I felt like it was worth starting a thread for this, instead of taking over another one that is not exactly related. Way to reproduce the problem is to set up a cuepoint in CDJ, starting the track, backcueing, starting the track, backcueing... repeating this a couple of times shows that on 1.2.1, the cuepoint isn't "accurate". The audio playback starts from "somewhere near the set cuepoint", but not exactly from it. In 1.1.2 this was still working. Apparently (based on my own experiences) the accuracy is slightly better when using the timecode control in "absolute"-mode. Furthermore, it seems like the accuracy is best while the CDJ is in "vinyl"-mode (for whatever reason). For reference, the same problem is discussed in (at least) these threads; more precisely on others (on some I've only taken an educated guess that the problem might be the same as the one I'm describing): play from cue + timecode + cd Relative Mode TSPro- 1.2.1 ... slight lag in audio KEY LOCK search problem 1.2 track cueing flimsy 1.2.1 Cue Point Delay Issue on CDJ General Problem with CDJ's Inconsistent Cue point TS DUO with CDJs There is a possible workaround. I personally haven't had the chance to see if this solves the problem, because I only came upon it by going through the earlier posts... By what people have been posting, apparently if you disable "key lock" on Traktor, the problem goes away. Of course, since the new keylock algorithm is the single best feature of the latest version, I don't consider this a good alternative. This prompts me to believe that the problem is some kind of a bug with the new algorithm implementation. Edit: I'm not exactly sure if this message should have been posted on the "technical issues"-subforum. If moderators think it would better fit there, I don't object to moving it there.
