I'm trying to record several diffrent MIDI tracks on my MPC. Currently I have everything setup perfect to where the MPC will record MIDI data for one patch off the Roland, but if I swith patches on the Roland than it switches the recorded note info the that patch and plays a differnt sound. How do record several different MIDI tracks on my MPC from the Roland? And how do I make the MPC recognize that and pull up the differnt patches and MIDI info when I reload the song or sequence?
