So ive ben using fl studios 8 since it came out, havent played alot with every single setting/adjustment/ect, but ive ben using it to make "rap" instrumentals.

Anyone who has experience with the program (any version, theyr pretty much all the same), can someone tell me how to change the tempo speed of a sound sample without it changing the "pitch" of the sample also. I cant find info on google or forums. Im trying to actually mash a song for my first time, using vocals from "God's Gonna Cut You Down" by Johnny Cash, but its pissing me off that the vocals are changing pitch when i try to adjust the tempo of the sample :(
