<Overall External Configuration> FIG. 1 is a plan view of an electronic musical instrument apparatus according to an embodiment. This electronic musical instrument apparatus comprises an electronic percussion instrument 8 shown in the upper part of FIG. 1 and an electronic keyboard instrument shown in the lower part, and a signal from the electronic percussion instrument 8 is transmitted to the electronic keyboard musical instrument via a transmission cable 9 as transmission means. It has become. Hereinafter, the electronic percussion instrument 8 will be referred to as a pad rhythm operation device.
A keyboard 1 and a sound emitting section 2 are provided on the front side of the electronic keyboard instrument, and a power switch 3 is provided above the sound emitting section 2. Above the keyboard 1, a pad rhythm operation unit 4, a chord selection key 5, a rhythm selection key 6, and a melody tone color selection key 7 are provided from the left. The pad rhythm operation unit 4 has four pad switches A1, A2, A3, and A4 are provided, and pad tone color selection switches A5, A6, A7, and A8 are provided at the lower edge of each of the pad switches A1 to A4. The pad switches A1 to A4 are used by the sounding unit 2 to emit a single-shot decay sound such as a percussion instrument sound when pressed, and the pad timbre selection switches A5 to A8 are used to select the decay sound of this pad. The tone is selectively switched to a bass drum, a low bongo, or the like.

The chord selection key 5 includes a one-finger mode for automatically performing a chord playing of the accompaniment of the keyboard 1 with one finger, a finger mode for automatically holding a chord, and a normal mode for performing a normal melody. Switching to each mode. The rhythm selection key 6 is used to selectively switch the contents of the automatic rhythm performance to lock, disco, or the like. The melody tone color selection key 7 is a key for selecting and specifying the tone color of the melody tone played on the keyboard 1 as a piano tone, a guitar tone, or the like.

This electronic keyboard instrument body is provided with a pad rhythm operation device 8 having exactly the same configuration as the pad rhythm operation section 4 and having pad switches B1 to B4 and pad tone color selection switches B5 to B8 via a transmission cable 9. When the pad switches B1 to B4 are pressed and operated, an attenuated sound such as a one-shot percussion instrument sound is emitted from the sound emitting unit 2.

Of the pad switches of the pad rhythm operation unit 4 and the pad rhythm operation device 8, A1 and B1, A2 and B2, A3 and B
3, A4 and B4 are set to the same pad tone, respectively, and the corresponding pad tone selection switches, A5 and B5, A6 and B6, A7 and B
7, the timbre setting is made with the timbre operated later of each of A8 and B8. And each pad tone selection switch A5 ~
Light emitting diodes 10 are provided on A8 and B5 to B8, respectively, and the light emitting diode 10 corresponding to the pad tone color selection switch which is operated later is turned on to indicate the currently set tone color. A1 and B1, A2 and B2 of this pad switch,
When at least one of A3 and B3 and A4 and B4 is operated, the attenuation sound is emitted.

<Overall circuit configuration> The pad-on signals corresponding to the pressing operations of the pad switches A1 to A4 and B1 to B4 are A1 and B1, A2 and B2, A3 and B3, A4 and B4.
From each of the two through OR gate 15 ...
The pressing operation is provided to a pad on / off detection unit 11 shown in the figure to detect the pressing operation. For this reason, the output of the pad switches A1 to A4 and the pad switches B1 to B4 is controlled in a logical OR relationship. This pad-on signal is output from the pad tone selection switch A5.
A8 and B5 to B8 are sent from the CPU 12 to the rhythm sound generator 13 together with the timbre data specified by B8 to generate a single-shot attenuated sound signal such as a percussion instrument sound such as a bass drum or a snare drum. The rhythm sound due to this decay sound signal is emitted.

The operation of the pad tone selection switches A5 to A8 and B5 to B8 is CPU1
2 and the corresponding light emitting diodes 10 are turned on. Further, when the pad on / off detection unit 11 detects the pressing operation of the pad switches A1 to A4 and B1 to B4, an interrupt command signal is given to the CPU 12, and the sound emission processing of the pad attenuation sound is performed with priority. Will be

[Operation of Embodiment] In order to perform the keyboard performance and the decay sound performance in parallel, first, the power switch 3 is turned on, and the rhythm control device 8 is connected to the electronic keyboard instrument body via the transmission cable 9. The pad switches B1 to B1 of the put rhythm operation device 8
The tone of B4 is designated by the pad tone selection switches B5 to B8 or the pad tone selection switches A5 to A8 on the main body.

In this state, the player on the put rhythm operation device 8 side has only to press the pad switches B1 to B4 in accordance with the progress of the music, and the ON signals of the pad switches B1 to B4 are used as the pad tone selection switches B5 to B8. Is transmitted to the main unit via the transmission cable 9 together with the timbre data, and the rhythm attenuation sound is emitted. At this time, the melody sound is emitted by the operation of the keyboard 1 of the player on the main body side, and even if the player presses the pad switches A1 to A4 of the pad rhythm operation unit 4, the rhythm is similarly changed. The decay sound is emitted.

Thus, one person can play the keyboard with the electronic keyboard instrument body, and the other person can play the rhythm with the put rhythm operating device 8.

In the above embodiment, the means for controlling the output in a predetermined logical relationship is the OR gate 15, but a NAND gate 16 as shown in FIG. 3 may be used. In the embodiment shown in FIG. 3, one end of the pad switches A1 and B1 (the other pad switches have the same configuration) is grounded, the other end is input to the NAND gate 16, and the high-level voltage is supplied through the resistors 17 and 17. Connected to the power source. When both the pad switches A1 and B1 are off, a high level signal is given to both input terminals of the NAND gate 16, and the output of the NAND gate 16 is at a low level, but at least one of the pad switches A1 and B1 is turned on Then, a low level signal is given to at least one of the input terminals of the NAND gate 16, and the output of the NAND gate 16 becomes a high level, and the pad attenuation sound is emitted. Also in this embodiment, the output of the pad switch A1 and the output of the pad switch B1 are controlled in a logical OR relationship.

The processing of the logical sum of the outputs of the pad switches A1 to A4 and the pad switches B1 to B4 may be performed in the pad on / off detection unit 11, or may be performed by the flow processing in the CPU 12. Further, in the above embodiment, the pad switches A1 to A4 and B1 to B4 are of the push type.However, the pad switches may be of the push type that is simply pressed. The pad rhythm operation unit 4 may be detachable from the main body of the electronic keyboard instrument, and the pad rhythm operation unit 8 may be replaced by a pad rhythm operation unit. An electronic keyboard instrument with a rhythm operation unit 4 may be connected to the electronic musical instrument main body. In short, any instrument may be connected as long as it can issue a sound emission instruction of the attenuation sound. The connection between the main body of the electronic keyboard instrument and the put rhythm operation device 8 may be electrical, light such as infrared light or laser, ultrasonic wave, wireless, etc. The timbre of each rhythm sound with the operation device 8 may be a different timbre.

[Effects of the Invention] According to the invention, (a) a continuous rhythm including a rhythm can be performed based on a performance operation of a plurality of users, and (b) especially a first rhythm operation means of the first user. Rhythm music performance based on rhythm performance operation
(C) a melody tone performance based on a melody performance operation on the keyboard means of the user, or (c) a rhythm tone performance based on a rhythm performance operation on the first rhythm operation means of the first user;
