Would be better if you can record the noise.

I try to replicate the problem, but not sure I find what you find. I can hear very soft noise like a "muuuu", but I have to hit the note very very soft and noise is almost unnoticeable. Also, switching off reberb the noise goes away.

I doubt this is your problem because is so unnoticeable that I can't think someone can get annoy by it.

Could be that in your DP the noise is more accentuated than mine? Or maybe a setting increase noise? Or maybe is not the same noise than mine?

Switch reberb off and see if noise is there. If still there, make a recording so we can hear.

Thanks. I will record the noise and will report back. It is only there when you play softly and is gone when I strike medium or hard. Main thing I wonder is if it might go away with time.

gauguin, if what you're hearing is a characteristic of the piano sample (i.e. captured in the original recording), I don't believe it's something that will change over time.

Kind regards,

James,

yes I was wondering as well if it is due to the underlying sample but it is a little more complicated than that as it does not always come one. It only comes on when played "fairly" alone but then also not all the time. In my experience it is almost always there when you play piano. Turning the piano off and on again does help as well.
I just had it a lot today as I practiced the right hand of a soft piece today and then I had it almost every time when hitting D.

gauguin, if you are concerned by this behaviour, my recommendation would be to report it to the store from where the instrument was purchased, and/or the Kawai distributor in your country (e.g. Kawai America).

Kind regards,
James

Hi James and Daniel,

Just a quick update. The echo is gone when I turn off reverb. I will make a recording tomorrow.

Can't reproduce it now, but I heard that "ghost" noise multiple times already during long practice sessions. Sounded like some digital aliasing, like there was a filter failing. Especially the Mellow Grand preset, which I use often, has a lot of reverb. Seems the reverb implementation doesn't interact well with that specific sample.

I really didn't expect that to be an issue...


My $280 NP-31 Piaggero keyboard doesn't have that issue either and its AWM sound engine is from the stone age.

Hi,
Bought it yesterday and really like it.
My first (DP)piano.
Excellent help from local dealer.
Noticed a few minor things.
Have two extra monitors/speakers on a phones jack.
When selecting speakers on with phones output volume goes up (p45 manual).
This settings is not saved when saving settings (p47 manual)
Regards,
Hans

Indeed, speakers seem to go to maximum volume and the volume slider does almost nothing for them. Once you pull the phones out (even with the setting still on), everything goes back to normal.

Hi,

I made a recording of the strange echo I here when softly striking D4.
This uses the default reverb ("room"). Set your volume to low first as the recording is quite loud at first.
Here is the file:

I get the same noise. Is a soft "muuuh" after the note. Is hard to notes it. Not sure how you even find it.

I suppose only solution is turn off reverberation. Actually I always leave reverb off. Not because of this issue (since I didn't notes it before) but because I don't like the reverb effect on this digital piano.

Thank you for confirming it. So I suppose it's an ES100 "feature". I will submit it to Kawai techs as well to see what they say.
I actually like the default reverb and don't want to switch it off. I

I found/noticed it as I practiced the Sarabande of Bach Partita #2 which starts of rather softly.

gaguin, I can hear the characteristic you're referringto, however I get the impression that you artificially boosted the volume of the recording considerably in order to emphasise this sound.

I shall pass this MP3 on to my colleagues, however I'm afraid I cannot promise that any action will be taken to adjust the sound.

I also encourage you to contact Kawai America to report the characteristic, to ensure it is correctly logged.

Kind regards,
James

Kawai James,

Were you able to reproduce it on your ES100, too?

You are right that this only happens when playing rather quietly and it disappears when playing more loudly. Yet it does not appear with other keys: only happens with or sometimes around D4.
Incidentally I did not boost the recording: I am not much of a specialist and the level was set automatically by my recording device.
I will submit to Kawai USA, too.

I'm afraid I do not have an ES100 in my office for testing.



Ah, I see. My apologies for doubting your intentions.

Kind regards,
James

No worries KJames. Just wanted to explain what I did.

Just spent another hour practicing on my ES100. Just such a smooth piano keyboard!

Yesterday I sent an email to Kawai USA about this strange echo I hear after D4. Haven't heard back yet but I will let you know in case I hear back from them.

So I emailed Kawai about the echo/"moo" you can hear at times when pressing D4 softly.
They never got back to me. No matter, as Richter pointed out it is gone when you turn reverb off.

gauguin, which email address did you send your message to, may I ask?

Kind regards,
James
