Best practice for managing multiple instances with shared setlists

Frank,

I am having a similar issue on Mac and my post is : Syncing Setlists in Multiple Instances of GP with OSC on Mac

I’m trying to get a 3 instance configuration… Daisy chain works fine now, but I just can’t figure out how to get broadcast to multiple instances to work. The 3rd complains that the port is already in use.
How would you configure both the broadcaster and the receivers?
