After about 3 years away from DJing and working more on production and digital art, I now have time to get back into things.

I used to have a VCI-100 but never really got fully to grips with it as I'd begun drifting into other things. However, I've now skipped the false economy of buying cheap first and go e straight for the S4 (found a deal for 499 with the 140 flight case for free).

Anyway, what should I be looking for? It's arriving tomorrow and I now have more time to focus on DJing. Any tips for a relatively new (again) digital DJ with an S4? Best mapping, tips etc?
