Erica Synths Black Digital Noise Eurorack Module
Eurorack Noise Module
The Black Digital Noise is our 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 or 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.
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
Similar noise generation scheme was used in several classical drum machines, and technology comes from techniques used in data scrambling.
