Yes, Dante is the way to go. It does work on current GLD firmware (saw it on a demo this week)
You install the virtual soundcard application on your PC/Mac and then it’s just a case of a single network cable between your GLD and your computer.
You then need some software on your computer to record it, such as Reaper. I think anything that is ASIO (PC) or CoreAudio (Mac) compatible should work?
Reaper also has advantages for the volunteer environment such as being able to set up templates, macros etc to do what you need, although it’s a bit of a trick to set it all up in the first place.
