Buzzing Sound on Start UP Virus TI Snow (Ground Problem)

  • I've moved my Studio. After reconnecting my gear my Virus Ti Snow makes a Buzzing sound when i put the AU on a Channel in Ableton 9.1
    After checking for updates and disconnecting everything from my iMac nothing changed.
    I've connected the Virus with a longer chord to another circuit outside my room and the buzzing is gone.
    What can I do? The workaround with the other socket ist just a compromise solution for a short time.


    Do I need to isolate the power cable or can I use a usb isolator?
