Sketchbook
Hand-drawn visuals on paper: pencil strokes, ink and charcoal that sketch the music as it plays.

Controls
| Control | Group | Type | Default | Animation | Audio |
|---|---|---|---|---|---|
| Primary colorPrimary color used by the engine palette | Style | color | #1c1917 | Yes | No |
| Secondary colorSecondary color used by the engine palette | Style | color | #57534e | Yes | No |
| BackgroundBackground used by the engine palette | Style | color | #f5f0e6 | Yes | No |
| OpacityVisualizer opacity | Transform | range | 1 | Yes | No |
| Frame marginBreathing room kept clear at the frame edges. Audio-driven geometry is soft-limited to fit inside it; geometry scale deliberately is not | Transform | range | 0.035 | Yes | No |
| SensitivityBounded overall audio response | Audio | range | 1 | Yes | No |
| Spectrum rangeFraction of the frequency range the visual spans. The top of the FFT is near-silent air on most material, so at 1 the right-hand edge of every spectrum visual barely moves | Audio | range | 0.86 | Yes | No |
| Primary audio sourcePrimary audio source | Audio | select | bass | No | No |
| Frequency focusWhich part of the spectrum drives this visual; while no explicit audio source is set, the motion envelope follows this selection | Audio | select | full | No | No |
| Burst intensityGlow and trail swell on sharp hits; 0 keeps bursts off | Audio | range | 0 | Yes | No |
| Ambient bedProminence of the standing background layer behind the beat-born elements | Effects | range | 1 | Yes | No |
| Wake lengthHow far motion trails stretch behind beat-born travelers; 0 removes the wake | Effects | range | 1 | Yes | No |
| Pulse coreProminence of the source element the beat emanations fire from; 0 hides it | Effects | range | 1 | Yes | No |
| Peak memoryHow long peak markers hold before fading; 0 disables the memory layer | Effects | range | 1 | Yes | No |
| Audio contributionMaximum contribution from the primary audio route | Audio | range | 0.55 | Yes | No |
| Audio dynamicsHow much of the band's movement reaches the visual. 1 = full dynamics; 0 holds it at a steady level for a calmer, more constant look | Audio | range | 1 | Yes | No |
| Audio attackEnvelope attack in milliseconds | Audio | range | 45 | Yes | No |
| Audio releaseEnvelope release in milliseconds | Audio | range | 240 | Yes | No |
| Geometry scaleGeometry scale | Geometry | range | 1 | Yes | Yes |
| ThicknessThickness | Geometry | range | 2 | Yes | Yes |
| SpeedTime-based motion; default major cycle is 6–12 seconds | Motion | range | 0.1 | Yes | Yes |
| Color modeDuo palette, primary→secondary gradient, or full rainbow sweep | Style | select | duo | No | No |
| GlowGlow | Effects | range | 0.55 | Yes | Yes |
| Global glowShared emissive strength across the frame | Effects | range | 0.35 | Yes | Yes |
| Pulse intensityBeat pulse scale for spawn, size, and shake | Effects | range | 1 | Yes | Yes |
| Beat responseHow hard every engine hits on each detected beat | Audio | range | 1.2 | Yes | Yes |
| Beat smoothingHow long each beat hit rings out before it settles | Audio | range | 0.35 | Yes | Yes |
| Beat attackSeconds for a hit to swell to full. 0 snaps instantly | Audio | range | 0 | Yes | Yes |
| Beat releaseSeconds for a hit to fade, overriding Beat smoothing. 0 follows it | Audio | range | 0 | Yes | Yes |
| Beat shakeFrame kick strength on each beat | Effects | range | 0.6 | Yes | Yes |
| Motion echoMotion echo | Effects | range | 0 | Yes | Yes |
| BlurBlur | Effects | range | 0 | Yes | Yes |
| Chromatic aberrationChromatic aberration | Effects | range | 0 | Yes | Yes |
| Beat sync allRoute beat energy into spawn, shake, pulse, speed, and scale | Audio | boolean | true | No | No |
| Hand wobbleHow far every stroke wanders from a ruler line, like a hand-held pencil | Sketch | range | 0.5 | Yes | Yes |
| Line boilHow often lines are redrawn with a fresh wobble, like hand-drawn animation; 0 holds them steady | Sketch | range | 0.5 | Yes | Yes |
| Paper grainStrength of the paper tooth that breaks up the strokes | Sketch | range | 0.6 | Yes | Yes |
| Stroke densityExtra pencil passes, tighter hatching and denser scribbles | Sketch | range | 0.5 | Yes | Yes |
