FIG. 7 is a block diagram of the tone control circuit of the embodiment. In the figure, reference numeral 10 denotes the first embodiment or the second embodiment.
As described above, the rotary operator according to the embodiment includes the rotary encoder 3 or 9. A predetermined operation element 20 includes a start / stop switch for instructing reproduction and stop of automatic performance;
Alternatively, in the synchro start mode, it is a performance operator such as a keyboard, and an instruction to start / stop automatic accompaniment is given to the address controller 30 by the predetermined operator 20. The address control unit 30 generates an address for reading the performance data from the automatic performance memory 40, and the performance data is output from the automatic performance memory 40 according to the address given from the address control unit 30. The performance data is supplied to a sound source 50, which generates a tone signal in accordance with the performance data, and the tone signal is converted into an analog signal by a digital / analog converter (D / A) 60, and an amplifier or speaker Sound System (SS) 7
At 0, a tone is generated.

The speed data obtained from the output of the rotary operation element 10 (the output of the rotary encoder 3 or 9), that is, the rotation speed of the operation unit 1 or 6 (the compact disk 6 of the second embodiment), and the direction data, that is, the operation unit The rotation direction of 1 or 6 is supplied to the address control unit 30 or the sound source 50 or both the address control unit 30 and the sound source 50 via the switching control circuit 80. Further, the output of the rotary operator 10 is supplied to the sound source 50 via the control switching circuit 50a. The address control unit 30 and the sound source 50
The control switching circuit 50a will be described later. Thereby, the address control unit 3 is operated in accordance with the operation of the rotary operator 10.
At 0, the read address of the performance data of the automatic performance is controlled, and modulation or various effects are added to the automatic performance.

FIG. 8 shows the address control unit 30 and the rotary operator 1.
FIG. 9 is a diagram showing a processing circuit for the output of the rotary encoder 3 (or 9) of 0, showing a state in which the switching control circuit 80 is switched to the address control unit 30 side (the switching control circuit 80 in FIG. Is not shown). The address control unit 30 includes an address counter 30a.
The digital output "1" is supplied to the reset terminal R of the address counter 30a and the tempo clock counter 30b via the stop terminal of the start / stop switch 20 (specific operator 20). You. Thereby, the address counter 3
0a and the tempo clock counter 30b are both reset. Start / stop switch 2
When 0 is operated to the start terminal side, the reset state of the address counter 30a and the tempo clock counter 30b is released, and the tempo clock counter 30b starts transmitting the tempo clock to the address counter 30a. The counter 30a outputs the address value to the automatic performance memory 40. Thereby, the automatic performance is started.

On the other hand, the output of the rotary encoder 3 (or 9) is output from the speed detecting unit 101 and the direction detecting unit 102.
Is input to the operation unit 1 (or 6) by the speed detection unit 101.
Is detected and the speed data is supplied to the tempo clock counter 30b. The direction detecting unit 102 detects the rotation direction of the operation unit 1 (or 6) and supplies direction data to an up / down input terminal (U / D) of the address counter 30a. Tempo clock counter 3
0b changes the output frequency of the tempo clock according to the speed data. The address counter 30a switches the address counting operation in the increment direction (increase) or decrement direction (decrease) of the count value according to the direction data.

With the above configuration, the operation unit 1 (or 6)
If the rotation speed is increased, the output timing of the address value (address of performance data) output from the address counter 30a is increased, so that the reproduction speed of the automatic performance is increased. If the rotation speed is reduced, the output timing of the address is delayed. The playback speed of the automatic performance becomes slow. In addition, when the address value changes in a direction of increasing according to the rotation direction of the operation unit, the method of reproducing the automatic performance becomes forward reproduction,
When the address value changes in a decreasing direction, reverse reproduction is performed. This gives the effect of the scratch record method to the automatic performance. Alternatively, only the direction data may be input without inputting the speed data, and the address counter may be automatically started when the start switch is turned on, and the data may be reversely read only when rotating in a specific direction.

In the above description, the case where the effect of the scratch record method is applied to the automatic performance has been described. For example, as in the second embodiment, a keyboard electronic musical instrument or an electronic musical instrument equipped with another performance operator , The effect of the scratch record method can be provided. In this case, the predetermined operation element 20 corresponds to a performance operation element such as a keyboard, and the sound source generates a musical tone based on performance data such as a key code and touch data output by operating the predetermined operation element. Therefore, the output of the rotary operator 10 is supplied to this sound source to control the effect of the scratch record method.

