Hi
I've tried to run rotor via MIDI in MJ+. In midi implementation chart I found information:
CC30 = 0 off
CC30 = 64 slow
CC30 = 127 fast
I've tried to send this commands from Cubase to MJ+, but it doesn't work.
I've used all organ sounds from MJ+.

Has anybody tried to do it?

I have request to SD-5 users:
Could You spy what message is sending through MIDI out while pressing ROTOR ON, SLOW, FAST?
