How it's made

Source
a small tuned mallet percussion bar (marimba/vibraphone-like) struck repeatedly. Each strike is a 1–3 ms high-passed noise tick on top of a sine-partial voice.
Body
each hit rings a fundamental plus stretched partials (2.0×, 3.99×, 6.3×); upper partials die 2–6× faster than the fundamental, so every hit is bright at the attack and pure in the tail.
Envelope
hits get closer by a constant ratio (gap × 0.7–0.9 each step), like a player speeding up; early hits ring 80–150 ms, the last hit rings ~0.5 s so the streak resolves instead of cutting off.
Pitch
each hit steps up one degree of a scale (pentatonic, major, whole-tone or chromatic) from the base note; the strikes also grow louder and brighter toward the end.
Finish
the final hit adds an octave-up shimmer partial and a high-passed air sparkle (5 kHz and up).
Variation
`rng` detunes every partial by ±0.2 % and shifts the strike timing by ≤ 4 ms.
