Effects Demoscene

All effects · Using controls · Palettes

Generated from the running app by node tools/build-wiki-reference.mjs. Values are base defaults, before presets or audio modulation. Select values are zero-based indices in saved data; the UI shows labels. Ranges use the app’s stored units; controls marked as percentages may display a scaled value.
