my xp-30 midi ports r connected to my SB Pro card (oldie) joystick ports, on my Pentium MMX 223 with 64 MB RAM, Cakewalk PA 8.04, and an AWE64 G Card. I used my SB Pro as a MIDI interface bec. the AWE didn't work with my XP-30(with stuck notes, random patch changes, and stuff occurring when i record MIDI tracks). For about a month, the setup worked, and i was a happy guy. But now, all of a sudden, this setup is having problems. when i try to use non-GM patches of the XP-30, the synth and Cakewalk hangs. But when i go to GM mode, everything works fine! Why? I really would appreciate the help. Thanks in advance.
