@MrAntotonio Those machines used pneumatic steering of the valves because that enabled them to operate the valves with a wider, more realistic technique. It was more than just a "yes-no" digital decision. It was "which key- how hard- how long?" Before microphones and amplifiers were used to make "electric recordings" ( 1926 )on, famous pianists like Rubinstein sat down at mechanical pianos which recorded their individual style how and when they played the keys, not just which key in which order.
@MrAntotonio You see the little bellows on the right hand side, being pumped up and down? They make a vacuum in the tube which lies under the piano roll paper. The paper has holes and so has the tube. When the hole in the paper slides over the hole in the tube the vacuum collapses and that releases the hammers. When the hole is bigger, the hammer drops down harder.
Mostly the holes in the roll were made without anybody playing the music, but some of those machines recorded "their" pianist.
Have your considered getting the piano tuned? :D
