Enable Audio Plug-Ins in Premiere Pro

Premiere Pro may require additional steps to load any newly-installed Audio plugins on the system.

Bring up the Audio... section of its Settings window:

Click the Manage Audio Plug-Ins button:

Click the Scan for Plug-Ins button to ask Premiere Pro to load any new plugins from the appropriate locations on disk:

Once the process is complete, and newly installed plug-ins should be enabled by default. You can make sure all plug-ins are active by clicking the Enable All button.

The availability of individual plug-ins may be controlled via the checkbox that appears next to each plug-in detected on disk.

Note that some plug-ins may be available through more than one technology, such as VST3 and Audio Units.
