Cant figure out how to load any samples...

Hey I can load my recorded samples on the iPad. But paying the extra 2 dollars I dont see how to load all the other samples. I would think that clicking on the button to launch the sound would list the sound packs that list as installed? I bought this app as the newest version and nothing is listed. Whats the deal with that? Can you tell me how to play the actual sound packs?

Please, thank you.
