Where are the musical instrument loops in Soundtrack Pro 2 audio content?

I just installed Soundtrack Pro 2 and 21.12 GB of audio content that came w/ it but I can't find any musical instrument loops whatsoever when I search the contents from the application. The folder is indexed but all that shows up is sound effects. There is no means to create a musical track. Even when I click on the folder itself on the drive where it's stored, I don't see any musical instrument files like I do w/ Soundtrack v1.5 (which I can still access). This can't be right and I don't have a clue as to what I did wrong.
