ProTools - Clearing the Database

ProTools uses a complex database system to manage plug-in information. This database can become corrupt. When it does, ProTools may be unable to find the Midi Quest plug-ins.

If ProTools is unable to find Midi Quest plug-ins, one solution is to clear the database which forces ProTools to rebuild the database and find Midi Quest.

To clear the database and force a rebuild, follow these steps:

1/ Completely close ProTools

2/ Open the Finder and press Shift + Command + G to bring up the Go to Folder window

3/ Clear the main Installed AAX Plugins cache

 Paste: ~/Library/Preferences/Avid/Pro Tools/

 Delete the file named InstalledAAXPlugins

4/ Clear individual plugin caches (Required for ProTools 2023.12 or newer)

 Paste: /Users/Shared/Pro Tools/

 Delete the entire folder named AAXPlugInCache

5/ Empty your Trash and restart ProTools
