DDJ-1000 skips loop engaging

What is it you mean by "skips" loop activation? Can you post a video of this for us to understand better? Thanks.

I've also had this issue for a long time - when you do a loop using the in-out buttons, sometimes the track will actually ignore the loop and continue right through as if the loop wasn't set, but if you look at Rekordbox and even the DDJ-1000 screen, Rekordbox actually thinks it's inside the loop. I've seen this happen on Rekordbox on my Mac and both of my Windows PCs.

It's definitely trainwrecked some performance routines I have where I hot cue juggle a vocal before a drop and do short manual loops, since if the loop get skipped the track goes straight into the drop (not fun). As a remedy I save short loops to hot cues if I know I'm going to be doing that and also haven't seen the issue with saved loops or the 4 bar auto-loop, so I think it's some timing bug with manual loops.

However I've noticed I no longer run into this since updating to 6.1.0, so I'll update if I see it again. Either it got fixed or I've been super lucky lately.

If you can provide a video, that would help us diagnose the issue. Thanks.
