Hi, I'm having an issue where some keys tend to drop in sensitivity while playing, it doesn't appear to be any specific keys. For instance, I'll play a scale and certain keys will just come out a lot softer, as if pressing it very lightly. Pressing it again usually rings the note as it should, but it's quite annoying. Is this a hardware issue? My software and firmware is up to date. If so, how could it possibly be fixed?
