On occasion, Logic Pro X and higher does not show the VocALign Pro, VocALign Project, VocAlign Ultra or Revoice Pro Audio Units plug-ins after installation.
Please try the following steps:
Go to the folder
Delete the file
Empty the Trash
Reboot the computer (We think this is important to fully clear the cache)
Launch Logic Pro again
VERY IMPORTANT – PLEASE READ:
The file you want to delete - com.apple.audiounits.cache - is in a hidden folder.
Browsing or a search will not locate it.
There are 2 ways to reach the correct Library folder:
In the Finder, you need to choose Go > Go to Folder…
then, in the window that will appear (please see the image below)
you need to paste EXACTLY this location, with all its characters: ~/Library/Caches/AudioUnitCache
Once again: ALL THESE CHARACTERS: ~/Library/Caches/AudioUnitCache
You must then delete "com.apple.audiounits.cache"
then empty the trash
and (very important!) reboot your Mac.
Click on the "Go" menu in the Finder, hold the "alt" key on your Mac keyboard and watch for the "Library" entry to appear between "Home" and "Computer" - that is the Library folder you want, so click on it, then navigate to Caches > AudioUnitCache, where you will find "com.apple.audiounits.cache" that you need to delete.
Then you need to empty the trash can and (very important!) reboot your Mac.
