@RuminativeRat: Congratulations. Great Choice. I have my NV5 for nearly two years now and still love it. It means something because i usually haven't kept a digital more than a year before something made me upset. laugh

Thanks Ruminative Rat (or David, as your youtube recording shows),

Very nice summary of the instrument, which does not seem to have any problems playing at a speed you play, which many people can only dream of (like myself, at least for now).

Thanks also for introducing us (well myself at least) to Forest of Piano and N. Kapustin. I wasn't aware of either and I am intrigued by both.

Thanks everyone for the warm welcome.

Yeah, when I signed up I wasn't sure whether to use my real name or one of my more distinctive pseudonyms. I feel more anonymous with my real just because of how common it is. But personally, I try not to be so anonymous to the point where I say things that I'm not comfortable to back up in person. I also go by caiuschen elsewhere online.

I really like Nikolai Kapustin. I'm also working on his Pastoral etude and a duet for cello and piano with a friend, Nearly Waltz.

More on topic: there was one thing that I forgot to mention, which is that the music desk placement on the NV5 may not be for everyone. I do find that my fingers hit it once in a while. Something I can learn to avoid, but something to be aware of. I'm not really sure where else it could be and still keep the piano as compact, though.

This is something that bothers me too with all upright cabinets. I find it sometimes more practical with a classic DP cabinet even if it's not that good looking, both for the issue you describe but also for ergonomics. I feel it's kind of a bummer that Yamaha and Kawai only offer their high end DP:s as upright cabinet except for the grand piano hybrids. Kawai used to have the CA9X but thats's designed as an upright nowadays too.

I also did not like how it looked as much, so the net effect was just that I did not enjoy it as much as the NV5, which was a pleasant surprise for my wallet.
  • A common consideration that comes up in regards to the NV5 is that due to it having a real upright piano action, it includes a notable disadvantage of an upright: the key needs to reset at least some before being played again, or else it will not sound. This limits how fast a note can repeat and may limit other techniques that depend on the key not being fully reset (less fast repeated pianissimo maybe? I can't say that I've ever intentionally depended on this other than for very fast repetition). On this point:
    • I would indeed sometimes hit dead notes on the pieces I played, but this was due to poor technique on my part and not because the piece ran into the limitations of an upright action.
    • Compared to a K300 Aures in the store, very fast repeated notes would actually "blur" unnaturally on the NV5 in a way that I don't think a real piano would ever do while still sounding mostly distinct on the K300. But this was at a speed beyond any piece I've ever had to play. It would probably make playing something like the Scarlatti Sonata in D minor K. 141 harder, though, if it's even possible.
    • The key does not have to completely reset on either the NV5 nor K300 to sound, but it actually did have to reset further on the NV5 than the K300 to sound. So, the K300 is actually somewhat better than the NV5 in this regard.
    • I decided that, while this limitation was unfortunate, I'd be okay avoiding pieces that can't be played on an upright. At some point you just need a real grand piano to play certain pieces; I've seen avant garde stuff where the pianist reaches into the piano to pluck the strings. On the positive side, I tend to like playing on random pianos and this would allow me to practice avoiding technique that cause dead notes on real uprights.

I'm especially interested on the NV10(S) and upright repetition "shortcomings" topic: I really like the sound and sleek look of the NV5 ... yet the opportunity to play on a grand action is still appealing. I think your recording of Kapustin's Etude - absolutely brilliant - shows that repetition speed isn't a real concern to have.
I wish you a lot of fun with your NV5 😃!

Thank you very much, Marchelune! I wouldn't quite phrase the the lack of limitation quite that strongly, though. There are certainly interpretations of that piece that go much faster that may not be possible on the NV5, and I think my testing shows that even the K300 seems to be capable of faster repetition than the NV5 even though it uses the same action. But I did want to show that it's not an issue at least at that tempo, and that I suspect the limiting factor for me and many others is likely to be the player and not the piano, and to consider whether one actually has any pieces one wants to play that needs repeated notes faster than that.

Now I'm really curious how fast I can play the first two lines of Scarlatti Sonata in D minor K. 141, which I thought may not be doable with the NV5. I just practiced the right hand for 15 minutes and can play it at 90% speed of the Youtube recording, so I might have been incorrect about it not being practical to achieve on the NV5.

The other example I've heard cited as being difficult to do on an upright is Ravel's Ondine. I'm not sure which section people are referring to as the sticking point, but I'm going to guess it's right at the beginning. While the repetition is not necessarily that fast, it's supposed to be pianississimo, and that seems like it'd be easier to do if you didn't have to have the key rise back as much. But at my skill level, I'd be happy if I could pull it off a little louder than intended.

Hello all Kawai NV5 owners ! I have a simple question ! I have Kawai CA99 and the only thing I do not like about it is pedals.....very,very heavy, all pedals work very hard /I mean they are very hard to press ! I am ready to switch to NV5 if the demper pedal is softer ! Enyone has some own experience, comparison of the stiffnes of demper pedal i those two modells ?

Hello,

@Maciek1965, I do not own a CA99 nor NV5(S), but would like to offer you this thought:

If the pedal stiffness for you is really the only drawback of your CA99, it is a pity and an unnecessary hassle to trade it for something else.

The simple solution is to install a lighter spring in the damper pedal. That should be reasonably straightforward and has been done already by several people on this forum, if I am correct.

I hope one of these people can chime in on this for you, and it would be worthwhile to search the forum yourself to find the examples.

Cheers and happy simple solutions,

HZ

PS Please be aware of potential consequences for the warranty on your instrument that DIY modifications may have.

Thanks a lot HZ !
Of course it sound reasonable to change a spring to lighter but I was afraid that it is to complicated but I will try to find out how the others did ? A lot of the owners had the same feeling /hard pedals/ and the company does not do enything about it ! Strange!

I can't comment on the stiffness of the CA99, however I do own an NV5. Initially I thought the pedal was stiff and planned to swap the spring for a lighter one. However, with time I adapted to the pedal and never actually changed the spring.

It's not a big issue at all. However I still think a (slighly) lighter spring would be better because I can't feel the point at which the pedal actually starts supporting the damper weight. I can feel it in the keys, and I can hear when the pedal sensor triggers a change in sound. But the optimum would be to also feel it in the foot, and calibrate the pedal sensor to the same position (which is possible in the touchscreen menu).

Hi Pppianomarc ! Do You know how to do that ? To change a spring to the lighter one ? Is it complicated ? I am ready to do that because the stiffnes for me is unacceptable ! Best regards , Maciej

Dear all,

I am back after more than one year of happy piano learning with my wife's NV5. Now we have a problem: after about one year of regular usage (1-2 hours per day), some keys have developed a very annoying rubbing noise. It's clearly velocity dependent and it sounds as if some extra friction would occur when these keys are pressed. There is no noise on key rebound.

Yesterday a technician came to check the action. The noise appears to be caused by tiny plastic pistons or cylinders. These are equipped with a spring and get engaged when a key is pressed down. I could clearly see the movement by looking at an angle through the action. He took a video and will get in touch with Kawai to see what can be done.

My question is: has any NV5 owner experienced something like this? Is this a known problem that has been sorted out in the new NV5S? My wife loves the NV5 but she finds the noise very annoying. I am an absolute beginner and do not care so much but, even with my bad hearing, I can hear the noise very clearly.

Thanks,
nbpf
