Hi - I have written to Yamaha via "Support" and wrote it up as a feature request. I also described this idea/request in detail to a (I think) US-based Tech Support person at Yamaha. Does anyone know of anything else I should do? A certain email address to write to? Or a thread on this or some other Forum, that Yamaha is known to look at?

I didn't try sending the SysEx commands, since my controller can't do that anyway, I suspect sending them would work fine, for a controller that can send them. I could try my old Peavey PC-1600x I guess ... but my real goal is to have "Organ Rotary Slow/Fast" added to the MIDI External Controller list of >100 functions they support.

Thanks all!
Jim
