DON'T DO IT. I just recently tried to go that route. Ooh Wee was that a bad move. I have a lot of gear so I had to get a MOTU midi timepeice AV, then having to open up an AUX track for each instrument, then creating all the midi tracks in the sequence, scrolling through the pulldowns to pick your inst., then you have to convert the midi to audio, and hope your cpu can handle all that . Fucked me up. I had it hooked up for like a week just to see if I could get used to it. Too much pointin and clicking to make a track, I wouldn't say it's difficult , just a long process. I just bought a MPC4000 last week, and this shit is lovely. I used a MPC2000xl for the longest time , that's a cool piece too.
