Replacing the cross modulation control of the legendary Soviet era Polivoks analogue synthesiser, this control will provide the user with the ability to set the duty cycle of the pulse wave of one oscillator. The control will set the duty cycle at any point between 10% and 90% and has a neat trick of a pull switch that will then modulate the pulse width with any of the Polivoks modulator wave shapes.
