I have recently purchased an FP-4 and noticed a "tinny" sound from the middle to the upper areas of the keyboard when using the piano sounds. It is more apparent the harder that I play. I can hear it from the speakers or via the headphones. Other than this it sounds fine. Anyone have any experience with this?
I've noticed a sound. It seems more of a scratch or click. I thought it was the key not being depressed squarly or the nose of fingers hitting the keys if that doesn't sound too strange. Doesn't always do it and when I go up the keyboard it is faultless. However depressing some of the black keys at a slight angle will produce a 'sound'. It seems more of a machanical noise rather than a generated noise.
Old post, but in case someone is still having this kind of a problem. I found out that when I had standard MIDI-cables connected on my FP-4 and sequencer(Cubase) wasn't running, it affected the piano sounds in annoying way. Some keys in a middle of the board created a sound that you might call "tinny". Problem solved by replacing MIDI-cables with USB-cable.
That's MIDI echoing back from the MIDI interface, my Unitor 8 does the very same thing if not talking to a computer..
Local control allows you you to disconnect the keyboard from the sound engine, problem solved.
