Well, I had it sent back to the shop for checking: as much as I tried Joe's good advice to Zen/Jedi the sound away it just wasn't the quality I expected... turns out the pedal unit was faulty, I guess perhaps the soft pedal was kicking in when it shouldn't have, which gave us a bit of a muffled sound, and correcting for that (with volume and brightness) may have given the dissonant noise. Or something else maybe? The shop wasn't too forthcoming, just said it was a faulty pedal unit. But anyway, got it back and with the pedal unit repaired, the sound is closer to the showroom sound 😁.

Thanks Brad and Mike! I appreciate your messages. To add, though, I've been playing piano for 45 years, from our cheapish upright at home to the grand at Coventry Cathedral, I've also owned two Yamaha CLPs (lower end) and never noticed such an irritating noise/resonance. It's quite off-putting. And I have tried the other piano settings, it doesn't change it. It really sounds like a process rather than a natural arising. If it was just on the Berlin eg then I would accept that they just recorded that, but as it's on all three, and I've never heard that on any other real piano, I am skeptical. Mike, you say as I have the damper resonance off there's no other processing: is there ANY processing I could have missed which would explain this noise? With respect, I really don't think it's "normal", at least in my near-half-century of playing pianos. Of course one explanation is my hearing has changed since younger days and I am more sensitive to the higher frequencies... 🙀 Or, bottom line, are there any settings that would reduce this? Cheers, James

Hi, I have a new GP-310, installed by Parsons in HK, there is a very noticeable "ringing" sound coming after playing notes and chords, particularly in the middle range. I get that there's supposed to be some "natural" resonance but this is quite an irritating high-pitched noise and it comes on about a second after the key pressed, it sounds very artificial and it is bugging me! On chords (even major chords) it's quite a dissonant sound. Sound file here from an F. Normal play and then I jacked up the 2-2.5kHz on the equaliser to highlight the resonant sound more, you can see in the sound file screenshot below it comes on quite strong. B flat major chord is really bad, to the point I thought there was some other noise in the house or the windows being set off by the frequency (it's not, it's the same with headphones or recorded straight to SD as this sound file was). I can reduce it a little through the amp (treble lowered but using the "bright" Berlin sound so it's not too muffly) but I wonder if there's a hardware/firmware fix for this? Perhaps the machine is trying too hard to be a real piano but I never heard a real piano make such a dissonant and awful buzz. Or is it faulty? I have all the "resonance/damper" settings turned OFF and it hasn't made any difference. Any help appreciated. Incidentally I don't get this when using the 310 as Midi controller with another Grand, so it's entirely the Casio sound engine on board doing this. I think 😅 Thanks! James .
