Midi show control?

  • Hello everyone! Happy new year!!

    I have a question, where can I find the function Midi show control?

    I would like to connect Show Cue Systems with Grand ma 3. The SCS give a "Go" to the Main cuelist. Normal I use this method in the Dot 2, I like to have this in the Grand MA 3.

    Or is there another way to get this working?
