No problem. Like I said if Traktor is your cup of tea and you are sold on it, then the S4 will give you all its features. But even though the jogs are the only jogs that traktor is really tight with (apparently the 4Trak has similar tightness) do not expect to get a single scratch routine off, as I found the jogs to be a horrible design.
If you want to get really highend and use traktor, you might checkout the 4Trak by Numark. I heard it has really tight jogs with Traktor and all features, except Remix Decks. If it is the same quality as the NS6 I used, this unit is the endgame! But then it is also a lot more expensive than the S4 again (but prolly worth it).
If you want Traktor but are OK with “kinda good jogs” (do not get me wrong I still got of a scratch or 2) the Digital Jockey 3 by Reloop is a reasonably priced unit, but you have to add a few bucks for a full version of traktor. If I would still want to use Traktor, I would have bought it.
