    - Feedback: Amount of transposed signal fed back into the harmonizers (feedback is voice independent).
    - Harm1/Harm2: Mix between the first and the second harmonized voices.
    - Dry/Wet: Mix between the original signal and the harmonized signals.

    - Win Size Voice 2: Window size of the first harmonizer for delay (1, 0.75, 0.5, 0.25, 0.2, 0.15, 0.1, 0.05 or 0.025).
    - # of Polyphony: Number of voices played simultaneously (polyphony); only available at initialization time.
