After update to Garageband 10.3.1 most midi loops are gone

Do you perhaps have an older Time Machine backup from the time you still had midi loops installed? Then try to restore the missing loops from this backup.

The loops are installed in the folder /Library/Audio/Apple Loops/

Look inside the Library folder at the top level of your system drive, some may also be in Library folder in your user home folder.

As the midi loops are needing the instruments to be installed, you may also need to recover the older instruments, that are no longer part of the newer GarageBand versions. The sound library with the instruments is installed in the folder

/Library/Application Support/GarageBand/Instrument Library/

But you may want to send feedback to Apple and explain why you want the software instrument loops back. There is a feedback form here: Apple - GarageBand - Feedback

I am also preferring the software instrument loops.

• They do not need so much storage.
• Midi loops are easy to modify and change single chords.
• They can be used for more than one instrument.
• And most of all, we can see at a glance, what the loop will play.
• I do not have to waste the time by listening to the loops.

I am rarely using the real instrument loops, because it is so hard to find any useful real instrument loops. There is no description of the chord sequence they will play, and it is difficult to edit them.

Do I only need to copy the old files into the folders you name above and re-index the library?

Yes, you copy the missing loops into the corresponding loops folder in the library, and the sounds into the corresponding folders in the Instrument library.

Then you use the command "Reindex All Loops" from the drop-down menu at the top of the Loop Browser in GarageBand.

GarageBand 10 does not have many midi loops. Most of the loops are unfortunately real instrument loops.

Did you perhaps had previously loops installed that came with the older GarageBand '11? Or with Jam Packs? GarageBand '11 and the Jam Packs came with plenty of the much more useful midi loops. You could use the old loops in GarageBand 10, if you did not uninstall them, when you upgraded to GarageBand 10. But when you now download GarageBand 10 and reinstall it, there will not be many midi loops in the loop library.

Have you checked, if a filter has been enabled for the Loop Library?

Make sure, that In the GarageBand > Preferences > Loops the option "Keyword Browsing > Filter for more relevant results" is disabled, or you will only see a subset of your loops in the Loop Browser.
