I hate that. Drum parts are okay, and you can set parameters for each of the 16-notes. Not enough for the drum parts. Synth sounds awesome, almost like a real synth. The machine is not complex, but they could've added more firmware into the unit, and clean-up the interface, and add a few more effects functions.
Noise generator is definately a plus.
Get one used, I took mine back. Mars were good, tho, got two free cables out of them when I returned it. I don't think either. Nice machine, but read on. So it sound like an echo or a heavily EQ'd version of the beat.
