Sample Magic loops and such etc.

Trying to find out how to use some of the loops and samples included with Sonar X1 but not finding much. I found there were two copies of Sample Magic in in the Audio Library Folder. In the "Loops" /Sample Magic/Around The World In 80 Raves folder there were 33 .rx2 files. In the "One Shot" /Sample Magic/Around The World In 80 Raves folder there were only four .wav files. This was confusing if the browser was not in the right folder. Also as I import one of these "Sample Magic" .rx2 files on two a track is there a way of changing pitch or anything else to follow a chord progression. Or using them other then way. Just didn't find much on You Tube or any where else.
Thanks for any help, Will
