Scott,

The interface between the 9000PRO and the MFC10 is midi however, no midi programming was required to setup the MFC10. I simply select the functions I want to control from a text menu (it said "Vocal Harmony ON/OFF") and the keyboard sends the correct midi signals. Once I've selected which function is controlled by each switch, I press END. The keyboard saves my settings and remembers them each time I power ON the keyboard. So, once it's setup, you don't have to do it again (you can change it any time you like).

So, anyone (even someone like me that doesn't understand a lot about midi signals) can setup the MFC10 to operate nearly any function on the 9000PRO without having to study the manual. Does the PSR2000 have anything about the MFC10 in it's manual? If so, it may work the same way as the 9000PRO.

I'll check it out tonight for you and see if I can find the info you want. If I find it, then I'll post it tomorrow for you.
