How it's made
Source
an analog-style string/synth pad. Each chord note is a stack of three band-limited saws detuned by about ±7 cents, so the partials beat slowly against each other (chorus-like shimmer, 0.3–1 Hz).
Body
a 2-pole low-pass at 600–1800 Hz removes the buzzy upper partials; a sine one octave below the root adds warmth; a soft high shelf cut keeps everything above 6 kHz quiet. The chord is an open Am add9 (A2 E3 A3 C4 E4 B4), a calm, unresolved colour.
Envelope
no transients. Every note swells with its own slow amplitude wave (periods of 12, 6 and 4 s so the loop holds whole cycles), staggered in phase, so the chord breathes and the notes arrive one after another.
Modulation
a 12 s sine LFO opens and closes the filter by about ±25 %; a slow random drift moves each voice pitch by a few cents; notes alternate between left and right and the whole bed is widened.
Variation
`rng` picks the detune of each saw and the LFO phase; `brightness` sets filter cutoff, `movement` the depth of filter and swell modulation, `detune` the spread of the saw stack; presets change the chord voicing register, brightness and motion.
