In the manual for Octavox, it says: “Each voice has its own feedback loop that causes its own output to feed back into the input. It works best with some amount of delay and can create the popular staircase pitch effects when a semitone or more or shift is applied to the voice.”
Unless I am mistaken, the bolded is not true — that in fact, it is simply a repeated delay of the pitched signal, not a pitched signal that is repeatedly fed back into itself and, hence, repeatedly pitched up or down.
Am I wrong? Or am I doing something wrong?
