I'm a complete idiot when it comes to MIDI. I need some serious help in this area.
Here's what I want to do (if it can be done)...
I want to control my PSR3000 with my Roland KR7 (which is an 88 key 'intelligent piano', as they call it.) Is there a way to assign different channels so that I can control the accomp. of the 3000 and bring in the voices into the KR? In other words, can I turn the 3000 into a virtual Clavinova by connecting it to my Roland KR7?
Or am I dreaming? I realize it will be quite involved mapping this all out via email, but if one of you would be willing to come to my house and set it up for me, I would be very grateful...well, maybe that's a little too much to ask, but anyone who has a strong working knowledge of MIDI - please advise.

Thanks in advance
Tim
