Thanks

About your pitch bend question for the PolysixEX:
I found in the parameter guide on page 330 that
"To use another AMS source for pitch bend, modulate the TRANSPOSE or TUNE parameters instead.
BEND RANGE is not modulatable via AMS.
PITCH BEND RANGE is not modulatable via AMS."
Mini tutorial - different pitch bend values

Try the following with the AMS Mixer:
- Go to tab AMS Mixer.
Of AMS Mixer1 under section A + B select for AMS A: JS+Y and set amount to, say +20 (or +10)
For AMS B: JS-Y and set amount -50.
Go to tab Main and select the TUNE knob of the PolysixEX.
In the little grey window (bottom right) set for AMS: AMS Mixer1.
and Intensity: + 10.00.
Play a note and move the joystick up and down.
There you have it.
- for a bigger change, you can set the AMS for the TRANSPOSE knob to AMS Mixer1, instead of TUNE.
Intensity: +10.00 (higher values are possible but give a very big change).
With this method you can pitch bend 2 octaves for sure.
I hope this helps.
