cuing music coming out of right headphone instead of left.

Hello Brendan,

Thank you for reaching out to us. The reason that is happening it's because you have to put it in 4 channel mode and then restaert the software again. Let me know if this helps.

Hi, My VMS4.1 reset in the middle of a gig and then the cuing was full of static. Next day I uninstalled both Virtual DJ 8 and VMS4.1 drivers and reinstalled them both. VDJ 8 1st and now I have cuing music coming out of right headphones. I have to pull my jack 1/2 out for semi normal operation, Is this a known issue that can be fix using the support # or does it require repair? I purchased my VMS4.1 9/27/2014 and I recently started having other issues like, deck 1 sync and cue 4 button is unresponsive which could be the VDJ 8 software but the resetting has happened twice now. Please provide feedback on next steps? Thanks, Troy

Hello Troy, 

Thank you for reaching out to us. The resetting can be caused by a power issue or bad USB cable. Make sure that the correct power supply is being used (5.9 – 6VDC 1amp) and try a new USB cable. As for the headphone issue, try a different set of headphones or cable. If the problem continues, then the product needs to be serviced. Let me know if you have any further questions.
