Hello everybody!
I intend to start learning piano so I decided to purchase an used, but in mint condition Kawai MP7 for 1000 euro. I know this instrument is too good for someone who has never touched a piano keyboard, but I like it most.
So the beautiful device came and I began to test it.
Immediately I noticed something very odd: All the keys of the highest octave seem to have the sustain permanently on!
No matter how long I press my finger on the key - the sound is like my finger does not leave the key at all.
This applies only for the first section of instruments - the piano sounds and the highest octave.
The other instruments did not have this.
I searched in the settings to fix this issue with no success.
I did a reset with factory state: still the same thing.
Is this normal or defect?
I was afraid to spend 1000 eu. for a defective device, so I sent it back to the seller.
Was it a mistake?
The sounds of the piano were overwhelmingly awesome with my Sennheiser HD 598 headphones. The keyboard soo nice to touch... All the controls very handy.
Only this sustain.. thing.. was bothering me.
So did I do a mistake to send it back to the seller?

Kind Regards,

On a piano, the highest notes have no damper, so they won't mute if you release the key.

So yes, the instrument was likely fine, and the behavior is expected for something that correctly models an acoustic piano.

Good choice for a digital! Garf is correct about the highest notes not being dampened. My Kawai MP6 is the same way. What will really drive you nuts is the fact Kawai also sampled the mechanical noises made when you press the the pedal down, along with the fact while sustaining your played notes, neighboring strings resonate while the damper petal is depressed, making for a more realistic 'ringing' sound. It's a neat digital piano, you are going to really enjoy it.

Peter, that's normal. From G6 upwards an acoustic piano does not have dampers and therefore the strings are free to vibrate. Digital pianos try to recreate the same experience.

As everyone else was saying, this is normal. Its an "open string resonance" because the upper strings (G6 upward) are open (ie: no dampers). So whenever you play one of those keys, there's no physical mechanism (ie: a damper) to stop it from vibrating.

At the risk of looking foolish, or admitting that you made a mistake, I'd recommend trying to re-purchase the MP7 as that was a good price!

Fingers crossed you can get it back before someone else snaps it up!

Best of luck!

Probably better to ask such questions before you return it! Or before you buy it...

I understand the panic about possibly having bought a defective DP, but it is a pity you weren't able to ask the questions before you returned it. You will see that many of the MP7 owners in this forum are very happy with their instruments.

All the comments relating to your post have been very useful. It is true, Kawai puts a lot of effort into very accurately recreating as many of the subtleties and characteristics of a real piano in their samples. This is very evident on the MP7.

I personally suffered a good example of initial "panic" when first trying out a MP7 in a store. I was intending to buy it, but the salesman and I noticed some weird issues, for which we did not have immediate answers, so I held off until we could resolve the questions. One issue was that the values in the LCD screen would randomly alter. We discovered later that the reason for this was that the salesman had connected a generic damper pedal into the dedicated damper pedal input...and you must only connect the supplied Kawai damper pedal into this input. (You can connect a generic pedal into a separate control pedal input and assign damper to it). I was also concerned that the Pitch Bend wheel did not operate on the main piano sounds and nor the drawbar organ sounds. We obtained technical advice from Kawai that this was part of the normal setup.

I hope you can see that there is a wealth of support and help when it comes to Kawai DPs, whether from Kawai themselves, or from satisfied users.

All the best.

Thanks everybody!
I should ask someone, but I don`t have friends who play the piano and it was a question of Take it or send it back. I didn`t have a chance to gather information about this.
Thank You everybody and cross fingers that I could take it back! :))

Best Regards,
