SOUND LINKAGE IN LIBRARY

¤   Presumably you downloaded the zip file mentioned above, and now have all 13 notes unzipped and stored somewhere on your machine.
¤   The next step is to import these 13 files to Library [ File | Import to Library ].   You may import all 13 sounds at once.
¤   Sounds will remain in the Library, but instead of being referred to by filename; such as c3.wav, they are given a Linkage Name; such as c3.

¤   Right-click on a sound file in the Library, then select Linkage.
