Need more overview in your PlugIns? Here is what I found out about:
Cubase PlugIn sorting
I don't know why Steinberg makes such a magic about PlugIn-sorting (Maybe they want to create reasons to sell it in Cubase 8?). It is easy to manage yet in Cubase 7 /7.5! So this one goes for VST2 Plugins...
1. Create in your VstPlugins Directory Subdirectories like:
2. Any VST2 PlugIn you install directly in those subdirectories will be sorted correctly!
Install for example "Audio Damage Kombinat" into the directory C:\Program Files\Vstplugins\Distortion
and it will be correctly sortet near by the Steinberg Distortion Plugins!
If you create a further subdirectory like ..\Vstplugins\Distortion\AudioDamage you have all Distortion Plugins from Audio Damage in one folder, right under the Distortion Group
