Mashup

Route up to eight sources through one grayscale control — posterize the control’s luminance into bands and show a different surface in each band.

mixer/mashup reads the luminance of its source input and divides the 0…1 range into layers equal bands. Each band displays a different engine surface: the darkest band shows the first layer, the brightest shows the last. smoothness feathers each band boundary so adjacent sources cross-fade instead of meeting at a hard edge.

It is the luminance-driven cousin of synth/remap: where Remap routes surfaces to polygon zones, Mashup routes them to gray-level bands. Like Remap, every input — including the control — is an explicit slot wired in DSL with read(oN).

Notes

• The control input is only sampled for its luminance — its color never shows directly unless a band’s layer source is unwired, in which case that band falls back to showing the control input.

• Bands are assigned darkest → brightest, so re-ordering the wired sources re-orders which luminance range each occupies.
