This is a resilient problem I've now been dealing with, including a laser (X-laser Aurora RGB), Chauvet 375Z, and Martin THRILL Fogger. Address and universe are set correctly on the fixtures, but there is no response to any parameter changes at all. Sometimes, I've been able to fix this by rebooting the console. But that often doesn't fix it. I'm preparing to use this console in a new live music venue that's about to open in 3 weeks, and I'm starting to experience some 'buyer's remorse'.
