Reply to learning CDJ from s4 for a small gig

hey guys,

Ive been learning and playing on S4. I might be able to play in about a week but the venue has CDJ and they would want me to use them so that there is no commotion before resident dj.

How long does it take to learn CDJs? I am going to be playing deep tech house. i will probably have 2 hours on the weekend to practise on friend's one. Maybe you can send over the tutorials for basics?

cheers
