The plugins don't scale properly when using HiDPI monitors (at least in Cubase with the HiDPI setting on). This is just RIDICULOUS. I saw another post where you blame Steinberg, but this is the ONLY vendor with this problem. NI, UAD, VSL, East West, SoundToys, Softube, etc. NO ONE BUT ARTURIA has this problem.
I now -really- regret upgrading.
