Don't know if this has been suggested before, and don't think it exist's as a current feature, so here it is:
What about having a way to select one, or more sources, say generic and fixtures when programming memories and/or submasters?
It would really make life easier for folks like me, who work in a (small) pub, where most of the bands doesn't bring their own lighting tech, the stagelighting is required in order to work on stage before a show, time is scarse before the concert starts, and where in 90% of the cases, nobody have a clue as to what they sounds like.
If I could choose between say, all; fixtures and generic, it would enable me to program memories containing fixtures only, while at the same time having the generic lighting on, without affecting the memories.
Another suggestion: How about a stand-by function for the submaster (and memories), where you would be able to select the next submaster/memory to be executed, with the moving heads going into the correct starting positions, with all the attributes set.
