New DVS Issues - 5.2.2

Bug Reports
30

Hi @Slak_Jaw,
here are some update, I have recorded control tone, and made a Stop time test on Mac too. I have to say that, on Mac stopping behaving works so close as real vinyl, but on iOS (iPad Pro) doesn’t, similar, but not same as on Mac, on iOS, in there is some annoying differences in stop behaving.

Here is the link to download zip file.

Thanks for the recording @DJ-Z.

  1. Are you using the same Stop Time in seconds on iOS and macOS? This setting is found in Settings>General/PLAY/PAUSE>Stop Time.

  2. Also, did you run the same calibration and use the same Sensitivity settings on iOS and macOS?

of course, all settings are same on Mac and iOS

Excellent. Thanks for confirming

Hi again @DJ-Z, engineering reviewed your DVS signal and everything looks good there.

  1. Stop Time: can you please try turning OFF Key Lock to see if that helps?
  2. Accuracy: can you please more clearly explain this issue, including a picture of the calibration info, a video of it happening, and if you’re using a different piece of DVS software, also a picture of those settings and a video showing how that behaves. Engineering hasn’t changed the DVS code in over a year so they think something else must be contributing to the issue you have observed. Therefore we need to more clearly understand your specific issue in order to help you further. Thanks!

Also, have you read the PDF in the linked FAQ article below regarding turntable calibration in djay? Perhaps this will help:

Hi @Slak_Jaw

• I have tried, that Key Lock, if that have OFF state, stop time works as should be on iOS.
• I have made 1 hour ride live stream, the accuracy is recurring issue, as I mentioned before, and very hard to tell whats exacly wrong with it, but it is a disaster, and I have to say with my full respect, DVS is not done, that is still in beta, not work as should be!!
• Also, if CFX is on, for example Deck 1 run, on Deck 2 next song will play and you want listen into the next song, and you can’t! I was so surprised, there was no sign in led meter, that was full muted. it looks like there is no signal…

Its very annoying, after DVS feature have released, just I’m sorry for that, but worse and worse…

Check here, and sit down :slight_smile:

Yes, I have read the PDF and I have set up calibration as in instruction, some times on one of my control vinyl say signal is too loud, sometimes it seems tonearm too heavy…but I have the same (3g) weight on both turntable…

Hi @DJ-Z, thanks for the additional information and video. I’ve shared this with engineering.

  1. Stop Time: thanks for confirming that Key Lock OFF addresses the stop time issue. Please note that enabling Key Lock adds a latency of about 100msec. This is currently a known performance limitation that our team is already investigating (see linked topic below).

  2. Accuracy: I will report back on this after engineering has reviewed your video.
  3. CFX Headphone Cueing: this is a known limitation when using CFX that the engineering team is already investigating as well. Please see the linked topics below:

Also, I have noted
• Stop time: only the left (deck 1) turntable affect the running deck
• Accuracy (sensitivity): is it possible control vinyl has some damage or extra deeper dirt in the grooves, and those are affecting the accuracies issues?

Does the official control vinyl has any guarantee?

38

Thanks for the additional feedback @DJ-Z. I’ve shared this with engineering.

39

Hi again @DJ-Z, I spoke with engineering and the accuracy issues you are describing sound like your needle might be accumulating dirt. It’s also possible that your control vinyl is dirty or damaged. For details regarding the control vinyl guarantee, please contact the retailer that you purchased it from. Thanks!

Engineering also has another thing they would like to check: Can you please capture a video of what the circle scopes in the settings are doing while the issue is appearing?

So appreciated @Slak_Jaw to getting back to me and making effort to help. :pray: I’ll try to do some extra cleaning or washing the record, then update you soon!

You’re welcome @DJ-Z

Hi @Slak_Jaw

So, I did extra clean on record (Washed) and needle (needle gel, brush), it seems now okay…shape of the scope also fine.
but I found another weird behaving, I don’t know it s normal or not, but to me I have to say its not a normal behaving. I feel this is the bottle neck of the accuracy issue.

45

Hi @DJ-Z, glad to hear that cleaning your equipment helped. I’ve passed your new video onto engineering.

46

Hi @DJ-Z, what you’re showing in the latest video is nothing to be concerned about. Any unterminated cable will act as an antenna that collects whatever electromagnetic interference from power lines and other electronic devices is naturally floating around the environment. By plugging the other end of the cable to a turntable and connecting a ground wire between turntable and mixer the open connection is closed and thereby shielded from this type of outside noise pretty effectively.

If you have any other issues/videos to share, please also show the calibration scopes in the djay settings. Without this, it’s very hard to see what exactly is going on. Thanks!

48

The naked €2 RCA cable move the waveform in the app, I don’t think so that would be normal behaving! Have you seen the shot?

49

Yes this is expected. The software is interpreting the noise/interference from the ungrounded/unconnected cable as a poor DVS signal. Personally, I recommend you also consider higher quality, properly shielded RCA cables.

Always use shielded cables. You get what you pay for.

51

@Slak_Jaw , @Dysfunk_DJ

I’ve use original Technics cables of course, that is not a bad, even not a top one cable. This €2 cable I have just lend from my neighbor just for testing :).

Question: Slak how software can detect ungrounded cable as poor DVS signal if input not lead in to app? (DVS=USB, but if switch to Phono, app still detect as poor DVS signal)

52

Hi again @Dysfunk_DJ, yes, an open ended wire will “collect” noise that sounds very similar to a bad DVS signal (no matter how cheap or expensive the cable is).

Regarding your last question: this is also expected. The Xone 96 mixer always sends a copy of the phono input to djay, no matter where the channel switch is actually set. Thanks!
