Reply to Do I need a Soundcard for the S4?

Hello, I'm just getting into DJing and I've just recently picked up a Traktor S4. So far I'm loving the bits out of thing as I'm starting to learn all of the ins and outs. I was wondering if an external sound-card would be necessary for the S4. Other than more inputs/outputs/mic-hookups, I believe Traktor said that the controller has the same sound card that the Traktor 8 uses. Is a sound card necessary for gigs? To reduce latency?

Thanks
Andrew
