coremidi

allow Node.js to interact with CoreMIDI services on Mac OS platforms

Usage

coremidi exports a function which returns a stream. MIDI messages are sent by writing an array to the stream.

Simple example

Playing middle C:

var coremidi = require('coremidi')();
 
coremidi.write([144, 60, 127]);
setTimeout(function() {
  coremidi.write([128, 60, 0]);
}, 2000);

Example with midi-api

var coremidi = require('coremidi')
  , midi = require('midi-api')()
 
midi
  .bank(2)
  .program(4)
  .rest(500)
 
function maj7 (root) {
  midi
    .noteOn(root)
    .noteOn(root + 4)
    .noteOn(root + 7)
    .noteOn(root + 11)
    .rest(1000)
    .noteOff()
}
 
maj7(60)
maj7(61)
maj7(62)
maj7(63)
 
midi.pipe(coremidi());
