DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

[0001] The present invention relates to a tone control device for displacing a sound image position of a generated tone according to a gesture of a player.

[0002]

2. Description of the Related Art As is well known, in a natural musical instrument, it is common to play a string or a keyboard, or to blow a tube to form a musical tone, and most electronic musical instruments play a keyboard. This generates a musical tone. By the way, if it becomes possible to generate musical sounds based on natural human actions,
It becomes a performance operation that leaves the sense of playing with a conventional musical instrument, and a new performance pleasure and a new performance effect can be achieved. For example, a bending motion of a finger, a wrist, an elbow, a shoulder, or the like is a daily natural motion and is often used for choreography such as dance. Therefore, if the musical tone can be controlled based on these movements, it is possible to perform the musical tone control in accordance with this operation or a dance incorporating the bending movement.

[0003] From such a viewpoint, the present applicant has
Apart from the concept of "playing", a tone control device that controls a tone according to bending of a human hand or foot has been proposed. This type of device aims at performing musical tone control that matches the player's consciousness (emotion), particularly by associating the player's "movement" with the performance expression.

[0004]

In the above-described conventional tone control device, there are cases where the pitch and volume of the generated tone are controlled in accordance with the gesture of the player, or effect sound processing such as vibrato is performed. In many cases, generated musical tones generated in this way are generally emitted from a speaker as a stereo sound field via a mixer or the like. In such a case, since the sound image position of the stereo sound field is usually controlled by a person other than the player, the sound image position may not always be controlled as intended by the player. That is, if this control of the sound image position is regarded as one of the performance expressions, it is necessary to match this to the consciousness of the player, but the above-mentioned conventional sound control device cannot perform such sound image position control. There is a problem.
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a musical tone control device capable of changing a sound image position according to a gesture of a player.

[0005]

According to the present invention, there is provided a performance operator for generating performance information in accordance with a performance operation, a tone generator for generating a tone signal corresponding to the performance information, and generating the tone signal. A bend detecting means for detecting bending of the shoulder and generating a bending detection signal corresponding to the bending operation of the shoulder, and the musical tone forming means producing sound in accordance with the bending detection signal. Sound image position control means for controlling a sound image position of a musical sound.

[0006]

According to the above arrangement, the tone generating means generates a tone signal based on the performance information supplied from the performance operator, emits the tone signal, and the bending detecting means detects the bending of the player's shoulder. Generate a corresponding bending detection signal. Then, the sound image position control means controls the sound image position of the musical sound generated by the musical sound forming means according to the bending detection signal. As a result, the sound image position changes according to the gesture of the player.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. A. FIG. 1 is a block diagram showing a configuration of an embodiment according to the present invention. In this figure, reference numeral 1 denotes a performance operator which is held by both hands of the player. The performance operation element 1 includes a right hand grip 1R held by the player's right hand and a left hand grip 1L held by the left hand. As shown in FIG. 2, the right hand grip 1R generates desired performance information DpR by appropriately operating a push button switch provided for each finger of the player's right hand. The left hand grip 1L is also formed in the same manner, and generates performance information DpL. That is, the performance operator 1
Is a mode in which a keyboard or various operation switches of a normal electronic musical instrument can be held by a player's hand.
Here, the performance information Dp generated from the performance operator 1
R and DpL are information for designating the pitch, timbre, etc. of the generated musical tone.

Reference numeral 2 denotes a tone signal generating means comprising a CPU, a ROM, a RAM and the like.
A tone signal corresponding to R and DpL is generated. That is, the tone signal generating means 2 reads out from the waveform memory the waveform information of the timbre to be generated in accordance with the performance information DpR, DpL based on a well-known waveform memory reading method, and uses this as a tone signal of a predetermined pitch. Output.

Reference numerals 3a and 3b denote bending sensors mounted on the right and left shoulders of the player, respectively, for detecting bending of the joints of the shoulders. An example of the right shoulder bending sensor 3a will be described with reference to FIGS. In FIG. 3, reference numeral W denotes a wearer covering the upper body of the player, and a supporter B formed of an elastic material such as rubber is fitted on a shoulder joint covered by the wearer W. A resistor 12 of the angle detector 10 is mounted near the center of the supporter B.

A lever 13 is fixed to a shaft 12a of the resistor 12, and a tip of the lever 13 is inserted into and out of a cylinder 14 as shown in FIG. A spring 15 for retracting the lever 13 is provided inside the cylinder 14, and a fixing portion 14 a formed at the end of the cylinder 14 is attached to the mounting tool W. In such a configuration, when the player swings his arm, the lever 13 and the cylinder 14 rotate around the shaft 12a in accordance with this operation, and the resistance value of the resistor 12 changes according to this rotation. . in this way,
The bending sensors 3a and 3b generate detection signals SR and SL corresponding to the swing angles of the right arm and the left arm, respectively. That is, the signal levels of the detection signals SR and SL also increase as the arm swing angle increases.

