Animated Keys of an Upright Pianola
By Jim Perkin
Hi, Does anyone have diagrams or schematics or photographs showing
how the keys of an upright Pianola were attached so as to animate when
the roll played? I have a 'UK' Aeolian half Duo-Art Steck which of
course never had animated keys. I believe that the American Pianolas
did (a lot of the pianola examples on YouTube have animated keys).
I have numerous diagrams showing the cross-section of a pianola showing
the pneumatic stack and hammer action but none of them appear to show
this linkage (if it is a 'linkage'). Is it also true that with some
players this function could be turned on or off?
I realise that if you were to weight the keys at the front they would
fall forward as the whippen lifts, but I imagine this is not how a
factory built one works. Any info would be appreciated.
