On Cubase 10 it’s working very smoothly.
Took out yesterday to set everything up according to what Guy Rowland was suggesting here (thanks!) with everything disabled in VEPRO 7 on my slave and the memory footprint went from almost full (64GB) to 5GB.
Almost no CPU usage on idle.
Audio performance meter in Cubase showing barely any activity in my template with about 1000 tracks.
Happy days. Have to start thinking about what other libraries I can stuff onto my slave now
This new automation feature is a big time saver.
