What I see on your YouTube clip is ‘‘the best’’ that may happen in my case (playback working, but GUI freezed…). In many projects, it simply won’t even launch the project and CP8 is barely opening the splash screen and as soon as I select a project to open, it disappear (I get a click on my Yamaha mixing board and nothing visual on screen). Can’t even shut CP8 normally (just by FORCE QUIT as I wrote above…)
I went through the typical ‘‘disable preferences’’ but it changes nothing. I even went the hard way and through Library / Preferences and renamed Cubase folder as ‘‘Old Cubase’’ - it didn’t solve anything except I will now need to redo all my settings for audio and midi interfaces and defining external MIDI modules… !!!.. I’m justfed up with Cubase for now to try anything else. (Guess the next step might be to uninstall everything and just redo from scratch and stop update to 8.0.20… But that won’t be in coming days, I don’t have time to waste on this now and will just work with working DAWs.
Please let me know if you encounter a solution (we still have some similarities - partly at least)
