Problems when using FX plugins

  • When I use the standalone version, Bias FX works great, but when I use it as plugin in Mixbus, it keeps freezing. When the tracks are not playing, I can move knobs and change settings, even though they everything is very laggy, like when playing an online game over a bad connection and the graphics/animations are pixelated and sometimes so bad that I cant see on which side of the knob the position marker is.
    When I start playing the tracks, FX freezes completely and I cant do anything at all. The in- and output level meters are frozen the knobs wont turn at all...

    Advise on how to solve this problem is greatly appreciated.
