Onboard Speaker Flutter and Sticky Mod Wheel

[marksinger]

I love my PX-560 but a few days into owning it, I have noticed a slight "flutter" or warble when playing mid range keys using the "home base" Grand Piano sound. It happens only when playing through the onboard speakers. The problem isn't there if I listen through headphones which leads me to believe it's some kind of harmonic resonance type of problem with the speaker/case design. FYI, the keyboard is near but no flush against a wall. Surely though, that's an expected positioning for this kind of keyboard.

 

FYI, the keyboard is mounted on the CS-67 stand by Casio that is purpose built for this unit.

 

It's not the modulation wheel because that is firmly set to the zero position. Speaking of which, I find the mod wheel is a tad sticky at the zero end. Is that normal?

 

I've attached a sample sound.

 

Am I the only one experiencing this? Should I just return it to the store and get a replacement or will the new one be exactly the same?

that's the same for me. I went to few musical instruments shops and EVERY member of the PX family has got this silly piano sound on the C above middle C.

PX560 great instrument genarally speaking but ... the piano sound could be much much much better !!!

Thanks for your reply Luciano. I am regrettably returning the Casio today and instead getting a Juno DS88 which seems to offer more bang for the book. Keyboard feel may not be quite as good, but still very good for someone of my limited ability. The lack of speakers is moot if the ones on the Casio don't produce any decent tone anway.
