I turned my Montage 6 on for the first time in a while and noticed that the piano sounds, Moody and Concert, cut out at random times. I can go up and down the keyboard one note at a time and some notes make no sound. (different keys at different times.) If I keep hitting one that was at first silent, it eventually starts playing. Also, I have several piano sounds where the top 4 keys don't make a sound. Is that normal on a Montage 6? Thanks!
I had a similar problem when my keyboard was exposed to high humidity. It cleared up after a week of being in a dry area. I'm not saying this is necessarily your case - only that the description sounds familiar and this is what the diagnosis and resolution was for me.

Anyone know off the top of their head how to do a hard reset on the Montage? Thanks.
