STATS: OSX Leopard, Logic 8, Midisport 4x4(MAC), Roland XP50 ISSUE: I can only seem to use one patch for my mulitiInstrument (Roland XP50). SYMPTOM: With all 16 midi channels available in the environment, I can call up a patch to record one track, but when I try to record another track, any new sound will take place of the sound of the previous track on a different Midi Channel. Interesting enough, it doesn't do that with the other modules. Just this one lately. QUESTION: How can I get it to utilize all 16 channels of my XP50 as before? Please help if you can. THanks!
