Patent ID: 7528309

Claim:
An automatic player musical instrument for producing tones along a music passage having a repetition, comprising: a musical instrument including plural manipulators selectively moved for specifying the tones to be produced, and a tone generator connected to said plural manipulators and producing said tones specified by means of the manipulators moved for said tones; and an automatic playing system including plural actuators provided in association with said plural manipulators and responsive to a driving signal so as to move the associated manipulators for specifying said tones, and a controlling unit connected to said plural actuators for selectively supplying said driving signal to said plural actuators, a computer program running on said controlling unit so as to realize a plurality of functions including a searcher searching a set of pieces of music data expressing properties of tones to be produced in a music passage for certain tone producing events determined on the basis of certain pieces of music data in said set and expressing the tones to be produced in at least one repetition on one of said plural manipulators, a modifier connected to said searcher and modifying certain pieces of event data produced on the basis of said certain pieces of music data and expressing properties of said certain tone producing events so as to make at least one of said properties of said certain tone producing events uniform and a signal regulator connected to said modifier and regulating said driving signal to an optimum magnitude on the basis of said certain pieces of event data already modified so as to cause said tone generator to produce the tones in said at least one repetition through the movements of said manipulators on the condition that said at least one of said properties of said certain tone producing events is uniform.
