Thank you again. Very useful links.
My Diva was installed only as VST3 so there were no NKS options, but I installed the VST2 version and converted all my presets to NKS. (VST3 version still works fine).
I didn't realize that Komplete Kontrol can't work with VST3. But they will follow I think, VST2 is history in 2020.
I leave it as it is - NI's stuff and VST2 will be managed in Komplete Kontrol and the minority of not detected instruments are managed as track templates in the DAW.
