Ah, and how do these artifacts sound? I'd love to hear this effect.
BTW, pitch changes do not produce any artifacts? Only speed changes?

I currently use an Emu sampler for the slowdown effect, and it does
a beautiful job at that. I was hoping the the Repeater could provide
me with a more real-time interface for the same trick.
