Valueknobs don't hold value

  • Hi,


    When i play a patch on my Virus TI 2 Desktop (like ROM-O 9 AlfBass RP) and i turn the value knobs below the screen then they work. But as soon as i hit a different note they don't work anymore.
    How do i set them to keep their value whilst playing several different notes?


    Greetings,
