Why does my XP-30 MIDI setup only able to play and record in GM mode? When I move to Patch or Perf. Mode it just hangs and gets stuck. By the way, i use my PC with Cakewalk PA 8.04 for it. It used to work before, but now it doesn't. Its been this way for more than 4 months now, and doing all kinds of stuff to remedy it to no avail. Pls. guys, need your help! Thanks.
