Virtual DJ DVS vs Mixxx DVS Reloop KUT 

Your first test suggests to me that Mixx (and presumably some other programs) have a “latching” feature, where it can tell you’re trying to get two tracks perfectly aligned and will ever so slightly help you do so. The way to test this of course is to start a 10 minute track on both decks, not at 0% pitch, get them beat matched, start them both from the start and see if, once aligned, they stay perfectly aligned for the whole duration of the track, because if they do, that proves that Mixx is subtly helping you and VDJ isn’t, because there’s pretty much no way that 2 tracks on 2 turntables will stay that nicely sync’d for that long, without some kind of assistance.

Using DVS since Final scratch came out. Always an issue with keeping time. I will check out Mixxx to see how well it works&report back.

Not sure if you know this but it's not jst DVS on vinyl & turntables it keeps falling out of sync with but it does it even wen your jst using the virtual Dj software on it's own with your favourite tracks & your computer. sooo annoying.

Vr Dj is shite!
