Source: two soft felt-mallet taps on a warm wooden tone bar, played as a falling minor interval (default a minor third), the second note a little quieter than the first.
Body: each note is a strong fundamental plus a weak, quickly fading 2nd partial and a very faint 3rd partial (2.0×, 3.01×); a gentle low-pass keeps the timbre dull and round.
Excitation: a few milliseconds of low-passed noise (the felt thump) at the strike, whose cutoff follows the pitch and the brightness control.
Envelope: a 4 ms rounded attack, then an exponential decay of 0.12–0.7 s; the notes overlap slightly and the whole phrase is closed by a short fade.
Variation: root pitch, interval size, note spacing, ring time and brightness; `rng` detunes each partial by a fraction of a percent so the tone is not perfectly synthetic.
