smashngrab, this combo kinda sorta sucks, in my opinion.
I was playing with my old MC 303 the other day, borrowed it back from the friend I traded it to to see if I could sequence it with MPC.
No dice.
The 303 can function as a tone generator, sure, you have to reset it into that config or send the proper CC to it. But one thing about tone generator mode: Only one channel. This means you can only play one instrument off the 303 at a time, as sequenced by an external device, which quite frankly sucks. It's the whole point of a "groovebox" to have multiple sounds available at once. Roland bombed on this one.
In internal sequencer mode, you could certainly program an entire song to sync to the MPC, but it's not worth it in my opinion, this combo.
Maybe if you have a keyboard and are a skilled keyboardist, but I am not and have not. The 303's internal sequencer bites. For drum patterns it's alright, though locked to a 16th-notes only grid, x0x style. For the internal synths, you have to either record em real time or program in step mode. I don't know for certain but I believe step mode is not steppable by the MPC, so you're on your own trying to figure out where the hell you are.
I always hated the 303's synth sequencer and it's the main reason I traded it away in the first place. It's got some kinda cool sounds and knob tweaky editing, but I would never pick up another 303 if I had the chance. Sell it if you value your sequencing.
Hope this helps.
