I Just want to clarify something, MY DMX does not have multiple universes. If you look at the my dmx interface you will see only ONE dmx output. only one set of 512 dmx channels. not mulitple universes. The thing with my dmx is it allows you to create one show at a time on those 512 channels. This is equivalent to adding or taking fixtures out of your hardware console and reprogramming or modifying those scenes. Maks sense?
