Reply to Using Two s2's at once?

Hey, long time lurker and new poster here. So my buddy just recently got his own s2, and I was wondering if there was any way that we could use both of ours at the same time on the same laptop, maybe to play decks C and D, or maybe one to control sample decks with better accuracy? Or maybe even to use 4 tracks and 4 sample decks total? I really want to start getting into doing a dual dj set with him so any information that could help us figure this out would be fantastic. Thanks Guys
