Firefox support?

[josephernest]

Thank you @cwilso for this cool example of Web Audio / Web MIDI!
Currently it works out-of-the-box on Chrome :)

I thought that thanks to your polyfill/shim on Line 7:

<script src='//cwilso.github.com/WebMIDIAPIShim/lib/WebMIDIAPI.js'></script>

it would work out-of-the-box on Firefox too, but it doesn't. On Firefox 60 (latest), we have: No MIDI support present, even with this WebMIDIAPIShim.

Question:

• I tried without WebMIDIAPIShim, but it still works on Chrome, and still doesn't work in Firefox (i.e. no difference). So what does WebMIDIAPIShim add in this precise example?

• How to make this example work in Firefox, as of today (Firefox 60)?
