interfacing cdj 900, djm 900 with trakor

Traktor does not work over ethernet connection - that is a rekordbox only connection.

You will need to use USB cables from each piece of equipment to connect to your laptop.

ok is there anyway to get the "fader start" feature to work with traktor? and if im not using a computer what is the benefit of having the two players and mixer hooked to a Ethernet hub?

The ethernet hubs will allow you to connect the decks together and share one audio source (such as a USB stick) or connect to rekordbox software.

Yes, it should be possible but you'll need to map / assign the software to a particular piece of the hardware to engage it.

From NI website, user DJ dp pointed out the following:

Connect all the USB's etc.. up to Traktor.

Turn the Midi on on the DJM900

Go to Preferences / Control Manager / Add a device

Change 'In Port' to DJM 900 Nexus and leave everything else

Click 'Add In' button

Select 'Deck Common' / 'Flux Mode On'

Make sure the fader start button light is off, on the mixer 

Click on 'Learn'

Press the fader Start button so the light goes on

Click off 'Learn'

Change the interaction mode to 'Hold'

Change the deck assignment to which ever deck you want (Usually A or B)..

Hey Presto!

This should now turn the fader start button light on and turn the flux on at the same time..

still seeming to have trouble as the "flux" feature on traktor acts the same way as the "slip" feature on the cdj 900 where when deck is stopped track continues to play........ 

Sounds like you didn't get Flux turning on/off properly...
