So, to be clear, with your Mackie, can you (completely remotely) set a selection range like this scenario:
1] Pause, the transport somewhere in the song, and set "beginning of range" at that point
2] Play forward a bit, and pause transport, and set "end of range" at that point
No matter what the buttons are called ("Modifier keys", "Selection Keys") they still have to send "generic control surface commands"that Cakewalk understands, right?
I am trying to determine if the Mackie has some proprietary commands that: a) Cakewalk responds to (of course), but, b) other controllers cannot produce those same special commands.
