In Grand pianos there is a mechanism that allows to repeat a note without releasing the key full way.
When this mechanism kicks in, it has a "klick" effect.
This "klick" effect was initially unwanted, it was a bug.
But nowadays it is seen by some as a wanted effect and there are teachers that teach to play near to this klick point when playing pianissimo.
Indeed i think, this effect gives enhanced taktile feedback and can be helpful, but I cant tell from own experience.
Some keyboards imitate the click effect only but not the damper effect, like Kawai RM3, or Roland PHAII.
Other imitate the damper effect, like Yamaha GH3 and Casio triple sensor, but dont imitate the click.
Currently so far I know, Roland PHAIII is the only digital keyboard that imitates both.
(Thats how I understand it, others are welcome to correct me, because I am a self-teached layman)
