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):

5/11/15 12:37:27.595 PM MIDIServer[5093]: 12:37:27.594 NOTE:      [0x7fff75d32310] MIDIServer.cpp:353: FullInit: MIDIServer [5093] starting; arch=x86_64

5/11/15 12:37:31.447 PM GarageBand[5082]: Invalid color System, labelColor (warning given only once)

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

Interface types explained (VST, RTAS, AU, etc.)

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

    They are all AU plugins, in the component folder. – Marcin May 9 '15 at 17:43
  • afaik, both Synth1 & TAL-Bassline are only available as VSTi. Do they have a .component extension, or .vst or…? – Tetsujin May 9 '15 at 17:53

    Yes, they have a component extension just as I say in my question. – Marcin May 9 '15 at 17:54
  • Then it would be interesting to know where they came from… see kvraudio.com/product/synth1-by-ichiro-toda and kunz.corrupt.ch/products/tal-bassline – Tetsujin May 9 '15 at 17:55
