puzk,

You've planted this idea of midi'ing up keyboards in my mind. I've been playing arrangers for several years but just for fun and always only one keyboard at a time. Risking to sound incredibly stupid, but how does this work? How exactly do you "midi up" keyboards? And what's the result? Could I actually play my 9000 while using the voices of another keyboard or synthesizer? Sounds intriguing. Can you layer voices this way? Thank you for any pointers!

And to everybody else here: thanks for this great discussion forum!! I only joined a few days ago after being kind of a lurker for a couple months. So many of you guys and gals here are true professionals and you offer great insights.
