# OSC

{% hint style="success" %}
You can find a full list of Atlas's OSC library in the [OSC Glossary.](https://help.atlas-control.app/glossary/atlas-controls/osc-library)
{% endhint %}

{% hint style="info" %}
Atlas is fixed to listening to incoming OSC on port 5050.
{% endhint %}

#### Assigning a Debounce Time

Atlas has the ability to ignore OSC commands that occur within a given timeframe. By entering a time in this window Atlas will not respond to the same command within that time.  By default this setting is 0.20 seconds. 

#### Allow OSC to move playhead

Selecting this option will allow external OSC commands to move the playhead within the workspace. 

#### Custom OSC Trigger

Atlas can be triggered via a custom OSC Trigger message. To assign a custom string to trigger Atlas's cuestack enter the necessary string within this window. 

{% hint style="info" %}
An example where the custom OSC Trigger can be used includes the triggering of Atlas scene for scene alongside a sound console.  By creating matching scene numbers in Atlas to coincide with the console Atlas will seamlessly mirror the console scene structure. 
{% endhint %}

### Atlas Trigger Output

Atlas can output a specific OSC command when it is triggered. You can sepecify the IP address and port here.
