Keyboard instrument having catcher stopper for silent performance on keyboard.

摘要

An acoustic piano (1), an electronic sound producing system (3) and a controlling system (2) form a keyboard instrument for selectively producing acoustic sounds and electronically synthesized sounds, and the controlling system has a catcher stopper (2c) for restricting rotations of catchers before hammer heads strike sets of strings in the electronic sound producing mode, thereby giving the unique piano key-touch to a player without mixing noise with the synthesized sounds.
