Chosen Solution
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. Thanks. Anthony
Someone came up with almost the same problem only a couple of weeks ago. See Problem with yamaha P95 Keyborad That was on a Yamaha keyboard but it looks like the same answer should be applicable to yours.
On my Casio Privia there is a function labeled “touch response” (functions are labeled above keys, this particular one is the furthest right function labeled on my keyboard; other models may differ, see your user manual). Press and hold “function” while pressing the affected key (middle C in your case) and choose the “0” under touch response. This fixed it for me.
