most sample based machines I know just transpose the sample up and down. 
length changes. just like a tape machine.
to keep the sample the same length the most common are granular 
approaches (OLA PSOLA etc) or FFT based shifters.

I only know the bode frequency shifter, but thats a whole other effect 
as the harmonic distribution does not stay intact (metallic sound)
