# Adding An Effect

## Adding an Effect

![](/files/-LaW6sUUhmranDBjukBP)

Click on the effect from the effects toolbar and drag the effect to the grid and release it between two timing marks on the row of the model you wish the effect to play on. You can then select and drag each end to stretch the duration of the effect or reduce the duration of the effect. The effect that you are working with is reflected in the (associated and open) windows to the left of the grid.

If no timing track is selected then you can drag and drop even if you have no timing marks but the effect defaults to 1 second long.

{% hint style="success" %}
Select and open the Views, Window menu and select windows to be opened.
{% endhint %}

### Radial Effect Wheel

Double-clicking an empty area of the sequencer grid pops up a radial wheel of effects centred on the cursor. Move the mouse out to the effect you want and click to drop it at that location, giving quick access to your key-bound effects without going to the effects toolbar. The wheel is not shown when you double-click on a timing track.
