- MIDI Soundfonts: Pre-rendered General MIDI soundfonts that can be used immediately with MIDI.js
There is two generators for MIDI.js soundfonts:
- NodeJS package for creating soundfonts from WAV files - by Patrick Wolleb
- Ruby package for creating soundsfonts from SF2 files - by Mohit Muthanna
To dive in quickly Benjamin Gleitzman has created a package of pre-rendered sound fonts.
MIDI.loadPlugin.js - Decides which framework is best to use
// interface to download soundfont, then execute callback;
MIDI.loadPlugin(onsuccess);
// 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
onsuccess: function() { }
});
MIDI.Plugin.js - Controls MIDI output
MIDI.noteOn(channel, note, velocity, delay);
MIDI.noteOff(channel, note, delay);
MIDI.chordOn(channel, [note, note, note], velocity, delay);
MIDI.chordOff(channel, [note, note, note], delay);
MIDI.keyToNote = object; // A0 => 21
MIDI.noteToKey = object; // 21 => A0
MIDI.Player.js - Plays MIDI stream
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, onsuccess); // 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.
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!
});
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!
});
