I need help, WAVS staying one note.

A freind recently gave me a cd full of sounds (all WAVS) and i just dragged them into the fruity loops folder where the other wavs are but when ever i try to change the note or change the pitch it allways stay the same, how can i make it so it changes to what ever not or pitch i put it on? thanks alot!

Edit the wavs in CoolEdit - simple as that.

In the Sampler in FLoops, un-highlight the "use loop points" light under Loop and also change the time stretching setting to "elastique - tonal". That should do it.
