How it's made

Source

a slow-breathing pad made of air and tone. Air is decorrelated left/right pink noise; the tone is a stack of detuned triangle and sine voices on an open fifth-plus-ninth chord (root, 1.5, 2, 2.25 x root).

Body

the air passes a wide band-pass (Q ≈ 0.7) whose centre wanders between ~350 Hz and ~2.5 kHz on a random drift (period ≈ 8–20 s); the pad voices sit behind a low-pass at 600–3000 Hz that follows the same kind of slow drift, so the spectrum opens and closes without ever sweeping fast.

Envelope

nothing is struck. Each pad voice swells and fades on its own 6–14 s sine LFO (depth set by movement), so chord colour shifts gradually; the overall bed breathes by a few dB over ~10 s.

Layers

pad (warm body), air (noise bed), shimmer (very quiet high-passed noise above 5 kHz, drifting).

Variation

`rng` picks the detune of every voice (±5–12 cents), LFO rates/phases and drift paths; presets change root pitch, brightness, pad/air balance and movement depth.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
