Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter control device for an electronic performance device, in which various parameters for controlling a musical sound generated by a performance operation are changed by a rotating operation or a pressing operation.

[0002]

2. Description of the Related Art Generally, musical tone parameter control devices for electronic musical instruments other than a keyboard include a wheel type, a joystick type, a surface control type, a jog dial type, a pad type, and the like. Select and place. Since the present invention relates to the last two types, these prior arts will be described. The jog dial type operator is, for example, as shown in Japanese Utility Model Laid-Open No. 7-8928, parameter control is performed by rotating a disk type operator placed parallel to the panel surface. The child is, for example, JP-A-6-22277.
As shown in FIG. 5, when the striking surface is hit, the vibration sensor attached to the back surface senses the vibration.
In addition, multidimensional input devices having other configurations can also be found, and there are functionally ones in which a "turn" operation and a "push" operation can be performed with a single operator. This conventional technology also
The present invention can also be said to be one of the multidimensional input devices, and its major object is to expand the musical expression.

[0003]

However, each of them has a problem that not only the structure thereof is too complicated and the cost becomes high, but also the distance from the upper surface of the knob to the lower surface of the sensor is long and it cannot be made thin. was there. Also, the pad operator produces a musical sound when hitting the pad,
If the sustain part (sustaining part) is a long musical tone, there is a problem that short notes on the score cannot be faithfully expressed. The mute when a long sound is generated in another field, for example, the attenuation musical tone of the electronic keyboard instrument, can be performed by the rapid attenuation process at the time of the key release operation and the key release operation of the damper pedal, but this cannot be directly adopted as the pad operator. Because the pad-type controller is like a percussion instrument, the action and the image are reversed. In other words, if you hit a percussion instrument such as an acoustic cymbal with a stick and press it as it is,
Musical sounds are attenuated immediately, so the basic operation is to release them immediately after hitting them. Therefore, in order to enable the operation of short notes of long tones, add some other operation, and
There was a problem that the other operation had to be easily realized.

Therefore, the present invention has been made to solve the above problems, and it is a common object (first object) of all the claimed inventions to expand the musical expression, and further claims. In the inventions 1 and 2, the object is to have a simple structure and to be thin (second object), and in the invention of claim 3, it is easy to mute the musical sound generated by the pressing operation of the pad type operator. The purpose of doing so (3rd

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows the operating device of the present invention in a body B.
An overall plan view of a guitar-like electronic musical instrument arranged in D,
2 is a detailed view of the manipulator device, which is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a detailed plan view of the device.
As shown in Fig. 1, it looks like a guitar as a whole, but it should be functionally called a performance assisting device or a performance participating device. is there.

The outline of this playing device will be described first. Memory pack 10 with built-in music data consisting of multiple parts
Is inserted into the terminal 11 of the torso BD, and the start / stop switch 12 is pressed to start the song. If you select a part with the part switch 14 before starting, that part will be given a minus one, and the player will be responsible for that part, but in a certain mode, all the parts will be given a minus one. Instead, for example, when the player takes charge of the accompaniment, only the chord constituent sounds are assigned to the switch sections 61 to 6n of the switch operation section 6s. Whenever this switch is pressed, or the music progresses automatically, the performance proceeds. At this time, the pad type operator (which is also a rotary operation unit, hereinafter referred to as a pad) 7
You can also decide the pronunciation timing. Switch 61
6n and the pad 7 participate in the performance, the musical tones assigned to the switches 61 to 6n are ambiguous in that they are any of the above chord constituting tones, melody tones, percussion tones, or a combination thereof.

Further, as a mode of participation in the performance, a new musical instrument sound can be added by the switches 61 to 6n and the pad 7 while making the performance automatic. That is, it is assumed that an instrument sound (timbre) other than the automatic performance is selected and one or more of the switches 61 to 6n are pressed (addition operation of the pad 7 is arbitrary).
Even if it is random (however, it is desirable to match the timing with the rhythm), but if it is a chord constituent sound, there is no discomfort as the song progresses. This is because each time the additional chord is changed, it is assigned in response to the progress of the piece of music, so that the piece of music to which the ad lib is added is arranged into a novel piece.

Such a musical performance apparatus is roughly a neck N.
And body BD, which are upper case 1 and lower case 3
It is constructed as one piece with bivalves. Details of the pad type manipulator device according to the present invention are shown in FIGS. The pad 7 serves as a rotary operation unit (rotary knob), and outputs data corresponding to the rotary operation and the pressing operation, or both, from each sensor. Support member 72
The holding portions 31 and 32 provided in the lower case 3 are disposed via the.

