Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument which exhibits a tone change similar to that of a natural musical instrument among electronic musical instruments.

2. Description of the Related Art In recent years, digital musical sound source synthesizing methods have been introduced into electronic musical instruments, and the quality of synthesized sounds has been remarkably improved. In addition, input methods have been diversified, such as keyboards, wind instruments, and guitars. ing. In these electronic musical instruments, in order to realize a response to a performance expression similar to that of a natural musical instrument, for example, a touch response function that changes a synthesized sound to be output in accordance with a tapping strength of a keyboard, or a two-function
A legato function has been proposed that changes the synthesized sound to be output when the input is continuous in time and when the input is not continuous. Such a function is described in, for example,
-209793 or JP-A-59-176784.

Hereinafter, an electronic musical instrument that realizes the above-described touch response function will be described with reference to the drawings.

FIG. 5 shows the configuration of a conventional electronic musical instrument. In FIG. 5, reference numeral 20 denotes a pitch instructing unit, 21 denotes a tone instructing unit, 24 denotes a tone synthesizing unit, 25 denotes a tone synthesizing unit, 26 denotes a tone synthesizing unit, 23 denotes a selector, 27 denotes a tone generating unit, and 40 denotes a touch detection. Department.

The operation of the electronic musical instrument configured as described above will be described below.

Each of the tone synthesizers 24, 25, and 26 constituting the tone generator 27 synthesizes and outputs a tone having a tone color corresponding to the strength of the touch, that is, the performance.

First, the pitch of the sound to be output is input to the pitch indicating section 20. It is assumed that the pitch indicating section 20 has an input form such as a keyboard, a wind instrument, or a guitar. The pitch instructing unit 20 determines the input mode of the pitch instruction according to the position of the depressed key in the case of a keyboard, the combination pattern of the depressed keys in the case of a wind instrument shape, and the case of a guitar shape. The pitch of the musical tone to be output (so-called pitch name) is determined according to the position (fret) where the string is pressed, and the pitch data is output to the musical tone generator 27. When the input form of the pitch indicating section 20 is, for example, a keyboard composed of 88 keys, the pitch data is sequentially inputted from a low-frequency keyboard.
The pitch data consisting of 7 bits is output as 1,2, ..., 86,87.

The sounding instructing unit 21 responds to key press and key release when the sounding instruction is input in the form of a keyboard, to start and stop expiration in the case of a wind instrument, and to strings in the case of a guitar. In response to the start and stop of the vibration of the tone generator, information on / off of a tone to be output, that is, information on start / stop of tone generation is output.

In the tone generator 27, the tone synthesizers 24, 25, and 26 generate pitch data according to the pitch data input from the pitch indicator 20 and the ON / OFF information input from the tone generator 21 and start sounding. , At the timing of the stop, a predetermined weak sound, medium sound,
Synthesizing and outputting musical tones of tones corresponding to strong sounds. Here, each tone synthesizer 24, 25, 26 can be composed of, for example, a waveform memory, an address generator, and a clock generator, and outputs a clock proportional to a pitch to be output from the clock generator, The tone waveform data stored in the waveform memory can be sequentially output by the address output of the address generator that is incremented by the timing corresponding to the clock.

On the other hand, the sounding instruction unit 21 measures the amount of touch input corresponding to various sounding instruction input forms in order to realize a touch response function, and outputs the measured value A to the touch detection unit 40. As the touch input amount, a key pressing speed in the case of a keyboard input, an expiration flow rate in the case of a wind instrument shape, a string vibration intensity in the case of a guitar shape, and the like can be used. The touch detection unit 40 determines the touch value Tv as shown in Table 1 by comparing the input measurement value A with predetermined touch determination values Tp and Tf, and outputs the touch value Tv to the selector 23.

The selector 23 corresponds to the input touch value Tv,
The outputs of the tone synthesizers 24, 25 and 26 are selectively output. That is,
When the touch value Tv is 1, the tone synthesis unit 24 that outputs a tone corresponding to a weak tone is selected. When the touch value Tv is 2, a tone corresponding to a middle tone (from mezzo piano to meso forte) is selected. When the tone synthesis unit 25 to be output is selected and the touch value Tv is 3, the tone synthesis unit 26 that outputs a tone having a tone color corresponding to a strong tone is selected and output.

As described above, it is possible to obtain a musical tone having a tone corresponding to the touch expression input.

In an electronic musical instrument having a legato function, it is detected whether the two inputs to the sounding instruction section 21 are temporally continuous (legato) or not (non-legato), and the selector 23 determines whether the two inputs to the legato function are in accordance with the result. Alternatively, the legato function is realized by selecting a tone synthesizer that outputs a tone of a tone color at the time of non-legato.

However, in the above-described configuration, the response to a performance expression such as a general characteristic of a natural musical instrument, that is, a timbre changes according to the strength of a touch or a timbre changes according to a legato playing technique. A characteristic can be given to an electronic musical instrument, but when there are a plurality of performance modes for playing a sound having the same pitch (the same pitch), such as using different fingers in a wind instrument or using different strings in a stringed instrument. However, there is also a problem that it is impossible to output a tone corresponding to each of a plurality of performance modes.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides an electronic musical instrument capable of realizing a timbre change corresponding to a playing form when there are a plurality of playing forms for playing sounds having the same note name. .

