Missing loops in GarageBand
I am using the most recent version of GarageBand (10.0.3). In the loop browser, there is, for example, Orchestra Strings 18, then Orchestra Strings 25, then Orchestra Strings 27, then Orchestra Strings 79 (skipping all the loops in between). Where can I find these missing loops along with any others? Thanks.
