ABSTRACT:
In order to give piano-like key touch to a player in an electronically sound producing mode, a keyboard incorporated in a musical instrument is linked with key action mechanisms associated with hammer mechanisms, and a stopper blocks the hammer shanks before the hammers strike the strings so that noises are not mixed with synthesized tones.
