KeyStep Mod Wheel into Octatrack

Hopefully this is basic…

I’m using my KeyStep 37 (ch 16) into my Octatrack using the OT’s auto channel (ch 16), then controlling my Novation Peak (ch5) via the OT/KS.

Everything is working fine, aftertouch goes through to the Peak from the KS37, pitch bend too, but the mod wheel doesn’t.

Also, cc’s I have set up on the KS37 to control the Peak’s filter (cutoff, resonance) aren’t passing through the OT to the Peak.

What am I missing in the OT? Do I need to activate the CC’s or is there a dedicated setting?
