Hi,
I have PX-S3000 and I noticed that when I play the 2nd F from the left, (that is the the 13th white key from the left) I hear a ringing high sound when holding the key for some seconds.
Same issue with the black F# key next to it. All the other 86 keys dont have this problem as far as i can hear although I heard it one time on the E as well.
It happens more or less on all piano tones (grand piano, mellow piano, bright piano etc) , exept the GMpiano that is behind a different menu (342).
First I thought it was audio feedback or the ever present ringing in my own ears, but when I release the key it is immediately gone.
Especially when I play the key hard the sound becomes audible after a short time.
I did a factory reset, but no change.
I hear this ringing or feedback sound both on the internal speakers and on a headphone.
I also caputured it in a .wav file
can anyone reproduce this, or is it just my own PX-S3000 ?
Or is this normal behaviour in a piano because of resonance ?
link to sympathetic resonance
Thanks
