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

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).
