Hi Peter
I'm afraid this does not work. If I set the RGB defaults to 0, 0, 0, the fixtures start outputting RGB values of 255, with intensity mapped to the fader to which it is assigned. This means that when I pull up the fader, they are white, as opposed to being "black" (which also doesn't make sense). The colour wheels also state values of 100 for red, green and blue. When operating the submasters in this configuration, as I pull up the submaster fader, the scene starts in white, and slowly becomes whatever colour it is programmed, as the fader moves up.
Returning to the original setting (defaults for RGB at 100), I perhaps should have added that it works in both ways. In other words, if I pull up amber first, followed by white, take down amber and then take down white, the white becomes amber. This happens for any programmed colour on any submaster. I have done this with other colours and the result is result is the same (in the new showfile I programmed submasters containing red, blue and green respectively (but with all colour parameters tagged)
Submaster controls colour needs to be on, as the submasters are programmed for theater shows, which require gradual fades between scenes, which aren't necessarily a fixed time (ie, I can't used colour fade times).
