And additionally I came across a feature of the Virus, where Access Music has exactly addressed, what I am complaining:
In order to not have 'jumps' when turning certain knobs, it is possible to choose 'Snap' (instead of the default 'Jump') for Knob Behavior in the Config! That means you can turn a knob without any effect, until it reaches the default value. It will show a small arrow to remind you first going to the default.
Not bad. They already considered it!