Means for Solving the Problems In order to achieve this object, an electronic musical instrument according to the present invention includes a pitch indicating section having an input form similar to that of a wind instrument, and a plurality of replacement fingers capable of indicating the same pitch unique to the wind instrument. A tone control unit for selecting and instructing a tone to be output in accordance with a playing mode corresponding to the input mode from a playing mode of the above, a sounding instructing unit for instructing a sounding timing, and a plurality of replacement fingers capable of indicating the same pitch. A tone generator that can generate different timbres for each form and generates the timbre specified by the timbre controller at the sounding timing.

Operation With this configuration, the tone generator generates the tone of the tone determined by the tone selection data output from the tone controller from among a plurality of tones corresponding to the same pitch that differ depending on the performance style specific to the wind instrument. The pitch is in accordance with the pitch data output from the instruction unit, and is output according to the sounding timing output from the sounding instruction unit.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an electronic musical instrument according to a first embodiment of the present invention. In the first embodiment, the same replacement finger or string as that of a natural musical instrument can be used in the input form itself. It is an object of the present invention to realize a tone change similar to a natural musical instrument in an electronic musical instrument.

In FIG. 1, reference numeral 10 denotes a pitch indicating section for inputting a pitch;
Is a tone control unit that outputs tone selection data of a tone to be output, 14 to 16 are tone synthesis units that generate tones of different tones depending on the performance form such as a replacement finger or a replacement string, and 17 is a tone synthesis unit 14 to 16 And a selector for selecting a tone output from the tone synthesizers 14 to 16 based on the tone color selection data. A tone generation unit 21 for instructing a tone generation timing is provided.

When the type of the musical tone to be output is a guitar, the musical tone synthesizing units 14, 15, and 16 constituting the musical tone generating unit 17 are, for example,
The tone when the first string (highest string) of a six-string guitar is played with an open string, the tone when the second string is pressed with the fifth fret pressed, and the tone when the third string is pressed with the ninth fret Tones are output when played. That is, these timbres are sounds of a guitar having the same pitch, but have completely different timbres.

Also, when the type of musical sound to be output is a wind instrument,
The musical sound synthesizing units 14 and 15 constituting the musical sound generating unit 17 include, for example,
Regarding the sound of "do", which is called by the floor name, the tone of "do" of opening the tube by fingering when the finger is almost released, and the sound of "do" of closing the tube by fingering when the finger is almost pressed down Make a composite output. That is, even though most wind instruments have different note names (absolute note names), the "do" sound, which is called by the so-called floor name, is played by fingering close to the open pipe and close to the close pipe as described above. There is a performance form by fingering, and these timbres are sounds of wind instruments having the same pitch, but the timbres are completely different.

In order to make it easy to understand what kind of form the performance means, the above-mentioned "replacement string" and "replacement finger" are explained. It is not a dynamic input like a touch response, but a static input form, such as a different tone even if the same position is pressed due to the difference between pressing firmly or loosely. Means.

First, the pitch of the sound to be output is input to the pitch indicating section 10. The pitch instructing section 10 uses a combination of pressed keys when the input form of the pitch instruction is a wind instrument shape, and a position where the strings are pressed (fret) when the input form is a guitar shape. Then, the pitch of the musical tone to be output (so-called pitch name) is determined, and the pitch data is output to the musical tone generator 17.

In the present embodiment, an electronic musical instrument having a wind instrument shape input form will be described.

It is assumed that the pitch indicating section 10 has a wind instrument-like input form according to fingering as shown in Table 2. The pitch indicating section 10 includes a switch group Si arranged in a wind instrument shape as shown in FIG.
(I = 1,2, ..., 8) input pattern (pattern of fingering table)
The pitch codes described in Table 2 are determined in accordance with the above, and the pitch codes are output to the musical tone generator 17. Where each switch
Si can be configured as shown in FIG.
In FIG. 3, 101 is a push button, 102 and 103 are push button return springs, and 104 and 105 are casings of a wind instrument type main body. The output of each switch Si is OFF when the push button 101 is pressed and ON when the push button 101 is not pressed. In Table 2, the OFF and ON are indicated by ● and ○, respectively. On the other hand, the pitch indicating section 10 includes a switch group Si
The input pattern (i = 1, 2,..., 8) is output to the tone color control unit 12. The timbre control unit 12 receives the input switch group Si (i =
The tone selection codes described in Table 3 are determined according to the input patterns (1, 2,..., 8), and the tone selection codes are assigned to the tone generator.
Output to 17. As in the prior art, the tone generator 17 selects the output of the desired tone synthesizer by the selector 23 in accordance with the output tone color selection data, and the tone is output.

