Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a pitch control device for an electronic musical instrument, and more particularly to a technique for controlling portamento for a musical sound generated by a sound source.

[Prior Art and Its Problems] A set of operators (performance control input device) provided in an electronic musical instrument basically has a meaning as an operator for "playing" one "musical instrument". Therefore, in an electronic musical instrument equipped with a sound source having a plurality of musical tone generation channels, an arbitrary musical tone message given from the performance control input device (the instrument main body or an external performance control input device such as a MIDI controller) is given. A control device (typically a microcomputer) of an electronic musical instrument has performed control to find an empty tone generation channel and instruct the tone generation channel to generate sound. In the case of a synthetic type sound source, each tone generation channel is
By replacing the tone color data (including data such as a tone synthesis algorithm that variably defines the connection structure between modules when a plurality of waveform generation modules configure one tone generation channel),
It is possible to generate a musical tone of an arbitrary tone color within the range of the musical tone generating ability of the sound source. However, once the specific tone color data is set, only the tone of the tone color specified by the set tone color data can be generated (in the case of a sound source that performs complicated synthesis, the amount of tone color data is large,
The setting of the tone color data from the microcomputer to the tone generation channel is performed in advance because of the need for a real-time response to a sounding request, and is typically performed in response to the tone color selection operation on the instrument panel. In the case of a sound source that has a small amount of tone color data to be set, such as a sound source that uses PCM data, it is possible to transfer the tone color data to the sound source when instructing pronunciation).

The method of sounding one tone generation channel for one sounding message is in line with the basic idea that the performance control device, which is the source of the sounding message, is used as a performance operator of one musical instrument. . However, in this method, once the tone color data is set, the tone color of the tone generated in the tone generation channel is fixed, and the tone color does not change due to the tone generation message itself. For traditional instruments,
The timbre of the musical tone depends on the strength of the playing touch and the pitch.
Therefore, even in the electronic musical instrument, it is desirable that the timbre or the like changes depending on the information included in the pronunciation message. Certainly, a certain amount of change can be added to the musical sound (musical sound generating channel output) by controlling the envelope, the cutoff frequency, etc. in one musical sound generating channel depending on the sounding message. However, there is a limit to the degree of change. In order to add more dynamic changes, it is necessary to remove the limitation of one tone generation channel (tone color) for one phonetic message. In addition, it is grateful for a music expressor (performer) to be able to obtain the effect of playing multiple "instruments" at the same time (this is difficult for traditional acoustic instruments). Continued).

From the standpoint of pursuing the dynamism and realism of musical tone characteristics and the pursuit of musical performance expression by multiple musical instruments, recently, in addition to a mode in which one tone generation channel for one tone color is sounded, For tone generation messages, multiple different tone generation channels (with different tone colors and pitches) are played, or different tone generation channels are selected so that the tone color dynamically changes depending on the information contained in the tone generation message. Or a different tone generation channel can be played while changing the volume balance (tone mixing ratio) of different tone generation channels depending on the sounding message (called a combination mode). Has been put into practical use. It was. The combination mode includes, for example, a key split for switching the system (tone) depending on the range (key range), and two or more systems (including the same tone but different pitches or different sounding timings) depending on the range. Positional crossfade, which continuously changes the mixing ratio of musical tones, and velocity split, which switches the musical tone system according to the strength of the playing touch, are known.

By giving the electronic musical instrument the function of the combination mode, the performance expression, the realism of the musical sound, and the dynamism have been dramatically improved. Since the functions of the combination mode are fully exerted, in the combination mode, it is possible to set effect parameters for each of a plurality of different musical tone systems that can be generated, system by system.

For example, for pitch bend data (data for applying pitch bend to a musical tone), which is an effect parameter related to the present invention, an electronic musical instrument has been provided which can set independent pitch bend data for each musical tone system. As a result, it has become possible to create a very dynamic performance expression, in which different pitch bends are added depending on the system of the musical sound being played at the time of performance.However, this extreme pitch bend dynamism is due to the pitch bend operation data in the performance control input device. Occurrence or detection (depending on the type of operator used, how the operator is operated, etc.), the music to be played, or part of it It has a contradictory relationship, and it is often inconvenient for the musician, the performer.

