Reply to Where to go from Kontrol S2?

Hi guys,
I currently play on my MacBook and the NI Kontrol S2. I have it mapped
Out and enjoy using the jog wheels for effects etc. I've recently started getting gigs and I believe that I really need to be using the CDj's or vinyl decks and mixer in the clubs. Firstly as it is hassle for everyone for me to get the Kontrol setup, it would be so much easier to be able to plug my laptop in and go with what they have there.. Also I believe it looks more professional than the kontrol S2.Also I gave noticed the volume that comes from the Kontrol doesn't seem to be that loud. What are my best options? Ideally I would like to continue to use traktor.any advice would be appreciated.
Cheers,
Austin
