Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for selecting an effect to be added to an audio signal or a musical sound signal according to an effect type.
[0002]
[Prior art]
In an electronic musical instrument, various effects are added to a musical sound signal generated by a sound source and output to a sound system. The user selects at least one effect type from among a plurality of effect types prepared in advance and sets a corresponding effect.
However, the increase in effect types in recent years has made it difficult for users to select the effect type.
Conventionally, electronic musical instruments have been categorized so that one can be easily selected from a large number of musical tone control characteristics. The user first selects a category, and then finds and selects a desired tone control characteristic from the selected category.
For example, in Patent Document 1, timbres are classified into categories, and a desired timbre is selected based on the above-described categories.
[0003]
In Non-Patent Document 1 and Non-Patent Document 2, some of the effect types are also categorized.
As for the effect type, there is a type in which a plurality of different effects are simultaneously added to a musical sound signal even if it is one effect type.
However, even with an effect type (hereinafter referred to as “composite effect type”) in which a plurality of effects are added simultaneously, only one category is associated, making it difficult to find a composite effect type.
[0004]
For example, the composite effect type “Auto Wah + Dst (auto wah + distortion)” is associated with only one category “wah”.
If the user is familiar with music, when finding “Auto Wah + Dst”, the category of “wah” that is considered to be more relevant than “dst” is selected.
On the other hand, the general user may try to find out in the category of “dst”. However, in the “dst” category, “Auto Wah + Dst” cannot be found.

The RAM 4 is provided with a working area for the CPU 2. The CPU 2 loads the electronic music apparatus control program stored in the ROM 3 into the RAM 4 and performs various controls such as input / output control.
[0009]
Here, the relationship between the effect and the effect type will be described.
The effect is a function of processing the musical sound signal and adding various effects, and is executed by the effect circuit 10. When this function is realized by digital signal processing, it can be called an effect program. A plurality of effects (effect programs) are prepared in advance in the ROM 3 or the like.
The effect type is data for selecting the content of the effect executed by the effect circuit 10 (and instructing the effect circuit 10 to set the effect).
In the electronic music apparatus, data of a plurality of effect types is prepared.
The data of each effect type includes, for example, an effect type name, a category, an effect program number, and a plurality of effect parameter values.
[0010]
The effect type name is data displayed on the display unit 8.
The category is data representing the category to which the effect type belongs, and includes one or more categories together with the priority of the category.
The effect program number is a number that designates an effect program to be executed (set) by the effect circuit 10.
The values of the plurality of effect parameters are values of various parameters set in the effect circuit 10 when the effect program is executed, and are data that determine the detailed operation mode of the effect program set in the effect circuit 10. is there.
[0011]
If the ROM 3 does not store an electronic music device control program or data required for processing, such as effect type data, these programs and data may be stored in an external storage device (not shown) and read into the RAM 4. Good.
Further, as a communication interface 12 to be described later, a communication interface for connecting to a communication network is used to connect to a server computer as an external device 13, and a program or data is newly installed from the server computer to an external storage device. You may install updates.
Reference numeral 5 denotes an operator, which includes a performance input switch such as a keyboard and a selection switch. The selection switch selects a tone color or an effect type. The detection circuit 6 detects the operation of the operator 5 and outputs it to the bus 1.

[0014]
FIG. 2 is an explanatory diagram showing a specific example of effect types and categories.
FIG. 2A is an explanatory diagram showing the association between effect types and categories associated with priorities according to the contents of each effect type.
As described above, this association is defined by the fact that the category associated with each effect type is included in the data of each effect type together with the priority of this category.
2 (b), 2 (c), and 2 (d) are respectively selected as “wah”, “dst”, and “dly” categories as will be described later with reference to FIG. 3 (b). It is explanatory drawing which shows the order (list of effect types) displayed on the indicator 8 at the time of being performed.
[0015]
Actually, there are many effect types, but only some of them are illustrated. The illustrated categories are “dst (distortion)”, “wah (wah)”, “cmp (compressor)”, and “dly (delay)”, but there are actually other categories.
Here, “dst” is a category that is associated with an effect type that intentionally generates saturation distortion of a guitar amplifier by an operation such as cutting the top and bottom of a signal waveform.
“Wah” is a category associated with the effect type that changes the brightness of the sound by changing the cutoff frequency of the low-pass filter.
“Cmp” is a category associated with an effect type that suppresses output when a signal of a set level or higher is input.
“Dly” is a category associated with an effect type that delays an audio signal.
[0016]
In the case of a composite effect type in which a plurality of different categories are associated with each other, the plurality of categories are associated with priorities such as a first category, a second category, a third category, and so on. The first category has the highest priority, and has the lowest priority in the order of the second category and the third category. There is no particular limitation on the number of categories to be associated.
The priority order of the category associated with each effect type may be set according to the relevance with the content of the effect type, for example. Set a higher priority for categories that are more relevant to the effect type.
In the case of an effect type that can be associated with only a single category, that category is the first category.
[0017]
“Distortion”, “Auto Wah”, “Touch Wah”, “Compressor”, “Delay”, “Tempo Delay” Since is associated with a single category, each category is a first category.
