I read about the group channel option in another post while researching, the Output Bus option is new but sounds like same amount of work. I hope Cubase will get updated to allow better routing…easier/quicker routing of tracks as inputs to other tracks (common feature in DAWS).
Btw - Render In Place is faster than real time and can cause dropout/pops/clicks/anomolies. I don’t trust faster than realtime anymore. Been burned too many times in the past. Thanks.
