Noise Rainbow Analog / Digital Pseudorandom Pulse Generator

ARC Noise Rainbow

The Noise Rainbow is a source of analogue noise and digital pseudorandom pulses. Both sources are generated by new old stock Soviet components (KГ401 and К176ИР10).

The Analogue Noise submodule provides white, grey and coloured noise. The colour output is continuously variable between red, blue and violet for tailored noise.

The Digital Noise submodule produces digital noise that can be swept down to a low frequency random pulse train. The rate can be voltage controlled, or externally clocked to extend the range into a digital VCO reminiscent of chiptune sounds.
