So I am trying to record more than 1 sound to my MPC2000xl using my Keyboards via Midi. I have hooked up the midi cable (in and out) and have followed all the instructions according to the instruction manual but still no luck. I have changed my track in the same sequence and the midi to 2a, 3a etc... but still the sound changes from what I recorded in 1a when you try to add a different instrument. I know it is hooked up correctly because it records what I played in 1a but if I can do 1-16 why is it so difficult to add on 2 threw 16? I need help in the worse way can anybody help!!!!!!!!!!!!!
