Usage

// Your variable with an ArrayBuffer instance containing your MIDI events
var anyBuffer;
 
// Parse MIDI events
var events = [];
var parser = new MIDIEvents.createParser(new DataView(anyBuffer), 0, false);
var event = parser.next();
 
do {
  events.push(event);
  event = parser.next();
} while(event);
 
// Check bufffer size before encoding
if(anyBuffer.length >= MIDIEvents.getRequiredBufferLength(events)) {
  console.log('ok');
}
 
// Encode MIDI events
var destination = new Uint8Array(anyBuffer);
MIDIEvents.writeToTrack(events, destination);
