I installed 1.9.1.9.0.30 last Friday night. I have been using the multi channel fixtures for a couple months, and never saw a problem, until today on set.
At first I thought I was pushing the wrong encoders or buttons, but this problem happened almost every time I tried to set levels with multiple fixtures at the same time, so the last time I did all the key strokes slowly and cautiously.
I hope I'm not 'jumping the gun here, and it is operator error, but I'm in production shooting so I cannot test it out now.
So I'm running 1.9.1., and so far, every time I change the intensities of my multi-intensity fixtures(Luma panels & 6 light coops) at some point when pressing the encoder(this last time for Intensity #3) to go to Minimum, it grabs and zeros the whole fixture. All 6, or 12 intensities, and the virtual master. First night scene of the season, meaning I have usually had all of these fixtures @ full, but still, I never saw this prior to 1.9.1. I think it is only when I select a group of, or multiple fixtures. My solution has been to do each channel individually, were it seems to function correctly.
Sometimes multiple fixtures seem to work properly, but not always.
