### Enable Timecode

Selecting this option will allow Atlas to be triggered via incoming Midi Timecode.&#x20;

Atlas supports these timecode standards.&#x20;

### Allow Timecode to move playhead

Selecting this option will allow incoming timecode to progress the playhead within the cue list.&#x20;

{% hint style="info" %}
This option can be useful for shows using both operator and musically fired cues. The operator can progress the playhead locally for cues outside of timecode.&#x20;
{% endhint %}

### Timecode Frame Rate

Select the desired timecode frame rate from the dropdown menu. Common formats are listed in the initial menu; a full list is available on the sub menu.&#x20;

{% hint style="danger" %}
If opening an existing show file or switching between timecode formats Atlas may display the error: "Malformed Timecode". This error informs the user that the programmed format needs attention in order to preserve the show.&#x20;
{% endhint %}

### Clamp all cues to a valid Timecode

Selecting this button will clamp all invalid timecode cues to the nearest value for the selected frame rate.&#x20;
