Upon rereading the page that seems incorrect on my part. None the less, we would still require a way to do pitch detection on the original vocal signal to know how far we are attemtping to shift, I believe. It's also unclear from this write up how little you can shift a signal. Does the pitch shift input support shifting down to a few cents? Cheers, Mark
