Abstract: A percussion detecting apparatus and an electronic percussion instrument, which are capable of not only providing excellent percussion feeling, but also visually indicating a percussion pattern of a beat applied to a percussion surface, so as to serve for percussion practice as well as to increase interest in the percussion practice. A head of the percussion detecting apparatus is formed of an air-permeable material and has a light transmitting property. The head includes a percussion surface. A drum shell supports the head. A head sensor detects a beat applied to the percussion surface of the head and outputs a beat signal indicative of the sensed beat. A light radiating part is disposed on an opposite side from the percussion surface of the head so as to perform visual indication corresponding to a percussion pattern of the beat applied to the percussion surface, at least through the percussion surface, based on the beat signal output from the head sensor.

Abstract: In an electronic keyboard instrument (1) being an example of a musical performance apparatus having a musical operation unit, a unique musical performance apparatus is formed by an outer face of its exterior (2), and part or a whole of the outer face of the exterior (2) is formed as a temperature sensitive discolorable layer, for example, as shown by the hatched outer faces of upper side panels (22), lower side panels (23), and a back panel (25), so that at least part of the exterior (2) changes in color according to a change in environmental temperature or a temperature change caused by radiant heat by illumination of lights (34). In order to forcibly discolor the temperature sensitive discolorable layer of the exterior (2), it is preferable that heaters or Peltier modules are incorporated in the exterior (2) and electricity is supplied thereto for enabling heating, or heating and cooling.

Abstract: A keyboard apparatus which is capable of imparting a natural key depression feeling with a definite and positive load change, with a simplified construction. A key touch feeling-imparting mechanism imparts a predetermined key touch feeling to a key when it is depressed. The key touch feeling-imparting mechanism is comprised of a receiving part provided on a support member, and an elastic engaging unit that has one end thereof held by a key operating part of an associated key and another end thereof slidably engaged with the receiving part.

Abstract: An electronic musical instrument which can realize a choking effect by a simple operation. The electronic musical instrument is constructed such that a neck provided with a fingerboard is fixed to a body. A plurality of (twelve) fret operating elements are provided for each of six sounding channels. The body is provided with a string input section and an arm, and six stringed operating elements are provided for the respective sounding channels. For each sounding channel, a tone generator generates a musical tone at a pitch determined by the corresponding fret operating element and in sounding timing determined by the corresponding stringed operating element. When the arm is operated, a CPU provides control to apply a choking effect to a musical tone for a sounding channel, in which the musical tone is being sounded, by raising the pitch of the musical tone by a predetermined amount.

Abstract: A sensing device is constructed by a sensor case which is attached to a bottom surface of a footwear (e.g., sole of a shoe) and which contains a piezoelectric sensor, a sensor fixing member, a disc plate pressure member and an annular elastic member. The sensor fixing member has elastic deformability so that the sensor fixing member is located to face with the disc plate pressure member with an air gap in which the sensor fixing member is capable of deforming within a limit of elasticity thereof. Thus, it is possible to perform musical tone control in response to an output of the piezoelectric sensor when a foot motion is applied to the footwear. In addition, a musical tone control apparatus of a percussion instrument type is constructed using a pad unit stored in a pad storage portion of an upper case. Herein, the pad unit is constructed by a pad skin unit and a sensing unit.
