Snare Roll Build

How it's made

Source

a drummer's stick bouncing on a snare head. Each stroke is a 1 ms stick tick, a 180–230 Hz head thump with a fast downward pitch glide, and a noise burst from the snare wires rattling against the head.

Body

the shell resonance adds a damped band around 200 Hz; the wires are band-passed 2–8 kHz and ring for 60–120 ms, so at high stroke rates the tails overlap into a continuous buzz.

Envelope

stroke interval shrinks exponentially from about 0.2 s to 0.025 s (accelerando); level climbs from about 25 % to 100 % (crescendo) while the wire band-pass cutoff rises, so the roll brightens as it builds.

Drop

after the last stroke a short silence precedes a final accent: a low sine falling 110 -> 40 Hz with a noise crack and a dark tail, the release of the tension.

Variation

`rng` jitters stroke timing (±7 % of the interval), level and wire tuning; presets change the length, acceleration, brightness and drop weight.
