No matter what combination of output formats I check (vst, vst3, au), only 1 file is being created. I'm on OSX. I see that there is only one output target, and even if I change the settings, there is still one output target.
Any Idea on how to get it to build all 3 at once? Or are you supposed to build one at a time?
This is OK as the same bundle has different code entry points for the different plug-in formats. The build script at the end of the build will copy the target into both VST, VST3 and AU folders in the Plug-Ins folder (for me in ~/Library/Audio/Plug-Ins).
