How it's made
Source
stiff parchment slides against a wooden table while stored curl releases in uneven steps. Pink friction noise supports short, band-limited white-noise flexures rather than pitched oscillators.
Body
broad parchment flex bands at 650-1800 Hz and dry fibre noise at 2-7 kHz; Q stays below 1.5. A quiet 180-650 Hz contact layer gives table weight without a ringing wooden impact.
Envelope
a 30 ms opening grip, two overlapping slide surges, then a slowing curl and 180 ms settle. Default movement ends at 1.95 s; every grain has a 1.5-6 ms attack and 12-85 ms release.
Events
28 irregular flexures cluster as the curl advances; finer 55-110/s fibre grains follow pressure. Brightness falls as motion stops; no room reverb or full-band impulses are included.
Variation
seeded timing, grain spectrum, strength and narrow pan vary independently. Length controls hand speed; stiffness controls flex weight; dryness controls fibre grain; contact controls table drag.
Presets
brittle archive, thick hide, careful opening and brisk desk reveal vary material and gesture.
