying note patterns, these conditions are gradually relaxed until at least one of the note patterns qualifies.

Supporting arbitrary beat patterns in chord-based note sequence

A system and a method for the notes of one track to move in a harmonically separate manner from the notes of another track when the notes of each track are played against a chord progression. Each track is associated with a chord function. The notes of the tracks are then played against a progression of polychords, where each polychord consists of one or more chords. In addition, each chord of a polychord is associated with one or more chord functions. During operation, each note of a track is mapped against a chord of the currently playing polychord. The chord for each track is selected by identifying the chord of the polychord that is associated with the same chord function as the track. Furthermore, individual tracks, groups of notes, or single notes can be assigned to one of several playback modes. Each note includes a field that identifies a playback mode. In addition, each track is associated with a playback mode. Prior to generating a performance note, the playback mode for the note is determined, and the note is transposed or mapped against the currently playing chord in accordance with the playback mode.

System and method for enhancing musical performances in computer based

The present invention provides a system and a method for intelligently controlling note inversions during a computer based musical performance. During a musical performance, notes of a track are transposed against a chord. In some instances, the resulting pitch of the transposed note may fall outside of an upper-pitch boundary or a lower-pitch boundary defined for the track. Two additional control mechanisms are examined to determine if the note should be inverted. One mechanism includes a chord inversion mask used for managing the inversion of notes within the context of the chord. Another mechanism includes a track inversion mask defining one or more series of ranges where inversions are allowed. If the pitch of a transposed note exceeds the upper-pitch boundary or the lower-pitch boundary, the chord inversion mask and the track inversion mask are scanned to determine if the note can be inverted. The scanning process includes looking at each position in the chord inversion mask and the track inversion mask between the exceeded boundary and the pitch of the transposed note. If a position is found in which the chord inversion mask and the track inversion mask allow inversions, then the note will be inverted.
