How it's made

Source
a mono synth bass voice struck once. A sine sub-oscillator carries the fundamental (30–90 Hz); three slightly detuned band-limited saws (two at the fundamental, one an octave up) supply the harmonics.
Body
the saws pass through a tanh saturator (the grit) and then a low-pass whose cutoff starts open (0.4–3 kHz) and closes within ~0.25 s, so the attack is gritty and the tail collapses into a clean sub. The sub drops in pitch over the first ~40 ms, which gives the stab its punch.
Envelope
a 4 ms attack avoids a click, then an exponential decay (0.12–0.6 s) shapes the stab; a short release after the ring finishes the hit at about 1 s.
Variation
`rng` detunes the saws by a few cents and sets their start phase; grit, tone, decay and drop control the saturation drive, filter start, body length and pitch-drop depth. Presets move pitch, grit and decay.
