Dreadbox Dystopia
Chaotic noise engine and probabilistic signal mangler
10 HP Eurorack module
Dystopia is a Dreadbox noise-crush-filter module that combines bit-crushing, sample rate reduction, and dual colored noise generators (pink and blue) with independent filters. It can process external audio or generate its own noise textures with CV control over all parameters.
Features
- Internal white noise generator cancelled by external input
- ODDS control sets probability of gate/scatter events (0-5V output)
- BITS control sets bit crush clock frequency
- Pink noise output with filter roll off control (sends +/-5V)
- Blue noise output with filter roll off control (sends +/-5V)
- SCATTER output passes high-odds noise events at +/-5V
- CRUSH output sends bit-crushed noise at +/-5V
- EXT IN accepts +/-5V signals
- In external mode: SCATTER becomes negative voltage slicer
- In external mode: ODDS Out becomes distortion with BITS as frequency control
- In external mode: CRUSH becomes bit crusher
- In external mode: PINK Out becomes 12dB/oct low pass filter
