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.

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

Let bass control particle scale or spread, while highs drive sparkle or trail detail for a clearer sense of depth.
Try assigning Bass to Major Radius, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
