A compact and slim analog noise module featuring many colors - super useful for generating textures and percussion, and the additional colors give more interesting distributions when paired with a sample and hold for use as a random source!

Analog noise provides a greater sense of depth than digital noise, creating a sort of cloud like effect.  

This new version of the Quantum Rainbow features a smaller 4hp width and two new noise outputs. All the original colors: White, Pink, Red, Blue and Purple plus the new GREY noise and QUANTA outputs.

The Grey noise spectrum exhibits a notch type frequency response in order to bring up the amplitude of bass and hi end frequencies. Grey noise sounds like a flat amplitude across the spectrum due to the logarithmic fashion in which we hear volume and frequency changes.

Quanta is a granular noise made up of equal amplitude fast triggers (quantum). Together, these random triggers (quanta) create the granular textural noise. The density of this output is adjustable via a trim pot on the back of the module.

When the original QR was first available, stackcables were not as abundant as they are today - hence the dual outputs are removed on the QR2 to save space.
