Pressing a key on any piano is not exactly equivalent to fixed “force” because movement is involved, as well as tactile feedback from the inertia and static weight and what we intuitively try to achieve is a target key acceleration, instead of target force. Thus, on an acoustic piano, when you press the damper pedal, the keys become lighter and easier to accelerate and you can intuitively press them with a lighter force to accelerate them with the desired acceleration (rather than desired terminal velocity, because often you might not even press all the way down, only keep the momentum do the rest).
However, in the world of MIDI controllers where you have no dampers and no varying key weight, you will always press with the same target acceleration and if the underlying samples have different audio volume, that’s a problem. The Novus is a special case and I think no current virtual piano would make up for the fact it has varying key weight. Ideally, there would be a parameter which, when enabled, will produce slightly louder sounds when damper pedal is pressed.
