Mutable Instruments Blinds is a VCA module for modular synthesizers in Eurorack format. Blinds add a four-channel VC signal polarizer to the modular system. The individual channels consist of a polarization circuit, also known as a four-quadrant multiplier. This circuit behaves like a VCA, with the exception that a negative control voltage inverts the output signal instead of silencing it, but other applications are also possible. The outputs of the module are daisy-chained so that adjacent channels can be mixed.
Further applications
Each channel of the Mutable Instruments Blind can be used to scale / offset a control voltage. With audio rate modulation signals, each channel acts like a ring modulator with massive potential for drones and feedback patches.
