Native Instruments Traktor S4 MK3

I was stuck between the Numark NVII and this. If you've used CDJs or other standalone decks and gotten comfortable with them, only then will you understand the feeling of limitations in controllers. The Numark NVII does a good job of trying to be CDJs, the built in screens are just amazing and mean you can keep laser focused on mixing instead of taking your head up to look at a screen. However, Serato seem to be the EA of DJing software - "we have the features you want, but it will cost you extra on top of the original purchase!" You have to pay extra for DVS, FX & filter models in a lot of cases so do your research!

Contrast this to Native Instruments and Traktor. They give you everything, for one initial price. DVS, a massive selection of FX - assignable to 3 tracks for each deck and also a mixer FX section where you have 4 FX switches plus an additional filter switch! There are a nice few filter models which can be changed in Traktor, which I recommend. On first launch, the filters will be the super smooth kind (Classic), go to the Mixer settings in Traktor and experiment with the other types. I recommend Z ISO, it has that sweeping magic resonance that we all know and love!
The Haptic feedback technology is really, really interesting. The torque is just like a turntable, no joke, it is. However, I haven't gotten used to it enough to be able to truly judge it.

Finally - the unit is really well built, it just has a premium feel. The lighting is well balanced and the controls and commands are more intuitive as you continue to use it.
The only issue I have had so far is sometimes the mini-screen for the waveform and track information just stays saying Traktor until I turn the unit off and back on (while Traktor is running). Reproducible bug and I'm sure it will be solved in time.
It's an extremely honourable offering. I'm just bummed I didn't grab it for €759 before it rose in price to €899!

I confess I ordered this controller because of the motorized jog wheels feature. The first unit I got, clearly had a left jog wheel issue that caused the music on Deck A (and C) to drag and skip on its own. Got a second unit from Thomann and this unit is now working fine (thank you, Thomann). The motorized jog wheels in TT mode are a lot of fun to DJ with, no doubt. I'm a bit old school and I love vinyl. The S4 MK3 allows me to have all the fun of vinyl without the hassle of having to carry heavy records in a trolley. However, the operation is not as smooth as you would expect from such an expensive controller. Playing using either TT or Jog mode, there are still few "bugs" that cause the software to sometimes not interpret the MIDI signal correctly and the Tempo glitches a bit making beatmatching not so accurate... A slight nudge of the jog wheel and the problem solves itself.
I think it might be a TSI problem... Maybe even a firmware problem. Not sure. I'll keep experimenting with TSI's and wait for another update.
One huge overlook from NI, in my opinion, is the lack of dust sleeves inside the faders. This made me anxious, so I improvised some external ones made of felt and mask tape. Although the faders are inverted and carbon protect, that doesn't mean that dust sleeves are obsolete... In fact, if there were dust sleeves, the faders would probably last even longer. Alas...
That said, the sound is amazing and very clear, the unit feels solid, although it's plastic, and, so far, I love playing with it.
Note: Mac Mojave users have to create a new account/user with admin permissions and download the S4 MK3 Firmware Update from the NI website using Safari to be able to update the controller firmware. Otherwise, it just won't work...

Very Good differences between MK2. Motorised Jog Wheels is very useful and fun. Didn't turn off since the day I start to play with this controller.
The channels meters much more detailed (3 yellows and one Red).
The quality sound is better then MK2.
DVS support included. Just use an Traktor Timecode Vinil with my turntables.
LCD display with the essentials for your mix.
Good construction material, more robust than the MK2.
USB port hub included in the controller for connecting other devices (in my case an F1).
Traktor 3 license included. I love the new key lock features, it seams to me that the sound become more "elastic".
Definitely a very good upgrade from MK2 (my previous controller).

For producers using Linux like myself, it's super great that it plugs and plays as a sound card, without any extra software or drivers on Pop_OS.

It's also very fun but a bit confusing to get to learn, but that's how everything is and learning is what makes life interesting.

Great product and only good words to the people of Thomann!

A thing for Native Instruments:
PLEASE MAKE A NATIVE LINUX VERSION OF TRAKTOR PRO 3
