Also DMX isn't always the way to go, in a situation where you have a lot of cues that coincide with LX cues it can often be simpler to hook into the MSC cues that a lot of desks send automatically. This negates the need for the LX programmer to have to add cues to trigger video when he is up to his eye balls in plotting the actual LX cues. He can then just add dummy cues on the odd occasion that there isn't an existing cue for you to piggy back on.
