Modularino - arduino based modular step-sequencer

thingiverse

This Arduino-based step sequencer is designed specifically for modular synthesizers and is currently a work in progress. It features two independent sequencers that can be controlled separately, each with two rows of potentiometers and three outputs. The rows' individual outputs make them function as 8-step sequencers, but the third output alternates between the first and second row voltages every 8 steps, creating a 16-step sequence. The planned updates include connecting the brain switch to the Arduino for two operating modes: one as described above and another for controlling patterns, addressing individual steps, and synchronizing with a DAW via USB. Currently, the Arduino is only needed for routing, as it can be replaced by a clocking circuit. The enclosure can be customized to fit any self-built case, using a laser-cut front plate and an external enclosure like the one from Conrad (http://www.conrad.de/ce/de/product/520780/PULTGEHAeUSE-HIT-PULT/0203053). The parts list includes an Arduino, 2 AD420AR modules, 2 74HC4067 switches, 4 74HC595 shift registers, 32 10k linear potentiometers, pot knobs, 34 LEDs and sockets, a flip switch, and ten 3.5mm audio jack sockets.
