the red font is Cubase’s way to tell you that you have manually reactivated the plugin
after it was blocked by Cubase. It’s just a warning. To get rid of this, you need to
initiate a plugin rescan.
You can do this by deleting the VST3 plugin cache.
First quit Cubase. Then open a Microsoft Explorer window and navigate to the following
location:
C:\Users\YourUserName\AppData\Roaming\Steinberg\Cubase 13_64
The AppData folder might be invisible, so you might first have to switch Explorer to
display hidden folders.
To do this, click the View tab in the menu bar of Explorer and activate the “Hidden items”
option.
Inside of that “Cubase 13_64” folder you will find a “Cubase Pro VST3 Cache” folder.
Delete that Cache folder.
Now start Cubase and it will perform a new VST3 plugin scan.
If you installed the Diva beta from KVR, Cubase will now correctly scan the plugin and it
won’t appear marked in red anymore.
