How does a person aquire TWO PS-3100's? Is just the keyboard MIDI'd or do you have the SHX8 module on there as well to control individual parameters? I'm assuming it's just the keyboard that's MIDIfied. Still I've been scared of doing that to my MaxiKorg. I couldn't imagine doing it to a PS-3100. I can't wait 'til the SHX8 module gets firmware written for it so I can MIDI up a bunch of stuff.
