Hi Scott

Yamaha has its manuals online. In response to Paul's suggestion, I doubt many PSR9000 owners have their arranger configured so that they can resolve the issue. Frank Rosenthal might be a good person to ask, since he has used a PSR9000 with an MFC10 foot controller. (I would be very surprised if the foot-controller info could not be sent out one of the two midi outs of the PSR9000.) I could only test on a PSR8000, which nobody is planning to buy anyway. I also think midi merge is likely to be built into high-end arranger modules, like the Solton X4 and the Korg i40m. Also, it is likely to be found in any arranger with two midi ins. To me this is not an important issue, since I have a controller with multiple midi outs and a module with two midi ins.
