LoopRecorder([retainThreshold=64])

Specify how many beats back in time to retain in buffer with retainThreshold.

Returns an instance of LoopRecorder - a WritableStream.

recorder.write(event)

Accepts an input of events in the ditty v2 output format. Usually you would pipe in events from something like soundbank-trigger.

Stores each id channel separately.

recorder.write({id: 'C', event: 'start', position: 0})
recorder.write({id: 'C', event: 'stop', position: 0.9})
recorder.write({id: 'F', event: 'start', position: 3})
recorder.write({id: 'F', event: 'stop', position: 3.5})

recorder.getLoop(id, from, length)

Specify the channel using id. Choose the in point using from and the out with length.

Returns an array of [[position, length], [position, length], ...] with position relative to the chosen length (event.position % length).