Next, returning to FIG. 1, description of the configuration of the embodiment will be continued. Right shoulder bending sensor 3a having the above configuration
And the detection signals SR and SL output from the left shoulder bending sensor 3b are supplied to A / D converters 5a and 5b via amplifiers 4a and 4b. The A / D converters 5a and 5b convert the detection signals SR and SL described above into digital data, and output the data as data DR and DL, respectively.

Reference numeral 6 denotes a balance control means, which includes a ratio setting circuit 6a, a selector 6b, a difference circuit 6c, and a multiplication circuit 6.
d, 6e. This ratio setting circuit 6a
Outputs signals supplied to the input terminals A and B in a relation of A / A + B. The selector 6b selects and outputs the smaller one of the data DR and DL supplied to the terminals T1 and T2, respectively. The difference circuit 6c generates a signal having a relation of "1-A" obtained by subtracting the signal supplied to the input terminal A from the "1" signal set at the input terminal B.

The multiplier 6d multiplies the output of the ratio setting circuit 6a by the output of the selector 6b and outputs the result. On the other hand, the multiplier 6e multiplies the output of the difference circuit 6c by the output of the selector 6b and outputs the result. According to such a configuration, the control data BR and BL corresponding to the bending of the player's shoulder, that is, the swing-up angles of the right arm and the left arm, are each assigned to the multiplier 6.
d, 6e. The control data BR, BL
Are used for sound image position control described later. Note that the balance control means 6 having the above-described configuration can also be realized by calculation using software or using a data table (ROM) having two inputs and two outputs.

Reference numerals 7a and 7b are D / A converters. D / A
The converter 7a converts the control data BR into an analog signal and outputs this as a sound image position signal RB. Also,
The D / A converter 7b converts the control data BL into an analog signal and outputs this as a sound image position signal LB. SS
Is a sound system for amplifying a tone signal output from the tone signal generating means 2 and generating sound from a speaker. In this sound system SS, a right channel sound is generated by an amplifier AMP1 and a speaker SP1.
The left channel sound is generated by the MP2 and the speaker SP2 to form a stereo sound field. Here, the amplification factor of the amplifier AMP1 is controlled according to the above-described sound image position signal RB, while the amplification factor of the amplifier AMP2 is controlled according to the sound image position signal. That is, as the swing angle of the right arm and the left arm of the player increases, the amplifier A
The amplification factors of MP1 and AMP2 increase.

B. Operation of Embodiment Next, the operation of the embodiment with the above configuration will be described with reference to FIGS.
With reference to FIG. In the description of the operation,
It is assumed that the player performs in the style shown in FIG.
That is, the player wears the above-mentioned wearing tool W, and holds the grip 1R with the right hand and the grip 1L with the left hand. Further, it is assumed that the speakers SP1 and SP2 are respectively disposed on both sides of the player.

In this state, for example, as shown in FIG. 7A, if the player operates the performance operator 1 with both arms down, the above-mentioned sound image position signal R
Since B and LB are at the same level, the speakers SP1, S
The sound image position P of the tone signal generated from P2 is located in front of the player. It should be noted that the sound image position P shown in this figure represents not only the position of the sound image with respect to the player, but also the volume level of the generated musical sound.

Next, as shown in FIG. 7B, when the player swings only the left arm, the swing angle is detected by the left shoulder bending sensor 3b. As a result, a sound image position signal LB corresponding to the swing angle of the left arm is generated, and the amplification factor of the amplifier AMP2 increases according to the signal LB. As a result, the volume level of the speaker SP2 increases, so that the sound image position P moves to the left. Then, when the player further raises his left arm, the speaker SP2
Also increases, and the sound image position P also moves to the left. On the other hand, when the player swings his right arm up as shown in FIGS. 8A and 8B, the sound image position P sequentially moves to the right as in the case described above.

As shown in FIGS. 9 (a) and 9 (b), when the player swings both arms up at the same angle, the volume of sound emitted from the speakers SP1 and SP2 similarly increases. Is located in the center. However, in such a case, the speaker SP1 and the speaker SP
2, the sound field, that is, the area indicated by the sound image position P is expanded. Such a spread of the sound field can also be achieved by phase-modulating the tone signal.

Thus, in the embodiment described above,
Since the sound image position of the generated musical tone can be controlled according to the swinging state of the player's arm, the musical tone can be controlled more in accordance with the player's consciousness. In the above-described embodiment, the player holds the grips 1R and 1L with both hands. However, the present invention is not limited to this. For example, as shown in FIG. Wear W,
The sound image may be controlled according to the bending of the shoulder when operating a normal keyboard instrument.

[0020]

As described above, according to the present invention, the musical tone forming means generates a musical tone signal based on the performance information supplied from the performance operator, emits the musical tone signal, and the bending detecting means. A bending detection signal corresponding to the bending motion of the player's shoulder is generated. Then, since the sound image position control means controls the sound image position of the musical sound generated by the musical sound forming means in accordance with the bending detection signal, the sound image position can be changed according to the gesture of the player.
