Reply to Need help, first time playing on cdjs & serato tomorrow

My buddy said I could dj for a little while on his setup at this local bar. not wanting to turn down any chance to gain experience to play in front of people I took the offer. only problem is I've never actually played using either devices. I dont even know what kind of mixer he's using lol. Also ill be using an external hd to play my music.

But I just want to get the basics down, enough so I can do your basic mixing and not crash anything.

Not that it really matters but I dj using an s4 and Traktor 2.0, but beat match by ear.
