摘要:<P>PROBLEM TO BE SOLVED: To make possible simulation of variations in pressing-down load of a damper pedal of an acoustic piano, when not stepped on, according to the tone pitch to reduce the awkward feel of key pressing on the border of key ranges. <P>SOLUTION: The pressing-down loads Fx of individual keys in a stroke position STx, which is supposed to be the position immediately after a damper leaves the damped string in a key depression forward stroke of an acoustic piano according to the setting of the bending length of a hammer, are so set as to gradually decrease from the low sound side toward the high sound side; the difference DB in pressing-down load Fx between a first key K1a and a second key K2a adjoining each other on a border B corresponding to the border of key ranges differing in the presence or absence of a damper mechanism in the acoustic piano is greater than the greatest of differences D1 and D2 between pressing-down loads Fx of two other mutually adjoining keys in the keyboard part. <P>COPYRIGHT: (C)2012,JPO&INPIT