For example, in the case of an electronic keyboard instrument, the manipulator that specifies a scale sound and the manipulator that specifies a pitch deviation from the scale sound are separate and independent. Of course, the scale operator is a keyboard,
An operator for pitch deviation (pitch bend) is an operator (bender wheel) provided on the left side of the keyboard or the like, typically in the form of a wheel. A typical bender wheel has no pitch bend information when no operation is performed (for example, the entire range of pitch bend operation data is 0 to 12).
Signals corresponding to 64 values if assigned to 7)
Is output. If you turn the wheel about 90 ° to the front, it will be full, and it will not rotate any further. At this time, the bender wheel outputs the maximum downbend information (a signal corresponding to a value of 0 in the above example). On the contrary, even if it is turned about 90 °, the wheel hits the stopper and does not rotate any further. At this time, the wheel outputs maximum upbend information (a signal corresponding to the value of 127). On the other hand, the pitch bend setting data set when setting the pitch bend is generally the width of the pitch bend (bend range). Therefore, the pitch bend of the set bend range (up or down depending on the rotation direction) is applied at the position where the bender wheel is rotated to the maximum, and the set bend range data is calculated as sensitivity data at the intermediate position. Pitch deviation occurs. In the pitch bend performance, the player basically considers the size of the pitch bend, and in this sense, the structure in which the wheel rotates only within a certain range facilitates the pitch bend control of the player. Also, in the case of an electronic keyboard instrument, the bender wheel is separate from the keyboard, which is the operator of the scale notes, so many players only occasionally operate the bender wheel to give a special effect. Therefore, under the above-mentioned environment, different bend range data is set for each tone system in the combination mode, and pitch bend operation is performed during performance in the combination mode, so that each tone system is different. The ability to have a pitch bend is significant.

However, there are completely other environments than those mentioned above. For example, in the case of an electronic stringed instrument such as an electronic guitar, in this case, the manipulator for designating a scale note and the manipulator for designating a pitch bend are the same. That is, the "string" is an operator common to both. In the case of pitch extraction type electronic guitar,
The vibration generated in the strings is converted into an electric signal by the pickup,
The fundamental frequency (pitch of a musical tone) included in the signal is extracted. In order to control the sound source, it is necessary to separate the component corresponding to the scale tone and the component (pitch bend) component from the scale tone from the extraction result (as long as the bend range data is used). However, this separation is essentially impossible. Because, when choking operation (pitch bend operation) is not applied to the string, the string is pressed against the fingerboard and plucked, and when choking operation is applied (the string is displaced), it is slightly closer to the head. This is because vibration having the same fundamental frequency can occur when plucking a string while pressing it against the fingerboard. For this reason, the means for separating the scale note component (note number) and the pitch bend component from the pitch extraction result, when the pitch is first extracted, by referring to the internal scale table, , The pitch of the scale note closest to the first pitch is the note number component, and the rest is the pitch bend component (the first extracted pitch may be processed without the pitch bend component). In any case, the pitch extracted first becomes the reference, and if there is a change in the pitch extracted after that, the pitch bend operation data is generated with the first pitch as the reference. This pitch bend operation data is normalized according to the pitch bend range data to give a pitch deviated from the scale note. If the guitar player performs plucking operation without choking in choking operation, the pitch extracted first is defined by the fret position as long as accurate pitch extraction is performed. Components (pitch bend components) other than the scaled notes that are played are not included. Although this is a performance limitation for guitar players, there are many players who are not so concerned. But unlike keyboardists, many guitarists,
Especially, electric guitarists often use choking operation. Also, unlike the bender wheel of an electronic keyboard instrument, there is no clear limit to the magnitude of the change in the string displacement or the string tension caused by the choking operation. Further, not only the choking operation but also the operation of the tremolo arm changes the tension of the string, and the frequency of the string vibration also changes. Further, as a more fundamental problem, in the case of a stringed instrument, it is not easy to produce a sound whose pitch does not fluctuate, and the pitch (string vibration frequency) constantly fluctuates more or less. Due to these various factors, the meaning of the pitch bend operation data, which is the information in the electronic stringed instrument (the set pitch bend range data, that is, the data object to be normalized by the sensitivity data), becomes unclear. Moreover, the pitch bend operation (choking operation, tremolo arming operation) is a favorite of many guitar players. Here, in a complex tone output form called a combination mode, if pitch bend is applied to each tone system by using different pitch bend range data for each system, the pitch bend operation is difficult for the performer to control. Become. First, the guitar player must be able to intuitively understand how much pitch bend operation is applied and how much pitch bend is applied to the musical sound of each system. In addition, it is necessary to have an ear for distinguishing the pitches of musical sounds of different systems that are moving independently. Also, since many electronic guitars can output a live sound (electric sound), many players want to have a synth sound with a pitch bend combined with the live sound.

