For STPro you need to check and see if it has Logic Protocols or Mackie Protocols. I use to have that same board about 90years ago its a really good board for audio mixing. I miss mine even with a Roland 2480 in storage.
STpro likes Logic Protocols which i believe you just maybe missing. Even on a new mackie board you have to switch to Logic protocols.
It wont control FCP or Color that would be a different kind of board.
