My UJAM Instruments Plug-in doesn't show up in Logic Plug-in Manager

If the UJAM Instruments plug-in doesn't show up in your plug-in manager list, you need to force Logic to rescan the plug-in folder.

Note: This triggers Logic to do a rescan of ALL of your plug-ins installed. This could take while – you might want to brew yourself a cup of coffee ;-)

How do I clear my Audio Unit (AU) cache in order to do the rescan?

1. In Finder, choose Go > Go to Folder from the menu 
2. Type ~/Library/Caches in the "Go to the folder" field
3. Press Go
4. Remove the "com.apple.audiounits.cache" file.
5. Remove the content of the "AudioUnitCache" folder
6. Restart your Mac! 

The next time you start Logic, the installed Audio Unit (AU) plug-ins will be rescanned and Logic should then restart normally. And your UJAM Instruments plug-in should be scanned successfully - Yay!

Note: Virtual Guitarist, Virtual Drummer, or Beatmaker AU plug-ins are only compatible with Logic 10 and newer, due to AUv2 plug-in format.

If that does not help, you’ll need to force your Logic to rescan.(Please note, all your instruments and effects will be rescanned)

1. In the Finder, choose Go > Go to Folder from the menu.
2. Type ~/Library/Caches in the “Go to the folder” field.
3. Press the Go button
4. Remove the “com.apple.audiounits.cache” file.
5. Remove the ~/Library/Caches/AudioUnitCache folder.
6. Restart your operating system.
   (don’t forget)

The next time you start Logic, the installed Audio Unit plug-ins will be rescanned and Logic should then startup normally. And your ujam Instrument should be scanned successfully.
