Looks like an NS4 to me. 88 keys version?

The volume of the sound is difficult to judge from the video. But I don't hear a noise that would bother me. There is a certain sound while pressing the keys, and there is a soft release sound, too. Sounds well dampened, probably well lubricated as well. You might want to check if keys can hit neighboured keys - they shouldn't.

thanks for the reply, yes it is an 88 key ns4 bought yesterday I wanted to know these noises that the keys make and is everything normal also does your ns4 make these noises while pressing the keys with the instrument turned off?
Thank you

I do not own a NS4-88 nor a predecessor (with a Fatar TP/40 key action). I just compared to my NS3 Compact (Fatar TP/8O) and to my Kawai VPC1. Your sound seems closer to the latter - which is a high quality piano key action, too.

That's why I say that there is nothing obviously wrong to me. Would be great if someone with a NS4 would confirm.

The Fatar TP40 mounted in a metal chassis and without additional dumping felts (like in the Nord Stage but also other keyboards using the same keybed) can be that "noisy".

Relatively speaking, being the NS4 a stage keyboard is something which is not really an issue in that context and also at home I never found it as an issue: have you ever tried to hear how noisy a real piano keyboard is by itself, for example when playing with a felt (or a Silent model)? Btw some virtual piano even reproduce that key noise (Pianoteq does for example). The difference is that in an acoustic piano that noise is covered by the sound, while on an electronic keyboard you have the volume or you can use headphones...

so is everything normal? Does yours also make different noises on some keys?
I wanted to be sure it wasn't a manufacturing defect
Thank you

hi the problem is not the noise of the hammers touching the felt base here in addition to what all keyboards normally do and softly it feels as if the key is touching the iron structure at the top of the front panel i.e. where the keys begin you can hear it a plastic noise if you press two keys at the same time for example mi and fa and you release them even gently you will notice that the keys touch on the top part of the key I attach a photo to help you understand
Thank you

That's exactly the "missing felt" I meant which in other keyboards is instead present, not the one at the bottom.
Anyway normally the keys shouldn't bounce so much to touch that part of the chassis.

I tried some piano5 and some stage4 all the same thing however on a five thousand euro keyboard they could have opted for a mechanism made a little better perhaps with wooden keys like cp88 only in the 88 key version

grazie per le risposte

Unfortunately Nord unlike Yamaha does not manufacture keybeds, they have to buy them from general (non-competitor) 3rd parties like Fatar (the Kawai one for Nord Grand being the only exception so far and it has problems too)

So the only 88 HA wooden keys Nord may get are the Fatar TP40W or TP400W, which would increase weight over 22 Kilos (see Numa X Piano GT specs ): call it a compromise.
