The Noise Rainbow is a source of analogue noise and digital pseudorandom pulses. The Analogue Noise submodule provides white, grey and coloured noise. The colour output is continuo usly variable between red, blue and violet for tailored noise. NOS Soviet era noise diode KГ401 provides the analogue 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. For v1.1 the noise diode is now on a socket which allows for experimentation with other transistors and diodes for noise characteristics. KГ401 was chosen for loudness and noise spectrum.
