How it's made
Source
a charge-up of magical energy released into a chord. Three layers: a pad of detuned band-limited saws and triangles on the chord tones, a band-passed air shimmer, and sparse glassy sine sparkles.
Body
the pad sits on a root, third/fifth and octave (ratios from the chosen chord); a low-pass opens from ~500 Hz to ~5 kHz during the swell, so the spectrum climbs. At the bloom each chord tone is struck as a bell-like voice: fundamental plus stretched partials (2.01x, 3.02x, 4.17x) with faster-decaying uppers.
Envelope
the swell rises over 0.5-1.3 s (curved, slow start), the pad and air then release in ~0.2 s as the bloom strikes (2 ms attack, 25 ms stagger per note); the bell ring decays 60 dB over 0.5-1.8 s. Sparkles cluster toward the end of the swell, accelerating like energy building up.
Finish
an octave-up ringing pair detuned by 0.35 % beats slowly under the chord tail, giving a shimmering ring-out instead of a flat decay.
Variation
`rng` detunes every oscillator by a few cents, times the sparkles and picks their chord tone; `pitch`, `chord`, `swell`, `ring` and `shimmer` reshape the cast; presets move root, chord and brightness.
