Cubase 13.0.20 Mac Ventura 13.5.2 iMac
I see this same issue popping up from a post in 2012 “Issue with Muting Folders in Cubase 6”…
I use Folders for organizing instrument groups and do lots editing/muting etc. If I accidentally “X” Mute a Group, I can’t undo it and get back to the status everything was in…it unmutes the WHOLE folder rather than returning to the previous settings.
MAJOR bug for me as I just have to quit and hope I can figure out what I had changed since I last saved (which I save often).
