CODE EXAMPLES (from the repo)
* ./demo-Basic.html is the most basic implementation as seen here:
<pre>
MIDI.loadPlugin({
soundfontUrl: "./soundfont/", // path to soundfont directory
instruments: [ "acoustic_grand_piano", "synth_drum" ], // multiple instruments
callback: function() {
MIDI.programChange(0, 0); // change channel 0 to instrument 0 (acoustic_grand_piano)
MIDI.programChange(1, 118); // change channel 1 to instrument 118 (synth_drum)
for (var n = 0; n < 100; n ++) {
var delay = n / 4; // play one note every quarter second
var note = MIDI.pianoKeyOffset + n; // the MIDI note
var velocity = 127; // how hard the note hits
// play the note
MIDI.noteOn(0, note, velocity, delay);
// play the some note 3-steps up
MIDI.noteOn(1, note + 3, velocity, delay);
}
}
});
</pre>
* ./demo-MIDIPlayer.html shows how to parse MIDI files, and interact with the data stream.
* ./demo-WhitneyMusicBox.html is a audio/visual experiment by Jim Bumgardner
