A similar solution for Linux (as the one described on Windows, using Midi Virtual ports etc) is this:
- install qmidiroute
- open qmidiroute
- If you use KXStudio w/ JACK or their repos (Recommended), use Catia (or qjackctl if you don't have Catia) to map arturia Midi out -> qmidiroute in (otherwise, on ALSA, use aconnect -i and -o options on terminal)
- on qmidiroute, add a Map
- change input type for "controller", value from "95" to "127"
Set your desired DAW / Software / etc to use qmidimapper out (again, using Carla or qjackctl or aconnect) and you're good to go.
Same caveats apply - you lose some fine-resolution (again, you are diminishing the knob resolution at a 1/4 via software to do a full circle, so by just 1 slight knob tap you jump 4 CC changes.)
Would be so much better to have the real deal... oh my.
