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.

Tips for a better audio visualization

Use lower modulation amounts than you would for a foreground effect so the background supports the mix instead of competing with it.
Try assigning Bass to Path Scale, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