In contrast, "Auto Wah + Dst (Auto Wah + Distortion)", "Wah + Dst + Dly (Wow + Distortion + Delay)", "Cmp + Dst (Compressor + Distortion)", "Cmp + Dst + Dly (Compressor + Distortion + Delay)" Type.
“Auto Wah + Dst” is associated with “wah” as the first category and “dst” as the second category.
“Wah + Dst + Dly” is associated with “wah” as the first category, “dst” as the second category, and “dly” as the third category.
“Cmp + Dst” is associated with “dst” as the first category and “cmp” as the second category.
“Cmp + Dst + Dly” is associated with “dst” as the first category, “dly” as the second category, and “cmp” as the third category.
[0018]
FIG. 3 is a flowchart for explaining processing for selecting an effect type.
1 is executed by a part of the electronic music apparatus control program (effect type selection program) executed by the CPU 2 in the hardware configuration shown in FIG.
FIG. 3A is activated when the user moves to a menu screen for selecting an effect type by operating an operator. A plurality of categories are displayed on the menu screen.
When one of the displayed categories is selected by the operator in S21, a list of effect types belonging to the selected category is created and displayed on the display unit 8 in FIG. 1 in S22. If not selected, the process proceeds to the next S23 without performing the process of S22.
[0019]
FIG. 3B shows details of S22 in FIG.
The effect type associated with the selected category is searched with reference to data of all effect types.
In S31, the variable N is initialized to 0. The variable N is a value indicating the priority order of the category.
In S32, the variable N is increased by 1.
In S33, by referring to data of a plurality of effect types, it is determined whether or not there is an effect type associated with some category in the Nth category.
If there is even one corresponding effect type, the process proceeds to S34. If not, all the associated categories are referred to for all effect types, so the process proceeds to S35.
[0020]
In S34, it is determined whether or not there is an effect type that associates the selected category with the Nth category. If there is an effect type, the process proceeds to S36, and the corresponding effect type is listed in the list of effect types currently created. Add to the end (add so that the effect type with the higher priority of the selected category is displayed on the list), and return to S32.
In S32, the value of N is increased by 1 and the same processing is repeated.
On the other hand, in S35, control is performed so that the completed effect type list (effect type name list) is displayed on the display 8, and the process returns to S23 in FIG.
As a result, the display unit 8 displays a list of the effect types associated with the selected category in a priority order corresponding to the priority order of the selected category in each effect type.
For example, the priority order for display is determined in the direction of the lower position in order from the upper position where the position is easy to find. Alternatively, the time until display is determined in order of decreasing time until display.
[0021]
In S23 of FIG. 3A, it is determined whether or not an effect type has been selected from the list by the user.
If it is selected, the process proceeds to S24, and an effect is set according to the selected effect type. That is, the effect program and the effect parameter value specified by the selected effect type are set in the DSP of the effect circuit 10 in FIG.
In S25, when the user instructs the end of the selection, the effect setting process is ended. Otherwise, the process returns to S21.
[0022]
Here, the above-described operation will be described using the specific example shown in FIG. 2B on the premise of the association between the effect type and the category shown in FIG.
In this case, the category “wah” is selected in S21.
When N = 1 for the first time in S32, a certain category is associated as the first category by referring to the data of a plurality of effect types having the correspondence shown in FIG. 2A in S33. Determine that there is an effect type.
In S34, it is determined that there is an effect type having “wah” as the first category. In S36, “Auto Wah”, “Touch Wah”, “Auto Wah + Dst”, and “Wah + Dst + Dly” are added to the effect type list as corresponding effect types, and the process returns to S32.
[0023]
Since N = 2 in this S32, it is determined in S33 that there is an effect type associated with some category as the second category. However, in S34, since it is determined that there is no effect type having the category “wah” as the second category, the process immediately returns to S32.
Since N = 3 in this S32, it is determined in S33 that there is an effect type associated with some category as the third category. However, in S34, since it is determined that there is no effect type having the category “wah” as the third category, the process immediately returns to S32.
[0024]
In this S32, N = 4. If it is assumed that there is no fourth category or less in the data of the plurality of effect types having the correspondence shown in FIG. 2A, the process proceeds from S33 to S35, and a list of effect types is displayed. The effect type names are displayed on the display 8 in the priority order shown in FIG.
Next, returning to S23 of FIG. 3A, if the user selects the effect type “Touch Wah”, the effect program designated by the effect program number included in the data of this effect type in S24. Then, the values of a plurality of effect parameters included in the effect type data are set in the effect circuit 10.
[0025]
Next, the processing operation described above will be described with reference to the specific example shown in FIG.
In this case, the category “dst” is selected in S21 of FIG.
When N = 1 in S32, the process proceeds from S33 to S34 to S36, and the effect types “Distortion”, “Cmp + Dst”, and “Cmp + Dst + Dly” having the category “dst” as the first category are added to the effect type list. The
When N = 2 in the next S32, the process proceeds to S33 → S34 → S36, and the effect types “Auto Wah + Dst” and “Wah + Dst + Dly” having the category “dst” as the second category are already in the list. Added under one effect type.
