Methods

addMidiCC({required int ccNumber, required int ccValue, required double beat}) → void
Adds a MIDI CC event to this track. This does not sync the events to the backend.
addMidiPitchBend({required double value, required double beat}) → void
Adds a MIDI pitch bend event to this track. The value must be between -1 and 1. This does not sync the events to the backend.
addNote({required int noteNumber, required double velocity, required double startBeat, required double durationBeats}) → void
Adds a Note On and Note Off event to this track. This does not sync the events to the backend.
addNoteOff({required int noteNumber, required double beat}) → void
Adds a Note Off event to this track. This does not sync the events to the backend.
addNoteOn({required int noteNumber, required double velocity, required double beat}) → void
Adds a Note On event to this track. This does not sync the events to the backend.
addVolumeChange({required double volume, required double beat}) → void
Adds a Volume event to this track. This does not sync the events to the backend.
changeVolumeNow({required double volume}) → void
Handles a Volume Change event on this track immediately. The event will not be added to this track's events.
clearBuffer() → void
For internal use only. Clears any scheduled events in the backend.
clearEvents() → void
Clears all events on this track. This does not sync the events to the backend.
getVolume() double
Gets the current volume of the track.
midiCCNow({required int ccNumber, required int ccValue}) → void
Handles a MIDI CC event on this track immediately. The event will not be added to this track's events.
midiPitchBendNow({required double value}) → void
Handles a MIDI pitch bend event on this track immediately. The event will not be added to this track's events.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
startNoteNow({required int noteNumber, required double velocity}) → void
Handles a Note On event on this track immediately. The event will not be added to this track's events.
stopNoteNow({required int noteNumber}) → void
Handles a Note Off event on this track immediately. The event will not be added to this track's events.
syncBuffer([int? absoluteStartFrame, int maxEventsToSync = BUFFER_SIZE]) → void
Syncs events to the backend. This should be called after making changes to track events to ensure that the changes are synced immediately.
topOffBuffer() → void
For internal use only. Triggers a sync that will fill any available space in the buffer with any un-synced events.
toString() String
A string representation of this object.
