A darling of the DIY Eurorack community, the Ornament and Crime is an INSANE module for your Eurorack system. This module was soldered, tested and professionally calibrated by a pro and confirmed working.
Panel from modularaddict.com and with all DIY parts. Please email with questions before purchasing if there are any concerns! Remember that this is a DIY module project, so it won't have the same professional quality one can expect from a Mutable Instruments or Make Noise.

Ornaments & Crimes is a collaborative open-source project by Patrick Dowling (aka pld), mxmxmx and Tim Churches (aka bennelong.bicyclist). It (considerably) extends the original firmware for the Ornament & Crime (O+C) DIY eurorack module, designed by mxmxmx.
There is still a quantising ASR (analogue shift register) function in Ornaments & Crimes, now named CopierMaschine, but several other "apps" have been added. These apps are selectable on-the-fly, without having to reboot the module or toggle the power. Several of these apps are experimental, or perhaps, quirky, in nature, which is not an accident: O+C makes an ideal platform for (relatively) quickly prototyping of ideas and testing them in the eurorack modular synth context. That said, none of the apps are intended to be just toys, and some provide cutting-edge performance and/or capabilities not currently found in any other eurorack module.
The O+C module, and the Ornaments & Crimes firmware for it, also break new ground as a polymorphic module: a generic set of inputs and outputs are provided, and the textual OLED display is used to permit re-mapping of these inputs and outputs for each app, and in some cases, for each of the four channels within each app. Further refinement of this polymorphic design pattern is planned. Hard-wired, analogue modules are necessarily single-purpose, but the same is not true of digital modules, in the same way that (say) a modern smartphone can be used for a great deal more than just telephony. We believe that a single, somewhat generic module can serve as an adequate platform for many different purposes and functions. The O+C module does not purport to be the paradigmatic pinnacle of polymorphism - in fact, it was originally designed to fulfil just one purpose (= ASR) - but together with the Ornaments & Crimes firmware suite for it, we hope it provides an interesting and useful early step in the evolution of such multi-purpose modules.
The TL;DR version of this documentation: qual, in Seattle, has kindly assembled a very useful "cheat sheet" containing a condensed version of this documentation, available here.
The apps currently available in Ornaments & Crimes are:
CopierMaschine is an enhanced version of the original quantising digital emulation of a four stage analogue shift register (ASR). Harrington 1200 provides basic neo-Riemannian Tonnetz transformations of triadic chords, triggered by the digital (gate/trigger) inputs. Automatonnetz combines Tonnetz transforms with a "vector" sequencer - it can be both a chord sequencer and a melody sequencer, but not of the usual kind. Quantermain is a quad pitch quantiser for external voltages, with editable scales; it can do clocked (trigger-driven) quantising, or continuous quantising, with a latency of under 100 microseconds; it also features quad Turing Machines, May-Verhulst logistic maps or byte beats as optional, semi-random, internally generated CV sources. Quadraturia is a wavetable quadrature LFO, based on the "Easter egg" in the Mutable Instruments Frames module. Low-rents is a dual Lorenz and Rössler (strange attractor) modulation generator, partially based on the "Easter egg" in the Mutable Instruments Streams module. Piqued is a quad voltage-controlled envelope generator, based on envelope generator code from the Mutable Instruments Peaks module, but extending it with voltage control, additional envelope types, including re-triggering (looping) envelopes, additional segment shapes, adjustable trigger delays, and a unique Euclidean "trigger filter" which turns the app into a Euclidean rhythm generator which can output envelopes, not just gate or trigger pulses. Dialectic Ping Pong is a quad bouncing ball envelope generator, based on a hidden mode of the Mutable Instruments Peaks module. Viznutcracker, sweet! is a quad "byte beat" equation generator, which can be used as an audio source to generate curious but often interesting 8-bit noises and tunes, or which can be clocked by an external source to produce "byte beat" control voltage sequences. "Byte beats" were first described in 2011 by viznut (aka Ville-Matias Heikkilä). References is a simple utility app that outputs specific reference voltages on each channel to help tune or calibrate VCOs and other modules.
