Overview
A PCM break-beat player. Slice points are baked into the firmware and chosen via CV, so a trigger fires playback from the selected start point. Speed and length are continuously variable in real time, loop mode auto-retriggers at the end, and a long button press swaps between two stored drum breaks.
Panel & I/O
| Control | Pin | Function |
|---|---|---|
| POT1 | A0 | Speed — playback rate (0.7–1.5×) |
| POT2 | A1 | Length — playback length (0.3–2.3 s) |
| POT3 / CV | A2 | Start — one of six slice points |
| IN1 | GPIO7 | In — Trigger (rising edge) |
| IN2 | GPIO0 | Out — End-of-playback 5 ms pulse |
| BUTTON | GPIO6 | Short = play · medium = loop toggle · long = swap sample |
| OUT | GPIO1 | Out — 10-bit PWM audio (~36.6 kHz) |
| LED | GPIO5 | Loop-mode indicator |
Features
- Six pre-programmed slice points, CV-selectable
- Real-time speed (0.7–1.5×) and length (0.3–2.3 s) control
- Auto-retriggering loop mode
- Two stored breaks, swappable with a long press
- End-of-playback pulse for chaining
