When using any of the Bank A piano sounds, and sustain pedal depressed, I get a strange sound when playing G above middle C. I have tried going to global and reloading bank A. Same thing happens. Any ideas???

Possibly it is the Piano Damper effect, usually included as an IFX for acoustic piano programs. You can turn it off or adjust its settings to your liking. With the effect ON, it activates when you step on the damper pedal (aka sustain pedal).
