A keyboard chassis has an upper limit stopper. A key extending a predetermined length in a front-rear direction is disposed on the keyboard chassis. A key support mechanism supports the key from below, and causes, upon depression of the key, the depressed key to operate such that the key pivotally moves about a virtual pivot located rearward of a rear end of the key. An upper limit position regulation portion provided on a lower portion of a front end of the key regulates an upper limit position thereof by contacting the upper limit stopper from below in a key-released state. A key rear-side stopper provided on the keyboard chassis is contacted by a rear end of the depressed key from below before the upper limit position regulation portion contacts the upper limit stopper, when the key returns to its original position before key depression.

A keyboard device for a keyboard instrument includes a keyboard chassis, a key disposed on the keyboard chassis, and a key support mechanism which supports the key from below and causes the key to operate such that the key pivotally moves about a virtual pivot. One of a first arm rear-side connecting portion and a second arm front-side connecting portion includes an engagement shaft extending in a left-right direction, and the other of them includes an engagement recess which has a U shape in side view and open in one of a front direction and a rear direction and is engaged with the engagement shaft. A cushioning member in sliding contact with an inner surface of the engagement recess is mounted on the engagement shaft in a state covering an outer peripheral surface of the engagement shaft.

The Thumb Bar Controller is a bar that runs the width of the electronic musical keyboard playing area, (plus whatever is needed for the lever attachment), connected by two armsrests just below the top, and approximately one inch away from the keys. It gives the performer control over two (or more) functions with the thumb of the playing hand, that would otherwise require the other hand or foot pedals, allowing a person with the disability of one arm/hand, to be as proficient as a person with two. It can be used for controlling pitch bend, modulation, MIDI specification controllers, various electronic controls, and product specific controls. The bar can be attached in numerous ways, could use a variety of spring type mechanisms to control it. It can be mounted externally or made as an integral part of the keyboard, with openings for the bar connections and movement required.

A system includes an electric stringed instrument with a remotely controllable electronic configuration. A system includes a remote control for configuring the electronics of an electric stringed instrument. A system includes a remotely controllable electric stringed instrument, a remote control for configuring the instrument, a MIDI controller, and cords interconnecting the system.

A control device (1) for controlling the sound of an electric musical instrument has a tread plate (2) and a signal generator (3). The tread plate (2) is mounted pivotally about a first axis (4a) and is mounted pivotally about a second axis (4b). The signal generator is configured such that it generates a first electrical signal for controlling the sound and a second electrical signal for controlling the sound, the first electrical signal being the result of a rotation of the tread plate (2) about the first axis (4a) and the second electrical signal being the result of a rotation of the tread plate (2) about the second axis (4b). A control system comprises a control device of this type and the electric musical instrument.

A rotation mechanism includes a shaft portion, a bearing portion, a protruding portion, and a stopper. The bearing portion configured to rotate with respect to a predetermined axis as a center of rotation and configured to slide relative to an outer periphery of the shaft portion. The protruding portion protrudes from the shaft portion. The stopper is integrally formed the bearing portion. The stopper faces the protruding portion. A length of the protruding portion in a direction in which the protruding portion protrudes is larger than a distance from the center of rotation to a sliding portion where the bearing portion slides relative to the outer periphery of the shaft portion.

An electronic percussion instrument and sound production control method thereof are provided. In an electronic cymbal, the output of a musical sound is controlled in accordance with the results of detection from a strike sensor when the strike sensor detects a strike on a striking surface. While the musical sound is output, if a user touches the striking surface, an electrostatic capacitance sensor outputs an output value in accordance with the contact condition so that the musical sound is attenuated in accordance with the output value while being output. Therefore, the user can attenuate the musical sound being output in accordance with the contact conditions on the striking surface, thereby silencing the musical sound by way of the action similar to that of the acoustic cymbal choke that is the action of touching the striking surface.
