Pi Pico Random Looping Sequencer

Raspberry Pi Pico sequencer with quantised random CV and probability driven mutation · DIY Synth Manila

One to 16 steps with over 40 scales, an OLED menu and rotary encoder. On each clock a probability decides whether a step gets a fresh random value, so the loop slowly mutates. Output goes through an MCP4725 DAC. The archived Random-Looping-Sequencer repo holds the older firmware only.
