OK I will try to explain why I was asking - perhaps it will make sense, sorry for any confusion.
Yes, I know Sonar will scan whatever you tell it to, as far as paths in the search list. I was trying to figure out if you were scanning a bunch of extra stuff, PRECISELY because Sonar will scan whatever you provide it. I was thinking that you may have had all kinds of 32-bit plugins being scanned, even though you might not be using them in x64 Sonar, and I was also wondering if you had some PARENT folder that was telling it to scan like maybe your whole C:\Program Files folder or anything like that.
I also had earlier tried to explain why a lot of plugins, like Kontakt, get listed multiple times. I will try again - sorry for any confusion there too. Lots of plugins have multiple ways of being loaded, and because of this, a single plugin (like Kontakt) will have multiple listings, even though it is the same program. It shows up multiple times because it allows you to load in one of 3 ways: a version with 8 available audio outputs, a version with 16 available audio outputs, and a version with 64 available audio outputs. This is why I had suggested you edit the names in Plugin Manager, so that you could tell the different versions apart when you are trying to insert a plugin. If you need that post again, please let me know and I will post back with the exact post I included those steps in.
I rarely use 32-bit Sonar, BUT because I created a sub-folder within my 32-bit plugins main folder to contain the ones I want to use in both x32 and x64 Sonar, it all works well and all of the intended 32-bit plugins show up as intended for each version of Sonar.
My main 32-bit plugins folder is:
C:\Program Files (x86)\VSTPlugins
The SUB-folder I created within that for 32-bit plugins I want to use in x64 Sonar is:
C:\Program Files (x86)\VSTPlugins\Approved for x64
Since Sonar scans all sub-folders within the folder you put in the search path, ALL 32-bit plugins are detected by x32 Sonar by just including the C:\Program Files (x86)\VSTPlugins path, as it will know to also look in the 'Approved for x64' sub-folder.
I ONLY add the C:\Program Files (x86)\VSTPlugins\Approved for x64 path to x64 Sonar's search path to pick up ONLY the 32-bit plugins I have made sure work in 64-bit Sonar, and no other 32-bit plugins are then detected by the x64 Sonar's VST scan.
