Various Ornament & Crime

Open-source multi-app platform with quantizers, sequencers, and generators

12 HP Eurorack module

Ornament & Crime is an open-source multi-function module based on a Teensy microcontroller. It runs multiple "apps" selectable at runtime, including quantizers (CopierMaschine, Quantermain), Turing Machine emulations, step sequencers (Sequins), envelope generators (Piqued), Lorenz attractors, and more. Each app repurposes the 4 CV outputs, 4 CV inputs, 2 digital inputs, and 2 encoders differently, making it one of the most versatile modules in Eurorack.

Features

  • 4 CV outputs (DAC, 16-bit)
  • 4 CV inputs
  • 2 digital inputs (trigger/gate)
  • 2 rotary encoders for navigation and parameter editing
  • OLED display for app selection and parameter display
  • USB port for firmware updates
  • Open-source with active community firmware (Hemisphere Suite)
  • Runtime app switching without power cycling
  • Scales and settings saved to EEPROM
