Unfortunately, I need folders in the mixer so that when I collapse a folder the channels inside collapse with it, I do actually use Avid S1 hardware as well , the problem with the current system is you close to the folders in the arrange window but your mixer is still show all tracks. My workaround currently is to use the visibility agent to show certain selected tracks or truck types or track names.
There’s nowhere around it. We need a folder in the mixer as an option, which will sum audio.
