Plastic sounds on some keys on my digital

[stefo78]

Hello,
I have some disturbing noises with some keys of my digital piano (a Kawai CN23).
Here is the illustration. The little "clics" can be very annoying when playing.
Do you think it is normal ? Is it because my piano is of too low quality ? too old ? to be changed ? Have you the same problem with your digitals ?

What should I do ? The piano isn't anymore under quality guarantee.

Thanks,
Stefo

I have one question, is this a new development or something that has gone unnoticed till  now ?

 The CN23 I believe does have plastic action and key cores with stainless or chromed steel bearing points ( I believe but don't quote me. You should be able to see between the keys and catch glimpses of shiny metal parts in there I think). The action should be quite good but a bit noisy compared with wood. The side movement you are showing is about the limit of what I would want to see. I would say that both are fairly consistent with my MP6 experience, which has decent movement if a bit noisy on return when playing silently. I would say that my MP6 has worn into this state or broken into this state and that I do play it a lot and very heavy handed at times. I do not consider it worn out by any stretch. my grand piano would have had several adjustments made in this same time period. When playing live with a sound system turned on it's virtually unnoticeable. You have to pay considerably more for a Kawai with wooden key cores but at that test well before you buy. I think that my next investment will include that but not for some time ( maybe when the MP 11 goes on sale and since it was just released that's going to be quite a few years down the road and I'm not upgrading my MP6 for an MP10)..

I'm not sure I quite completly understood your question, but I feel that these noises were not present at the beginning. However, I started with it as a newbie, and maybe I was not conscious of these sounds. In addition, like phenomena which appears very progressively and slowly, you don't really notice the problem at a precise moment.

Your reply indicates that you understood my message question. Your points well thought out. I did edit the question slightly because I saw where there could be confusion as I wrote it.

Since my reply this morning I looked up the CN24 action and it appears that it is different in design than my MP action and it appears that is has more plastic in it's construction than on the MP6. I do get some side movement with mine but no clicking noises. The clunking when letting a key go and have it freely return with no finger pressure on the key is there. Again a subtle clunk but not a clicking sound. You can also feel and hear if listening close enough, the hammers returning which I also get on my acoustic grand piano FWIW, if you quickly strike a key and let it back up without having it hit the key bed. That particular feature you do not get in all digital actions and perhaps not in all modern grand pianos for that matter. My grand is very old. But that feature I actually like, it gives a good feed back feel similar to my acoustic grand. I'll take the subtle noise in that case.
