In an earlier post I reported that I had experienced an intermittent fault with the MZ-X500 whereby Tones continued to sound after key release particularly on the E5 Key? Rick Sterling suggested I recorded these with the inbuilt Audio Recorder, when they occurred which I did. In turn my first MZ-X500 was returned for repair/replacement, with the recorded evidence, and a month latter I received a new replacement MZ-X500 under warranty. With no explanation of what fault was found with my first MZ-X500.
I have now had my replacement MZ-X500 for about four months... and guess what?.... I am experiencing the same intermittent problem yet again with E5 Key Tones still sounding on key release. I first noticed this fault within two months of ownership and again with the replacement MZ-X500 ....and I class myself as a careful non-heavy fist-ed player with a classical bent.
Repeated pressing the offending E5 key does not resolve the problem -which obviously cannot be attributed to a doggy key bed switch, BUT WHAT I HAVE DISCOVERED IS THAT WHEN I GO INTO TONE EDIT AND TOUCH KEY RELEASE NOMINALLY SET AT '00' FOR DEFAULT TONES AND RESET IT BACK TO '00' AGAIN, (EVEN MOVING THE KNOB BACK AND FORTH BY ONE DIGIT) THE FAULT DISAPPEARS... until the next time this annoying intermittent fault occurs which maybe a few weeks/months hence ? Similarly re-booting the MZ-X500 temporary resolves the fault -as I discovered and reported in my earlier post with my first MZ-X500
What is going on here?
If I am experiencing this same fault on my second MZ-X500 surely other users somewhere must be experiencing the same fault ?
Following my discovery that the fault is related to KEY RELEASE in Tone Edit, perhaps the fault can be resolved by a future Firmware Update ? Nevertheless CASIO need to look into this fault.
Otherwise the MZ-X500 is a fantastic keyboard I never tire of playing. -It's just this bug.
