Some lettering is a little worn where name of module reads: Black Digital Noise. See photo. ***The Erica Black Digital Noise is a pathological brainchild. A unique noise module that makes wide range of noise effects; almost pure white noise, Atari console-like one bit noise and other crazy, more-less predictable sounds. At the heart of the module is a programmable logic matrix that includes two linear feedback shift registers that generate polynomial noise effects. A similar noise generation scheme was used in several classical drum machines, and technology comes from techniques used in data scrambling. Features: ● Wide range of noise effects (pure white noise to 1bit & 4bit vintage computer style noises) ● Two polynomial feedback shift registers with CV control to set noise character ● Adjustable noise frequency ● External clock in - can follow frequency of VCO ● Sync feature - polynomial reset ● Can process audio signals (Even voice!) ● Inputs/outputs are protected against over-voltage ● Diode protection on reversed power supply
