You must unlock the Just Control Configuration window and stop the channel(s) to be able to make any changes.
A Channel can either be used by just:play or just:live user interfaces.
Stop the desired Channel by deactivating the checkbox in front of it. Stopping a Channel will also stop the Just Out engine and therefore the final output.
Select the Channel in the Devices & Channels list.
Click on the Format tab.
Select the desired scheduling user interface in the Scheduling drop-down menu.
Activate the checkbox in front of the Channel to start it again and to take over the changes you made.
Close the configuration window and drag the Channel from the Connections tab to the Multi-viewer area.
