I need Help with my CJD 850. I have two CDJ 850 connected to DDM4000 with Virtual DJ. First I realised that when one deck is playing and I tried to load the second deck, the music stops. After reading through many forums, I managed to solve this problem without buying a new power usb hub. After testing for about 4 hours yesterday night, I discovered there are many flaws using CDJ 850 with virtual DJ. The major ones are;
1 - When one deck is playing and I press the Cue or Play/Pause button on the CDJ 850 on any of the deck, I lose the sound quality. I have to hit the buttons several times to regain the best quality.
2 - My cue points in my music cannot be seen by the CDJ
Could anybody please help me out with any of this problem.

There are a few threads between this forum and the Pioneer VDJ forum, the CDJ-350 and the CDJ-850 forum that discuss users having dropouts of audio and control -- Pioneer may have found the source of the problem!
If you are running VDJ Pro, this will be the only way you have to correct the issue - LE users don't have the appropriate settings (although I may be wrong on that, I haven't fully tested it with LE).
Go to your Config, select the Performances tab and where the Sound Card Latency probably reads "AUTO", change that to another value; this value will differ from computer to computer -- use the lowest setting is that doesn't result in hiccupping or glitches in the audio.
It would seem that in AUTO mode, the software tries to dynamically adjust the latency of the soundcard, but in doing so, can cause a disconnect of the driver and thus a total freeze of the controls and the audio playback will stop.
Please try setting this from AUTO to a fixed value and let us know if this resolves any of your issues with the 350/850 as soundcard/controllers for Virtual DJ.
Hope this helps,
Ian

Thanks for the reply. I read that in the pioneer forum and also in one of your post here but it still doesn't help. This was to solve the problem of sound cut but I am facing another problem where the sound quality diminishes when I press the Cue, Play/Pause button.

At least, are you using a powered USB hub ?
I think that your issue relies on this.
First of all try to see if the problem goes away without using a USB hub. Afterwards try a powered USB hub, and even if you're allready using a powered USB hub try another one.
It's not a secret that Pioneer CDJ's don't mix well with USB hubs, powered or unpowered. I would definitely go for a powered USB hub if I had to use one but I would strongly insist on connecting the CDJ's directly on my laptop.
PS: How many USB ports has your laptop and what do you connect on them?
PS2: Is there any chance you're using a USB3 port? Most USB3 ports while they claim that they are 100% compatible with USB2 they are NOT. Currently the only things I trust to connect on a USB3 port is HDD and mouse!

Thanks for the reply. Yes I have a powered USB hub which I am using. My laptop is Sony Vaio with 3 USB2 ports where one has been damaged and only two are available. On this powered USB hub, I connect 2CDJ 850, ddm4000, vms4 with USB mouse. I will try to connect them directly to my laptop and see if there will be any drop in sound quality.

That's way too much bandwidth for real-time audio... In worst case I would connect the 2 Pioneers (remember that they are HID devices) on one hub, and the rest of the stuff on another... That would put some stress relief on the bandwidth of the USB ports.
PS: Each Pioneer equals to 2 devices: 1 HID device + 1 soundcard.
So currently on your USB hub, the PC sees 7 devices connected all together (3 HID devices & 4 Soundcards)
