Plug-ins Can't Access Sounds


Some or all plug-ins loaded by the Audio Engine can't seem to be able to load sounds, presets and other contents.


With macOS Big Sur and later, programs are required to ask the user for permission to access external volumes and other folders. Some audio plug-ins are not aware of this when they attempt to open their sounds and presets. Unless the Audio Engine has been granted permission, the plug-ins it has loaded don't have that permission either.


  1. Open Audio/MIDI Setup and visit the Audio tab.
  2. Select the Audio Engine that is unable to load sounds, if necessary.
  3. Click on Grant File Permission.
  4. Point the file dialog to a volume or folder where the sound s are stored.
  5. Reload the rack with the problematic plug-ins, or restart Synfire.
