1uO_c – 4ROBOTS is 1U Ornament and Crime for Intellijel 1U format.

The first Ornament and Crime with VOR System

Ornament and Crime is the “Swiss army knife” for your system, now for Intellijel 1u format.

Multi-purpose module with tons of functions:

  • Analogue shift register
  • Tonnetz transformations
  • “vector” sequencer
  • Quad pitch quantiser
  • Scale and note mask sequencer
  • Quadrature LFO
  • Lorenz and Rössler
  • Quad envelope generator
  • Step sequencer
  • Bouncing ball envelope generator
  • Byte beats
  • Harmonic quantiser
  • Reference voltages
  • Frequency meter
  • Tempo meter


VOR – Variable Outputs Range:

Previous versions of Ornament and Crime modules can only offer output range of 9vpp and single offset (usually -3v to 6v). To change this offset, physical resistors at the circuit board should be replaced with different values followed by long calibration process.

This range is a compromise for most o_C applications, it is not good enough for envelopes which needs a peak of 10v to completely open a VCA and it’s not good enough for a LFO’s which needs a Bi-Polar range for its operation.


At the development process of 1uO_c 4ROBOTS we decided to completely redesign the range and offset system (at the hardware and at the firmware) to achieve variable range that set automatically for each App*.

1uO_c 4ROBOTS comes with extended range of 10vpp and option to set the range to: Bi-Polar (+/-5v), Uni-Polar (0v to 10v) or semi Bi-Polar (-3v to 7v)*.
** Not compatible with Pulp Logic 1U.
