CDJs and USB hub

[tech2400]

How well do CDJ 900/2000 respond in HID mode connected to a USB hub? Reason I'm asking , Like to use my X1 along with the cdjs. I have a MBA with only 2 USB ports.

They should be fine since the CDJs are powered and do not require any USB bus power. I have the same setup as you described and haven't had any problems.

Any audio drop outs, pops or clicks , I'm playing in a big club and don't want to have any mistakes. Defiantly makes me feel better that yours is good to go. I was questioning is for quite some time now

I've never had any audio issues with any device since I got my Air.

Are you familiar with setting up aggregate audio devices? Pioneer provide a mini auto aggregator on their website.

Yeah I have the aggregator setup , I did it already in the audio midi app on the air.

Not to thread jack. I'm assuming you guys use Traktor connected to the CDJs with a USB. Can someone please explain how do I come in mid set to someone using CD's (one channel at a time). And then how does someone else take over after me who is using CDs?

Here is the setup:
Traktor 2.6
Macbook Air
CDJ 2000 with DJM 900. I believe the mixer and CDJs were linked.

THis past week I had a guy come in and take over after me and when he put in the CD and switched over, he was having trouble selecting a song and switched tracks. 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.

for one don't unplug anything from a channel while its in use. that's very disrespectful since it can cause issues.

if you are using midi, ya can plug the USB cables into your lappy while the cdjs are still being used for CD and then hit midi once its done. works for me every time flawlessly on tsp 2.6.1 on win.

Plug both CDJs into your computer while they are in use with CDs, but do not press any buttons on them yet. Check that your aggregate audio device is set up correctly. Then when you're ready to switch, press LINK on the free CDJ and activate HID mode. This is when you must make sure your output routing is correct by looking at the VU meters(it may be reversed). If it looks ok, mix in your track and then activate HID on the remaining CDJ once it's free.

I've heard of this problem a few times. When switching back to CDs, the rotary track selection dial must be pressed in to select a track from CD. Once the dial is pressed in (and only then), the CDJ will switch back from HID to CD mode. Do not disconnect any USB cables until both CDJs are back in CD mode.

Thank you for the reply. I will try it this weekend. Cheers
