I posted this a while back:

Simple MIDI setup:

.... presuming you are using a master keyboard and splitting the keyboard as channel One upper and Two lower:

MENU -> F2 MIDI -> F6 CHANNEL RX ->
F1 Upper: 1
F2 Lower: 2
all others OFF then:
F9 Arranger Chords ->
F6 Lower 1: 2
F7 Lower 2: 2
all others OFF

and lastly press "SAVE" (under the cursor keypad)

Then go into Menu -> keyboard control -> F5 accordion -> user 1/6 (change to INACTIVE).


and then USER 5/10 'SAVE'

That should get you started although you may need to change the octaves for upper/lower. The latter instructions ensures good chord recognition.

If that does not work then you will have to look at your master keyboards midi setup.

You could also try using the different MIDI Templates ketron have supplied from the MIDI screen just to get a basic setup (the USER buttons). But you will still need to alter them to get the module working perfectly.

Other than that, give your retailer a call, most Ketron agents will have a good working knowledge of the instrument (unless you brought it at discount online of course!)
