Abnormal middle e noise on multiple Casios? #2891311

Recently (10 months ago) started practicing piano so excuse the lack of technical knowledge. I purchased a Casio CGP-700 a month ago and loved it except for one glaring issue. The middle e when held fades into an unnatural high pitched fading "noise". Adjusted every setting possible but didn't eliminate it. The "mellow" piano setting takes about half the volume of the noise away though. I sent it back but the replacement did the same thing!? Others in my household confirmed they heard the same issue. Everything else about this digital piano was ideal for me but that shrill tone really stood out when playing.

I decided to try a different route and went with a Casio PX870. It has a different sound engine so I felt I was in the clear. Low and behold I hear the same thing? Only about half as pronounced but still very distinct. No other tones up and down the keyboard make this noise. It isn't the physical key because when I adjust octaves the noise follows the middle e. I am so confused.

Were the two pianos in the same position within your room?

Sounds like room acoustics should be considered if both pianos with different sound generators were afflicted by the same/similar thing.

Good point. Same room but multiple positions in the room. Exact same noise with headphones though.

Bring your headphone and try different model at the store.

I spent a lot of time troubleshooting with Casio with no result. It's frustrating when you are so excited to finally have weighted key action and this happens. I'm certainly not going back to my Yamaha es220! Ha!

Sounds like a reverb thing. I've had that trouble from time to time with other models. Try knocking it off. Reverb is sometimes not modelled, and you'jj get the natural reverb of the recording room predominating.

What do you mean by knocking it off? Turn the setting off? I checked the reverb settings and none seem to improve the issue. You would think that would solve it completely.

Can you play a Chromatic scale around the E you are talking about and record it.

Attached is a simple iPhone recording of three notes, the middle e trails off to a whine. Am I imagining it??

I can definitely hear that. Can you make a recording of the audio output through line out? From the speakers it could definitely be room resonance (and not the DP).

Sounds like the tone is wavering between sharp then flat and try's to fix itself and goes to sharp then, I hear it. Download one of the piano meter/tuner apps and check all of the keys individually. How does it sound in an E minor chord or straight E chord? Could be room resonance too, sound does funny things when it bounces off of walls. Speakers on DP pianos are junk, the ones on my p515 are a joke. Its like I have a CFX that was shoved into a closet and I'm trying to get good sound out of it. Some of the center notes on mine do the same thing. My next move is a set of high end active monitors...

I just listened to it a few more times and to me the F sounds worse than the E. Its funny how individual ears pick up different things. You really have to listen to the resonance of the notes closely. All in all its not real bad....

Was this ever resolved? I have a PX-870 but haven't encountered this issue. Not yet anyway. It reminds me of a "wolf note" on a cello. And pretty much in the same spot - fourth position E on the third string on mine. grin

I'm not hearing the problem. Perhaps these shyte laptop speakers hide the warts?

But I do hear an abnormal decay. The decay is short and inconsistent.

If anything the sound is even more pronounced with headphones. So that eliminates the room positioning as an issue. I sent one of these back and was told it tested completely accurate so my shipping was not refunded. The replacements have exactly the same sound issue so apparently there is nothing to "fix" according to Casio. Due to how hard it is to repack a digital piano, I might just live with it and hope to upgrade a year or so down the line. I did go to the one music shop within driving distance and played multiple DPs from Roland and Yamaha (using speakers and also my headphones) and did not hear a similar issue.
