When using the higher patches with Roland hardware and a BIAB .PAT file, my experience is that you do not send a GM or GS ON command, nor set it to either of those modes upon initialization. You need to set the hardware unit to initialize in its 'native' setting.

Larry, you mentioned Korg & Yamaha products too. The Yamaha uses a different numbering system, one digit different that Roland. It means the same .PAT file cannot possibly work. Not sure about Korg, but Gary Curran would know.
