Ableton Link is a system for synchronizing multiple music applications, which may be running on different devices, by providing unified, real-time tempo control. Link-enabled programs find each other automatically when they are on the same network. Any “player” in the network can change the tempo and the others follow. No configuration of any kind is necessary, only that it be enabled.
To enable Gig Performer to sync to Ableton Link, click on the Link button that is always in the upper toolbar.
