Installed update 7, (x86 only FORTUNATELY!), and Sonar can't "find" my Slate and Lexicon Plugs.
HUH?
Pulled up Sonar x64 (update 5 mind you), Slate and Lexicon are there in Plugin Mgr; they work just fine!
Ran VST Scan, I'm demoing the MMelda Convolution thing, and Slate and Lexicon are STILL THERE; work just fine.
Running "vst scan" with "re-scan failed plugs" and "re-scan existing plugs" in x86 saved the day!
TIA,
Tom
