I find it so amusing that the 303 in MC303 does still make people think 'Acid'. Good marketing maybe...

I think that's cruel calling it rubbish. Ok, it is rubbish, but it was fun when it came out. Got me started, and I still use the sequencer sometimes for some of the crazy groove quantize patterns. My girlfriend at the time bought me one when I was getting into making tunes and at the time there wasn't such things as reaper and free VSTs for skint people. Bless...

Anyway. Yeh, you won't get one piece of hardware that'll make a whole good track without spending gazillions on some uber keyboard.

Either a control surface, or keep collecting boxes.
