From the project

A 1U Eurorack Module for Triggering CV Sequences

This is a 1U Eurorack module that maps four trigger inputs to four CV outputs. Inspired by the CV capabilities of Pamela's New Workout, cv-binary-sequencer aims to produce customizable and intricate CV outputs for controlling other modules. There is a mapping of the 16 possible trigger inputs to a combination of CV outputs. On each trigger edge of an input CVs will change to the value specified by the mapping.
