I would love to find it in a new Cubase. When I create e.g. brass section on several tracks and routing to Group Channel for compression +FX channel for reverb I’m printing result on audio track and when done I’d like to have all this channels in a folder in disabled mode and get rid of FX and group and fx channels from mixer view. Hiding channel is not a solution in this case. Set, print, disable and forget and easy for future recalls when necessary.
