• MIDI.loadPlugin.js:  Decides which framework is best to use, and sends request.
    • 

  • 

    // interface to download soundfont, then execute callback;
MIDI.loadPlugin(callback);
// simple example to get started;
MIDI.loadPlugin({
	instrument: "acoustic_grand_piano", // or 1 (default)
	instruments: [ "acoustic_grand_piano", "acoustic_guitar_nylon" ], // or multiple instruments
	callback: function() { }
});

    • 
 
  • MIDI.Plugin.js:  Ties together the following frameworks;
    • 
 
  • MIDI.noteOn(channel, note, velocity, delay);
MIDI.noteOff(channel, note, delay);
MIDI.chordOn(channel, chord, velocity, delay);
MIDI.chordOff(channel, chord, delay);
MIDI.keyToNote = object; // A0 => 21
MIDI.noteToKey = object; // 21 => A0

  • MIDI.Player.js:  Streams the MIDI to the browser.

  • 
 
    MIDI.Player.currentTime = integer; // time we are at now within the song.
MIDI.Player.endTime = integer; // time when song ends.
MIDI.Player.playing = boolean; // are we playing? yes or no.
MIDI.Player.loadFile(file, callback); // load .MIDI from base64 or binary XML request.
MIDI.Player.start(); // start the MIDI track (you can put this in the loadFile callback)
MIDI.Player.resume(); // resume the MIDI track from pause.
MIDI.Player.pause(); // pause the MIDI track.
MIDI.Player.stop(); // stops all audio being played, and resets currentTime to 0.
Callback whenever a note is played;
MIDI.Player.removeListener(); // removes current listener.
MIDI.Player.addListener(function(data) { // set it to your own function!
	var now = data.now; // where we are now
	var end = data.end; // time when song ends
	var channel = data.channel; // channel note is playing on
	var message = data.message; // 128 is noteOff, 144 is noteOn
	var note = data.note; // the note
	var velocity = data.velocity; // the velocity of the note
	// then do whatever you want with the information!
});
Smooth animation, interpolates between onMidiEvent calls;
MIDI.Player.clearAnimation(); // clears current animation.
MIDI.Player.setAnimation(function(data) {
	var now = data.now; // where we are now
	var end = data.end; // time when song ends
	var events = data.events; // all the notes currently being processed
	// then do what you want with the information!
});