Therefore, under such an environment, it is desired that a common pitch bend is applied to all musical tone systems.

However, in order to achieve this in the prior art, the pitch bend setting data that was purposely set systematically with different values is discarded, one system is selected and the same pitch bend setting data is input, and one system is also used. It was necessary to reset the troublesome setting of selecting the same and inputting the same pitch bend setting data.

[Object of the Invention] Therefore, the object of the present invention is to purposely re-input the pitch bend setting data for each system when it is desired to apply a common pitch bend effect to musical tones of all systems in the combination mode as described above. It is an object to provide a pitch control device for an electronic musical instrument that does not have the above.

According to the present invention, in order to achieve the above object, the sound source can be controlled in response to the performance control input from the performance control input device, and the sound source can generate a plurality of musical tones. In a pitch control device for an electronic musical instrument, a mode switching means for selecting a first and a second musical instrument playing mode according to a difference in playing method with respect to the performance control input device, and a first mode switching means for selecting the mode.
When the musical instrument playing mode is selected, the pitch bend setting means for each system for setting the pitch bend setting data for each system and the mode switching means are used so that independent pitch bend is applied to each system. A common pitch bend setting means for collectively setting common pitch bend setting data so that a common pitch bend is applied to the plurality of systems when the two musical instrument playing modes are selected. A pitch control device is provided.

According to this configuration, pitch bend for each system is applied depending on what type of musical instrument controller is used as the performance control input device, or even when the same performance control input device is used, due to the difference in the performance form due to the music or the like. It is possible to easily select whether or not to apply a pitch bend common to the system.

By the way, it is more convenient for the performer if it is possible to switch between a common pitch bend and separate pitch bends at a break of a passage during a performance.

Therefore, according to another aspect of the present invention, the pitch control of an electronic musical instrument capable of generating a plurality of musical tones by the sound source by controlling the sound source in response to the performance control input from the performance control input device. In the device, pitch bend setting means for each system for setting pitch bend setting data for each system, mode specifying means for selectively specifying a common pitch bend control mode, and the common pitch bend control mode is specified by the mode specifying means. If not, according to the pitch bend setting data set for each system by the above system pitch bend setting means, for the tone of the corresponding system,
When a pitch bend is added and the common pitch bend control mode is designated by the mode designating means, the pitch bend set data for any one of the pitch bend setting data set by the system-specific pitch bend setting means is set. A pitch control device for an electronic musical instrument is provided, which comprises pitch bend addition means for adding pitch bend to all tones of a system to which pitch bend is added according to setting data.

In the case of this configuration, it is possible to switch the control from one system to another, or from common system to another system during performance.

Further, in a preferred configuration example, the mode designating means uses the pitch bend setting data set for any system of the pitch bend setting data set by the system-specific pitch bend setting means, and the common pitch bend control by the pitch bend adding means is performed. It has a means to select whether to perform.

Alternatively, instead of the selecting means, a means for selectively instructing to perform the common pitch bend control with the content set by the common pitch bend data setting means may be used.

Like the sound of
In a mode in which musical tones of each system are generated on the corresponding musical tone generation channels of the sound source), the present invention relates to a technique for setting the mode of the pitch bend effect applied to the musical tones of each system. Independent pitch bend range data can be set for each, or pitch bend range data common to the system can be set.

Hereinafter, how the principle of the present invention is embodied in this embodiment will be described.

<Pitch Bend Setting Switch / Display> FIG. 4 shows the switches related to the pitch bend setting among the switches 1-3 of FIG.

