Many months ago (almost a year!) I built a little standalone box for a specific job that controlled the ATEM audio from the vision control.
It worked by initially setting the individual audio faders default levels and then turning on the required audio channels.
Then the vision TBar and input buttons from ANY panel controlled the audio faders positions.
If a video input was selected, its associated fader went to the preset level MINUS the fader position.
So if the TBar was all the way over one side, the audio fader would be at its max (its initial setting).
If the TBar moved, the respective audio faders would increase (for the 'going to') and decrease (for the 'coming from'). Also known as a 'cross fade'.
I also remember starting on the 'dip' code where it would fade out then fade in but never finished it because it wasn't required for the job. I also vaguely doing the FTB code. That was oh so many beers ago!
The project was for a 'Master Control' switcher installation.
I am willing to resurrect the project if you are willing to part with some cash!
