Well, if we all had Kawais and were living in the UK, we'd clearly be told this is a non-issue. Piano keys are supposed to have non-uniform behavior, at least in the UK.

Do you, N1X owners, use caster cups and which model? I think about it to mitigate noise for my downstair neighbor.
How many cups are necessary, 4 or 5 (the fifth for the kind of support under the pedals which is touching floor and was present on the N1)?

Conventional castor cups wouldn't fit as the rear support is almost like a continuous bar.

Not sure how they would reduce noise either but if you needed to you could put the whole piano on a rug or mat.

Almost like you said! Need some testimony to be sure.
A mat is planned. Wanted to add cups to double the chance to not disturb my neighbour

Here’s what I got: Eison Piano Caster Cups for Upright Piano Wooden Piano Caster Piano Leg Floor Protectors with Non-Slip & Anti-Noise Foam Hardwood Floor Protectors, Set of 4, Black https://www.amazon.com/dp/B07FTFHGGL/ref=cm_sw_r_cp_api_i_BowbDb5RHQSKB

They are sorbathane and have completely dampened the keyboard noise through the floor. Our tv room is right under the piano and the family used to complain about the noise when I played and these eliminated all complaints. Also percy64 is incorrect, though it may look like a continuous bar, there are actually short feet that come out from below the bar that fit the cups just fine. The front legs are a pretty close fit for these cups but are basically perfect. However if you want a little play another 1/2” diameter might be good.

Thanks Percy, that is exactly what I needed to know and hoped to read.
A fifth cup is not necessary?
In the link, is it the right size, I mean exactly the same as yours?

Yes the link is exactly what I got direct from my order history. And yes, 4 is what you need, there are just 4 feet. I should note that you will need “something” else to put under the foot pedal support. With the caster cups the screw will no longer reach the floor. I used a piece of 1x4 I had in my garage. You could probably use a book or whatnot.

Ugh, new problem today. E4 won’t play if you hit it softly. It feels like something in the action is “stuck” much like when you try to repeat a note without it resetting correctly. Another warranty call sigh. I feel bad for the tech, it’s a long trip

Sounds like the jack spring might be loose.

Tried to order the same caster cups as yours but ship to France is not possible. Found these

Looks like yours but the kind of felt under look thiner. I should get'em on wednesday or thursday and the piano will arrived on saturday.



Feel bad FOR YOU! Hope the fix will be easy and quick.

Well - I stand corrected but I am amazed they fit. They must have very shallow cups - there doesn't seem to be more than 3mm although I guess they would work with the leg itself resting on the rim of the cup if necessary

You are forgiven, percy64; for only the brave stand........corrected!

Hi, please allow me to ask a quick question about this, as I can't fathom reading all pages of this thread. As far as the common consensus goes, does this piano have some kind of issue that is prevalent across the user base, like the "loud notes" issue with the NU1X? I remember seeing a YouTube video where someone had chords lock up the action or something, but I can't remember if it was with this model. I think when it comes to hybrid digitals, this would pretty much be the only one that I would consider, so I am curious. Thanks.

There have been no such issues. Unless you consider the N1X being a dust magnet since everyone seems to have that issue.

God Bless,
David

The loud note issues of the NU1 and NU1X has been fixed.

Hello, everyone—I’ve taken delivery of my new N1X, and had a few questions I’d like to ask the group. Before I do, I will say that overall I am extremely impressed. The feel of the keyboard is my single favorite aspect (and why I purchased it), and though the sound is extremely impressive to me overall, I do have a complaint—I’m experiencing what I think is a distortion through its internal speakers. I have a couple of other issues I’d like to ask the group about, too.

Here are the three issues I’ve discovered, starting with the distorted sound:

1) I believe someone else also complained of hearing what to them sounded like a slight audible distortion when playing through the built-in speakers, so maybe I’m not alone in this. To hear it, I don’t have to have the volume turned up all the way to notice it. When I first heard it, I thought maybe the music stand was loose or I had inadvertently left something on the top of the piano that was “buzzing” at certain frequencies, but neither was true. This distorted sound does *not* occur when using headphones (though I guess that is a different sample?). My heart sank when I first noticed it, and thought maybe something was wrong with one (or more) of the internal speaker drivers, but then I discovered this odd behavior: The Bosendorfer sample exhibits it less, and the one VST I own does not exhibit it at all! So what could be the culprit, here?

2) The fallboard cannot be raised all the way upright (where it might touch the little rubber bumpers) without it physically contacting the backside of the black keys. If I don’t pull the fallboard slightly back away from the piano, the black keys actually rub on the fallboard, and you can feel that resistance when playing. I’ve enclosed a picture where you can see this, and have noted the constriction of the red felt by the black keys when the when I try to “seat” the fallboard all the way up. It’s hard for me to imagine the point of rotation could be adjusted, but I am hoping a technician could address this.

3) Compared to my acoustic piano (a Yamaha U1 upright), the pedals seem a bit noisy at the pedal itself. I notice this especially when a pedal is depressed a little off-axis and it moves sideways against the side of the slot it resides in—it then makes a clicking or clunking noise against the pedal box. Both the amount of the sideways play in the pedal and the sound it makes is disconcerting. Has anyone else noticed this, and do you think this could play in the pedal’s movement could be adjusted? (By the way, the adjustable support foot is firmly agains the floor.)

Thanks for any input, and I really enjoy this thread!

Not sure about 1 since I mostly play through headphones. As to 2, it must be something wrong with your piano. Here’s mine:


There are at least 2mm from the back of the black keys to the fallboard when vertical and touching the rubber stoppers.

Regarding 3, I’ve noticed a clicking noise on damper pedal up due to the rubber thing that emulates grand piano damper resistance. It’s a bit annoying. Not sure if you’re talking about the same noise though.

Here’s the slightly louder damper up click on mine:

The fallboard issue sounds like a milder version on mine where the pins had to be adjusted because it wasn’t sitting correctly (though mine actually came off completely).

On a separate topic, my key that wasn’t working right “healed itself” which I’m actually not super happy about. I don’t like things that mysteriously don’t work correctly and then just as mysteriously work fine. It doesn’t breed trust.

CyberGene and Chrispy--

First, CyberGene, the noise you posted in your video is *exactly* what I'm referring to! Thank you, and I guess this is normal and something one has to live with if they find it annoying. Also, I greatly appreciate the image you posted of the space between the fallboard and the back of the black keys--yours certainly looks like that the way it should be.

Second, Chrispy--thank you very much for your post that implies the pins that hold the fallboard can be adjusted--that's hopeful! It sounds like your issue was even more severe than mine, so I'm hoping my issue can be fixed by a technician.

Thank you both again for helping me--what a great community. I have a technician coming tomorrow, and I'm hoping everything can be fixed during that visit. I will report back!
