Audio modulation
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 | Lighting | Sets the overall rendered brightness. |
| Light Brightness | Lighting | Sets the visible strength of light brightness. |
| Ambient | Lighting | Controls the scene-wide fill light. |
| Specular | Lighting | Sets how shiny the characters look; higher values add brighter, sharper highlights where the light catches them. |
| Shadow Brightness | Shadow Light | Sets the visible strength of shadow brightness. |
| Ray Weight | God Rays | Sets how bright each light shaft is; higher values make the God Rays bolder and more solid. Available when God Rays is on. |
| Ray Exposure | God Rays | Sets the overall rendered brightness. |
| Floor Scroll | Floor | Sets how fast the checkered floor scrolls beneath the characters; 0 holds it still and music can speed it up. |
| Turntable | Floor | Sets how fast the whole crowd slowly spins around like a turntable; 0 stops the rotation. |
| Fog Density | Atmosphere | Makes the scene fog thinner or denser. |
| Time Speed | Animation | Sets how quickly time changes or moves. |
| Walk Reactivity | Animation | Scales how strongly the music drives the characters to walk; they walk when the result passes Walk Threshold and stand still otherwise. |

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.
