Source: a soft, breathy whistle-like sine that slides upward and settles on a held note, like a small glass tone being gently bowed; no struck transient, so nothing is percussive.
Body: a fundamental sweeping from `pitch / span` to `pitch` along an eased curve, a quiet octave partial (about 12-35 % of the fundamental) following the same glide, and a second sine detuned by about 4 cents that adds slow beating warmth. A band-limited breath of pink noise rides the glide for air.
Envelope: a 25-60 ms fade-in (no click), the glide takes 0.12-0.3 s, the note then rings out exponentially for 0.12-0.3 s, and a final fade to zero closes the output.
Variation: `rng` shifts the detune of the second sine by a fraction of a cent; macros set the landing pitch, glide span and time, softness of the attack and brightness. Presets change register, glide shape and tail.