This will be described in detail. The base end portion 721 of the rotation sensor support member 72 is fixed to the holding portions 31 and 32, which are integrally formed from the lower case 3 and are formed of boss-like protrusions, with screws 33. The holding portion 32 is composed of two independent bosses,
It is longer than the holding portion 31. One of the rotation sensor support portions 722 having both bent portions B1 is connected from the base end portion 721 via the rotation axis J, and the other is connected to the holding portion 31 composed of two independent bosses via the annular elastic member 311. It is elastically fixed by a screw 34. The other end has a bent portion B2 bent downward and narrower than the support portion 722, and the end surface of the bent portion is covered with an elastic sheet st made of rubber or the like. An after sensor (pressing force detection sensor) AT mounting table 35 is formed integrally with the lower case 3 at a position where it comes into contact with the lower surface of the sheet.
The after sensor AT is mounted on this upper surface. The after sensor AT is composed of two upper and lower sheets, and has a sensor pattern formed on its facing contact surface by a semiconductive layered body made of a paste-like substance of carbon and insulating powder. The upper and lower sheets may be one folded sheet.

A through hole o1 is opened substantially at the center of the support member 72, and a rotation sensor 71 for generating a signal corresponding to rotation is fixed through the through hole o1. The diameter of the rotating shaft 711 is smaller than the through hole o1 and is rotatable. This rotating shaft 7
A rotary knob (pad) 7 is fixed to 11. The center portion c1 of the coil spring c is fitted into the outer end of the shaft corresponding portion of the knob 7 and both ends cf1 and cf2 of the spring are
Spring end driving projection ac hanging from knob 7 and supporting portion 7
The spring end stopper piece sp hanging down from 22 is supported. The upper case 1 is provided with a through hole h through which the knob 7 can rotate, and a knob 7 having a diameter larger than the through hole h is provided. The knob 7 includes a lower body 7b and an upper cover 7a.
And four annular touch sensors TS are provided between them (see FIG. 2). The lower main body 7b and the upper cover 7a are screwed from below through the annular central hole with screws 74, 75, 76, 77.
Will be landed. This touch sensor TS is similar in principle to the above-described after sensor, and generates an analog output with a variable resistance value (a digital value may be directly generated) depending on the degree of pressing force. A conductive elastic body may be interposed between the contact surfaces of the sensor patterns as a cushioning material and a differential coefficient easing member. The sensor output lead wire 1 is wired from the hole o2 opened in the lower main body 7b of the knob 7, and the reinforcing ribs R are provided on the holding portions 31 and 32. Further, as shown by a dotted line in FIG. 2, a single piezoelectric sensor p made of a piezo element may be attached to the lower surface of the upper cover 7a.

FIG. 4 shows a musical tone generating system for the entire playing apparatus. The fret switch 6 includes switch portions 61, 62, ..., 6n arranged in the operation portion 6s of FIG.
Represents a switch group consisting of, and these outputs are supplied to the automatic performance data forming means acc. The automatic performance data forming means acc also has an automatic accompaniment function. The pitch of a specific part of the accompaniment pattern in the music data, for example, the part of the bass guitar, is designated by the switch operation information corresponding to the operation of one or more of the switch parts. It should be noted here that the optimum chord (chord) of the bar or phrase currently playing is not associated with the designation method that is simply assigned such that 61 is C and 62 is C #. The constituent tones (for example, 61 is C, 62 is E, next is G, next is C one octave above, and next is G, ...) Modes in the control means 80 including other control switch groups. It is assigned to the fret switch when the predetermined mode is selected by the designated switch. When the fret switch 6 is appropriately operated in accordance with the timing of the musical sound of the other part, the designated chord component sound designates the sound source TG together with the musical sound of the other part, so that the musical tone is formed by the sound source TG. , A sound system SS including an amplifier AMP and a speaker SP generates those musical sounds.

In this case, the designated timing signal is formed based on the outputs from the touch sensors TS1 to TS4.
That is, when the knob 7 is pressed, the touch sensors TS1 to TS1.
A voltage is generated from TS4. This voltage outputs a resistance change from the sensor, so if a voltage is applied to it,
It can be extracted as a voltage change and this voltage change is used. Then, the voltages from the sensors TS1 to TS2 are converted into digital values by the AD converters A / D1 to 4, respectively, and sifted by a threshold detector Thr81 that outputs a predetermined value or more, and each of the outputs is one of them. If there is an output even a little, those ORs are taken by the OR circuit OR, and the output is passed through the one-shot circuit OS composed of a retriggerable monostable multivibrator which can be retriggered, and the output is a designated signal for stepping. And This signal drives a sequence for music progression. The stepping designation signal may be a single designation signal from the sensor P shown by the dotted line in FIG. 2, or may be a simple switch. In FIG. 4, the reason why the plurality of touch sensors are used and the level sensor is used is to enhance the performance expressing power of the touch sensor, and to reflect the information on the touch position of the knob 7 and its strength on the performance expressing power. is there.