FIG. 5 shows an example of control for this sound source.
A description will be given together with an example of the control of the sound source 50 for the automatic performance shown in FIG. FIG. 9 shows the control switching circuit 5 connected to the sound source 50.
0a, and shows a state in which the switching control circuit 80 (FIG. 7) is switched to the sound source 50 side (note that FIG.
In FIG. 9, the switching control circuit 80 is not shown. ).
The control switching circuit 50a switches and outputs the output of the rotary operator 10 to a plurality of input terminals of the sound source 50. By switching the input terminals, the “total pitch” (pitch of all sounding channels) and the “UK pitch” (some keyboards obtained by dividing the keyboard portion into two parts) of the sound source 50 by, for example, speed data (rotational speed data). Pitch amount to raise or lower the fundamental tone corresponding to the key operation of the melody keyboard part by 1 cent to 1200 cents), "vibrato" (vibrato speed or depth),
"Panning" (sound image localization), "Total volume"
By modulating various tone control parameters such as (volume of all sound channels) and "real-time volume" (volume with respect to an externally connected keyboard), various tone controls can be performed.

In the above embodiment, the rotary operation element 10 controls the rotation of the operation section 1 (or 6) by the rotary encoder 3.
(Or 9).
As indicated by 0, the rotation of the operation unit 1 (or 6) may be detected by the volume 110 instead of the rotary encoder. In this case, the output (analog voltage value) of the volume 110 is converted into digital position data (data of the rotation position of the operation unit 1 (or 6)) by the A / D conversion circuit 120, and the position data is converted into, for example, the tempo clock. It is supplied to the counter 30b. Thereby, the operation unit 1
For example, the speed of the automatic performance changes according to the rotation position of (or 6).

When the volume is used as described above, the rotatable range of the operating unit 1 (or 6) is limited, but the operating unit 1 (or 6) can be rotated within the rotatable range. I just need. In this case, the rotational speed and the rotational direction of the operation unit can be detected by differentiating the position data with respect to time, and based on the data on the rotational speed and the rotational direction, as in the case of the rotary encoder, automatic detection is performed. The performance speed and the playback direction can be controlled.

The automatic performance apparatus (FIG. 1) of the first embodiment has two systems of automatic performance systems.
The automatic performance by the system is synthesized by the circuit shown in FIG. The system I outputs the automatic performance data according to the preset sequence, and the system II outputs the automatic performance data to which the effect of the scratch record method is added as described above. Then, the sound source circuit 51 and the sound source circuit 5
2 are input to the mixer 53 and the volume detection circuits 54 and 55, respectively.

The volume detection circuits 54 and 55 detect an envelope and the like from the input tone signal and output volume data to the three-dimensional table 56. The three-dimensional table 56 outputs the ratio data corresponding to the volume data of both systems I and II to the mixer 53 with the input volume data of both systems as arguments, and the mixer 53 responds to the ratio data. The tone signals of the two systems are synthesized according to the ratio and output to the D / A conversion circuit 60, and the sound system 70 generates a tone.

Here, the volume of the tone signal output from the tone generator 51 and the tone generator 52 is controlled by the slider d shown in FIG.
The operation changes linearly. That is, as the slider d is moved to the left, the level of the tone signal of the tone generator 51 gradually increases, and
The level of the tone signal gradually decreases. As the slider d is moved to the right, the level of the tone signal of the tone generator 52 gradually increases, and the level of the tone signal of the tone generator 51 gradually decreases.

On the other hand, the ratio data of the three-dimensional table 53 is output non-linearly with respect to the input volume data. The tone signals of both systems as shown in FIG. This allows
When the position of the slider d is at the left end except for the vicinity of the center, the sound is generated by the automatic performance of the system I, and when the slider d is on the right side, the sound is generated by the automatic performance capable of giving the effect of the scratch record method of the system II. In the vicinity, the automatic performances of both systems are synthesized and sounded.

In the above embodiment, an example in which the present invention is applied to an automatic performance device and an electronic musical instrument has been described, but any type of electronic musical instrument may be used. Further, the present invention is not limited to the form of the electronic musical instrument, and may be applied to the input means as a form of a personal computer + application software.
