Topic: Pioneer CDJ 900/DJM 800 sound metallic when using different outputs
Hello,
my setup consists of two CDJ 900 with a DJM 800 in between.
The CDJs are connected to a USB Hub that is connected to a Laptop running VirtualDJ (should be the newest version) and via RCA to Channel 1 and to Channel 4 (not important for the problem) of the DJM using the CD/Digital respectively Line/Digital.
Now I have a strange problem:
When I set VirtualDJ to use different outputs for the CDJs (I am using ASIO and CDJ-900 1 L & R/ CDJ-900 2 L & R) the sound on channel 4 sounds metallic. On channel 1 everything is fine.
When I set both to use the same output (either channel 1 or 4), everything is fine aswell.
I don't know whats wrong?? I also tried using WASAPI (using CDJ 900 (WASAPI) and 2-CDJ 900 (WASAPI) and chan 1 & 2 for both) but get the same result.
I also reinstalled the ASIO drivers.

Thank you for any help!

It does not. This is about the HID via Link connection, that, as also stated in the article, is not available on a DJM 800...
Also it should work the way I have it now, I just don't get why it doesn't..
 
 
Really?? Did you read anything of what I wrote? This is exactly the setup I currently have...
 
I read every word even watched your videos and looked at your screen shot maybe you missed something there never hurts to be sure besides its something to check until someone with a better answer comes along :-)
 
It sort of sounds like if your audio buffer size is too small for your computer to handle (remember it's pushing to two different soundcards now instead of one in this config which probably = two different audio buffers)

What are your latency settings?

If you have ultraLatency on, perhaps switch that off, and check your latency setting = the CDJ soundcard setting (256 samples) to start with, and then maybe keep increasing it by powers of 2 to see if that distortion goes away?

Also, make sure the sampleRate setting is set to auto or at least matches what the soundcard expects (from your screenshot it looks like 48kHz).
