Thanks much, well I still simply could not find it anywhere at all,. so decided to upgrade to the latest version I see online:
Sonar Home Studio 23.9.0 BUILD 32 [2017.09] - x64 (which curiously, can only be accessed as a demo - I am unable to find anywhere how I can authorize/upgrade ...???)
anyhow, in Preferences itself, I see the file I am looking for under the tab File/VST Settings, but I cannot hear any VST sounds in any *wrk piece I load .. or find out how/where I can configure the sounds to be available?
I have ARIA Player fully installed and usable w/Finale, how can I get Sonar to "see" these sounds?
gulp looked everywhere ... any advice is greatly appreciated.
