to the Genesys, your query re Right hand control:
I haven't figured out how to do that yet. The arranger keyboard has only one Midi IN socket and I have this transmit and receive on channel 3 (LH on the KN), hence I control the left hand chord and voice only.
I also have a setup where I use the arranger keyboard in Pianist mode and layer its sound with one or more from my sound module, and play the whole thing from the 76 keys, using Midi Channel 1.
Maybe there is a way to get complete control from the controller keyboard but I haven't worked it out yet!
regards
Keith
