Canvas Beat

Circular pattern UI similar in some ways to the iOS app Figure: https://itunes.apple.com/us/app/figure-make-music-beats/id51...

Acid Defender is another WebAudio drum machine simulator/game:

Looks cool, and sounds cool, but I've been playing with it a few minutes and still haven't quite worked out the UI.

Clicking on one of the rings but in the left half of the screen modifies the beat for the "pattern", and the right hand is "sample". I think I understand "pattern" but still trying to work out what "sample" does.

EDIT: Clicking on the left hand side changes the beat pattern, and the right hand side changes the sound associated with that ring! Got it :)

Would benefit from some instructions IMO.

Also there has to be a better way to increase the BPM than by getting 1 increase per mouse click.

Super tight. Adding a better way to change the BPM would be my only suggestion.

Looks slick - but Firefox complains about invalid audio buffer data, and doesn't play anything.

pretty cool! I would appreciate an easier way to turn rings off too
