navigator.requestMIDIAccess() method breaks code #16

Closed bignimbus closed 10 years ago

bignimbus commented 10 years ago

The following line causes WAD to break in Chrome Version 35.0.1916.153 m (Windows 8.1):


// line 871 in WAD.js
navigator.requestMIDIAccess().then(onSuccessCallback, onErrorCallback);

Console returns: Uncaught TypeError: undefined is not a function.

Will try to hack a solution in the meantime.

I think I know what the issue is. For one thing, MIDI access is an experimental feature in Chrome, and it has to be enabled separately. Check this out: http://stackoverflow.com/questions/21821121/web-midi-api-not-implemented-in-chrome-canary

Also, you may need to install the Jazz plugin from http://jazz-soft.net/ to give your browser low level midi access. I've done both of these things, and MIDI works fine on my system (Chrome, MacOS 10.9).

Thank you for adding this fix. I certainly don't expect people to enable experimental features in order to do simple things with WAD.
