What is left to try? Is there deeper Wavelab residue that needs to be deleted? it didn’t show 3/4ths of the Waves plugs, then ran the Wavelab 9.5.50 update, and there was no change. Uninstall then reinstall Wavelab 9.5.15.Trash Preferences Delete C>users>user name> app data>Wavelab pro 9.5.I then deleted everything in Steinberg>Wavelab>9.5>Cache Hold control > Force Plug-in Detection at next launch.(in the past week probably 100 times trying different things) Force Plug-in Detection at next launch.I also attached the Waves plug-ins that do show up. I’m advised to not move either locations of Waves Waveshells.

These paths are reflected in the list “on start up the following folders were searched…” The “scan on next start-up” doesn’t change anything. I attached 2 Waveshells to show their locations. It omits about 3/4s of all Waves programs. While, when scanning, I can see Wavelab scan the Waveshell, it simply doesn’t scan all Waves programs. Therefore I can conclude this is not a problem with Waves, but with Wavelab. In Cubase 10.5, Cubase locates every plug-in including all Waves plug-ins.
