Reply to Kontrol s4 with serato

Hi, I am a proud owner of a Kontrol s4. However since I've started to get opening dj gigs at my local clubs I've noticed that they all use serato and provide cdjs or turntables. I would really like to move my collection over to serato just to get used to it and continue to use my kontrol s4. Is there any way that would work? Eventually I would like to invest in some cdjs or turntables but that is not an option right now. Thanks!
