This is actually an issue which somebody reported a few years ago, as I read.
However it is still happening on Cubase 12.
I use VCA track to control the volume of some audio tracks, then every time I start Cubase and open that project, the original of those tracks were totally change, there is nothing similar with what I mixed.
Please don’t tell me that I made any mistake, I checked very careful a couple days before posting this.
It is very dangerous for Mixing Engineers. I don’t know if any developer notice that? Since Cubase 10 as far as I know.
By the way I am on Macbook Pro 2019, Big Sur OS.
