// 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.noteOn(channel, note, velocity, delay);
MIDI.noteOff(channel, note, delay);
MIDI.chordOn(channel, chord, velocity, delay);

MIDI.keyToNote = object; // A0 => 21
MIDI.noteToKey = object; // 21 => A0
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!
});

Color.Space(0xff0000, "HEX>RGB>HSL");

DOMLoader.sendRequest(src, callback);
