Simple game sounds on piezo speaker

I'd never come across beepbox - that's really cool!

Looking at the JSON it looks like you'll want to scan over it and change its form a bit first - basically go over all of patterns.notes.points and write them into times[patterns.notes.points.tick]=patter­ns.notes.pitches.

Then it'd just be a matter of using setInterval to scan over the times array one item at a time and do a beep if one was required.

Of course you could use Waveform too, but I'd start out simple :)
