Patent ID: 7238873

Claim:
An automatic player musical instrument for a performance without any fingering of a human player, comprising: a musical instrument including plural combinations of links selectively actuated by said human player for designating tones to be produced, and plural tone generating members selectively activated by said plural combinations of links for producing said tones; and an automatic player associated with said plural combinations of links, and including at least one actuator having a current path coupled with inductance and responsive to a driving signal flowing through said current path so as to exert force on a predetermined link of one of said plural combinations of links, thereby actuating said one of said plural combinations of links, a data processor analyzing pieces of music data so as to determine target positions of said predetermined link periodically varied, a target value of current of said driving signal for bringing said predetermined link from one of said target positions to the next target position at the end of a time period without consideration of said inductance and a temporary value of said current to be supplied to said current path in an early stage of said time period so as to make said predetermined link closer to said next target position than the predetermined link driven with said driving signal at said target value and a driving circuit connected between said data processor and said at least one actuator, supplying said driving signal at said temporary value to said current path in said early stage and varying said driving signal from said temporary value to said target value at the end of said early stage.
