XDJ RX skip beat issue

Just to add to this and I’ll try my best to keep it simple.
Practiced my set last night from my playlist and it skipped in exactly the same tunes and near enough the same point. Track A which was playing is 120bpm, track B being mixed in is 189.99bpm. Both were synced at 120bpm. I took both out of sync mode and track B was fast. I had to slow it down to 192.2bpm for it to be in sync with track A, even though that was still playing at 120bpm. Re syncing wouldn’t solve the issue, track B would still be playing fast when I took sync off. I turned it off, plugged my usb in to my laptop and checked the tracks in question then tried again. Track B was back to normal.
I reanalysed the track in rekordbox (I’ve upgraded from 3.1 to 3.3) to see if that made a difference and did my playlist again and it didn’t skip in that mix. It did skip in another mix a couple of tunes later though. Again, it appeared one of the tracks was fast even though they were both playing at the same bpm. It’s as if I need to play a handful of tunes first for the RX to get itself in a bit of a tizz and then read a bpm wrong on a track.
I did another practice and I’m resyncing each tune as I load it in (mix tune in, turn sync off both tracks, load new track in to mix, turn sync back on). I did a little practice and didn’t get anything, will try full set tonight to see. Would be nice to know if anybody has any ideas. If resyncing works then that would be great, small annoyance but nothing major. Fingers crossed though.

Hold on, one track was 120BPM and the other was essentially 190BPM? Why are you mixing two tracks so far apart in tempo and expecting one of them to sound anywhere near decent when being pitched so far? Skipping aside, I'd say the problem is the track selection! ;)

On to the skipping problem itself - if you play that one track (just one track playing), does it skip at the same point every time you play it? Does it skip within rekordbox at the same point?

Damn it, I knew I'd mess the description up! I don't know where I got that BPM from, I was at work trying to do two things at once when typing it out....that's my excuse anyway :)
Track A is 120 bpm, track B is 118.99 bpm. Both were synced to 120 bpm. I had to slow track B down to 119.2 bpm to sync with track A that was still playing at 120 bpm. There's no skipping in rekordbox, they don't skip if you play just one track at a time or everytime you play them. On these two tracks though I'm pretty sure that when it does skip it skips around the same point. I'm mixing them in from cue points and I'm now convinced that when it does it it does it at the same point.
Anyway, I had a practice before doing what I said, reapplying sync as I went along. Was all going swell and I got past the tracks mentioned then it did it again on another two. Track A was just playing along and track B was in a two beat active loop. Track B just skipped by one beat so it was off. I took sync off to see if it was too fast or two slow and it wasn't, it just seemed that it had decided to skip for whatever reason. So it sort of blows my idea of it reading the bpm wrong out of the water I reckon.
I remember it skipping on these two tracks before. I was applying filter at the time on both occasions. Can't tell if it was the same point.
I might be imagining it but sometimes I'm sure I can hear some sort of latency when I'm mixing in, just some sort of clicks and pops. I don't know if this is just residual fear left over from my laptop days though!
I'm putting my tunes on a new usb and reanalyzing them, clutching at straws really. Thanks for the response Pulse.

If you're able to catch it on video or consistently encounter the problem, that would help me pass the info along to the engineers - otherwise it's like trying to nail soup to the wall. ;)

I can imagine. Cheers Pulse, I'll try and pin it down and record it. I'm going to reanalyze all the tunes in the playlist and keep my fingers crossed in the meantime.
