Lets look at this from something we all know, graphics applications..
Airboss is like MS Paint, Saturn is like Adobe Photo Shop.
Satrun is much more effcent when it comes to timing and event scheduling. Airboss is good at timing and scheduling, but all it does is switch sources and doesnt play the clips its self. Saturn actually plays the files its self using a file server.
I think Saturn is back up now, scheduled events seem to be running on cue.
What are the technical differences between Airboss and Saturn?
