title: Web MIDI API not implemented in Chrome Canary?
body: <p>Support for the <a href="http://www.w3.org/TR/webmidi/" rel="nofollow">Web MIDI API</a> has been added to Chrome Canary <a href="http://www.html5audio.org/2013/06/web-midi-api-available-in-chrome-canary.html" rel="nofollow">since early 2013</a>. </p>
  
  <p>Why then, when I type <code>requestMIDIAccess</code> in the JavaScript console and hit enter, do I get "ReferenceError: requestMIDIAccess is not defined"?</p>
  
  <p>According to <a href="http://www.w3.org/TR/webmidi/#methods" rel="nofollow">official documentation</a>, it should be a defined function.</p>
  
  <p>What gives?</p>
