Ulf, I think what SoundGuyChris is trying to do is explicitly blacklist all plug-ins apart from Kontakt. I’m not sure how that might be done. It might be possible, perhaps, by editing the file Vst2xPlugin Blacklist VSTAudioEngine3.xml, which you’ll find in %APPDATA%\Steinberg\VSTAudioEngine3_64, but I don’t know what syntax you would need to employ.
