Rekordbox DVS issues

Hi everyone!

Was looking some expertise on an issue I have with my rekordbox control vinyl.
I have a DDJ-RZ with a reloop RP-7000 TT. Cartridge I'm using is Ortofon Pro S.
Everything on TT is calibrated correctly. I've calibrated the DVS scope but the circles still look a little distorted. Although playback and audio is fine.

But the issue I'm getting is that the BPM is fluctuating on its own randomly about +1/-1 BPM whenever the vinyl is being played.
Its impossible to beat match as the song is slightly going slower and faster all the time.

Would anyone know what's causing this?
Tracking issuse? Or dodgy stylus maybe?
Or the cartridge im using?

I've raised the issue at pioneer and seems a few people have had this issue, although pioneer don't seem quick with an answer.

Any help would be appreciated, thank you

Regards

Are you using the Pioneer Control Vinyl or Serato Control VInyl?

Hi, I'm using rekordbox control vinyl.
Any other brand would send a different timecode signal and wouldn't work.

Are you having the same problems beatmatching using a real vinyl record?

FYI RekordboxDJ DVS also works with Serato timecode signal, that's why we're asking ;)

Yeah ive used normale vinyl and seems fine 😔

Oh serato control vinyl works on rekordbox? Sorry, my bad lol
I just thought the different signal applied to all brands lol

What is your soundcard latency. Only way I was able to replicate the issue was by turning my latency above a total of 11ms.

Also make sure your tone arm contacts are clean. slight ground hum or missing a channel will cause the same issue.

Also if your bass is coming through the platter and being picked up by the needle, itll cause an issue in any software.

Ahh right okay. I have it set to 2.2Ms.
I have a macbook pro i7. There's no CPU issues at all but I'll give it a try above 11ms in a minute.
So did you have the same problem?

Just tried it all the way up to 23Ms and still does the same.

Really strange 🤔🤔🤔

I had the issue above 11ms, not below. :-p

Ahh right I see lol latency isn't the issue then 😔😔

I will be honest man. Pioneer hasn't put any effort into the DVS portion of rekordbox DJ. I don't see stability ever coming out of the software in relation to timecode. Pioneer has always made it's money on CDJ and Mixers, and that will always be the company's focus.

Yeah Ithat's does seem that way. I've spent a hell of a lot of money on pioneer, yet they can't seem to fix an issue that a lot are suffering with.

I've checked everything twice over, so seems it is just a software issue

Is there any update on this? I'm having the same issues. Sometimes it works fine sometimes the dvs is all over the place! I didn't think this would be an issue, traktor timecode is streets ahead.

I've got my latency at about 5 and I've set sync to BPM not beat (BPM works much better than beat)

I've got it working better. Every song was all over the place last night. With the tweaks tonight I managed to have a good mix for about 15 mins then it started drifting, then the last couple of songs were back to being in time. Some songs would start fine then in the last quarter would just start getting faster? Really annoying.

Pioneer support sucks, I wish I would've researched more before I bought it now.

What version of RBDJ are you running? ENsure you have the latest update installed.

Are you using Serato Timecode or actual RBDJ Timecode vinyl?
Which audio interface are you using?
Have you calibrated the DVS properly?

Hi

Thanks for the help.

Here is my setup...

Windows 10, intel I5 2.20, 8gb
RBDJ 5.1.1
RBDJ TCV
x2 1210, DJM450 and DDJXP1
Audio selected DJM-450 ASIO
Timecode calibrated but will try it again

Yesterday. I turned sync off and tried to use them just using the pitch on the TT. I got both records in time. looked at the screen bpm was both saying 120.9.

The cued record then sounded a touch slower, I chased the slower beat down around -3 on the TT pitch before it settled again and was in time. Checked screen, both running at 120.9 again. After about 30 seconds of both records being in time the cued record was suddenly much slower and that deck was now reading 117.4?

I will try calibrating again later today.

Considering that I haven't seen these issues mentioned many other places, I'm thinking there's something weird going on.

What cartridges are you using and how are they set up? Have you tried replacing them? Also, what happens if you just leave the TT at 0% pitch? Do the dots stay stationary for the whole length of the control signal?

They are ortophon pro s, about 6 months old. I'd say I'm not a heavy user, once a week max. I have a record collection and there is no issues mixing normal vinyl or traktor timecode. I will re calibrate and try again this afternoon.

Concorde or OM?

If they're headshell mounted, and you either mounted them offset to emulate a straight arm or did it wrong, I feel like the distortion from tracking error might be able to cause this kind of problem....and those distortions are subtle enough that you might not notice it playing real vinyl.

Concorde, I think they were a pair already made up in a metal box.

I've calibrated again and it's been much better. Only once the mix was running about 128bpm and one of the songs jumped to 123bpm. When this happened I looked at the screen and 128 was
on the master and the cue had jumped to 123, sync was still flashing so should have been in time.

I switched sync off for a bit and managed to have a decent go without much issue. I'd like to use sync sometimes though just to give me time to play on the xp1.

What settings do you use in the dvs tab and also what sync do you use (beat or BPM)?

When you have sync selected do your songs run in perfect time? Mine drift out slightly.

If your songs drift out of time with sync selected how do you get them back in time? When I try to get them back in time using the turntable I really have to fight to get it back. Sometimes it just ends up a mess like galloping horses (I can mix vinyl fine)

Try updating the drivers and firmware for your djm450. You should see a natural fluctuation in pitch (+/- 0.03% on average), but nothing like this. I have tried replicating your issue. Currently, the only way I have been able to replicate it is by setting my overall latency well below what the cpu can handle.

I'm pretty sure you basically have to use tempo sync if you're using control vinyl.

FWIW, I'm also just guessing. The fact that you use a concorde means my throughts were wrong. And I haven't used DVS seriously in years because it just didn't seem worth it.

Thanks for the replies. The latency slider, how do you move that? Mine is stuck and doesn't move. The CPU meter fluctuates between a 1/4 and 1/2 so doesn't seem that high?

The shop I bought from have been good and are also helping me. They have given me some things to look at so I'll add yours to the list. After that they have said I can take my gear in and they'll take a look, after that they will get pioneer involved.

I wouldn't be shocked if I've done something stupid though. Thanks for the help, much appreciated.

To adjust latency,

Quit Rekordbox
Open the DJM settings utility
Click on the ASIO tab.

Just as an update with this. I think it's the laptop. I've disabled everything I can think of, I use the old smitten script and I'm not sure if it's a fix but I put the mixer in a certain usb port and xp1 in another and they seem to work better???

Also would using a blue wave form help things as well. Whatever I've done it seems to be running much smoother. Beat sync works ok, if it runs out of time if I nudge it back in then hit sync twice quickly to turn it off and back on it doesn't fight it and sits in time again. With a bit of practice it works ok.
