This is incredibly fun. When others joined and started making music together it immediately brought a smile to my face.

The greatest part about is the music created isn't terrible.

To me it sounds as if the reason for the music not sounding like total crap is, that the author uses pentatonic scales, which are also used in improvisations. (http://en.wikipedia.org/wiki/Pentatonic_scale)

I agree, I noticed that almost immediately. Also, the rhythms are quantized and the tempo is fixed.

It's still a very cool demo, though.

Second this comment, the real time feedback that you get and the realization that you aren't making something that doesn't completely sound like crap makes this surprisingly more fun than I thought it would be.
