CDJs and USB hub

[ABee]

Something else I just thought of. What if both switching DJs are using traktor with a different computer? How would that work?

If the club has a DJM900 or similar mixer with internal USB sound card, the 2nd DJ can use that instead of the CDJ sound cards.

Otherwise you'll need CDs or USB sticks to do the switch smoothly.

Then when he would start a track it would also start a track on my computer. I think we pulled out one USB cord and it made a sound (which sucked).

Please someone post the correct way to do this.

When you browse in cdj2000 and you find the track you wanna play you need first to press the browse knob so that cdj2000 loads the track. While playing from cdj2000 using USB I have caught myself many times when searching for a track in different playlist (than the one I was playing) and once I find it I then hit play but the cdj would go back and play the track it was previous loaded. So once you switch from Link to CD, then find the track you wanna play, press the browse knob to load it, then press play.

I hope this helped, take care.

Tried it by pressing back button and then switching to CD. Same problem as before where it wouldn't unlink. I am thinking of mixing in a track on my iPhone thru a different channel and then pulling all traktor USBs out. I just hope it won't make any noise and that the next DJ won't have any link problems. What do you guys think ?

What exactly did you do when trying to switch to CD? You need to press DISC (not back) and use the rotary browse dial to choose a track from the CD (push it in!).

It works fine on my CDJ2000s next to me right now.
Edit: you have to wait a second or two for the CD track to load before pressing play.

Basically the track plays but at same time the deck on traktor plays as well. It happened once when it wouldn't let me select a track on the cd. Even if the cd plays eventually I have to pull the USB (traktor wire) out. So the problem here is that the CDJ remains linked with traktor. I can't unlink and if I pull the cord then it makes a noise.

Pressing the browse knob in when selecting a track on CD, SD, or USB stick should deactivate the HID control in Traktor.

Are you using Advanced HID (not MIDI)? What Traktor version and CDJ firmware version are you on?

Makar, really appreciate the help. I'm on traktor 2.6 and was in HID advanced mode. Not sure of firmware on the CDJ will have to check that on Saturday.

If you really can't fix it, use the DJM900 soundcard for Traktor. That way you can use the hardware switches on the mixer (above the gain knobs) to change from USB to CD mode without any risk.

To better understand this, each CDJ is connected with Digital IN on the back of the mixer so if I wanted to play it normally I would switch to Digital (above the Trim knob). Now when I'm Using Traktor connected to the DJM 900, then I would rotate the knob right to USB. And Traktor is able to communicate with each CDJ via the Digital wire. Is that correct? I would not have to press link at any time?

I believe the red/white RCA wires on each CDJ are connected to a Serato sound card in case a serato DJ comes in, but I think those wires are wired into CD line on the mixer

Now when a new DJ would be coming in, I would choose an off-air deck, turn the knob back to digital from USB and then insert a CD/SD/USB.

Does that theory of a workflow sound right?
