Joe, George, Rodrigues, Jedi, and Uncle Dave:

Thanks to ALL of your for your quick responses, and a very 'special' BIG thanks to you Uncle Dave for explaining 'exactly' what the problem WAS. If I leave the footswitch disconnected (at startup) everything works fine. I now remember (light bulb) when this all began. I had switched Yamaha's default sustain pedal assignment from pedal #1 to pedal #2 a while back, because I needed to use the SAME pedal to trigger pitch bend as well, as for some strange reason, the PSR2000 only allows you to assign pitch bend to pedal #2. Coincidentally , it was Uncle Dave who had suggested switching the sustain pedal assignment to #2 in order to have pitch bend & sustain triggered from the SAME pedal). I'm so grateful I don't need to send my keyboard in for repair now. I was really beginnng to start breaking out in a sweat. Thanks to the support of all you wonderful friends on this board, it's back to happily gigging with the PSR2000. This KB realy is awesome, despite some of its minor quirks. - Scott
