摘要:
A hammer sensor incorporated in a keyboard musical instrument monitors a motion of each hammer assembly, and a controller not only determines a hammer velocity and an impact time for generating a set of music data codes representative of a music performance but also measures an actual distance between the hammer sensor and an impact point against a music string on the basis of a forward trajectory and a backward trajectory measured by the hammer sensor; thereby allowing a worker to easily adjust the hammer sensor to an appropriate position.
