I have now published the code for my Sonic Pi Orchestra setup which utilises OSC messages sent to the network broadcast address with the aid of a python script to synchronise the computers together. a github repository contains the code, and I have added a 52 minute video which details and demonstrates the code in action.
Spent today developing a TouchOSC interface that streamlines setting up the latency settings for the individual computers. Now all the values are input via TouchOSC. Much quicker and easier. Will add code to repository soon.
