Me too. I built a x0xb0x (http://www.ladyada.net/make/x0xb0x/ - it's a pretty impressive project, Ladyada does great stuff) a few years ago and play around with it occasionally, but I've realized I'm much better at enjoying other people's music than creating my own.

the 303 has quite possibly the worst interface in the history of the galaxy (imnsho)

I wasn't sure if it was 303 or the x0xb0x, but I agree (they're slightly different, I think. I haven't used a real 303)

Regardless, I'd love a x0xb0x :-P One day, one day...
