OK... here is my dilemma: I am trying to have 2 Midi Controllers. I have a keyboard and my MPC2000XL that I would like to control different synths. Sometimes I want to be able to use the MPC to play (record) drums, sometimes I want to be able to use my keyboard for pad, horn, synth sounds basically. I don't want to have to change midi cables every time. I have a Midi Thru Box and I have a Terratec EWS88MT soundcard. I also have the Planet Phatt, Alesis D4, Orbit, ESI200, Nanobass, Dr 5, and some other synths. How exactly would I set up my Midi Cables to do this. My keyboard has one out, one in and thru. The MPC has in/out A & in/out B. I believe the MPCs in/outs are totally independent. HELP!!! PLZ. Thanks in advance.