First, 4A and 4B are mode changeover switches that can be selected depending on the difference in performance method for the performance control input device. Here, 4A is a keyboard mode selection switch (Key
board), 4B is a guitar (string instrument) mode selection switch (w
ind). Keyboard mode selection switch 4A
Can be operated when a keyboard is used as a performance control input device, and the guitar mode selection switch can be operated when a guitar (stringed instrument) controller is used as a performance control input device. In the case of the electronic musical instrument 1 of the embodiment, the main body is a keyboard musical instrument, so when playing on the main body, the keyboard mode is set, and as an external electronic musical instrument (MIDI controller) connected via MIDI 1-6, an electronic stringed instrument such as an electronic guitar is used. When using, you can select the guitar mode.

4J is a switch (SPLIT) for designating a split (a function that switches tones depending on the range or playing touch), which is one mode of the combination mode, and 4K is a tone mix (one or more systems of tone This is a switch (TONE MIX) for specifying the function to be combined and output. In this example, all four systems (1/2/3/4, 1 + 2 + 3 + 4) are assumed.

4F, 4G, 4H, and 4I are switches (AREA) for selecting the system number when setting the system data. Switch 4F specifies the first system and switch 4G specifies the second system. , Switch 4H specifies the third system, switch 4I is the fourth
Specify the lineage.

4L and 4M are cursor switches (CURSOR), which are used to carry a screen cursor from the LCD display screen of the display unit 1-5 to select an item of setting data when setting data.

4D and 4E are data input switches (VALUE), and when setting numerical data, the numerical value increases by pressing the up switch 4E indicated by ON, and the numerical value decreases by pressing the down switch 4D indicated by OFF. When setting on or off, switch 4E turns on and switch 4D turns off.

4C is pitch bend range display switch (BEND RANGE)
And is used to select the setting screen for bend range data.

In Fig. 5, press the keyboard 4A of the mode selection switch,
Press the Tone Mix Switch 4K in the combination,
When the bend range switch 4C is pressed, the display unit 1-5
Shows the contents of the bend range data displayed on the screen. At the bottom of the screen, one of the 1 + 2 + 3 + 4 system is displayed in reverse video so that it can be seen which system of the tones has the set content (1st, 2nd, 3rd, and 4th).
System). In the keyboard mode as shown,
Items to be set are system number (selected by area switch 4F to 4I), selection, and bend range (BEND RANGE)
Data. In the case of the keyboard mode, since there are a total of four musical tones, it is necessary to set bend range data for four channels.

FIG. 6 shows an example of the contents displayed on the screen of the display unit 1-5 when the mode selection switch selects the guitar 4B, the tone mix switch 4K is pressed in the combination, and the bend range switch 4C is pressed. is there. In the guitar (stringed instrument) mode, the bend range data is set all at once, so that all 1 to 4 are highlighted in the lower part of the display section. In guitar mode, setting work is easier because it is not necessary to set bend range data for each system.

<Bend Range Data Setting> FIG. 7 is a flowchart of the bend range data setting process executed when the combination is selected and the bend range is selected. This process is a subroutine in the switch change process 3-3 in FIG.

In 7-1, it is determined whether or not the keyboard mode is selected, and if it is the keyboard mode, a screen as shown in FIG. 5 is displayed in 7-2. (However, in split mode, the combination display format is 1/2/3/4.) The actual display is executed only when the bend range switch 4C is pressed. As a front surface, the system 1 is highlighted in the combination display section. The same applies to the case of 7-7). Then, depending on which switch is pressed, the processings 7-3 to 7-12 are selectively executed. For example, when one of the area keys 4F to 4I is pressed, the system corresponding to the pressed area key is highlighted and the internal (on RAMI-9) bend range data setting area is switched (7-3, 7-4). Also,
When the value key 4E is pressed, the value of the data in the selected pitch bend range data setting area is increased by 1 (fixed if the upper limit is reached), and when the value key 4D is pressed, the value of the data in that area is decreased. 1 (7-5, 7-6: 7-7, 7-8).

On the other hand, in the case of window mode (YES in 7-9)
Executes the processing shown in 7-7 to 7-11. The difference from the keyboard mode is that all channels 1 to 4 are highlighted in the combination display on the screen and the area key.
There is no processing for 4F-4I. In this mode, the bend range data is internally set in the bend range data setting area for system 1. Therefore, the user only needs to input the bend range data for one system, and the setting work becomes very easy.

