Reply to S4 for Mashups?

I'm not too familiar with DJ controllers and software, I have a bit of experience with turntables, used to have a pair of 1200s and mixer but was mostly into tablism, had to sell all my gear for school though. Now I'm interested in getting back into DJing and a bit of production, just wondering if the S4 would be suitable for creating mash-ups.
Cheers
