I am starting the remote files work for the MPK MINI MK3.
If anyone wants to contribute, repo is here:
Currently I have not been able to source the midi map for the MK3 yet which seems a little different then the MK2. If you try and use the MK2 remotes, the knobs are different for the default program. Looks like this is a going to be a trial and error project untill Akai releases the midi mapping info.
