I went all in with Sound Forge Pro 12 and got the Suite. I was surprised to see that it installed the included VSTs (essentialFX Suite, Analogue Modelling Suite, etc.) into a Magix plugins folder inside the Sound Forge folder.
For VST2, files, they should be installed in the user's VST folder. In addition, you are almost always given the option to specify the folder. I don't believe the Sound Forge installer gives those options. I have already committed to two other directories for VSTs and Sound Forge only allows for two directories in its preferences?!
So, ironically, the only place I can use the Magix plugins are my other audio apps (if I'm willing to add the Magix plugins directory to their list of scanned directories). I can't access them with Sound Forge unless I'm willing to do something ugly like copy the entire Magix plugins directory to my VST folder.
Uggh...any better workarounds?
