Lee,
Great! Once you get ALL the details on which functions and the required MIDI messages that CAN be controlled from external MIDI device...then you can do the research, select and buy the right controller. I think the novation would be hard to beat.

That info SHOULD sure be documented in the manual...now I'm concerned if you can even do it? If not...I would return it to Italy!
I think Ketron mostly makes the modules for Accordian/Guitar players?
