I have the CS1000 in my living room with DMX over IP, and I have a midi controller an Akai APC40 for easy access for my shows. And 4 Eurolite scans and different mirror balls and a 8 channel DMX dimmer. And a few other effects.
if i were to make an educated guess based on the randomness of the patterns, its using a built in function and in sound mode.. I could be wrong though, and im basing it solely on my recent purchase of a "cheap(er)" version of a laser like this.
