How it's made
Source
a full orchestra hitting one short chord together. Brass is a lip-reed buzz (harmonic-rich saw-like wave) and strings are bowed sawtooth waves from many players, each slightly out of tune with the others.
Body
brass bells brighten with loudness, so a low-pass sweeps from ~600 Hz up to 2–6 kHz within 25 ms and falls back to ~1 kHz; strings sit behind it at 3 detuned voices per note (±7 cents), low-passed near 3 kHz. A hall-free, dry rosin/breath noise burst (band-passed 2–5 kHz) marks the bow and lip attack.
Envelope
brass attacks in ~8 ms, strings in ~14 ms; both decay exponentially (0.2–0.7 s) with the strings ringing a little longer, then a short fade-out ends the one-shot at about 1 s.
Chord
stacked semitone intervals from the root (major, minor, minor 7th, power fifth), with the root doubled an octave down in the low brass and the top note an octave up in the strings.
Variation
`rng` detunes every voice by a few cents and jitters each player's onset by up to 3 ms, so the section sounds like people rather than a chord synth; presets change chord quality, brightness and decay.
