Some Sounds only hearable on right stereo channel

  • Hi there !


    On my new Virus TI2 Desktop, some Sounds are only hearable on the right Stereo Channel. Is this normal or are there issues with my machine ?
    Not many Sounds are affected, only a few : for Example Factory ROM-U 76 "VOC osc 1"
    When I enable a Little Reverb or Delay, the Sound gets hearable on both channels. I had this Effect before an after an OS Update (5.03 --> 5.17)


    Perhaps someone can tell if one gets the same Behavoiur.

    Thanks in Advance !

  • Which outputs are you using?

    - Headphones

    - Line outs (which pairs)

    - USB digital

  • I got this behaviour with any audio output: analog outs (I only tried pair I) , headphones as well as USB audio.

    Doing some test I believe the affected sounds/patches are all vocoder related ? No input signal is attached. Filters seem to be disabled. A little

    reverb or changing the first oscillator to any other type will make both channels hearable, but Signal starts fading and stays on the right again after about 15 secs (???)

    Enabling delay has no effect, but changing chorus to rotary will make the signal audible on both channels permanently.


    Is this perhaps normal for vocoder patches ? I was reading a post somewhere that vocoder patches split stereo channels for orginal/processed Input signals.

    *Edit*


    Ok, i tested with Factory ROM-U 76 "VOC osc 1":

    If there is an Input signal this patch sounds quite normal "vocodish" on both stereo channels with normal volume and no recognizable difference between channels.
    With inputs plugged but no signal (played over MIDI (USB as well as MIDI IN)) I got a significant louder signal only on one Stereo channel.
    Im not sure about this… is that normal and only sounds weird missing any input Signal or does my machine behave wrong ?

    I only tried with Input via USB (using the Virus Control Plugin), but it generally behaves the same.

    Sounds normal and behaves as Vocoder when input signal is available (side chain input for VC plugin enabled) and has about 20 dB louder output on right channel only if not input signal is available (side chain input for VC plugin disabled).


    Behaviour, seems hard to understand to be normal.

  • Ok, thanks for testing !


    Seems to be either a bug or a feature then... ? Changing Input levels (settings) or noodling with some Parameters stops the behaviour, unfortunately only for a few seconds.

    Perhaps some sounds are misconfigured ? I don´t use the vocoder anyway so I can live with that.


    So again : really thanks for testing, I am very happy not to have a faulty device !
