Hi harpo,

Yamaha MIDI is "zero based".

This means that Patch #001 in most other synths is Patch #000 on Yamaha synths.

And it continues throughout that way.

"Roland-based" is "one-based" or 001 thru 128

"Yamaha-based" or "zero-based, the same patches are 000 thru 127

Inside BiaB in the GM menu is a setting to change BiaB to send Yamaha style, be sure to check that setting to true.
