Scott, what you could try, is load up MIDI-OX and see just what midi messages are generated when you push either a registration button, or a MF selection.

I am sure there will be some midi communication from the panel switch to the software sections...

Worth having a look???

EDITED TO ADD: Although thinking about it some more, even if you can get the data, it's not much use if Yamaha have blocked the reception of it via MIDI in.

I have no idea WHY they would think allowing a user to select a registration from an external MIDI device is a bad thing???

Oh well, thats one thing at least...I will NOT be buying a Yammie anytime soon
