Cubase 12 scans all plugins on startup. Every time. And it takes ages

Hiya. Running C12 on W10. I’ve had some problems with it crashing on startup, but the latest upgrade seems to have solved that.


It now runs a complete plugin scan EVERY TIME I start it up. Takes anywhere up to 25 minutes . This feels fairly ridiculous for a professional product. C11 is still rock-solid and starts up fairly immediately.

Anybody have any ideas on what I might be doing wrong?

I think it could be a plugin that is changing something in the VST2 folders on exit.
So Cubase thinks it needs to scan the VST2 folders.
But of course, it’s just an idea.

That would maybe make sense, I think.

Do you use any Waves plugins?

I do. Puigtec, Abbey Road Chambers, Vinyl and TG Mastering, Butch Vig and Scheps channel strips and maybe one or two others.

You can try temporarily removing the Waveshells. If this solves the issue then use this (make a batch file).

Note this just stops the local server, deletes it and deletes caches. All are recreated next time you start.

taskkill /f /im WavesLocalServer.exe
timeout /t 1 /nobreak
rmdir /s /q "%LOCALAPPDATA%\Waves Audio\Waves Local Server"
rmdir /s /q "%APPDATA%\Waves Audio\Caches"

Thanks! I’ll give it a go!

Don’t forget to remove all Waveshells. From VST3 and VST2 locations. Worth a try and you can always move them back if it makes no difference.

Make sure your plugins are up to date, and if you run any kind of system disk cleanup or maintenance tools disable them and try.

Basically anything that could cause a modification in the plugin folders can be a culprit.
