humanize-midimessage v1.1.1

humanize-midimessage

MIDIMessageEvent is how your browser communicates signals from your MIDI devices. The event contains 3 bytes that correspond to various things in this table

That table isn't very readable by people like me so this library makes it readable by people like me.

Installation

$ npm install humanize-midimessage

Usage

In your HTML:

<script src="humanizeMidiMessage.js"></script>
<script>
	navigator.requestMIDIAccess()
	.then(function (midiAccess) {
		midiAccess.inputs.forEach(function (port, key) {
			port.onmidimessage = function (event) {
				console.log(humanizeMidiMessage(event));
			}
		});
	})
</script>
