20ms is way too high of a buffer lower that to 5. The lower you have the buffer the better the controller responds to movement. You want low latency. 20ms won't help.

Hey there,

Regardless of the buffer you shouldn't need to disconnect to have the play button working correctly. Please open up a help request from the link below and we'll look into it.

Cheers.

Thanks to DJ Tecniq and Jordan L.
I am going to apply all of your advices right now.

What Firmware do you have?

Sorry, what is the firmware ? The OS or the version of SERATO?

firmware is for the controller however the SB2 doesn't need firmware so something else is going on.

Exactly. Thank you.

Did you lower the USB buffer? Is the controller not able to scratch?

Yes DJ Tecniq,
Thank you, I did it to 5ms.
I scratch but I don't know when I will have the problem.
I can scratch and mix an hour long, and then plaf

That's odd but to rule this out have you tried an early 1.9 version like 1.9.5 or below?

Sure I didn't have that problem before.
May be a downgrade would be the solution.
Support team sent me an app to record serato and controller activity. I'm on it.

Would you please show me how to do a downgrade of Serato?

Hi Mark,

It seems like I'm having the same issue as you are - randomly the right deck will stop. Play button shows a solid green light, play button on serato shows that it's playing, except it isn't. Pressing the button gains a response from both the device and serato (play button light flashes on device and serato responds accordingly) but the music won't play. Scratching works, as does holding the cue button. If I switch to deck 4 i am able to play music, although I can't scratch (as if the vinyl emulation has been turned off) - I can only pitch bend with the jog wheel. I can sometimes mix for over an hour without the problem popping up, although other times it will occur numerous times within half an hour. If you roll with decks 1 & 4, deck 2 will sometimes kick back in to action after a while.

I'm not sure if you've had a response but I thought I'd share since it sounds pretty similar to my problem. Tbh it seems mine is likely to be a hardware issue as I have this issue in dj intro, dj (trial) and rekordbox (trial), and have also tried different USB sockets and cables, as well as trying to play music only from the hard drive (I.e. Not an external hard drive) and keeping the trim down (suggested by a friend, although I'm not sure why).

Hopefully you get sorted, or the above may be of some use to you/ serato!

@The Ferg - sorry to hear that you're running into similar issues as @Mark Asseh DJ - are you using a DDJ-SB2 as well?

Have you had a chance to get in touch with us via a Help Request? If not, I recommend doing so with a video of the issue you are describing above, log files of your most recent SDJ session where you encountered this issue and your computers system report file.

Hi Dave,

Yes, I am also using a DDJ-SB2. I am going to open up Serato now and start mixing and should hopefully get the report and log file I need to submit a help request.

Hi everybody,
Im so sorry i was off all that time.
Didn't give you any feedback.

I found the problem: my power adapter cable was defectuous.
I changed it.

Now it's fine for this issue.

@ferg, now my problem is yours. This is happening to me plus the fact that after a hour of mix sync goes mad!

Thanks all of you!!!!

I just want to also say I was having this same issue. My issue was because I had the USB cord plugged into the back of my Thunderbolt display, which was then in turn daisychained into another monitor and then only finally to my Mac.

Plugging the USB cord directly into the mac fixed it.

So, most likely USB protocol issues that were degraded by multiple connections were involved.

Advice, make sure you're directly connected to your computer's USB port.

Hi everybody! I just found this and i have exactly the same problem, same deck (right) and same laptop. In my case i have a Pioneer DDJ SB L mixer, and i cant find a solution for the issue. Does somebody have a concrete solution for the problem? I have tried to plug the mixer in both USB connectors, but no difference. Sometimes happens, and sometimes not, and there is no power cable in this model, just an usb to the computer.

Im running now serato pro 2.0.1

I've figured out why my controller is playing up.
I grabbed the plastic non conductive edge of the platter, then twisted it a bit. It somehow paused the track. When I experience the issue whist using the controller I do what I just said to get the play button to work again.
I think it's all down to the degradation of the grease that is used on the shaft of the decks.
I swapped mine around and the problem switched sides.
I then cleaned all grease off and the issue got even worse.
Try cleaning yours and add some fresh conductive grease.
Have a look at this:

When I DJ my left deck play button usually stops while playing and I don't know why at all but it really pisses me off.

Inspired by the "hold hard down on the platter" solution - which actually kind of worked - progressing from there, I found an odd succession of
1. Get out of vinyl mode, press VINYL to go back to standard/CD mode
2. Continually hitting the PLAY button while jiggling/scratching the jog wheel above, around, can swing the deck back into PLAY action. Don't need to press hard, avoid damaging your deck unnecessarily.
Would like to know what the actual solution is, haven't time to search everything, is it a firmware upgrade or just a known issue (that I've been plagued with for years) that will never get solved? Sending in support tickets doesn't help the rest of us who quickly need to search and find the definitive solution. Many thanks J
