How it's made
Source
a monophonic analog-style synth lead playing a four-note phrase that steps down a natural minor scale (5th, 4th, 3rd, then the root). Each note is a stack of three slightly detuned band-limited oscillators (saw, pulse or triangle) plus a soft sine one octave below for weight.
Body
a resonant low-pass (Q ≈ 1.1) closes over each note, from about 1.7x to 0.5x its cutoff, so every note starts bright and darkens like a filter decay; lower notes are darker because the cutoff follows pitch.
Envelope
12 ms attack, a gentle level droop while the note holds, and a 0.1–0.9 s release that overlaps the next note. The phrase slows down: note lengths 0.4, 0.4, 0.5 s, then a 1.5 s final root with a long release. Vibrato (5 Hz) fades in only after ~0.25 s of the final note; its pitch also sags a few cents.
Variation
`rng` randomises oscillator start phases and detune by a few cents per note. Macros set the root pitch, tempo, brightness, vibrato, detune and the sag; the presets change waveform, register and mood.
