[sdiy] samplers & pitch shifting

[Tim Ressel]

That was a great read. Thanks! And thanks to all who replied!

I think the delay version is the one I'll try first, mostly because it 
fits in my head ;-) The other two seem like black magic to me.

I was told things like drum samples would be worthless without pitch 
shifting. Not sure if that is true, but if I can pull it off then why not?
