I have something like this in linux using a novation launchcontrol, it's quite straightforward using aseqdump, say I use the buttons to switch desktops, I have this launched as part of my session and always in background. While developing this I just printed $line to see what aseqdump sent to figure out the regexes

    while IFS=' ' read -r line; do
      if [[ "$line" == *"client"*"Launch Control"\* ]]; then
        device=$(echo "$line" | cut -d' ' -f2)
      fi
    done < <(aconnect -i)

    aseqdump -p ${device::-1} | while IFS=' ' read -r line; do
        if [[ "$line" == *"Note on"* ]]; then
            note=$(echo "$line" | grep -o "note [0-9]*" | cut -d' ' -f2)
            if [ "$note" == "9" ]; then
                wmctrl -s 8
            fi
        elif [[ "$line" == *"Control change"*"127" ]]; then
            note=$(echo "$line" | grep -o "controller [0-9]*" | cut -d' ' -f2)
            if [ "$note" == "114" ]; then
                # some macro
            fi
        fi
    done

Repo is 2,500loc, all-in, according to SCC. Should be really easy to point your favorite coding agent at the repo and have it one or two shot something similiar in the language of your choice.
