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.

Tips for a better audio visualization
- Use bass for large fills or zoom and highs for small pixel detail; this reads clearly even on a distant screen.
- Try assigning Bass to Scroll Speed, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
