[CLSOED] CDJ 2000 Nexus reverse problem

I'm not in front of a computer right now, but I'm pretty sure he was doing the reverse within slip mode, in which case it will always be on beat on release.

Sorry I forgot to mention that Slip mode was on.

There is a known issue where the reverse seems to lag for a second or so. That could be what you are experiencing.

Thanks guys, I'll check this out.

i've found that occasionally while in slip mode messing with the reverse it sometimes seems to loose being in sync, the tempo it was in, and slip functionality, meaning occasionally the one deck we have pops off the tempo and looses it's "sync" completely jumping to a new bpm and sounds like both slip and quantize wheren't on, when they where to begin with. not cool! good thing this is home play and getting used to the gear and not at a show cuz gotdamn would that ever look worse then it sounds on my home monitors, and i don't think it would sound better on a proper pa system...

we're still on firmware 1.06 due to all the negative stuff i've been reading about the 1.10 and 1.11 fw updates...

is this a problem with the deck itself or a problem with the fw? i've tried recreating it but it seems to choose when it doesn't want my mix to sound good, which is not cool by my standards.

p.s. Gavin, u rock! from what i've been seeing your one hellluva helpful person!

Sounds like you're having the same issue as the rest of us in slip mode.  There's another thread open where it's addressed by the mods - evidently on the current FW, there are certain instances (for example, after hot cues have been used) where if you engage slip and then engage a feature such as slip roll/loop, reverse, backspin, etc on player, the unit may not actually slip and you'll be in real time which will throw off your phrasing.  In my experience it's been somewhat unpredictable - I'll rehearse the same sequence of actions multiple times and sometimes it will slip, other times it won't.  Hopefully they find a fix for it.   

Ok, checked this out:

First, I tried it with the sync turned off. Engaged slip mode. Played the track the two tracks - both were perfectly match at 120.00BPM. Turned on reverse for about 10 seconds, then turned it off. Both tracks still stayed perfectly in sync.

Second, set one track to 114BPM and the second to 122BPM. Turned on sync and slip mode. Played both tracks. Engaged reverse on both tracks at different intervals for varying amounts of time. Both tracks stayed in sync and played as normal.

I also tried this on both decks without using slip mode at all and just sync - everything performed as expected.

Also tried this with firmware 1.06 and 1.11 - same results both times.

Thanks for checking this out Gavin.  My experience with the issue has been very random and difficult to reproduce with any consistency.  What you (or maybe Pulse) had mentioned in the other thread rang a few bells though - made me recall two instances where it happened with a track that was mixed in using multiple hot cues.  Both instances were with different tracks, through both were MP3s.  In instance #1, sync was off and I used slip roll within say 30 seconds of hitting the last hot cue; the result was as though slip had not been engaged - loops functioned as real-time loops would.  In instance #2, sync was on and I backspun with slip engaged say 2 minutes or so after hitting the last hot cue; the result again, was as though slip had not been engaged and the backspin sent me to an earlier point in the track.  Can't say I've experienced the issue w/reverse.  Hope this helps!  

@Fox > Ok, I think I actually managed to reproduce this... I can't remember the exact details but it was something like this:

So I had used sync to match both my tracks and once they were matched I turned sync off again - but I didn't move the pitch slider (so in essence they were still BPM sync'd).

Press play on the track with hot cues and then pausing it (even with slip mode engaged) meant the track stopped playing - totally, slip or no slip. With the whole track paused I moved the pitch slider and the slip mode jog indicator started moving again.

I haven't been able to reproduce it with any consistency - I'll keep trying though. So what I'd say to you if this happens again is quickly move your pitch slider to "un-sync" the two decks.

Interesting about the pitch slider. Unfortunately for me, both times this happened live I was running acapellas in slip mode over instrumentals on another deck (this is when I most often use slip). So when I engaged a slip loop for example, the underlying instrumental would keep going but the acapella didn't (ie since the track didn't continue to 'slip' beneath the loop), so when I came out of the loop the phrasing was off...woof. In that situation, by the time you realize slip isn't functioning, it's too late to correct.

i honestly think its a bug in the one deck's reverse. only seems to happen in deck1 so far as i can tell and it's NOT consistent.

it is while synced and in slip mode, nothing touches the pitch or ANYTHING else cept maybe the loop rolls...

it's only happened three times but thats enough to make me weary about utilizing the feature in a proper performance.

don't get me wrong the slip mode makes me super stoked on these decks(amongst many other features) but it scares me when devices don't behave as they should....

i don't understand how hitting the pitch slider to knock it out of sync is going to help this when my issue seems to be it loosing sync already and making a drastic tempo change thusly creating the worst mix ever.

@fahlawfulls > I'm not denying its not a bug - I'm simply pointing out that its hard to reproduce consistently (if you can, please let me know how). Moving the pitch slider isn't an answer to this issue - its simply a quick fix to get the underlying track moving again. It has been reported.

ya i was kind of writing in hopes of finding out the cause of it myself. i don't know whats doing it all i know is it seems to suddenly pop out of being synced up, like it looses the tempo it was at almost like i turned off sync and/or hit the tempo slider so it drops out of the synced tempo and back into whatever tempo the slider was at, making the train wreck of doom i personally havent been causing in over 9  years, only i haven't been near the side of the deck with the tempo slider when it happened?
