Huh?

You are not saying the keyboard is pressure sensitive, are you? It is not.
The tonewheels are loosely spring coupled to shafts that rotate at different
speeds but which are locked together with gears.

So the wheel itself runs at a constant average speed, but is free to
fluctuate speed slightly. This causes the constant tiny changes in phase
between wheels which keeps them from sounding static and dead.

But it has nothing at all to do with key pressure. You can control the
spread of the key click by the speed you press the key. And you can cause
some of the harmonics to sound by themselves by carefully pressing the key
part way down.
