Middle C is louder than all the others...
Hello, I have a Casio WK-3800 keyboard with a problem... I have it set at its default Grand Piano setting with no other options selected. It just plays as a regular piano. No options used. Problem: the MIDDLE C key produces a LOUDER volume than any other key. It's at least twice as loud as any other key. That is the only problem. Do you know of any reason (other than a defective keyboard) that would account for just one key, middle C, to produce a much louder tone than any other key? Do you know how I can resolve this or do you think it's defective and must be fixed? I appreciate your time.
