Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operator device for performance operation of a standing electronic musical instrument.

[0002]

2. Description of the Related Art Generally, there are wheel type, joystick type, surface operator type, jog dial type, pad type, etc. as tone parameter control devices for electronic musical instruments excluding keyboards, and the features determined by each configuration are utilized. Selectively placed. Here, the jog dial type operator is, for example, as shown in Japanese Utility Model Laid-Open No. 7-8928, by rotating a disk type operator placed parallel to the panel surface, parameter control is performed. In the pad type operator, for example, as seen in JP-A-6-222775, when a striking surface is hit, a 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.

Further, the pad operator produces a musical tone when hitting the pad, but if the musical tone is long in the sustain portion (sustaining portion), there is a problem that short notes on the score cannot be faithfully expressed. . In other fields, for example, muffling when a long sound is generated in a decaying system musical tone of an electronic keyboard instrument can be performed by a rapid damping process at the time of key releasing operation and a key releasing operation of a damper pedal.
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, for example, if a percussion instrument such as an acoustic cymbal is hit with a stick and pressed as it is, the musical sound is immediately attenuated. Therefore, there is a problem in that some kind of additional operation must be added to enable the operation of short notes of a musical sound having a long continuous sound, and the operation must be easily realized.

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.
FIG. 2 is a detailed plan view of the guitar-like electronic musical instrument arranged in D, and FIG.
-A sectional drawing and Drawing 3 are detailed top views of the device. Figure 1
As shown in FIG. 2, it has a guitar-like appearance as a whole, but in terms of function, it should be called a performance assisting device or a performance participating device, and is a performance device that is responsible for a part of automatic performance.

The outline of this playing device will be described first. Memory pack 10 with built-in song data consisting of multiple parts
Insert the terminal 11 of the body BD and press the start / stop switch 12 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 formed of two independent bosses via the annular elastic member 311. It is elastically fixed by the screw 34. The other tip has a bent portion B2 that is bent downward and is narrower than the support portion 722, and the end surface of this bent portion is wrapped with an elastic sheet st 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 upper and lower two sheets, and has a sensor pattern formed on a facing contact surface thereof with a layered body of a semiconductive body made of a paste-like substance of carbon and insulating powder. The upper and lower sheets may be a single 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 rotary shaft 711 is smaller than that of the through hole o1 and is rotatable. This rotating shaft 7
A rotary knob (pad) 7 is fixedly attached to 11. A central portion c1 of the coil spring c is fitted and inserted into an outer tip outer contour of an axis-corresponding portion of the knob 7, and both ends cf1 and cf2 of the spring are
Spring-end driving protrusion ac hanging from the knob 7 and the support portion 7
The spring end stopper piece sp hanging 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, in principle, the same as the above-mentioned after sensor, and generates an analog output whose resistance value is variable depending on the degree of pressing force (it may directly generate a digital value). 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 of the entire musical instrument. The fret switch 6 includes switch portions 61, 62, ..., 6n arranged in the operation portion 6s of FIG.
Represents a group of switches, and their 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. What I want to note here is
61 is C, 62 is C #, not simply assigned, but corresponding to the progression of the song, the constituent chord of the optimum chord in the bar or phrase being played (for example, 61 is C , 62 is E, the next is G, the next is C, which is one octave higher, and the next is G, ...) Is selected to the predetermined mode by the mode designating switch in the control means 80 including other control switch groups. Sometimes assigned to fret switches. 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 are sifted by a threshold detector Thr81 that outputs a predetermined value or more. 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 consisting of the 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 expression performance of the touch sensor, and to reflect the information on the touch position of the knob 7 and its strength in the performance expression 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 multiple bits,
In the means 83, only the one having the largest value among i1 to i4 is used as the level signal LE for the level data LE of the sound source TG.
And the type signal k of any one of i1 to i4 is output from the means 83, and the type signal k is output for the B input of the selector 85. If any two of i1 to i4 have the same value, it is output by a priority circuit such as the one with the smaller number, and if all four have the same value, that is, the condition is satisfied at the center. However, under the 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 by the detection means 87 to which all of i1 to i4 are input. "To the select instruction terminal SA of the selector 85. When this condition is satisfied, the type data “111” that means the center of the knob 7 is selected by the selector 85, and otherwise,
The type data indicating any one of TS1 to TS4 is selected, the type signal K is output, and the type data is input to the sound source TG together with the level data at that time. As a result, the sound source designated by the means acc 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 among the tones generated at this timing, it 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,
The information is sent to the sound source by using one or more of the values of the rotation amount, position, and variation amount of the sensor. 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 together with the output of the after sensor AT (minus the predetermined value B from the output value of the after sensor), and the adder 96 is added.
Then, the 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. With this configuration, if the mute switch 24 is turned on, the musical tone currently 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, bongo scale) or an attenuation sound source such as a guitar, its effect is fully exhibited. In other words, when controlling a sound source of a decay system (a system that decays while continuing) represented by short notes on a score, or when expressing a sound with an ending or fermata, you want to intentionally mute at a predetermined timing. . This 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 can be performed naturally. There are advantages. 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 into the intensity data and the position output, it is possible to match the control object in various senses such as timbre and effect.

Lastly, the embodiments of the present invention will be described in detail by additionally describing the technique related to the performance control device of the standing electronic musical instrument of the present invention and its operation and effect.

The touch sensor TS is preferably used for instructing sounding (timing), but sounding may be instructed by a signal corresponding to a pressing force equal to or higher than a threshold value of the pressing force detection sensor AT. It is possible to provide a performance operating device having improved performance expression and good operability. In addition, the operability of all sensors is improved.
