Overview
A classic Euclidean rhythm sequencer: distribute a number of hits as evenly as possible across 8 or 16 steps. The hit count, step length, and an output probability are all on the panel, with CV control over the number of hits and an external clock and reset.
Panel & I/O
| Control | Pin | Function |
|---|---|---|
| POT1 | A0 | Hits — number of hits |
| POT2 | A1 | Prob — output probability |
| POT3 | A2 | Steps — step length (8 ↔ 16) |
| BTN | D4 | Reset step |
| LED | D3 | Trigger output |
| F1 | D17 | In — Reset step |
| F2 | D9 | In — Clock |
| F3 | D10 | In — Number-of-hits CV |
| F4 | D11 | Out — Trigger |
Features
- Selectable 8- or 16-step patterns
- Adjustable hit count with CV control
- Per-step output probability for evolving, generative rhythms
