Prototype javascript-based drum applet. Select a rhythm from the drop-down box, click 'Load' to make the notation appear, then use Start/Stop to play. Delay sets the tempo, as time in millseconds between beats; with javascript, it breaks up at about less than 250. Javascripts timer capabilitis unfortunately aren't up to the task here, so next step is to try protptyping this Flash instead.

Presets: Encoded rhythm:
Delay:

pattern will magically appear here when you hit "Load"...
