Nice thread. I'm pretty much a Yamaha guy when it comes to hybrids but I have to say the sound from the Kawai is really impressive. It would make me think twice and I would love to have a go and see how I feel about the action etc.

My machine is the 1.0.1 version. I don't now how to get the 1.0.2 version and note that a couple of people that have this version do not mention buzzing. I don't know if 1.02 makes any kind of changes that affects this (or if it really can) but as I recall Kawai doesn't (yet?) have a used downloadable upgrade to v1.0.2, but if you're on an older version you can give Kawai a call and they will make sure you get set up correctly.

I agree that it's a shame the NV10 has this buzzing in the first place, and also that you do learn to accept it. My machine is the 1.0.1 version. I don't now how to get the 1.0.2 version and note that a couple of people that have this version do not mention buzzing. I have reduced the buzzing to almost zero (like from 100% down to 1-2%) by creating a user tone setting and reduced the High frequency setting from 5 to 2. I could reduce more but felt 2 was fine. This keeps the singing tone more than going for the mellow 2 setting. Also agree some piano styles such as Jazz are better. But the user tone setting made a huge difference without really affecting the sound at all, compared to using the mellow settings. UKchap, When did you get your NV10? You must have one of the first made. Was it released in the UK first? I would think the update for the CA98 would work. It has been out since last December. (Confirm with Kawai Support of course.)

Out of curiosity, a question to the NV10 owners that also owned or used a Kawai with GF or GF-II action: is the mechanical noise of the NV-10's action louder or "noisier" than the GF?

As for the others, is it really true that the 1.0.2 version does not have this issue anymore? What I wrote before applies to my piano, which has 1.0.2. Out of curiosity, a question to the NV10 owners that also owned or used a Kawai with GF or GF-II action: is the mechanical noise of the NV-10's action louder or "noisier" than the GF? I had the CA97 with GFII. The Novus action is very noticeably louder than the GFII. Not the keys themselves, but the noises from "inside", i.e. the whole wippen/hammer/back check mechanism.

I had a quick look back at the settings last night. I got my figures a bit wrong. Firstly, see page 126 of the user manual. I adjusted the 'High' setting from 0 to -4 dB. -3 dB almost did it but I found -4 a smidge better. I'm not quite sure of the frequency setting side of things - I didn't touch that. But may do in the future. Changing the 'High' setting made a considerable difference to the buzzing (massive in fact). I agree at first it seems like the speakers are broken. Now I think they are just not filtering enough of the high pitch tones correctly. I appreciate that much of the 'singing' of a piano sound is from those high tones, but Kawai need to do some tweaking and lose the bits that normal ears just don't pick up too much. Funny story about how I worked this out though!!! I'd had the piano for a few weeks and just put up with it basically. Love it so much so was ok about it. Then one night my wife called me on the car phone, and she was going on and on, and making the speakers buzz, which for some reason only her voice does this. I was thinking her voice must be a higher frequency. Then suddenly thought that may be the issue on my piano!!! - Too much High frequency!'. Kawai, do you have a User Tone Control for BMW speakers/wifey voices?

Why don't you try to identify the buzzing sound with some sweep generators like: http://www.szynalski.com/tone-generator/Put speaker volume rather low so you don't destroy the system. Maybe a speaker cover is rattling or a screw needs to be tightened or maybe a rubber gasket can resolve the sound. . .

The buzzing isn't lose speaker cover or speakers. It's a sound frequency thing I believe. An electrical sound rather than a mechanical fail sound.

Thanks for the clarifications! I'll go try that out at my local dealer, and will report back. (Btw, I assume it's possible to just save those settings to the pianist mode, right? So you don't have to edit them every time you play...) Also nice it goes with a memorable story.

Yes, it saves those settings globally, I've found. So you don't have to change them for every favourite. Ps, only my car makes my wife sound high pitched! Not sure she was overly impressed with her assistance in improving the sound pf my new toy!! lol I was over the moon!

I've had my NV10 for nearly six weeks now. I've not played my acoustic baby grand once in that time. Yet again last night, the touch, feel and expression possible on the NV10 had me almost in tears whilst playing. Love it love it love it.

Yes, this is correct. Unfortunately, software updates for the NV10 cannot be made publicly available in the usual way for reasons related to Bluetooth licensing. If NV10 customers find that their instrument is still running the v1.0.1 software, it is recommended that they contact their Kawai distributor to receive information on updating the instrument. I would think the [v1.0.2] update for the CA98 would work. It has been out since last December. (Confirm with Kawai Support of course.) The CA98 and NV10 share very similar hardware and software, however the software updates for the two instruments cannot and should not be interchanged. To clarify, the NV10 is not compatible with the CA98/CA78 software update. Kind regards, James x

I feel the opposite right now. I've been away from home for the last few days and I'm just aching to come back to the NV10. It's such a joy to play.

It's the weekend, and I felt like tinkering again, so when my wife notice a smudge of dirt at the side of the white keytop material (the side edge of the front piece) of one key, this of course had to be cleaned immediately, giving me the perfect excuse to take out the fallboard again and tinker with my piano. Because you see, to be able to clean that edge (which by itself took only a second or two), I had to lift the key up more than is normally possible. And to do that, I simply had to take out the fallboard and also remove that wooden strip that stops the keys from moving upwards, didn't I? I mean, what else could I do??? Hmmm, and with that strip out of the way, why not finally get a perfect measurement of that "oh so important" pivot length? So here it is, exact to the millimeter (I'll leave that pesky conversion to inches to you folks): White keys pivot length: 25.9cm from white key front lip to center of balance pin. Black keys pivot length: 22.5cm from black key front edge to center of balance pin. And while I was in there, I took a picture of this here too, as many people are always interested in where something is manufactured:

Nice job, JoBert. Ya gotta keep it clean. White keys, 10.2 inches. Black keys 8.86 inches. Do you think they are the same length as a GL30 or a GX1? I read somewhere it is the same (modified) action as the GX1. However the GX series have Neotex keys. So I assume it is closer to the GL series action with Acrylic and Phenol keys. (The GL30 and a GX1 are both 166cm.)

Thank you JoBert for sharing these pictures. That is a really impressive pivot length.

If NV10 customers find that their instrument is still running the v1.0.1 software, it is recommended that they contact their Kawai distributor to receive information on updating the instrument.
So, what is the way to update the software on NV10? Does it require a tech visit at home? That could get expensive down the line (I am assuming there will be more software updates in the future - correct me if that is not planned). Osho

The software can be updated from a USB stick, like with other models. You just have to contact Kawai to get it in the first place. There's no public download link for it.