Therefore, when the form No. 8 is inputted, the pitch indicating section 10
Detects the pitch code 8 and outputs it to the tone generator 17 as pitch instruction data, and outputs the form No. 8 to the tone controller 12. The timbre control unit 12 controls the selector 23 so as to selectively output the output of the tone synthesis unit 14 that outputs the timbre corresponding to the timbre selection data 1 of form No. 8. When the mode No. is 9, the tone color control unit 12 controls the selector 23 so that the output of the tone synthesis unit 15 that outputs the tone color corresponding to the tone color selection data 2 is selected.

When the start of sounding is instructed to the sounding instructing section 21, the tone and the tone having the pitch determined as described above are output in the same manner as in the conventional example.

Similarly, in the case of the input form in the form of a guitar, for example, the tone synthesizers 14, 15 and 16 respectively output the tone having the same pitch that can be output by the first string, the second string and the third string. It is possible to selectively output a characteristic timbre for each string by using different timbres.

In the above, the tone synthesis unit selected by the tone color selection data is within one octave or one string.
Although the timbre is shared in the pitch direction, the timbre can be further subdivided in the pitch direction, and the touch response function can be further added to the timbre corresponding to the replacement finger as in the conventional example. It is also possible to add.

It should be noted that a so-called sound source module is constituted by only the tone control section and the tone generation section of the electronic musical instrument shown in the present embodiment, and the tone control section inputs data designating a type of a different musical instrument as a form No. to select a tone. By determining the data as described above, It is also possible to select the timbre of the tone output from the tone generator. The sound source module referred to here is, for example, MIDI (Musical Instrument Digital Int.)
device that receives information of a musical tone to be output through communication such as erface) and generates a musical tone in accordance with the received musical tone information.

As described above, according to the first embodiment, when a replacement finger or a replacement string similar to the natural musical instrument is input to the pitch indicating section having the same input form as the natural musical instrument, the timbre control is performed. Unit determines the timbre to be output according to the input form, and the tone of the determined timbre is selectively output from the tone generation unit. Can be realized.

Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

In the second embodiment, it is an object of the present invention to realize a tone change similar to that of a natural musical instrument even in an electronic musical instrument in which it is difficult to properly use a replacement finger or a replacement string in the input form itself.

FIG. 4 is a block diagram showing an electronic musical instrument according to a second embodiment of the present invention.

In FIG. 4, reference numeral 30 denotes a pitch indicating unit for indicating a pitch;
Is a form designating unit for designating a form described in detail later.

Reference numeral 12 denotes a tone control section, 14 denotes a tone synthesis section, 15 denotes a tone synthesis section, 16 denotes a tone synthesis section, 17 denotes a tone generation section, 21 denotes a tone generation instruction section, and 23 denotes a selector. It is the same as the example.

In this embodiment, the types of musical sounds output by the musical sound synthesizing units 14 and 15 are the sounds of a wind instrument (vertical flute) as in the first embodiment.

The pitch indicating section 30 has a keyboard-like input form. In other words, it is assumed that the input form does not allow the instruction input of the same pitch different tone color, such as a so-called extra finger or extra string. The form instructing unit 31 instructs the pitch instructing unit 30 of a form No. to be properly used depending on the input form. That is, among the multiple form numbers that exist for the same note name, which form N
When a morphological instruction input for determining whether o has been input is made, the morphological instruction unit 31 transmits the morphological instruction data to the pitch instruction unit 30.
Output to

A case in which the type of musical tone that outputs this operation is the wind instrument described in the first embodiment will be described. When the sound to be output is form No. 8 or 9, the form instructing section 31 is instructed to type 1 or type 2, respectively. When the input is of type 1, the form instruction unit 31
SLCT = 1 is output, and when the input is type 2, the configuration instruction data SLCT = 2 is output. The pitch instructing unit 30 determines the pitch according to the position of the input keyboard in the same manner as in the conventional example, and outputs the pitch data to the musical tone generating unit 17. Further, the pitch instructing section 30 determines the form No. from the inputted form indicating data SLCT and the pitch data in accordance with Table 4, and outputs the form No. to the tone color control section 12. Thereafter, in the same manner as in the first embodiment, a musical tone of a desired tone is output.

Although the above description has been given of the musical tones of wind instruments, it goes without saying that, for example, with respect to the musical tones of a guitar, there are not only two types to be input to the form instruction unit, but also more types. In the present embodiment, the configuration instruction unit is configured to input to the pitch instruction unit, but the output of the pitch instruction unit and the output of the configuration instruction unit are input to the timbre control unit, and the timbre control unit It is also possible to configure so that the form number is determined.

As described above, according to the present embodiment, the output should be performed in accordance with the input form determined by the form indicating unit for inputting the use instruction input such as the replacement finger or the replacement string similar to the natural musical instrument, and the pitch indicating unit. The timbre control unit determines the timbre, and the tone of the determined timbre is selected and output from the tone generation unit. Instead, it is possible to selectively use the tone color of the musical tone to be output while indicating the preferred tone color during performance.

Advantageous Effects of the Invention The present invention can use tone sounds of the same pitch and different timbres, which are generated by a replacement finger or a replacement string unique to a natural musical instrument, in accordance with an input, thereby realizing the same timbre change as a natural musical instrument. it can.
