Good point Gary.

Before I was having this problem with my PSR3000, I had been performing with it for about a year and a half with the X stand in the highest position as I perform standing up. This would put the least amount of pressure on the middle of the keyboard.

My keyboard is on an H stand right now, and I pressed down in the middle and nothing happens. I have had the keyboard back from the technician for about 3 weeks, and the problem has not repeated itself.
