RATCHET
Clock ratchet generator with random hits
4 HPEurorack
RATCHET turns a plain clock into a living rhythm. Every clock pulse passes straight to the output, and every few steps – or at random – it becomes a fast burst of 1 to 8 hits, like a snare roll or a hi-hat flurry. Bursts are spread evenly inside the clock step and always end before the next beat, so your groove never drifts or loses a step.
Features
- Ratchet every 4, 8, 16, 32, 64 or 128 clock steps (RATE knob)
- 1–8 hits per ratchet, evenly dividing the step – 3 hits give a triplet (HITS knob)
- RANDOM HITS – random number of hits (1 up to the HITS setting) on every ratchet, always on the grid
- RANDOM RATE – each step gets a chance of a ratchet (0–25 %, set by the RATE knob)
- Both random modes can be combined; LEDs show active modes and blink when a mode acts
- CV inputs for HITS and RATE (0–5 V) – plugging a cable takes over the knob
- Automatic tempo detection from the incoming clock
- Button settings are remembered after power-off
- Activity LEDs on TRIG IN and TRIG OUT
