Hi dathho,

Thank you for reporting the issue with VST3 plugins in BIAB. I’d like to gather more details to troubleshoot this effectively:

Are you trying to add a VST3 plugin to an audio track or a MIDI track?
Keep in mind that in BIAB:
Audio tracks only support FX plugins.
MIDI tracks only support instrument plugins.
If you’re not seeing your instrument plugins in the VST3 list, it might be because you’re working with an audio track instead of a MIDI track.

Does BIAB crash when scanning a specific plugin, or does it fail to scan any VST3 plugin on your computer?
If it’s a specific plugin causing the crash, which one is it?

As a test, could you temporarily remove the problematic plugin(s) from the VST3 folder and try rescanning? This will help us determine if the crash is plugin-specific or a broader issue.

You mentioned that Halion Sonic appears in the list but crashes when loaded. Can you confirm if this happens consistently or only under specific circumstances?

Once we have more details, we’ll work on getting this resolved for you. Thanks for your patience!
