I personally have tried a number of values for this parameter, and have
found that it will accept a value from 0 (default) up to but not
including 1; however, I (and others) were unable to hear a difference no
matter what value was entered. Does this damn thing work or not? I
personally love pvoc for the time stretching effect, but am quite
disappointed in the pitch shifting aspect. Anybody with some technical
knowledge on this have any answers/comments.
