Bug Report: cubase 9.5.40 Plugin bypass doesn't really work

Cubase 9.5.40, the yellow bypass button does nothing… This has happened to me on multiple plugins. they were 3rd party plugins , 2 for example were
waves API 560 compressor
and Voxengo SPAN

It pretty much happens on any plugin. bypass does nothing, and on SPAN you can even see its still working. only the “off” button actually turns it off, but this one introduces a small stop so thats inconvenient.

This bug did not exist in 9.5.30

Also the software crashes a lot when just loading a project… sometimes just closes without even any error message. then when opening it again and openning the same project everything works fine…that’s weird…

I hope you fix those, thanks :slight_smile:


I don’t have the plug-ins you mentioned. But with all Steinberg internal plug-ins, the Bypass button works as expected. Same with the Voxengo CurveEQ. Could you try in Cubase Safe Start Mode, please?
