Greetings,
It seems odd to me you can have a grandmaster mapped to a fader set at zero. When you then unmap it, the system still says master at 0%. Has anyone else noticed this?
I had a show file loaded with a fader assigned as the grandmaster. I then merged in the fader configuration from another show file that did not have a grandmaster, but was using the same faders. Once the merge completed, I now had the GIO reporting grandmaster at 0% with no fader to control it.
Maybe it is meant to do that, but I found it odd.
