Monocle (blinds)

The Monocle Polarizer by After Later Audio draws inspiration from Blinds by Mutable Instruments.

A voltage-controlled polarizer can be used for more than scaling and inverting CVs but due to its nature as a four-quadrant multiplier, it is also a VCA that not only attenuates but also inverts the signal. You might as well use it as a ring modulator!

Monocle contains two such polarizer circuits which all can generate an offset voltage, too. Each channel consists of a polarizer which, unlike a VCA inverts negative CVs instead of muting them. Per channel, there’s a signal input, a signal output, a potentiometer for setting the polarity and gain and eventually a CV input with a small polarizer for scaling the modulation.

The outputs of the four channels are cascaded and mixed from top to bottom.
