Denon Dn-s3700 Traktor Scratch Pro

So i just bought myself some denon dn-s3700's, but i havent bought a mixer yet. I want to use the denons with traktor scratch pro, mainly because i all ready own it. But if there is no easy way to get everything to work without timecode then ill look into scatch live.
Here is a video that shows two dn-s3700's working in traktor.

Now the question is, do i need to buy the Dn-x1600 to use my s3700's in traktor without timecode.
-How well do they work in traktor?
-What are the benefits of using hybrid midi mode instead of timecode?
-How hard is it to get midi mode working on either traktor or serato scratch live?
-Thanks for all the help!

Feb 12, 2018  For this week's Video Friday, we have World Renown Turntablist UK DMC Champion JFB testing out the scratch performance on the Denon DN-S3700 media players. These are actually my personal DJ Decks.

This mapping is an edit of mclub7's v2.1 hybrid mapping for the S3700. The mappings are tailored to my setup but the comments are all well done so if you sort by them, it should be easy to edit the mapping if you would like to change any of the buttons.Scratch
It is for 2 decks (A & B) in the Denon Hybrid-Midi mode. This uses a built-in time-code signal in addition to a midi mapping layer. That means that to take full advantage of the midi and the hybrid mode at the same time, you would need to have Traktor Scratch Pro and a scratch-certified soundcard (NI or hacked) as well as the hybrid midi firmware that is available for free from Denon. All controls are explained in the pictures included.Denon Dn-s3700 Traktor Scratch Pro
Let me know in the comments if you have any questions.
