Simulating muting in a drive control device for striking member in sound generation mechanism

摘要

A sound generation mechanism, provided with a string for generating a vibration sound in response to striking by a hammer, is automatically played in accordance with performance data. The performance data include striking data (note-on event data) for designating timing at which the string should be struck by the hammer, velocity data indicative of an intensity of the striking, and muting data (soft pedal data) for controlling muting. A controller determines drive start timing of the hammer in accordance with the velocity data in such a manner that the string is struck by the hammer at the timing designated by the striking data and performs control such that the drive start timing is advanced in accordance with the muting data. Thus, the string is struck at the striking timing designated by the striking data, but also muting control is performed in accordance with the muting data.

1. A drive control device for a striking member in a sound generation mechanism, the sound generation mechanism including a sounding member adapted to generate a vibration sound in response to being struck by the striking member, said drive control device comprising:
a reception section adapted to receive performance data, the performance data including striking data for designating striking timing at which the sounding member should be struck by the striking member, velocity data indicative of an intensity of striking, by the striking member, of the sounding member, and muting data for controlling muting of a sound; and a controller adapted to determine drive start timing of the striking member in accordance with the velocity data in such a manner that the sounding member is struck by the striking member at the striking timing designated by the striking data, and perform control such that the drive start timing is advanced in accordance with the muting data.
