<P>PROBLEM TO BE SOLVED: To perform reproducing operation more faithfully by bringing an automatic playing piano under automatic playing control matching to individual musical instruments. <P>SOLUTION: The automatic playing piano has keys 1, solenoids 5 for driving the keys 1, and hammer sensors 8 for detecting string striking speeds (velocity value) of hammers 2. A table generation processing section 9 supplies a plurality of designated reference values Ref, measures respective velocity values obtained as a result of driving based upon the respective supplied reference values Ref, and records the respective measured velocity values while making them correspond to respective driving indication values. Further, the minimum value among the plurality of designated reference value Ref is variable based upon the measured velocity value. A table for output of the driving indication value corresponding to a velocity value is generated based upon the respective recorded velocity values, the respective driving indication values corresponding thereto, and the minimum value of the varied reference value. <P>COPYRIGHT: (C)2007,JPO&INPIT |
