摘要： A sound control device includes a selector, a sound signal generator, a switcher, and a controller. The selector is configured to select, based on a user operation, one piece of setting information among a plurality of pieces of setting information including at least one timbre group and one effect setting group. The sound signal generator is configured to generate a sound signal based on performance information and the selected setting information. The switcher configured to switch between a hold-enabled state and a hold-disabled state based on a user operation. The controller configured to control the sound signal generator to generate the sound signal such that in the hold-enabled state, even if the selection of the setting information is switched by the selector, at least the effect setting is maintained.

摘要： In a key switch (10), an inner dome (Din) starts to deform once a distal end portion (21) of the inner dome (Din) comes into contact with a base surface (93a) after an outer dome (Dout) starts to deform. A thick portion (25) extending straight and having a uniform wall thickness in a click generating portion (CL) has the thickness less than or equal to the minimum thickness of a thick portion (23) of an after stroke portion (AF). The degree of inclination of the thick portion (25) with respect to a center line (C0) (direction of pressing) is larger than that of the thick portion (23) with respect to the center line (C0) (θc>θa). Before the after stroke portion (AF) undergoes large deformation, the click generating portion (CL) undergoes buckling to cause a sudden decrease in a reaction force and generate a click feeling.

摘要： A keyboard device includes a plurality of transmission members which are displaced in response to a depression operation on each of a plurality of keys and a plurality of hammer members each of which provides an action load to a depressed key by performing a rotating motion in response to the displacement of a transmission member corresponding to the depressed key. The weight of the transmission member is set in accordance with the formation density of a plurality of ribs formed on a transmission body section. Therefore, the weight of the transmission member set in accordance with the formation density of the ribs can be provided to the key as a static load. As a result of this structure, an initial load on a key can be optimized, and a key depressing force on the key at the time of key depression can be favorably transmitted to the hammer member.

摘要： A keyboard assembly for a keyboard instrument such as an electronic piano is constructed using a key, a first moving member, a second moving member and a key-depression switch. Herein, the key is supported by a keyboard frame to have a capability of rotating up and down about a rotation center. The first moving member is arranged beneath the key and is subjected to rotary motion about a first rotation center. The second moving member incorporating a deadweight has a larger weight and a longer moving distance as compared with the key and first moving member respectively. At the key depression, mode a back portion of the first moving member rotates upwardly so that the second moving member normally located at a rest position is subjected to rotary motion about a second rotation center. Thus, the second moving member rotates backwardly, and, it is stopped at a contact position defined by a back portion of the keyboard frame. Thereafter, the second moving member is subjected to back checking by which the second moving member is slightly moved forward and is temporarily fixed in position as long as the depression of the key is maintained. The key-depression switch is located beneath the key and is turned on to produce a musical tone in response to the depression of the key.

摘要： An electronic musical instrument comprises a plurality of keys being displaceable relative to a support member therefor in response to depression thereof. A CPU detects velocity of depression of each of the keys from displacement of the each key caused by depression thereof, and also detects a pressure force or an impact force with which the each key urgingly contacts a stationary member at or near termination of depression of the each key. The CPU is responsive to the detected velocity of depression and pressure force or impact force, for determining initial touch information for a musical tone to be generated or at least one musical tone parameter, and for controlling the musical tone to be generated, based on the determined initial touch information.
