Thanks! I think I get it, these high frequency overtones create that crystal ringing sound of a grand piano It just surprised me that the keys next to each other have such a different frequency spectrum. Apparently this is for balance. The more I play, the more I like it I used to play only on cheap pianos and for a very long time on a Soviet grand piano at a music school, but I already forgot how a grand piano should sound

Made a demo. Not sure how good its quality is )) sorry for loud breathing I played E4, E4 flat - high pitch overtones then F4 - no high pitch overtones Warning! sound volume may be too loud px870_e4_e4flat_f4_overtones_ext_mic.wav

Hi! I got Privia PX-870 and noticed that some keys in the center of the keyboard sound strange. They have very loud high-pitched overtones that even overpower the main tone. The range of keys is approximately C4 # - E4. Starting with F4, these overtones immediately become 2 times quieter. It is very clear and audible if you compare E4 and F4. Here is an analysis of the frequency spectrum. I never play Steinway Grand Piano, but don't think it sounds like this. I checked in the store on other PX-870 and got the same results. It looks like a problem with key sound samples or firmware. Do you have such problem or any ideas about it?
