Open Cell Block 4
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.
| Modulated control | Section | What the route changes |
|---|---|---|
| Generations | Colony | Controls generations; higher values increase the effect and lower values reduce it. |
| Hue | Colors | Moves the color around the color spectrum. |

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 Generations, then compare Mid, High, and Volume while the demo track plays. The slider's live fill shows the signal reaching that control.
