I have been running 2 FSProjects for several years not. All the Mix Pres Match, and this was before zero latency existed in Studio One. The Digimax FS has no way of connecting to the FSProject digitally for wordclock syncing. The Digimax FS has ADAT and BNC to allow it to expand hardware that allows it to connect to them with the ADAT and or BNC. So, daisy chaining 2 or even 3 FSProjects together is going to be your best bet.
