Yeah, they are selected in fixtures and nothing happens:/ Like I was saying all other options work perfectly so I don't know where the problem is ...
MAX2 mode has the Master Intesity option, and that can be accesed with the wheels as a Dimmer alright. But, what I'm looking for, is to black the whole scene out, which means kill all the lights pressing one button (as blackout button should be working) or sliding one slider (grand master ..). But that doesn't work, only the PixelPars stay on, so to black the whole scene out I need to press Blackout button for all the lights and slide the Dimmer wheel down to 0 at the same time - which is a solution, but it's still an inconvenience during the show.
