I bought my FP-10 a few weeks ago and am absolutely loving the keyboard so far! I have noticed something though within the past week or so. Some of the keys on my keyboard make a particular clicking/rattling noise when I press them at anything more than a light touch. The keys I've noticed this on are the black keys in between middle C and the octave above E. I guess I sort of expected this behavior after a few years down the line possibly, but since I bought the keyboard so recently, it raises a serious concern with me. Since it's kind of hard to put into words the noise they're making, I recorded a soundbite with my phone and uploaded it to Google Drive.
Have a listen (FYI I just listened to this back and it seems my phone didn't pick up exactly how loud it is, it's actually just a little bit louder than how the soundbite portrays it):

After contacting Roland support about it, they responded with, "According to our head service technician what you are hearing us normal. Even acoustic pianos have “key noise.” He said it is nothing to be concerned about."
Is that true? Do I have nothing to be worried about?
