Patent ID: 7435895

Claim:
An automatic playing system for producing tones through a musical instrument on the basis of a set of music data codes, comprising: an array of actuators provided for manipulators of said musical instrument, and responsive to a driving signal so as to move said manipulators of said musical instrument for producing said tones; a vibration sensor system for monitoring said musical instrument, and converting an attribute of said tones to a loudness detection signal expressing a quantity of said attribute loudness of said tones; and a controlling unit connected to said array of actuators and said sensor system, and including a parameter preparation unit adapted to preparing prepare control parameters optimum to said musical instrument and defining relation between pieces of music data stored in said music data codes and expressing the quantity of said attribute loudness of tone to be produced and pieces of control data used in adjustment of said driving signal to a magnitude on the basis of said loudness detection signal and said driving signal adjusted to testing magnitudes before an automatic playing for producing tones through said musical instrument on the basis of a set of music data codes, and a driving signal generating unit adapted to producing produce said driving signal on the basis of said music data codes and said control parameters in said automatic playing.
