Noise on Stereo Outs when USB connected

  • Hi, I have a significant noise and cracle (no 50 HZ hum!) on my outputs if the Virus TI, when the USB Connection plugged into the computer. it dissapears, when I unplug the USB Cable. Different cables and USB-busses doesn´t change anything... Any help? Thanks!

  • Hi All, It sounds like I have the same issue here.
    Mac computer with Logic 9 and virus Ti sw version
    When i start up the VST virus plugin I have a constant noise.
    Any one can help?

  • Hi Flabberbob thanks for the replay.
    No I am not using it as Soundcard, but even if I do it gives the same problem.
    If I just remove the Virus plugin in Logic the Noise disappear so I can't understand if it's a sync problem or what.
    I have updated everything and also done a factory reset with no success.
    I can't find the INPUT THRU parameter

  • Ok found it thanks. It is set to 0.
    as soon as I start the plug in what I hear is just a constant noise (almost like white noise) and no matter what I do, play, stop or something else and nothing change. if I play some notes I see the meter bar in the VST Virus plug in moving like if it's correctly playing but in the meter bar of Logic channel I can see this constant noise playing (and hear it too).
    I tried changing USB port, removing all other USB devices but nothing.
    Some Logic Settings?
    I am still using Logic 9.1.8 32bit.
