Right now, over USB probably not.
The nice thing about the Keystep though is that it has DIN-MIDI as well, which will work (and in the future with the CV’s too 
). Since its working on the MOD Duo it should be able to get working with the MOD DuoX as well, again its most likely a driver issue (luckily there is @falkTX performing his Linux magic 
we will be addressing this soon! ).
