VST3 Host: plugin crash while scanning (BundleEntry/BundleExit)


I’m working on a VST3 Host and I have an issue with scanning some plugins.
I’m scanning the plugins in a separate thread, and some plugins that display a login UI or some sort of heavy initialization are crashing when I call the BundleEntry (Waves…) or BundleExit (SSL Dumpstrip…) functions.
This happens in both Windows and MacOS.


You need to init plug-ins on the main thread. Best to prevent crashes is to use a helper app you call which does the first scan.

Thanks for the quick reply @Arne_Scheffler. Ok I will try that and see if it helps.
