It is possible that the plug-in has not been scanned correctly.

To force a re-scan of the plug-in, do the following:

• Go to Logic Menu and go to Preferences > Audio Units Manager.

• Click Reset & Rescan Selection.

• If problems persist, quit Logic.

• Go to HD/Users/'Your Account'/Library/Caches/AudioUnitCache In that folder, delete the file called "com.apple.audiounits.cache".

• Restart Logic. It will re-scan all the available plug-ins, then the plug-in should now show up in the list.

If you do not see the "User Library" folder, you may open this path in a new window by clicking Go > Go to folder... in 'Finder' (the shortcut is SHIFT+CMD+G), and type in the address in the window. Or...

Open Terminal in your Applicatiosn/Utilities folder and type the following command, enter your system password and press the Enter key. This will show the folder permanatly.
