ABSTRACT:
A sensor arrangement for an automatic piano player apparatus is provided. The sensor arrangement includes a plurality of switches which are operatively associated with a rotatable shutter in the hammer system of the automatic piano player. When the hammer system is operated to strike a string of the piano, the cooperation between the rotatable shutter and the switches produces output information which includes the string-striking intensity information and the state of condition information of the damper that is normally in contact with the piano string. With this information, the various play techniques such as staccato, legato, continuous key-striking and the like may be reproduced with great fidelity by the automatic piano player apparatus.
