I posted a fairly epic rant about the lack of understanding on the part of the Steinberg VCA programmers YEARS ago now.
So weird…deja vu in 2019. It really is embarrassing. I worked on 160+ input latge format Euphonix System 5 post consoles for years. The VCA and Automation in Nuendo is taken almost directly from the System 5.
I don’t use the VCAs in Nuendo. Pretty much says it all.
