2026
six-headed multi-pitch density

scylla is a six-headed multi-pitch density effect. 24 voices (6 pitch layers x 4 voices each) gated by randomized density control. chord spread is hardcoded to: 0, -12, +12, -24, -36, -12 semitones.

toggle modes

hunger

controls voice count and gate aggressiveness:

  • patient: 1 voice per layer (6 total), sparse texture
  • default: 4 voices per layer (24 total), balanced
  • ravenous: 4 voices per layer, boosted gate threshold, dense and aggressive

hunting style

controls gate noise correlation across voices:

  • coordinated: all voices in a layer open/close in unison, rhythmic
  • default: each voice has independent random gating
  • pack: voices paired (0&1, 2&3 share gate noise), clustered activity

catch & release

controls gate envelope shape:

  • default: smooth gating with standard lag
  • devour: slow release (0.25x decay rate), voices linger before closing
  • snap: instant attack, fast release, percussive gating

footswitch

dive (footswitch 1, momentary): sweeps interval down toward -24 semitones while held at ~48 semitones/second. ramps back to knob position on release.
