From page 16 “troubleshooting” I quote…

“I can’t control MIDI!
□ Have you correctly connected the MIDI cable?
If you play this system from an external device:
□ Have you correctly set the MIDI channel in global mode? (→
p.14)
If you play an external device from this system:
□ Have you set the same MIDI channel for the receiving device
and for this system?”

Page 65 is a full midi implementation chart.

It includes velocity on and off as well as various cc’s for the knobs.
