Re: MIDI in Web Audio

Also, it works well in firefox 4 for Mac, though web audio in google chrome
performs poorly.

Google Chrome Mac (With Web Audio Enabled):

Primarily tested on Mac. Firefox 4 on windows seems to be slightly buggy
though with it, while firefox 4 Mac runs it perfectly.

Grant that's awesome! :)

For the record, I found the XAudioJS repository online here:
https://github.com/grantgalitz/XAudioJS

I noticed there was no README, but the code looks well managed so it's easy
to see what's going on.

Grant, did you do any testing with regards to performance across different
browsers/platforms? If so, what did you find? I remember you saying you felt
like Webkit in Safari on OSX gave you the best performance. Could I ask
which browser/OS you did the majority of the XAudioJS development work with?

Kind regards,

Alistair
