Simple midi to javascript ( actually coffee-script ) function mapper.

install instructions

npm install


make start


./node_modules/.bin/coffee app/start.cofee

how to use it

Once you run it and choose your midi device it will create a server at localhost:1337

Then add to your html file ( generally your index file? )

<script src="http://localhost:1337/"></script>

At the moment there is a very simple and just broadcast the deltaTime / midi message via, in short you can retrieve them with

socket = io.connect('http://localhost:1337')
socket.on 'message', ( data ) =>

	message = data.message

	type   = message[0]
	number = message[1]
	value  = message[2]

Shold be very easy to change the transport ( ) to something else
