Thanks for the video. I probably don't have a good enough ear to pick out the specific tones as I don't hear the sound with that video. All I know is that I can hear a metallic ring in that one note on the piano I have. I don't hear it with any of the other notes on the piano, so this one note just sticks out to me every time it is played. I appreciate you offering suggestions. I think I will return the piano as I don't think I can get past hearing that one sound while I play. Thank you.

Here is the sample I sent to Casio. The note that makes the sound is D5. If this is not broken, I'm wondering if you would have suggestions on how to mitigate that sound with that note. If I can't figure something out, I am thinking I will just return the piano as that sound is all I hear every time I play that note, and it makes my experience not enjoyable at all. I appreciate any suggestions you might have. Thanks. Ringing D5 Note.mp4

Just received an e-mail from Casio saying the metallic whining with my just one note is normal "harmonics" and "overtones." This doesn't make any sense to me as I would think all of the notes would have those same sounds and not just the one note. Disappointed in that response as it appears they are not willing to repair or correct this. It makes the piano very annoying to play as that note clearly makes a distinct metallic whining noise that the other notes of the piano do not and no recourse to get this fixed.

Just bought an AP-470 three weeks ago and I have the same problem with one of the D keys, only on the grand piano 1 and modern piano voices. Is this just a defect, or is there some way it can be fixed.? I don't recall it happening the first several times playing. I tried resetting the piano, but didn't fix the issue.
