DU-INO r-EUCLID and Celestial Modulator
Firmware for DU-INO (Detroit Underground)
Two Arduino sketches for the DU-INO, a dual Euclidean rhythm and random stepped-CV generator and a four-body gravity simulation that outputs four LFOs and orbit triggers.

Description
r-EUCLID produces two Euclidean trigger patterns with an external clock and reset input, and a random stepped CV from 0 to 5 V on each channel. Celestial Modulator simulates four bodies orbiting under gravity; each body drives an LFO output and the first two also fire a trigger every orbit. Its speed, gravity and entropy are set on the display, and gate inputs or the panel buttons reset the simulation or inject chaos. Each sketch lists the rear switch settings it needs.
Install notes
Install the DU-INO library in the Arduino IDE, open the sketch, choose the Arduino Uno board and upload over USB with the module's programming switch set to program. Then set the rear DIP switches to the layout given in the README and the sketch header and put the programming switch back to run.
