Default demo track · live audio-reactive settings

Lemmings is an expressive audio-reactive composition in the Creative category. Open it from the left visualizer list, start an audio source, and use the settings panel to shape its response.

Open Lemmings

Launch the visualizer with its matching left-nav entry selected.

Quick start

Start the demo track, choose a local audio file, or enable a live input.
Try a preset or style first, then open the section for the part of the image you want to change.
On a control with Assign modulation, open the source picker, choose a signal, and watch the slider's live fill.
Use Reset to Defaults whenever you want to return to the original look.

On a control with Assign modulation, select the activity icon to open Modulate with. Choose a named source, or choose — None to leave the control unmodulated. After you assign one, its name appears below the slider; select that name to edit the route, or use Clear modulation to remove it. The slider track shows the live signal reaching the control.

Modulated control	Section	What the route changes
Exposure	Material	Sets the overall rendered brightness.
Light Brightness	Material	Sets the visible strength of light brightness.
Ambient	Material	Controls the scene-wide fill light.
Specular	Material	Controls specular; higher values increase the effect and lower values reduce it.
Shadow Brightness	Material	Sets the visible strength of shadow brightness.
Ray Weight	Material	Controls ray weight; higher values increase the effect and lower values reduce it.
Ray Exposure	Material	Sets the overall rendered brightness.
Floor Scroll	Material	Controls floor scroll; higher values increase the effect and lower values reduce it.
Turntable	Material	Controls turntable; higher values increase the effect and lower values reduce it.
Fog Density	Material	Makes the scene fog thinner or denser.
Time Speed	Animation	Sets how quickly time changes or moves.
Walk Reactivity	Animation	Controls walk reactivity; higher values increase the effect and lower values reduce it.

Tips for a better audio visualization

Assign different bands to structure, motion, and light instead of routing every control to Volume.
Try assigning Bass to Exposure, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
