I've had soviet baby-grand in my apartment for about 6 or 7 months. I tried to analyze my personal experience. In contrast, it is impossible to reproduce the same exact sound on any acoustic instrument, where each new sound is the unique result of interacting "analogue" processes". Within these 20 steps the user will involuntarily reach the same MIDI value many times and consequently produce the same exact sound as before. For example, playing in mezzo forte with medium strike will activate ± 10 MIDI steps. With our MK22 to "fill" (or to activate) all the MIDI steps from 1 to 127 takes on an average one minute. Even though they come in various combinations, the acoustic colours of the individual notes repeat themselves.

The audible steps are limited to 127, so eventually the musician will catch the same step involuntarily. Also it is impossible to consciously distinguish one step out of the 127. Yes, this might be true: Not even 127 steps can be deliberately played individually. " Any kind of digital stepping is at some point a limitation, dulls the senses faster and quickly leads to boredom.

I watched some videos with russian piano tuners and read a couple of articles on the subject "acoustic and digital piano sound", and these guys say the same Lachnit website says.
