More on Vorsetzer/Solenoid Player in Updated Threelogy Book:

Electrical Vorsetzer (true roboto) stood in front of the piano with a horizontal row of felted fingers

adjusted just above the keyboard, it looked like a mini piano with no keyboard. 
Push ups were a pain in the neck when it came to adjusting them to different pianos. 
Each piano is slightly different. The piano size, carpeting, flooring introduces another 
factor for height. Special test roll for adjustment were used in the pianola. 
The fingers on the push ups were supposed to be about 1/64 
of the inch (millimeter) away from the keytop on the piano. Adjustment had to be made every time 
a Push Up was pushed up to a new piano. The closer the fingers were positioned
the better sound it gave but that's not always the case, exact sound can never be 
100% reproduced because of different pianos, room ambiance, temperature, acoustics, etc. 
Original Pianola Push Up was pneumatic system, it had to be skillfully operated by artistic humans
                
                A solenoid player:

       It is not a pneumatic instrument as is with the Duo-Art featuring 
Pianola control levers (for Push Up systems). There were levers for different functions;
operator's attention was crucial or song's timing would be off key. 
Solenoid is an electrical machine, it has a coil of wire around 
an iron core. It becomes an electrified magnet when current passes through the coil.
The Pianola or Player-Piano is "interactive" with the Push Up system, whereas
the solenoid player (pianola, rolls were on the inside as of 1902
but did not become popular until 1905, first Vorsetzer was invented in 1902) simply depresses keys.
This was a semi-automatic Push Up pianola. Pianola is no more 
mechanical than the most skillful player, it is not automated per se.
It's a mechanical piano operated piano that uses a roll of perforated paper
to activate piano keys. Pianola always had more than one definition.
The pianola was originally a 58-note instrument. It reached its 
peak of popularity at the time when the Wells stories and Slowacki's 
superb poems, stories were re-published. Then the 65 note scale had become
commonplace and the emphasis was upon classical music and some jazz/foxtrot
but personally interpreted. Wooden and metal fingers with felt tips pressed down 
the piano keys, once the instrument had been rolled up to and adjusted for
the height of the keyboard (automatic vorsetzer was yet to come).        
Inside Pianola was invented in 1903, aka Inner Player by Welte Corp. 
It was an Inner Player Pianola or what we call a Player-Piano today,
a mechanism contained inside the piano cabinet.
Pianola is also called self playing piano. Pianola term is generic now.
Welte was a brand of reproducing player (for organs) mechanism developed by Welte 
and Sohn (Son) in Germany in 1887 (albeit primitive one). Other examples of
what we have today is Auto Pneumatic Action Company aka Licensee but it's so unreliable.
The Original Piano Player was invented in Germany in 1902, as distinguished from 
PLAYER PIANO (Pianola), which came a few years later. 185.203.136.243 06:44, 11 March 2024 (UTC)
