Follow up. I still have no luck! I have updated the Prime and even checked updates for my VDJ.
VDJ works fine on its own or when connected to my Numark mixtrack quad or my Pioneer. I have spent 4 hours and all the i structions dont make any sense. Checked the wedsite and it mentions some usb drivers
“Download the dedicated driver from the “Download” section of the DA-10 page of the Denon website onto your PC.”. No link to the site. Searches bring up a product called DA-10.
First experience with Denon is turning out to be my last! I simply cannot trust these units for a gig!
@kradcliffe I think you may be right as it started working after i uninstalled and reinstalled everything. I also changed the USB port i was using and restarted the laptop. Not sure which bit made it work but you may be on the money.
