How it's made
Source
a warm synth-like pad (bowed strings / choir-ish) swelling under a few struck glass-bell chimes. The pad is a stack of slightly detuned triangle and saw oscillators on a major triad plus a sub-octave root.
Body
the saws are low-passed (about 700-3500 Hz) with a filter that opens as the swell grows, so the spectrum brightens then relaxes; detune of 3-9 cents between left and right copies gives a slow chorus beat and a wide image. Chimes are sine partials at 1 : 2.76 : 5.4 (bar-like stretch), upper ones decaying faster.
Envelope
pad attack 0.3-0.9 s on a smooth curve, short hold, then a release to silence at ~1.8 s; chimes strike in 3 ms, ring 0.5-1.1 s and arpeggiate upward through the chord one or two octaves above.
Variation
`rng` tunes each oscillator by a few cents and jitters the chime timing and pan; macros set the swell time, warmth, chime level and chord colour (major, add9, major 7th, sixth).
