Needs much work.
The base concepts for this thing are pretty awesome, but it could use a lot more polish and the interface is TERRIBLE. Spent more time trying to figure out how to save one of my "recordings" than I spent enjoying said recording. It needs some serious work, but if that work were put in, Id buy it for five dollars!
Oh and what the other guy said, you need X11 for it to work :s
