Free State FX - FSFX 108: Ornament & Crime
Ornament & Crime is basically a little computer with a fixed set of user controls, and signal inputs/outputs. What the encoders do, and how the inputs are used is specific to each application (app). Each app serves a unique utility function i.e. voltage quantizer, standard voltages, sequencer, envelope generators, etc. An OLED screen is used for navigation, as well as monitoring outputs.
Ornament & Crime has been one of the most popular eurorack modules for several years, and is now available in the 5u format from Free State FX.
