What it does

  • Decode MIDI events
  • Check MIDI events (using strictMode)
  • Calculate needed buffer to encode MIDI events
  • Encode MIDI events

What it doesn't do

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);
