Gig Performer now allows for better rackspace and song changes between multiple instances of Gig Performer. Requirements are that rackspaces and songs have the same names across instances. Beside the usual OSC setup, the synchronization setup is quite straightforward. One Gig Performer instance is set to Send rackspace or song changes and one (or more) other instances are set to Respond to incoming rackspace or song changes.
In the example screenshot below are shown OSC options of the main Gig Performer instance and the "OSCtest" instance:
Provided that rackspace names are the same, clicking on the desired rackspace in the main instance will automatically change to the corresponding rackspace in the "OSCtest" instance.
