I figured I would knock up synth loops, etc. in Logic and export the midi to the mpc. I've got a Korg ms2000r that makes some fun blip and blunks. I've never exported midi from logic to another sequencer, but I figure it is easily accomplished (i've only bounced tracks from Logic in audio, not midi). I also have recycle, left over from using reason alot...BTW i think you can export .WAV from Recycle, but I might be mistaken.
cheers
