Animation & ControlModifiers
Sound
Reads one of six fixed frequency bands from the audio input.
The Sound node is the quickest way to make a parameter audio reactive.

- Band, Gain, Decay
- Found in the node graph under Modifiers → Audio
The image on the right is the example patch itself. Drag and drop it onto the app, or load it with File → Load, to open the full graph. The modifier drives the Scale of a Hexagonal generator; it moves when audio input is running.
Inputs and outputs

| Port | Type | Purpose |
|---|---|---|
| Modifier | Modifier | Drag it onto a parameter row, or wire it into another modifier's input. |
Parameters
- Band — Bass (default), Low Mid, Mid, High Mid, High, Full.
- Gain (0.1–8, default 1.5).
- Decay (0–0.99, default 0.85) — how slowly the level falls.
Every slider has a per-parameter animation bar and can itself be driven by another modifier.
Examples
Bass pump — the defaults bound to a generator Scale.
Troubleshooting
Nothing moves — audio input is not running. See Audio Reactive.
