I have a Casio PX100. I'm otherwise happy with it but the one thing that bothers me a lot is the noisy keys. It's so loud that you can hear it even if you are playing with medium volume. It just shouldn't be. I have researched on this a little and it seems that quite some brands of DP have various degree of this problem. I have compared my PX100 to an acoustic piano, and in comparison, the acoustic one had much quieter keys.

I'm thinking about upgrading to a better DP now, I wonder if anyone has one that doesn't have this noise (or at least not very bad), and I'd really like to know what brand it is.

The noise I'm talking about is produced when the keys are released and the weight drops to it's resting position, in the process it hits the back of the case and makes this very loud noise.

As a generalisation Casio seems to be worse than the other brands, perhaps exacerbated by the plastic casing. Roland recently made efforts in their latest models to reduce key noise. You almost never hear complaints about Yamaha or Kawai. All actions make some noise, so check them out yourself in person.

Also someone has started a 'reducing key noise' thread, check it out.

I THINK WE ALL HAVE KEY NOISE WHICH IS ACCEPTED as part of the playing process. I play quietish (small room) and don`t really notice.

What I did notice however, was that even when I recorded the sound internally (on wav.) there was key noise in the recording which was designed into it. Sounds right to me.

Enjoy your key noise! It ain`t gonna go away . . .

My Casio px-150 is noisy but it's a decent keyboard to play and to practice on productively. The wooden Kawai's are very quiet, quiet on the down and almost silent on the up (the casio is as noisy up as down).

In my experience, yamaha, roland, and kawai are all pretty good about having an acceptable (normal) amount of key noise. My old Casio was pretty thumpy, and my Nord is AWFUL about keybed noise (I assume that other Fatar based keyboards are often similarly noisy). It annoys me because it seems like a lot of that noise could be damped out with 30 cents worth of felt and maybe just a bit of rubber dam to isolate the keybed mechanism from the chassis of the instrument. I've been tempted to try to open up my nord and see if I can do something to reduce the noise, but I'm too scared to. Normally I'm not shy about taking things apart to tinker with them, but it's so expensive I would cry if I messed something up. smile

I have opened up my PX100 to examine the source of noise smile , and that's why I knew it in my original post.

There is felt strip on the PX100, but there's still the noise I mentioned. I think it may be improved if the case is make of more sturdy material or if the felt strip is replaced with new one.

My PX100 is noisy up and down both, but the noise of key releasing is much louder than when it's pressed down. The key press noise is acceptable for me, it's the release one that bothers me. If the two noises are about same for you, chances are yours is quieter than mine.

My casio ap-450 produces much noise releasing the keys, it was something I didn't notice in the beginning, but it is becoming increasingly annoying to a level that I play now mostly with a headphone. I strongly advice new buyers to check this.

Peterws has it right. I suggest (easier said than done) that you overcome your reluctance/fright/terror and turn up the volume till you achieve acoustic piano verisimilitude. On good digitals the key sound is no louder than on acoustics played at the same volume level.

I have the same problem, didn't notice this when I bought it, but now it is increasingly annoying me when playing in low volume.the keys bounce back making a 'klung' sound. Piano has been bought 2 years ago, a casio celviano ap450. This is something that next time will be checked and I strongly advice all buyers of a digital piano to check this.

The Casios have come a long way regarding their action, so more than likely it's just how it is with that particular model (though I don't know if they reduced the action sound with the better action). Chances are you will have to either turn up the volume more, or practice with headphones. Might be worth checking out some other actions of different DPs in your local store to compare the noise level. Your may be within reasonable levels and you're just practicing at too low a volume.

I can just confirm that my Casio PX-150 (same as all recent Privias) has super noisy action though I got used to it and don't notice lately.

Just throwing out a notion...
it's not like acoustic piano actions are silent.
But I suppose the plastic parts might be a little more clicky than wood and metal screws.
But then again, I've had plenty of young ladies take lessons that refuse to sacrifice their nails for music - talk about clicky. wink

I agree. It is a drawback.

I just received a PX160, and it is much quieter than the PX-350 that I owned. I had the PX-350 in the garage for a year while I attended to a sick family member. When I brought it into the house, I noticed that it was so noisy. I don't know if it was dust or the 2-3 hours a day of practice that I put into it for 1 1/2 years previously.

With the PX160, the key noise is not bothersome. I'm not suggesting that the key action is any different from the previous model - even though it is conceivable that Casio might have used thicker felt or something to make it a tiny bit quieter.

Even the N2 has what I think is unacceptably loud key-bedding noise. Even with open-back headphones on medium level this can be a problem at times. My wife watching TV in the next room has her own opinions on this!

The thing is, real actions make a fair knock - so if you go putting in super soft keybed felts just because it's a digital piano, you have to accept that the action will not feel like an acoustic anymore. Acoustic pianos are not mushy in the way they bottom out. The AG series is predicated on being a real acoustic action, so it's my guess that they don't find a super soft keybed to be authentic enough to most real pianists.

Of course, there's no reason an enterprising owner couldn't have a technician replace the keybed felts to a softer type, but any results would have a finite lifespan. Felt compresses over time with use - so if the felts were soft, they would eventually reduce in thickness and increase in hardness - which would result in both change in touch and a loss of regulation (excessive keydip).

I'd be willing to give up some realism for less mechanical noise. I was at the piano shop the other day and noticed the Kawai kdp90 seemed to have the least amount of physical key noise against high end Roland and Yamaha Pianos. Of course this is their entry level digital with lower quality sounds. There were no higher end Kawai pianos at this shop.

It`s simple. Cheaper digital has more noise because of cheaper plastic keys. Previosly I have Yamaha p95, and Casio cdp 120. Yamaha was terrible, there is no way to play at night normaly because of clunky action. Casio cdp 120 was little better. From cdp 120 and up, Casio improve their action, but still has lot of noise. No matter that, its still better then GHS keys on Yamaha. Unfortunately, every key action has a noise, but Kawai is the best. So, if you want maximum silence as possible, grab Kawai, but of course, you must invest more money. I have no complaints for noise on my Kawai VPC1. It has normal noise but it`s very silent. Perfect.

Hi friend, I agree with you... Kawai is the best in silent key actions and then follow the latest roland PHA4 and PHA50, then could be Yamaha GH? and NW, then Roland Ivory S and G and in last place Casio and Yamaha GHS actions.
This would be a list in order, starting from the quietest to loudest key actions:
1. Kawai GFII/GF/RM3II
2. Kawai RHII/RH3
3. Kawai AHA-IV
4. Roland PHA50/PHA4
5. Yamaha NW/GH3/GH
6. Roland Ivory S/G
7. Casio Tri sensor SHA II
8. Yamaha GHS
9. Casio SHA in CDP and oldest Privias.
Please bring us your opinion... Thanks.
