Yes, among some other reasons as i.e. technicsplayer mention here.
I can't remember last time I saw a advert for Technics keyboards here
in my country.
Also the swinging trends, remeber 20 - 25 years ago?
Big 2 manual organs was the big thing, so the arranger keyboards came
and made a "revolution".
Now I can see it's a kind of back to basic. The young ones buy pianos,
the old fashion acoustic type.
It's good, because if you can handle and play a ordinary piano, then you
really have what needed........
Well, my personal meaning, of course
