Pianodano,

The key contacts are not keyed in sequence but simultaniously. All nine fingers go down and contact their respective busbars at the same time. This is nothing new. I repaired organs for ten years and many companies did the same thing. Conn was a big one to do this also. I beg to differ that a good player can control this in real time while playing. Whoever told you this had no idea of what they spoke or they were pulling your leg.
