Mutable Instruments today introduced two new Eurorack module designs, Blinds & Veils.

• Veils is a quad VCA with adjustable response curve.
• Blinds is a quad VC-Polarizer (aka four quadrant multiplier or ring modulator – a VCA that flips the sign of the signal when it receives negative CVs).

Blinds is a 4-channel voltage-controlled signal polarizer. Each channel consists of a polarizer circuit, also known as a four-quadrant multiplier. This circuit acts like a VCA, except that a negative control voltage will cause the output signal to be inverted, instead of being silenced. Blinds’ outputs are daisy-chained, allowing adjacent groups of 2, 3, or all 4 channels, to be mixed together.

One can think of Blinds’ as a voltage-controlled version of Shades, the control center for all the modulation CVs used in a patch.

Many other uses are possible, though. For example, each individual channel can be used to scale/offset a CV; and with audio rate modulation signals, each channel acts like a ring-modulator, with massive potential for drones and feedback patches.

Veils provides four VCAs with an adjustable response curve.

Veils’ outputs are daisy-chained, allowing adjacent groups of 2, 3, or all 4 channels, to be mixed together.

Each of the VCAs can be used for shaping the amplitude or timbre of a tone with an envelope, animating a mixture of several oscillators, controlling the amount of filter modulation with a random source or a touch controller or applying an envelope on the linear FM signal hitting an oscillator.
