(I am running Windows 7.)
Per scook's suggestion, I made sure that the scan paths were correct. I found that there was a duplicate in which a subfolder of another scanpath also specified, presumably causing some plugins to be scanned and counted twice. After removal of the subfolder from the scanpaths, the quantity of plugins found on startup was reduced from 290 to 256.
Using the Plugin Manager, I added together the each of the three plugin status categories, resulting in the following totals:
enabled plugins: 176
excluded plugins: 48
permanently excluded plugins: 78
Therefore:
176 (enabled plugins) + 48 (excluded plugins) + 78 (permanently excluded plugins) = 302 (total does not make sense to me)
Similarly:
176 (enabled plugins) + 78 (permanently excluded plugins) = 254 (closer to what the Sonar scan finds)
Questions:
1) Which of the plugins (enabled, excluded, permanently excluded) are included in the Sonar VST scan total?
2) What is the difference between "excluded" and "permanently excluded" plugins? (I believe, from the documentation, that "permanently excluded" plugins have been completely removed from the system, including registry entries. Therefore, how can they possibly be included in the scan total?)
3) How can I completely remove a plugin from the system? Is it simply a matter of deleting the .dll in file explorer?
4) How can I exclude a plugin from the startup scan?
5) Is there any benefit to excluding VST's other than removing clutter from the Plugin Manager and plugin insertion operations?
I know that I can ignore the numbers and just happily make music. However, I am wondering whether this issue is trying to tell me something, possibly having to do with why it takes so long for me to invoke Sonar and to open some projects.
