My 2009 KB37 has two keys (low Ab and A) that always play midi tones as if the key was played hard. So pretty much every time I press the key at a given velocity it SOUNDS the midi patch as if I played it with force. Seems like a simple mechanical problem or perhaps a dirty connector on those keys?
Probably not under warranty and overall the keyboard is perfect for me but would rather not pay for repair if I can open it up and maybe clean something per your suggestions.
Please help if you can.
