NS6 with El Capitan and "Beta" driver Serato

Hello,

I recently upgrading to Sierra on my 2011 Macbook Pro. I can provide the specs if needed, however, this shouldn't be a reason I am having issues.

After upgrading to the latest OS from Mac, I downloaded the "LATEST" driver on Numark's site for Sierra and my NS6. After confirming everything is at the latest update, I began having an extremely high pitch /distortion sound after approximately 15 mins of use, the sound resembles a high pitch filter and i heard on both decks, (1 and 2). I power cycled my Mac, the NS6 and then AGAIN after 15-20 mins of operating, the high pitch filter sound came back. This issue is UNACCEPTABLE for any professional event that I am charging a fee for, I actually had to refund a portion of my fee because the issue kept coming back every 15 mins after I would restart the software.

My NS6 was ROCK SOLID for years when I was not using Sierra, so I made an appointment with the Apple store to "devolve" my Macbok Pro back to the previous OS, I assumed if I went back to the OS that was rock solid, and never gave me one issue with Serato, I would be back to "issue less" performances, WRONG! So I am performing this weekend and about 1 hour in the performance, that horrible high pitch sound came back.

I perform approximately 70 weddings. club gigs, private parties a year and cannot have my gear fail on me! I have no confidence in my NS6 right now and I am respectfully requesting Numark provide a solution. Any true professional understands the anxiety that comes with gear that fails and it had been frustrating the past month with this continuing issue.

I am determined on getting this resolved with Numark and if needed, will escalate this to everyone to understand the severity of this.

respectfully

  • Hi Jesse,

    Thanks for posting. Sorry to hear you're having issues with your NS6.
    You'd mentioned that, "if I went back to the OS that was rock solid, and never gave me one issue with Serato, I would be back to "issue less" performances".

    What operating system did you downgrade your Mac to where you're experiencing the same issues as you were on Sierra? Do you have a Windows machine that you can test your controller on, as well?

    Sometimes, a simple uninstall and reinstall of the driver can resolve issues like this. If this doesn't, I would like you to please try the following:

    1) I highly suggest you optimize your computer for use with Serato DJ. click here more information - Troubleshoot USB dropouts / audio glitches (Mac).

    2) Sometimes removing the device from MIDI Studio Window (Mac), lowering the Maximum Screen Updates Per Second (Windows & Mac) in Serato DJ and adjusting the USB buffer settings improves the symptoms that you are having, and in some cases completely resolves the issue. See the steps below.

    Removing a Device from MIDI Studio (Mac Only)
    1. Open a new finder window and navigate to Applications > Utilities.
    2. Double click Audio MIDI Setup.
    3. Select Window from the top menu and click on Show MIDI Studio is checked.
    4. With the Numark controller disconnected, click the Numark USB Audio Device.
    5. Click Remove Device from the top of the MIDI Studio window.
    6. Under the drop down menu, select New Configuration.
    7. Type of the name of your New Configuration. Ex: Numark Controller.
    8. Reconnect your Numark Controller.
    9. That’s it.

    Lowering the Maximum Screen Updates Per Second & Increasing USB Buffer Size (Both Windows & Mac)
    1. Open Serato DJ.
    2. Click Setup from the top menu.
    3. Click the Library + Display tab
    4. Adjust the Display slider to 20 or 30. If you still experience clicks and pops after setting to 20 UPS try lowering the slider.
    5. Click the Audio tab
    6. Adjust the Audio slider to 10 or 20. If you still experience clicks, pops and dropouts then set your latency settings to 20.
    7. Close the Setup.

    3) One of the most important files used by your Serato software is the database V2 file. This is stored in the _Serato_ folder in the Music folder on your internal hard drive, and in the _Serato_ folder on any partitions and external hard drives that your Serato software has accessed.

    The database V2 file stores your library information such as whether a track has been played, whether a file has had its overview built, which tracks are corrupt, which tracks are from your iTunes library and much more.

    Unfortunately, sometimes this file can become corrupted, and you may notice odd behavior with your library. Symptoms of a corrupt database can be green "played" files not saving or ID3 tags being re-read every time on startup. Creating a new database V2 will fix this and is easy to do.
