Well the only things the S4 has going for it is features that NI intendedly has locked out to other manufacturers.
If the remix deck functions, DVS function, sample recorder and high-res jogwheels would not be simply locked down to the S4, the unit would not be considered by anyone in their right mind for this price point. I am sorry.
Even the digital jockey 3 has a better build quality, the VCI-400 would be much better at anything hands down and even the highend Hercules would give the S4 a run for its money. Even the VMS2 has a better sound quality than the S4.
The ONLY reason for this unit existing at this price point is, that it unlocks features in a software… and for this is hugely overpriced. Of course if you are locked into traktor you might have to bite. I mean compare this to the VCI-380 that does also unlock Itch, but compare simply the built quality… The S4 has (if at all) the built quality of a Numark N4, put 80 bucks on top for the Traktor software and you would have a winner, again if the features would not be locked.
I am sorry if this sounds like a rant, but since I have gigged with an S4 for over 2 months I feel entitled to post my honest opinion on that unit.
