I was wondering if anybody else experienced the same bug a i did. When changing pages with main cue lists on them, the lights with no intensity in the first cue go to full and then go to the desired level in the cue time. Even when the last level on the previous page was zero. The only way to get the right fade was to give them a zero intensity into the first cue.
This isn't a bug with group masters. They must exist on each page you want them to have effect. I tend to put them on a separate playback bar and adjust levels using Choose plus 5th encoder wheel.
