The only (I think relevant) Ivory component which appears in /Library/Audio/Plug-ins is actually in 'VST' (neither VST2 nor VST3; it's Ivory.vst.
Its Package doesn't seem to have a file with its GUID string.
Where would I find it, please?
Then, in my Defaults.xml file, there is nothing with the value="0" already; can I just create one with Ivory II's GUID string (assuming I can find it)?
to the vst2whitelist.txt file
