Ok so I'm fairly new to using samples in my songs but I know how to go about the cutting and such. My main problem is how do I fit a sample to my already written song without changing the pitch but making the tempo fit my song. Let's say the sample is a tempo of 120bpm and my song is at 140bpm is there a way to match tempo without it messing with the pitch of the sample? Also is there any sites out there that offer vocal samples to use in a song for free? Any help at all with all this will be greatly appreciated thanks!
