M-Tack Quad Interference at 140 secs, into recording with Studio one

Hi,
I have a crackling/interference using my M-track Quad with Studio one when the recording gets to approx 140 secs.
I have eliminated the fridge, Central heating system, computer, channel 1 ( it was the same in channel 2), guitar amp and different mikes.
I then used my guitar directly through an iRig, into the same Macbook pro Retina, i7 3.0ghz-8 ram, 512 SSD memory and it worked fine with no crackling/interference, so it can only be the M-track Quad.
Can anyone help please?
Regards
Steve

  • Hello Stephen,

    Thanks for posting. Happy to help!

    Do you have any other DAW software you can test with?

    Are you connected directly to a USB 2.0 port? (no hubs, adapters, USB 3.0 ports)

    Have you tried removing all of your other USB devices to test?

    What buffer size settings are you running in the Studio One audio setup?

    Let me know any details you have and we'll get to the bottom of it.

  • Hi,

    I can use either Garage band or Cubase light.
    I am connected into the usb 3 port of my Macbook pro Retina which doesn't have usb 2 post don't think.
    I have removed all other usb devices. The mac mouse is bluetooth.
    The buffer size; 64 samples-32bit single. 44.1Khz.
    Input latency 2.9-output 2.97

    I look forward to hearing from you.

    • Hi Steve,

      The M-Track Quad does not officially support USB 3.0 ports. That may affect the efficiency of the audio/driver communication. Assuming the popping/clicking you're hearing is due to software/driver communication; some have noted improvements when using a USB 2.0 hub into a 3.0 port.

      Also, I'm pretty sure 64 samples is the lowest option in GarageBand and maybe also Cubase. I would recommend trying higher buffer sizes to avoid audio artifacts. They can happen regardless of the computer's processing power when you're running that low, so it's worth a try.
    • Hi,

      The USB2 hub into the Mac's USB3 port worked.
      Thanks very much.
