This is a module in Eurorack format. Basically it is complex wave 4-channel LFO, based on ESP8266 and MCP4728 Quad DAC. It has sync, it has patterns, perlin noise smooth random, all controlled with one potentiometer; each channel has different logic, but all complex lfos are based on Adventure Kid's Waveforms.
