ChowDSP Poly Octave

A polyphonic octave shifting effect. Poly Octave is an effect that will generate multiple copies of the incoming signal, pitch shifted up or down one octave. The effect uses a phase-scaling pitch-shifting technique which allows it to correctly shift a polyphonic input signal. The three controls on the effect control the output volume of each copy of the signal; the Dry, -1 octave, and +1 octave signals.
