LaunchpadJS

Interacting with a Novation Launchpad from your browser with the web MIDI API.

Usage

Install LaunchpadJS with bower via the following command

bower install --save LaunchpadJS

or download a distribution from releases.

Include launchpad.min.js in your html page

<script src="bower_components/LaunchpadJS/launchpad.min.js"></script>

Hook your Lauchpad or Launchpad Mini up to your computer and start writing an application. E.g. the following snippet turns on each button that is pressed to red.

launchpad.connect().then(function(pad){
  pad.clear();
  pad.on('press', function(button){
    button.turn('red');
  });
});

Now open your page in Chrome the only browser that natively implements the Web Midi API at the moment.

See the wiki for an overview of the API

Development Notes
