Since the release of ProPresenter 7.8, ProPresenter now has access to Network Link. This update is available for users who have an active ProPresenter+ plan as of December 2, 2021. ProPresenter Network Link can control multiple different computers that are a part of the same network group, which is created within ProPresenter. Using Network Link requires that you be on the same network connection, and that your computer's are able to communicate with each other across the network.
ProPresenter Network Link can control multiple different computers that are a part of the same network group, which is created within ProPresenter. The content can be controlled from any computer, so there is no 'master' computer as anyone can assume control from any computer within that group at any time.
Joining a Group
ProPresenter computers can be controlled by joining a network group created within ProPresenter. To join a Group, make sure that both computers have "Enable Link" checked in the Network tab of ProPresenter Preferences, and make sure that they are both on the same network. As shown in the image below, choose the "+" button to add a connection.
Enter in the IP and Port number found in the network tab of ProPresenter preferences on the other computer, and select continue.
Once this is done, you will be prompted to create a group if neither computer is already in a group. You should see the computer connected at the bottom and see some information about this connection. You can have multiple groups that exist on the same network.
When triggering content via indexes, it doesn't matter what the content is, as long as a cue exists on both computer at the same index. Triggering is all done off of Index. At the time of this writing, Library, Library Playlist, Slide content, Media Playlists, and Media Playlist Content is triggered entirely off of an Index. For Example, if you trigger the 4th slide of the 10th item in the 3rd playlist, it will trigger the 4th slide of the 10th item in the 3rd playlist on all connected computer within that group. The Media bin and Audio Bin content functions the exact same way.
Triggering and Adjusting Show Controls
You can also configure and trigger the timer type and values within Timers, the token values and message content within Messages (themes are not adjusted), and you can trigger Props, Macros and Stage Layout Changes. All of these are based off of an Index as well, so when adjusting one, it will adjust whatever the corresponding index of the item over there, per show control.
To configure items within a timer and a message, just make sure a timer or message is already created on any computer within the network group, and then any adjustments made on that timer or message value will also be adjusted on the other computers in the group. Props, Macros, and Stage Layouts are triggered via index just as everything else is.
