# Starting or stopping an MPTS
<a name="starting-an-mpts-output"></a>

On the Conductor Live main menu, choose **MPTS**. 

To start an MPTS, select the **Start** icon. Note that starting an MPTS doesn't automatically start the programs (channels) on the Elemental Live nodes.

To stop an MPTS, select the **Stop** icon at the right side of the MPTS. Note that the sources in the MPTS (the channels, passthrough programs, and passthrough streams) do not stop.
