Hello everybody, I'm very glad I received yor helpful answers. I read =
all of them carefully, and last evening I did some checkings in order to =
share them with you. I want to give you more antecedents and what I =
found out :

- Damper and hammer lift at the same time.
- I don't have gram weights at home, but my wife has a digital kitchen =
scale. So I can know in a very accurately way the weight o different =
objects. I checked the 'typical' weight to push down a key (50 g), using =
a 56g object (with the sustain pedal depressed) and only a few keys =
traveled down a little (1/3 cm), the others didn't travel at all.
- Before the C1 I had a C108 (Yamaha upright). The action wasn't =
'light', but now I don't remember it was so 'heavy' as the C1. I played =
in the past other Yamaha grands (C7, CFIIIS, GH1) and I don't remember =
they had 'heavy' touch. At my piano school we had a B=F6sendorfer, and =
it was OK for me. Now I have a Yamaha digital piano P200, at home, in =
which I study late at night, it has a very light touch. Maybe it's =
confusing me...
- I find the keyboard action is 'heavy' especially in fast passages, I'm =
now studing Chopin's waltzes # 1 and # 6 (Minute). In other slow pieces =
the effect is not recognizable.
- Keys fall down under their own weight, so I don't think that action =
centers are too tight.

And I have more questions, too :

- Since my piano is only 4 months old, why should I ask a technician for =
:
    - Revise tightness in key bushings and balance rail hole ?
    - Cleaning and polishing keypins and capstans ?
    - Checking centers for excessive friction? Lubricate knuckles ?
- Shoul I expect that a new piano (and not the cheapest one) must have =
all these things working all right ?
- It is reasonable to expect that keyboard action in a grand piano must =
be 'ligther' than an upright piano ? (at similar quality, I mean).
- Would be a good deal to adjust the repetition spring tension ? And if =
I loose repetition speed ?
- What does mean 'after touch' ?
- Are there notorius differences between actions of different grand =
pianos ? Should I expect a Steinway is 'ligther' than a Yamaha ? My arms =
and hands are not strong, and I really feel comfortable with soft =
mechanisms. Is this a sin ?

And a special mention to Robert S. Kuhn, thanks for your advice, I will =
follow it. Surely I will really appreciate your offer. Don't forget to =
tell me when it happens !

Best regards,

Fernando
