You have a few options on the express. First, see if your CD player has a contact closure play control (most denons do). If it does you can use the built in relay in the board to star/stop your player. You can also using MIDI TC (the express will not accept regular smtp). First however, what kind of CD player do you have?You could also program timecode in the board. Express consoles allow programming to timecode. Just feed it a timecode and it will do what you want at what times you specify. This eliminates the possibility of getting out of order with your cues. If something happens and the board skips a cue, then your sequence will be all messed up throughout the rest of the show if you were just feeding the board GO commands through MIDI. If the cues are programmed to go at specific times, then there isn't any chance of getting out of sync.
Consult your manual on how to do it.
You will have to program the TC to stop instself, run the cues in the drama manualy, then restart the TC. You can do this by doing macros pretty easily. TC can be a bit more forgiving in programming, but then again MSC also has its benefits. Personaly, with the express, it will prob be easier to do TC.
