I am a sound and light engineer for a theatre performance and i've build a small patch that controls both the light cues for the dmxusbpro by Enttec (external can be bought here: http://www.nullmedium.de/dev/dmxusbpro/)
and the PreSonus studiolive 16.0.2. So now you can go through Scenes and Cues with just the touch of a button. its very functional. I'm still working on the part where you can have different fade in and fade out times for each cue. I'll post it as soon as its ready.
Anyway, I've been taking lots of stuff from this website, so I thought i'd give something back...
All the best & have fun,
