MIDI connection - Help needed osx / Mod Duo X

I work on a Mac Catalina 10.15.7 and whatever I try, I can not have the Mod Duo X appearing in the MIDI studio interface of OSX…

I connected it :

  • directly to my Steinberg UR242 soundcard via Din MIDO cable (cable tested and working with other devices)

  • Using the USB MIDI host connected directly on my computer

No idea what to do to be able to access the DUO X via MIDI…

The MOD devices do not work as usb audio or midi interfaces, at least not yet.
For sending MIDI from your PC to the unit, easiest is a USB to MIDI DIN converter cable.
