Hi I've recently just treated myself to a PX350. Within days I actually contacted Casio to say everytime I used the sustain/damper pedal I was aware of what could be described as a noise resembling a gunshot sounding. Casio replaced the keyboard but again the same 'problem' exists. It only occurs in the piano bank and the other sound groups are unaffected. Is this a problem with how the samples have been recorded I wonder? I have tried other PX350s in various shops and it would appear this is a general problem. It is really noticeable when the output is put through an external amplifier. Any solutions folks?
