3rd Party Sampler libraries have disappeared

All of my 3rd party sample libraries for the Logic Sampler (formerly EXS 24) have disappeared. Help! (Apple Studio M1 Max, Tahoe 26.4.1, Logic 12.3)

If you have upgraded to Logic Pro 12 from Logic Pro 11 or earlier, then you may need to reinstall your third-party sampler libraries. LP12 completely reworks the library framework and files storage locations.


From Google AI:

❝ Logic Pro 12 features a consolidated sound library that bundles all patches, samples, and Apple Loops into a single Logic Pro Library.bundle file located in your Music folder. This update introduces a visual shopfront interface for managing, previewing, and downloading artist, producer, and instrument sound packs.❞


Touch base with the developers of your third-party libraries for their guidance.
