Make your own 16-step MIDI sequencer for real-time synthesizer jams! This CircuitPython-powered project uses a QT Py RP2040, four Adafruit seesaw-based Quad Rotary Encoder breakouts for note input/mutes, and a set of NeoPixel sticks for display indicators.
Double-click the first encoder knob to enter settings mode where you can:
- adjust the tempo
- pick octaves
- transpose keys
- select scale modes
- dial in velocity
- randomize notes and mute states
