CODE EXAMPLES (from the repo) * ./demo-Basic.html - the most basic implementation. * ./demo-MIDIPlayer.html - how to parse MIDI files, and interact with the data stream. * ./demo-MultipleInstruments.html - synth drum and piano playing together * ./demo-WhitneyMusicBox.html - a audio/visual experiment by Jim Bumgardner ------------- DEMOS * Color Piano by Michael Deal * Simon Says by Daniel Christopher * Brite Lite by Daniel Christopher * Euphony 3D Piano by Xueqiao Xu * VexFlow by Mohit Muthanna * Spiral Keyboard by Patrick Snels * Ragamroll by Mani Balasubramanian ------------- * 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 the instrument code 1 (aka the default)
    instruments: [ "acoustic_grand_piano", "acoustic_guitar_nylon" ], // or multiple instruments
    callback: function() { }
});
* MIDI.Soundfont.js: Customizable base64 Soundfont. * 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!
});
* Color.js: Color conversions, music isn’t complete without! 
Color.Space(0xff0000, "HEX>RGB>HSL");
* DOMLoader.script.js: Loads scripts in synchronously, or asynchronously. 
DOMLoader.script.add(src, callback);
* DOMLoader.XMLHttp.js: Cross-browser XMLHttpd request. 
DOMLoader.sendRequest(src, callback);
* MusicTheory.Synesthesia.js: Note-to-color mappings (from Isaac Newton onwards).
