There are several threads with this issue but no solutions.
Very often when I use Groove Agent and preview the kits, the program freezes in a playback loop. The pattern continues playing forever and there is no way to stop it. I have to use the Task Manager to get Cubase to stop, but of course I lose all unsaved progress if I do this. Please Steinberg, I am a Cubase 11 Pro user - we deserve a proper solution to this very irritating issue.
