For those who complain about Kawai keys "bouncing" - here's a vid of an acoustic piano's keys bouncing. And yep, the owner is complaining, altho techs on the Tuner-Technicians forum are responding that it's normal.

Also keys noise.
At 0,25 you can hear it on this silent AP.
After hearing this I do not look at my DP the same way (concerning key noise), and I find it rather silencious...

What's wrong with a little bounce? I've always found it quite fetching myself ...

There was a key bounce discussion on the NV-10 thread a few years back. I took these videos:

7ft Bosendorfer Renner action:

NV-10 Millennium III action:

Bounce happens.

There is an important nuance. Bounce consists of two things: the inertial motion of the key, and the sound it makes. So, for me the problem is not in the inertial movement of the key itself, but in the sound. And on some digital pianos, that sound really bothers me. I haven't experienced this on acoustic instruments. Don't say me, acoustic grand pianos are simply loud and I didn't hear that bouncing. I play with headphones at a sufficient volume and the bounce sound gets in the way on some models. In addition, even if you gently (quietly) press a key/keys and then abruptly release it/them, some digital pianos make a much more noticeable bounce sound than they do on acoustic instruments. So don't tell me bounce is OK. It depends!

Ok, so of course, the sound and volume of key return noise is a valid issue. Technically, it's not really bounce you're concerned about, it's merely sound damping. You can have an action (acoustic or digital) that has a high degree of bounce, but little or no sound. Similarly, your action could have zero bounce but it can thud or thump or clack or echo loudly. So yes, one of the important aspects of a digital action is how quiet it is (and how quiet it stays after a few months/years of constant play), but that's largely independent of whether the key bounces or not on key return. So in that sense, bounce IS ok (so long as it's quiet) smile

There is bounce and then there is bounce. Just like there are differences in how keyboards feel.

I was interested in the ES8 and liked it a lot but the bouncing was of a distracting magnitude to me. A CN39 nearby in the same store (also RHIII) wasn't bouncing disturbingly. So I think it can be a matter of the damping strips. So the release notes of the recent KDP120 imply.

There's always a bit of bounce, but the Kawai bounce is Obscene and far too long a duration.

OK, since someone voiced the brand, here's my +1.
I liked the way someone once compared it to a springboard for diving.

The springy bounce makes sense because, you know, some keyboard actions actually have springs.

With the inevitable mention of springs, the discussion then unravels...


A man must love a thing very much if he practices it without any hope of fame or money, but even practice it without any hope of doing it well. Such a man must love the toils of the work more than any other man can love the rewards of it.

I sometimes wonder if the excess lightness, fluffiness, and bounciness in newer Kawais is directed at attracting younger millennials asking for ‘more fun’ and less work; you know, akin to a play-date in a bouncy-castle: it can be tons of fun, bouncing around in a plastic, fluffy castle.

So yes, this is yet another example of how millennials are messing everything up! grin

But when they bounce, should the notes not sound again? A little echo could be nice . . . .
It'd sound like you played it twice.
