System: spectrum

Structural

Parameter	Default	Range	What it does
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.
mirror_order	1	1 – 12	Repeats the geometry this many times around the centre; 1 draws it once.

Modal

Parameter	Default	Range	What it does
base	0.06	0 – 1	Height the readout sits at when the band is silent.
scale	1.2	0 – 4	How far a full band pushes the readout above its base.
curve	1	0.05 – 4	Exponent on each band’s level: 1 is linear, below 1 lifts quiet detail, above 1 pushes it down.
radius	0.35	0 – 1	Radius of the ring the readout is drawn around, in the radial layouts.
span	1	0 – 1	How much of the frequency axis is shown; below 1 the top end is cut.
baseline	-0.85		Where the flat layout’s zero line sits vertically.
rotation	0	0 – 1	Turns the readout, as a fraction of a full turn.
thickness	6	0.5 – 12	Stroke width in pixels at the render target, before softness widens the falloff.
hue	0.55	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.
hue_spread	0	0 – 1	How far along the palette the colour travels from one end of the figure to the other.
saturation	1	0 – 1	Pulls the scene’s colour toward grey; 0 is fully desaturated, 1 is the palette’s own.
palette_mix	0	0 – 1	Crossfades from the preset’s palette to its second one; 0 is the first, 1 the second.
palette_contour	0	0 – 1	Draws a line at each band edge when the palette is stepped; 0 draws none.
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.
glow	1	0 – 4	Brightness of the halo around each stroke, on top of the stroke itself.
softness	0.25	0 – 1	How far a stroke’s edge fades out; 0 is a hard line, 1 a wide glow with no core.
stroke_blend	0	0 – 1	Moves the stroke from additive light toward opaque paint, so crossings stop brightening.
zoom	1	0.25 – 4	Scales the whole scene about its centre; above 1 fills more of the frame.
pan_x	0		Slides the whole scene sideways, in the scene’s own units rather than pixels.
pan_y	0		Slides the whole scene vertically, in the scene’s own units rather than pixels.
mirror_reflect	0	0 – 1	Alternates the repeats into mirror images rather than plain rotations.
