i do a littlebit… i used to control my lights with the copilot 2. its nothing fancy like inteligent lighting, but it would control up to 8 effects and had some pretty neat features for only 200$ it might even be cheaper nowadays. but if your looking at getting some more high end lasers and intelligent lights than im not your guy.
I’ve used a little bit of dmx at the first baptist that I’ve interned at. They have a control surface and a bunch of spot lights and lights on the stage. Someone programs in the lighting cues and then during a show someone cues the lighting events in real time. I know this stuff is really, really expensive, like more expensive than audio equipment. I’ve also done some research for that DJ paper that I did. You can find some DMX stuff at fullcompass.com
