While in Patch view, selecting the project node or an individual space from within the Browser or Folders panel displays the "Control Channels" display, including information for all of the channels in the selection. All channels are listed in order based on the channel identification number.
When a specific primary space or the sub-space is selected, the title on the top of the page changes to reflect the new selection and the data is filtered to include only the channels in the scope of the selected space.
From this Control Channels display you can edit the arbitration for each channel by clicking inside the "Arbitration" cell and selecting a new setting.
When a specific processor is selected from the Browser, the display changes to the Processor Summary Display. Selecting either the "DMX" or "sACN Universe" changes the display from the Browser display to the Patch by Output Universe display.
When patch by space is the selection, you can add or remove DMX output relationships for the patched channels using the [Add Output] and [Remove Output] 
tools in the toolbar. Clicking [Add Output] displays an "Add Output Universe" dialog.
Select the universe from the available DMX output universe's in the drop down menu then click [OK].
