Pitch & BPM

Is there a way to raise the pitch of my sample without changing the bpm... for example I want to use a vocal part of the same sample source, but make it sound a lot higher pitch... Kanye West does this a lot... is what I am asking possible? Thanks!

you would have to time stretch the samplpe so it matches, or you could get the fantom-s or the vp9000 they have "variphrase" technology, and thats what you want.

Thanks... Is there any software that can help me with this? ALso what if I double the BPM and then time strech?

just to let you know from my experiences....kanye west most probably changes the tune of the sample but layers it over the instrumental....thats mainly how he changes the "pitch"...he definitely does thi son a lot of songs but it may not be the ones your talking about...so i may be wrong...just tryin to help
