Ornament and Crime is the "Swiss army knife" for your system, now for Intellijel 1u format.
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 peek 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. 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 Asymmetric (-3v to 7v)*.
Expander header is available on 1uO_c 4ROBOTS v2.0 back. 4ROBOTS series is made according to the Intellijel 1u standard and will fit all Intellijel cases with a 1u row
