Frequently Asked Questions

Does Patch Bay require restarting audio apps when routing?

No. Patch Bay uses native macOS process tap capture so you can tap audio from running applications without interrupting playback, and route through the virtual audio driver into your DAW or broadcast software.

Can I run VST3 and AU plugins on system or app audio?

Yes. Patch Bay includes an integrated VST3 and Audio Unit (AU) scanner and host, allowing you to insert VST3 and AU effects directly between any audio source and output destination.
