Harmony Vocals machine story...

Just got back from a gig at a VFW. There was an older lady of retirement age playing the piano in the hall as I loaded in. She sounded great and I had a brief conversation with her. I ended up talking about my new toy, the Vocal Harmonizer thinking she would not really know what I'm talking about. Her response was "Oh I have one in my Organ at home, I love the choir setting". On one hand I thought wow cool some Organs today not only come with a mic input but also have a harmony processor built in. On the other hand I was kind of shocked and glimmer got taken away from my new toy, a retired musician new exactly what I had and it was old news to her :(