When N = 3 in the next S32, the process proceeds from S33 to S34 to S32.
When N = 4 in the next S32, the process proceeds from S33 to S35 to display the effect type name list. The effect type names are displayed on the display 8 in the priority order shown in FIG.
[0026]
Next, the processing operation described above will be described using the specific example shown in FIG.
In this case, the category “dly” is selected in S21 of FIG.
When N = 1 in S32, the process proceeds from S33 to S34 to S36, and the effect types “Delay” and “Tempo Delay” having the category “dly” as the first category are added to the effect type list.
When N = 2 in the next S32, the process proceeds from S33 to S34 to S36, and the effect type “Cmp + Dst + Dly” having the “dly” category as the second category is below the above-described two effect types in the list. To be added.
When N = 3 in the next S32, the process proceeds from S33 to S34 to S36, and the effect type “Wah + Dst + Dly” having the “dly” category as the third category is already below the above three effect types in the list. To be added.
When N = 4 in the next S32, the process proceeds from S33 to S35, and a list of effect types is displayed. The effect type name list is displayed on the display 8 in the priority order shown in FIG.
[0027]
As is clear from the specific example described above, when the user wants to set a desired effect type “Auto Wah + Dst” associated with “wah” and “dst”, for example, it is included in this composite effect type. Regardless of which category “wah” or “dst” is selected, the desired effect type “Auto Wah + Dst” can be found in the display list.
Here, when the category “dst” having a low priority is selected for the desired effect type “Auto Wah + Dst”, “Auto Wah + Dst” is the priority order after the effect type having the high priority, and is below the list. Will be displayed.
On the other hand, when the category “wah” having a high priority is selected for the desired effect type “Auto Wah + Dst”, “Auto Wah + Dst” is displayed at the top of the list having the high priority.
As a result, the user who is familiar with music selects the category “wah” having a higher priority, and therefore can quickly find and select a desired effect type (Auto Wah + Dst).
Note that when the number of effect types that can be displayed at a time is limited on the display device 8, the display is sequentially scrolled so that the ones behind the priority order can be seen.
[0028]
In the above description, the CPU 2 performs effect type display control according to the correspondence shown in FIG. 2A by referring to the data of each effect type stored in the storage device such as the ROM 3 or the RAM 4. It was.
Instead of this, the correspondence relationship itself shown in FIG. 2A is stored in the ROM 3 or RAM 4 as table format data, and the effect type display control is performed by referring to this. Also good.
Alternatively, for each category, list data of effect types arranged in the priority order corresponding to the priority order of the category for each effect type is created in advance and stored in the ROM 3 or RAM 4, so that FIG. You may prescribe | regulate the correlation shown by. When a certain category is selected, the CPU 2 performs display control of reading and displaying a list of effect types corresponding to the selected category.
In this case, the required storage capacity increases, but as soon as a category is selected, a list can be displayed in an order corresponding to the priority order.
Further, instead of storing the association between the effect type and the category as data, it may be possible by the program itself. For example, the program step may be described so that when the determination step in the program inputs a selected category, a list of results corresponding to the above-described association is output.
[0029]
In the above description, the association between the effect type and the category is fixed.
On the other hand, the program may have a function of editing the category associated with the effect type and / or the priority of the category by the user. The user can freely make a desired association. The edited association data may be stored in an external storage device.
In addition, the program may have a function of automatically editing the priority order of the category frequently selected by the user so as to increase the priority order according to the frequency.
[0030]
When each effect type is displayed on the display device in a priority order corresponding to the priority order of the selected category in each effect type, for example, among a plurality of category types having the same category priority order, for example, FIG. In “Distortion”, “Cmp + Dst”, and “Cmp + Dst + Dly” in (c), it is preferable to arrange in order from a representative effect or an effect having a high importance.
For example, in S33 of FIG. 3B, when searching for a selected category with reference to a plurality of data of each effect type, a representative effect or a highly important effect is stored in order. Then, the above-described arrangement can be realized by searching in order from representative effects or effects of high importance and adding them to the effect type list.
[0031]
The present invention can also be applied to an electronic music apparatus in which an electronic music program is installed in a personal computer.
In the above description, an effect is added to the musical sound signal generated by the sound source. However, some electronic music devices have a function of adding an effect to an audio signal (vocal sound) obtained by collecting a user's singing voice with a microphone and outputting the signal. The present invention can also be applied to effects applied to sound signals such as musical tone signals or audio signals.
Therefore, the present invention is not limited to an electronic musical instrument or a personal computer, but an effect is applied to a sound signal such as a musical sound signal or a sound signal in an audio mixer, a karaoke device, a game device, a portable communication terminal such as a mobile phone, etc. It can also be applied to.
[0032]
【The invention's effect】
As is clear from the above description, the present invention can display a desired effect type associated with a plurality of categories regardless of which of the plurality of categories is selected. There is an effect that it can be selected.
Among the plurality of displayed effect types, there is an effect that a selected category having a higher priority can be quickly selected.
