There are many tutorials that show how to use SoundFonts on GarageBand. (Source)
However, when I do step 5 on this page, no dropdown menu appears (and nothing happens).
How can I install SoundFonts to GarageBand 10.2?
Best Answer
Ah yes, this is something Apple's been sent feedback about in terms of their user interface design for GarageBand 10. It's actually a quick fix that will hopefully get addressed in an upcoming update (changing the default setting on installation will probably do the trick for most people).
Using SoundFont (SF2) files in GarageBand v10
To get your SoundFont files to work in GarageBand 10, follow these steps:
Launch GarageBand and open your project
Go to GarageBand > Preferences
Select the Audio/MIDI tab
Within the Effects section, tick the Enable Audio Units checkbox
Exit Preferences
If it's not already, open the Smart Controls window
Now click on the Plug-ins drop down menu and select Instrument > AU Instruments > Apple > DLSMusicDevice > Stereo (see screenshot below):
A DSLMusicDevice window will open (this may take a little while)
Now click on the Sound Bank drop-down menu to select your SF2 file (see image below):
Once you've selected your file, close the DSLMusicDevice window
Now press commandK to open the Musical Typing keyboard (or you can just go to Window > Show Musical Typing).
Now you can play the sounds from the SoundFont (SF2) file you selected.
Installing SoundFont files on macOS
The steps above show how to use SoundFont files within GarageBand 10. However, if you want to download/install additional SoundFont files in macOS to make them available to GarageBand and other apps, follow these steps:
Download the SoundFont files you want
Within the Finder, press and hold the option key
Keep the option key down and click on Go > Library
This will open your user's Library folder (you can let go of the option key now)
Within the Library folder navigate to Audio > Sounds > Banks
Press shiftcommandN to create a new folder
Move your SoundFont (SF2) files into this folder
Now your SoundFont files will be available to any apps that support them.
Usually, we can easily import MP3 files to GarageBand (especially GarageBand 11)
However, sometimes the import process will encounter difficulty in importing an MP3 into GarageBand in two situations:
Situation 1: GarageBand only imports MP3 files which have the extension in lower case: ".mp3". If you try to import MP3 files (like MP3 recorded from the Olympus LS-10) with the extension in upper case: ".MP3", GarageBand will refuse to import those kinds of MP3 audio.
In this case, change the MP3 file extension to lower case in order to import MP3 to GarageBand.
Situation 2: GarageBand only supports those MP3 audio files which have a sample rate of 44.1 kilohertz (kHz) and a bit depth of 16 bits.
In this case, it will be necessary to convert the MP3 file(s) to GarageBand's more compatible AIFF file format.
