My wife is doing a lot of DJ-ing and has been using Traktor. We recently got her a new system and Traktor has been acting up (both outputs running into the same output channel). We think it might be the Core Audio but are also looking for recommendations from DJ's on what software they like to use the best.

We are considering Traktor 3.3, MegaSeg, DJ-1800 and Ableton Live. Are any of these good? ARe there others that we should consider?

Thanks in advance
