I still use my old Yamaha HC2 electone organ (I'm one of those strange older guys who still likes to play 2 manuals and bass pedals sometimes

The HC2 is around 30 years old - although being a Yamaha it still works perfectly !
The MIDI functions are pretty basic: MIDI out from top keyboard on channel 1, from the lower keyboard on channel 2 and from the pedals on channel 3
Can I configure the YC61 to receive that HC2 MIDI data and assign the 'upper' YC61 keyboard section to channel 1 - the 'lower' section to channel 2, and the organ bass pedal MIDI on channel 3 to a bass voice on the YC61?...
The manual describes using the YC61 as one part of a 2 keyboard set up, but this is slightly different?....
