I have three plugins installed in /Library/Audio/Plug-Ins/Components however Garageband only finds the first one I installed, Crystal. The others, Synth1 and TAL-Bassline are ignored, even when I restart Garageband. Crystal works fine, and is available.
Has anyone else come across this? What should I do?
I have Garageband 10.0.3 running on OSX 10.9.5. All plugins are AU (.component) plugins.
Update: This is the what shows up in console when Garageband starts up (this is all of it; there's no filter):

What plugin-type are they?
GarageBand will only use AU plugins, with a .component extension, it can't use VST etc.
Each plugin type ought to be in its correct sub-folder - Components, Digidesign, HAL, VST etc

You can force the AU cache to rebuild by deleting the cache file in
~/Library/Caches/com.apple.audiounits.cachewhile GarageBand is not running, then launch it again
