How it's made
- Source
- a fingertip lifting off a small plastic button. The return is gentler than the press: the spring pushes the cap up against its stop with a soft 1.5–4 ms low-passed noise contact, then a tiny latch tick follows about 3–6 ms later as the stem seats.
- Body
- the key cap rings in two lightly damped modes (about 2.4–4.2 kHz, ratio ≈ 2.2), a little higher than the press because less mass is loaded on it; the housing adds a small, short "tup" at 300–600 Hz with far less weight than the press thock.
- Envelope
- attack under 0.5 ms; the cap modes fade 60 dB in 15–50 ms, the housing tup in about 15 ms; the whole event is over in roughly 0.1 s and nothing sustains.
- Variation
- `rng` mistunes the modes by ±3 % and shifts the latch delay slightly, so repeated releases differ. Brightness opens the contact filter, body scales the housing tup, latch scales the seating tick; presets trade these for soft, crisp, mechanical and muted switches.
