all the black keys from c1# up to and including d2# are making a loud clicking noise when i release them. It sounds as if they are hitting off the metal cover/chasis. All the other black and white keys are fine. maybe the foam between the keys and the metal chasis has came loose or something.
has anyone else had this problem? I would be interested to know what could be causing it as it sounds really nasty if release one of the low end black keys slowly or quickly
your advice would be appreciated!!!
