Midi Mapping to D16 Phoscyon 2

Hi everyone, I currently am unable to midi learn D16 Phosycon 2 to my Arturia Minilab Mk2. I have clicked on the knobs on Phosycon 2 >midi learn>turned a knob on my Arturia but nothing seems to come up in termns of cc number or retain the setting after clicking save. Am I doing something fundamentally wrong here? Should I be setting up Phosycon 2 midi assignments through the Arturia midi assign software instead? Is there a Phoscyon 2 midi script for Arturia out there?
TIA
