Cannot get Polyend Poly 2 to work with Morph

Hello,

I tried using my Sensel Morph with my Polyend Poly 2 using the “Host” port but nothing happens, no gate, no pitch. Is this a problem related to MIDI channels?

I have the firmware 2.02 for the Poly 2. I know that 2.05 is out, but I read positive result on even older here in the forum.

Thank you.