That is, the four touch sensors TS1 to TS
As can be seen in FIG. 3, since the parts 4 are arranged so as to be scattered approximately evenly on the knobs 7, for example, TS1 and TS
When a force is applied between 2 and a certain pressing force, stronger outputs from TS1 and TS2 and weaker outputs from TS3 and TS4 are input to the inputs i1 to i4 of the maximum output passage means 83. Each line is a line composed of a plurality of bits, and in the means 83, only the one having the largest value among i1 to i4 is input to the sound source TG as the level signal LE, and the means 83 outputs the level data. Is i1 to i4
A kind signal k is output, and the kind signal k
Is output for the B input of the selector 85. i1-i
If any two of 4 have the same value, the priority circuit is called the one with the smaller number, and if all four have the same value, that is, the condition is satisfied is that the center is hit. However, under that condition, the condition fulfillment signal "1" that clears the condition that the absolute value of (maximum value-minimum value) is smaller than the predetermined value is detected by the detection means 87 to which all i1 to i4 are input. Select instruction terminal SA of the selector 85
Lead to. When this condition is satisfied, the type data “111” meaning the center of the knob 7 is selected by the selector 85, otherwise, the type data meaning any one of TS1 to TS4 is selected and the type signal K is output, It is input to the sound source TG together with the level data at that time. By this means a
The sound source designated by c is tone-processed by the sound source TG with LE and K and output from the sound system SS.

The following is given as an example of the designation information of LE and K. (1) Use K to select an automatic performance part, and use LE to control the cutoff frequencies of the various tone color filters. (2) A tone system to be generated at a predetermined timing (piano system, wind instrument system, string instrument system, percussion instrument system) is selected, and the tone color of the tone is cutoff frequency controlled as in the above (1). In this case, if there is no tone selected by the touch sensor in the tone to be generated at this timing, the tone is ignored. (3) Ignore the level signal, or touch sensor T
S1 to TS4 may be composed of simple switches, and the tone color may be controlled only by the type signal K. In this case, the filter cutoff frequencies for tone color control are preset to four predetermined frequencies. (4) One touch sensor may be provided as shown by the dotted line in FIG. 2, and only the level signal may be used to control the timbre by the touch strength.

The signal from the rotation sensor 71 is composed of a rotary encoder or an analog volume, and the information is generated by using any one or a plurality of values of the rotation amount, the position, and the change amount of this sensor. Have been sent to. As a result, the pitch control of the designated sound source from the means acc is performed in response to this signal. In other words, this gives you vibrato control or something like a pitch bender.

Further, vol is a volume control system, which is operated by pressing the mute operator mt shown in FIG.
The mute switch 24 is turned on to generate the select signal SB = "1" of the selector 90, and at this time, the minus B from the register 91 is output from the selector 90.
If the mute switch 24 is not pressed, zero is output from the register 92. The output of the selector 90 is subtracted by the adder 94 (the output value of the after sensor minus a predetermined value B) together with the output of the after sensor AT.
, A predetermined value from the register 95 is added, and this value is converted into an analog signal by the DA converter 97 to control the amplification value of the amplifier AMP. When the mute switch 24 is turned on with this configuration, the musical tone currently being generated can be muted (attenuated) by a value corresponding to B.

In particular, when the fret switch 6 is assigned to a percussion instrument sound source (for example, a tom tom or bongo scale) or an attenuation system sound source such as a guitar, the effect is fully exhibited. In other words, if you want to control the sound source of an attenuation system (system that attenuates while continuing) represented by short notes on the score, or want to consciously mute at a given arbitrary timing when expressing a sound with ending or fermata . It is convenient in such a case. Moreover, since this mute operator is arranged near the rear of the pad operator, it can be made similar to the case where the string vibration of the guitar is stopped at the base of the hand, and it can be performed naturally. There is an advantage (effect of the invention according to claim 3). In the embodiment of the present invention, since the sounding instruction is given by the touch sensor provided on the rotary knob itself, the sensitivity for generating the sounding instruction signal is high and the delay is small (the response is good). Further, since the touch sensor output is separately output as the intensity data and the position output, the control target can be matched in various ways such as tone color and effect.

[0020]

As described above, according to the present invention, it is possible to provide a performance operation operator device which has improved performance expression and good operability. In addition, in the invention according to claim 1, by arranging the after-touch pressure sensor around the rotation sensor, not directly under the rotation sensor, it is possible to reduce the thickness of the entire device, and to reduce the number of types of sensors. The stability during operation is also improved. In the invention according to claim 2, the operability of all the sensors is improved. Further, in the third aspect of the invention, since the mute operation can be performed by an operation similar to the existing mute operation (string stopping operation) of a guitar or the like, there is no discomfort in operation and the operability is improved.
