I like the "no musical skills required" part
Not sure if I would use it for anything serious, but it sure looks like fun to play with. Most of the time when I'm eating in a sandwich shop or something, I'm messing around aimlessly on my phone. Would be nice to be able to mess around with some music instead. Pity I just have an iPhone and not an iPad. There's a Maschine app for iPhone that looks fun though.
