Hi all. Anyone have a problem with the vocalist on the PSR 3000?. While doing a job yesterday and today, while pressing the button to change the vocal setting , nothing happens. The different voices( Mens choir, country, Womans choir etc. ) will not show up on screen. I tried a reset, with no luck. This is a new replacement keyboard and only a month old. My first 3000 had a bad mother board. I'm hoping that this is no the problem with this one. Any suggestions? Thanks, Bob L.
