This is an interesting thread, apropos of nothing I was browsing the reaper forum, there is a chap named Geoff Waddington who with others has developed an addon for reaper called the control surface integrator. One of the devices he has written configs for is the CMC QC - 2.
I have an AI , which I would love to be able to use elsewhere, it would be very useful in video editing software, so I will examine bomes to see how I go there.
Geoff has written very good documentation for CSI, so it should not be difficult to re-purpose other CMC’s.

there is some discussion making the software available for other DAWS such as able.
