Each switch 41, 42, 43 is connected via a wiring pattern on the printed circuit board 40. When it is electrically connected to the cord 45 and the switch 41, 42, 43 is pushed down to perform an ON operation, a predetermined electric signal (tone color switching signal) is transmitted to the input detection circuit 4 via the cord 45.

In this way, the tone color selection switches 41, 42,
Since 43 is provided, it is possible to instantly switch the timbre even during a performance by a simple operation. Configuration Example of Sound Plate 1 FIG. 4 is a diagram showing a cross-sectional structure of one configuration example of the sound plate 1 provided with the sound plate sensor 1A.

The sound plate 1 is composed of three lower electrode members 61L, 61C, 61R, which are separately arranged in parallel on the insulating substrate 60.
A conductive elastic member 62 and a conductive elastic member 62 formed to cover the upper surfaces of the lower electrode members 61L, 61C, 61R.
Of the upper electrode member 63, and an insulating skin member 64 laminated on the upper electrode member 63. The conductive elastic member 62 is made of, for example, foamed conductive rubber (specific resistance of about 1 to 10 [Ωcm]), and the upper electrode member 63 is, for example, highly conductive rubber (specific resistance of about 10 ^-2 [Ωcm]).
Consists of. Further, the skin member 64 is made of insulating rubber and may be formed continuously with the skin member of another sound plate.

Similarly, the upper electrode member 63, the conductive elastic member 62, and the lower electrode member 61C, The sound plate sensors 1C and 1R are constituted by 61R. That is, the sound plate sensor 1A
Is composed of three sound plate sensors 1L, 1C and 1R which sense the vibration at each divided position of the sound plate.

Mallet portion 16L of mallet 5L (5R)
By (16R), when the upper surface of the sound plate is hit, the distance between the upper electrode member 63 and the lower electrode members 61L, 61C, 61R becomes smaller, and the specific resistance of the conductive elastic member 62 decreases. Therefore, tone plates sensors 1L, 1C, resistance R _L of the 1R, R _C, resistance value of R _R decreases. Resistance R _L ,
The change in the resistance values of R _C and R _R is largest for the sound plate sensor near the striking position. In this way, the sound plate sensor 1L,

That is, first, according to the first aspect of the invention, a plurality of hit members (for example, sound plates) provided for a plurality of pitches are hit members (for example, mallets).
Each time the ball is hit by, the hit information corresponding to the hit state, the pitch information indicating the pitch corresponding to the hit member that has been hit, and the musical tone characteristic indicating means provided in the hit member (for example, Since the musical tone characteristic instruction information indicating the musical tone characteristic previously designated by the pitch bend operator 52) is sequentially output from the batting information output means, the batting information output means sequentially outputs the batting information, the pitch information and the musical tone characteristics. Each time the instruction information is output, a musical tone having a pitch corresponding to the output pitch information is indicated by the output musical tone characteristic instruction information at a volume corresponding to the output batting information. It is controlled so as to be generated with the musical tone characteristics. For this reason, for example, even if the player strikes with a striking member in both hands, the characteristic of the musical sound uttered according to the striking operation (for example,
Various effects such as sustain, tremolo, vibrato, etc., or pitch) are operated by a special tone characteristic instruction switch immediately before or during the beating performance according to the instruction of the tone characteristic instruction means provided on the striking member. It is possible to reliably control without doing so.

According to the second aspect of the present invention, each time a plurality of hit members provided for a plurality of pitches are hit by the hit member, hit information and hit information corresponding to the hit state received are given. The pitch information indicating the pitch corresponding to the hit member that has been received is sequentially output from the hit information output means, and therefore, the hit information and the pitch information are sequentially output from the hit information output means. The musical tone generation instruction means starts to generate a musical tone having a pitch corresponding to the outputted pitch information at a volume corresponding to the hit information. On the other hand, while the musical sound is being generated by the instruction of the musical sound generation instructing means, the musical sound characteristic instructing means provided in the striking member causes the musical sound characteristic (for example, various effects such as sustain, tremolo, vibrato, or the like, or Pitch bend) is instructed, follow the instruction,
The characteristic of the musical sound being generated is controlled by the control means. Therefore, for example, by holding the striking member in both hands,
Even when playing a batting performance, the characteristics of the musical sound already generated according to the batting operation (for example, sustain,
Various effects such as tremolo, vibrato, or pitch)
According to the instruction of the musical tone characteristic instructing means provided on the striking member, a special musical tone characteristic instruction switch is not operated by interrupting the striking performance during the striking performance.
It can be controlled reliably and quickly.

According to the third aspect of the present invention, in addition to the constituent elements of the first or second aspect of the present invention, a radio wave transmitting means for the tone characteristic instruction information is provided on the striking member side. And a receiving means provided on the side of the plurality of hit members for receiving the musical tone characteristic instruction information transmitted from the radio wave transmitting means. For this reason, since it is not necessary to route the connection cord between the striking member and the plurality of striking members, it is possible to perform a light striking performance without hindering the striking performance due to the wiring of the connection cord. You can