The details of the pitch bend execution process (which is performed in the musical tone pitch changing process 2-2-4 in FIG. 2B) are not shown, but the keyboard mode is changed to the keyboard mode under the combination mode (split or tone mix). If it is, the data of the bend range setting area for one or a plurality of systems in which the musical tone is generated among the four systems of the pitch bend setting area in the RAM1-9 is referred to for each system, that is, the first system. Tones of a system are referred to in the form of bend range setting data of the first system, are calculated, are incorporated into pitch data, and are tones generating the tones of the corresponding system in the sound source 1-9. Transferred to the originating channel.

On the other hand, in the guitar mode, the data of the bend range setting area of the first system (the four bend range setting areas prepared for the pitch bend data for each system) is set for any tone system. Bend range data in the first area of) is read out and calculated,
It is incorporated in the pitch data and transferred to the sound source 1-9.

Therefore, in the case of the embodiment, in the pitch bend execution processing, independent bend bends are attached to the musical tones of each system by the bend range setting data for each system, or the system is determined based on the bend range setting data of the first system. Whether or not a common pitch bend is applied to the musical sound of is determined by the instrument playing mode (keyboard mode or guitar mode) at the time of execution, so if you switch the mode switch 4A, 4B during the performance, how the pitch bend is applied even during the performance Can also be easily replaced.

Since the present embodiment operates as described above, as in the case of an electronic stringed instrument, the information of the scale note and the information of the pitch deviation from the scale note are input in an undifferentiated form from the same operator (string). Different from a system that processes a signal input from a sensor such as a microphone (for example, an electronic trumpet that uses a microphone as a sensor) or a bender wheel, a pitch bend operator whose end point of bend operation is unknown By setting a common pitch bend range for a system used as, a common pitch bend can be attached to musical tones of a plurality of systems in the combination, and the setting work is easy. Further, it is possible to immediately deal with the shift to the common pitch bend control during the performance (for example, by pressing the switch 4B while the keyboard 3 is playing).

[Modification] The embodiment has been described above, but various modifications and changes can be made without departing from the scope of the invention. For example, if you want to add a pitch bend effect that is common to all systems without setting the pitch bend setting data that is common to all systems, from among the pitch bend setting data that has already been set for each system,
A favorite one may be selected and pitch bend control for all systems may be performed based on the data.

Further, in the embodiment, the common pitch bend setting data is
Although the input is made to the area of the first internal system used in the system-specific mode, it may be input to another area that is not used in the system-specific mode.

[Effects of the Invention] As is apparent from the above description, according to claim 1, the sound source can be controlled in response to the performance control input from the performance control input device, and the tone generator can generate a plurality of musical tones. In a pitch control device for an electronic musical instrument, a mode switching means, a mode switching means for selecting a first and a second musical instrument playing mode according to a difference in playing method with respect to the performance control input device, and a mode switching means When the musical instrument playing mode No. 1 is selected, the pitch bend setting means for each system for setting the pitch bend setting data for each system and the mode switching means so that the independent pitch bend is applied for each system. When the second instrument playing mode is selected, the common pitch bend setting data is collectively set so that the common pitch bend is applied to the plurality of systems. If the pitch bend setting data is set by the common pitch bend setting means, the common pitch bend effect is applied to musical tones of all systems according to the setting contents. Therefore,
There is an advantage that it is not necessary to reset the data for each system.

Further, since the mode switching means is means for selecting a musical instrument performance mode according to a difference in performance method for the performance control input device, it can be easily systematized according to what type of musical instrument controller is used as the performance control input device. / Common settings can be switched.

According to a second aspect of the present invention, in a pitch control device for an electronic musical instrument, which is capable of controlling a sound source in response to a performance control input from a performance control input device to generate musical tones of a plurality of systems by the sound source, pitch bend for each system System-specific pitch bend setting means for setting the setting data, mode specifying means for selectively specifying the common pitch bend control mode, and the system-specific pitch bend setting when the common pitch bend control mode is not specified by the mode specifying means. According to the pitch bend setting data set for each system by means, pitch bend is added to the tone of the corresponding system, and when the common pitch bend control mode is designated by the mode designating means, it is set by the system pitch bend setting means.
