Having different weights is seen by DP makers as a selling point since it mimics acoustic piano. Then we have different action names which does reflect this gradation (Graded Hammer by Yamaha, Progressive Hammer Action by Roland).

In the same way, we can have key and pedal noises with some VST (don’t know about DP).

[off topic about hybrid actions]

I have seen a video about the repair of an acoustic piano from 1905 with an hybrid action... yes hybrid !

The lower part of the piano has overdampers (see http://www.pianos.fr/en/mecanique-baionnette-391.html) - in France we call the action bayonet action - and the higher part has a normal (modern) action.

I agree. When I tried the gp500 the Debussy scene was my favourite. The extra resonance really made a difference. I also think it's the most realistic resonance modelling of any of the DPs I tried.

When I restarted playing as an adult after
twenty yrs. away from the piano, the first
piano I bought was an expensive acoustic
upright. This was in the early 1980's and it
cost ~$6000, a huge amount for an upright
in those days (a similar model today would
be in the ~$20,000 price range). My
reasoning was that the best piano available
would help my playing, but I soon realized I
was badly mistaken. The expensive piano
didn't help my playing one iota. In total
disgust, I put the piano into storage where
it remains to this day.

I didn't play again until 1989 when I
happened to wander into a piano store,
and I was literally floored by the digital
pianos. Even way back then there were
digitals with fully-weighted keys that played
just like an acoustic piano. I immediately
recognized the potential of digitals. Here
was the answer to all of my problems on
the piano: a lightweight, maintenance-free,
grand piano-like instrument with volume
control. I was so impressed that I bought it
on the spot, a Korg C-800 console for
$1700. Since then I have owned 3 more
digitals: a Casio AP-24 that I bought sight-
unseen online in 2005 for $700; a Korg SP-
250 that I bought sight-unseen online in
2006 for $900; and my current piano, a
Williams Overture that I bought sight-
unseen online in 2009 for $600.

You can see from the above that I have gone
to cheaper and cheaper pianos, even as my
playing has improved: ~$20,000(~$6000)-->
$1700-->$700-->$900-->$600. In fact I like
the Williams, the cheapest of the five, the
best of all. It serves adequately for any
playing, from jazz improvisation to the
biggest concertos.

I think he's now progressed into an advanced level of big-time piano concerto playing which requires no piano at all. He can mentally practice it. BTW, you can laugh it and all, but that's how Glenn Gould practiced - without a piano. How about that, huh?

I was speaking with a professional concert pianist about a year ago about his comeback after an early retirement, and he said that is essentially what he seriously did when he had a first big recording to make after many years, but no access to a piano. I don't know exactly what he did to prepare himself, but in my mind, I am picturing "air piano"! laugh

Jerry Lewis did it rather well in the movie Artists and Models:

Scroll to the 08:10 mark. Both the piano, and the whole movie is out of tune though.

Tested the GP-300 today.

C8: 40 grams
Middle C: 54 grams
A1: 59 grams

Significantly lighter than my Roland FP-80 in the mid-range and treble.

Sound: good (I don't want it loud anyway as we live in a apartment). The 'Chorus' effect was disabled by default, so I left it that way.

Keys: less grip than a dog on lino. It could have been the fact they didn't have air conditioning on and my hands were sweaty from pushing a stroller 1 and 1/2 hours across Singapore in humid hazy heat, but my hands were slipping on the ivories. Conversely the ebonies were actually a lot more grippy (much more grippy than Yamaha CLP-685 ebonies I tested last night).

Main concerns:
Large weight grading across the keys - 19 grams from A1 to C8. Fazioli has 4 grams, Steinway has 3 grams. 19 grams is too much.
Slippery white keys - the Kawai CA78 wins easily here.

I think my decision will come down to the key weightings of the CA78.

I assume that the grams and their values that you find on particular keys of the keyboard do change depending on your setting of the touch of the keyboard.

I don't think so. The touch settings on a DP are purely changing the software, and will not have any influence over the physical weight of the keyboard.

OK, so I measured the CA78 key weightings this evening.

A0: 61 grams
Middle C: 53 grams
C8: 46 grams.

I must also add that every time I play the CA78 I fall even more in love with the key surface texture. I swear Kawai have the best key surface I've ever played on.

However the greatest shock was the price... Retail: USD $4,500, sale: USD $3,800.

So the USD $1,400 Casio GP-300 looks like the winner. Just need to add a subwoofer smile
