I was just thinking maybe a plugin version update might cause this too?
If the plug-in updates result in changes to the CLSIDs used in the VST inventory, then the plug-ins are different as far as SONAR is concerned. There would be no upsample settings for the new (updated) plug-ins. I have not experienced this after updating plug-ins on my system but it is possible.
Updating plugins causing the problem was hypothetical. Never actually had the problem after performing one.
I update normally, through command center. If my Audi is changing it's not from my own doings.
I restore/ backup roughly monthly, when I have new plugins verified working properly or testing betas finished. The up-sampling feature works properly throughout this phase & only changes after Plat has installs a new version. ( & not with each update)
I'll keep your compare idea in mind.
Thanks for your help & suggestions.
