Ornament and Crime (Black)

uO_C module from Big T Music with black and gold panel

The uO_C is a polymorphic control voltage generator or in other words, a swiss army knife of the Eurorack ecosystem and quite possibly the best bang for your buck module available. It consists of a multitude of apps that are largely intuitive on the surface yet offer a great deal of depth easily accessible as and when required with limited menu diving.

Take the quad quantiser app ‘Quantermain’ for example. Not only is it capable of quantising four different external CV sources independently, it also has internal CV sources, per channel, that you can utilise including, but not limited to, a model of the highly popular Turing Machine as devised by Tom Whitwell. There is also a dual sequencer app ‘Sequins’ which provides two sets of pitch CV and trigger outputs, a quadrature LFO app ‘Quadtraturia’ and a quad envelope generator ‘Piqued’ to mention but a few of the applications.

In addition, there is also an alternative firmware available named Hemisphere Suite which splits the module down the middle offering two distinct hemispheres (left and right) that run an app each. The app selection is entirely different to the stock firmware and has a more utilitarian flavour but nonetheless just as inspiring to work with. Outlined below are the apps available on the stock firmware. For more information on the apps available within Hemisphere Suite, please visit https://github.com/Chysn/O_C-HemisphereSuite/wiki

The apps currently available in the Ornaments and Crime Firmware 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.
• Meta-Q is a dual-channel quantiser, similar to Quantermain, but also offering scale and note mask sequencing.
• 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.
• Sequins is a dual-channel step sequencer offering 4 “tracks” of up to 16 steps each; tracks can themselves be sequenced.
• 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).
• Acid Curds is both a chord quantiser (sometimes called a “harmonic quantiser” for external pitch voltages), and a chord progression sequencer.
• References is an utility app that outputs specific reference voltages on each channel to help tune or calibrate VCOs and other modules. It also includes a high-precision frequency meter and note tuner, a high-precision BPM (beats per minute) tempo meter, and a closed-loop calibration mode.
