How it's made
- Source
- a fingertip driving a wide plastic Enter keycap down onto its switch and then into the plate. Two contacts: the cap-on-slider strike (1–2 ms broadband tick) and, 20–55 ms later, the bottom-out against the case, a harder and slightly lower impact.
- Body
- the keycap rings in damped plastic modes (about 2–3.5 kHz, ratio ≈ 1 : 1.9 : 3.1, 12–45 ms); the case adds a hollow "thock" (170–330 Hz, 40–70 ms); the long stabilizer wire adds a faint metallic rattle at 4.5–7.5 kHz right after bottom-out.
- Envelope
- contact attacks under 0.5 ms; the first strike is the shorter and brighter, the bottom-out carries the weight; everything is gone by about 0.17 s, so the key sounds emphatic but not ringing.
- Variation
- `rng` mistunes the modes by up to ±3 % and varies the gap and level by a few percent, so repeated presses are not identical. Presets move pitch, damping, gap and thock weight (office, heavy, snappy, laptop).
