Diki,
Nobody ever had complains on the keyboard-keybed quality of this machine. Most of us would accept a machine sounding almost perfect, a little tweaking to adjust to personal taste is normal.
Some people say in this case it just takes too much time to make it sound acceptable.

I owned Technics, Solton, Ketron and now Tyros..... none of them required any tweaking in sounds or styles for my taste.
(OOTB) Those manufacturers just know how instruments should sound in specific styles/environments.
E.g. What I strongly dislike is the 'distance-miking' effect in the G70, what makes it sound like in a bathroom....
