#### OSC Transmit Indicator

This indicator will flash green when Atlas is transmitting OSC to the Spatial Engines. &#x20;

{% hint style="danger" %}
Atlas requires a [license](/installation-licensing-and-requirements/licensing.md) to output OSC
{% endhint %}

#### Device Status

The status of Spatial Audio Devices is displayed within the bottom toolbar. &#x20;

{% hint style="warning" %}
Devices will only display within the toolbar if they are enabled within [devices.](/show-settings/network/spatial-devices.md)
{% endhint %}

#### Yellow Boundary

When Atlas is connected and online with a spatial audio device the yellow boundary around a devices' status indicator determines which device Atlas is communicating with to display its "live overview" in online mode. Each device present can be selected to confirm communication from the device.&#x20;

#### Disconnected

When working offline the status of these will display as "Disconnected" and display the background colour of the device as red.&#x20;

#### Connected

When a valid spatial audio devices is present the relevant window will display "Connected" and display the background colour of the device as green. Currently a maximum of 3 devices is supported.&#x20;

#### Disabled

When OSC output is disabled for a spatial audio device a banner "disabled" is displayed across the device. No OSC output will be present. This function can also be controlled via OSC [(OSC Library)](/glossary/atlas-controls.md)

{% hint style="danger" %}
Atlas will not output OSC if it is not connected to at least one device.&#x20;
