This player does not generate any audio, but by attaching a handler to the event emitter you can trigger any code you like which could play audio, control visualizations, feed into a MIDI interface, etc. Demos Neopixel Music by robertvorthman @robertvorthman Autocomposer by RJ Salvador @rjsalvadorr Simple Browser Player by Garrett Grimm @grimmdude Orchestra by Daniel Alejandro Cast @lexcast Getting Started Using MidiPlayerJS is pretty simple. Create a new player by instantiating MidiPlayer.Player with an event handler to be called for every MIDI event. Then you can load and play a MIDI file. Player Events There are a handful of events on the Player object which you can subscribe to using the Player.on() method. Some events pass data as the first argument of the callback as described below: Note that because of a common practice called \"running status\" many MIDI files may use Note on events with 0 velocity in place of Note off events.
