4HP Arduino Nano Eurorack module for custom CV and gate sketches
MOD1 is an open-source 4HP Eurorack module by the maker HAGIWO, built around an Arduino Nano-compatible board. It has four 0 to 5 V jacks that can be set up as inputs or outputs, three potentiometers, a button and an LED, and runs from +12 V only. Its function is set by the Arduino sketch uploaded to it, so the same hardware can act as an LFO, sequencer, quantizer or other CV and gate tool.
Firmware is written as Arduino sketches and uploaded over USB with the Arduino IDE or a browser-based uploader, so any sketch can replace what is on the board. The maker's build page does not state a licence for the hardware or the example code.
Collection of Arduino sketches for the HAGIWO MOD1, including a three-channel LFO, a Grids-style drum pattern generator, a quantizer, a Euclidean sequencer, a Turing-machine with sample and hold, an attenuverter and a percussion envelope.
