Odd Happening today at church

We were in the middle of a Hymn, when the organ suddenly went crazy. It was if all keys and options were pressed at the same time. At first I thought she is really taking some liberties with the music, and then realized something was terribly wrong. She held her hands up to show she was not doing anything. This is a brand new state of the art organ for our church. She had to switch to piano. Oman? The reverand got up and just said Amen! It was weird and creepy.
