I have my trustworthy Vestax for some years now... But I guess after windows 10 it started behaving strange - it wouldn't get recognized, so I had to restart my laptop.
I brought a new laptop two weeks ago, djed with it, and all was good. I updated to Windows 10 anniversary update (I don't know if that the reason) yesterday, and when i tried to mix something, I noticed non of the software is recognizing the Vestax, neither Traktor, nor mixxx, and serato says "connecting to Vestax vci" but doesn't go into two player mode. Traktor dj is recognizing the sound card but has no midi in and midi out on the mapping... What could I do (iI changed to serato firmware (from another Windows 7 laptop, who could see on the firm up midi in and out) just to check - its the same. The controller itself is definitely not the problem iI have tried it on a Windows tablet, on a Windows 8 PC and so on...
