Description

  The present invention relates to a musical tone synthesizer and a program suitable for use in an electronic musical instrument capable of tone editing.

Conventionally, in an electronic musical instrument such as a synthesizer, timbre editing (voice editing) can be performed by a user specifying various timbre parameter values. However, the number of timbre parameters that can be specified is enormous, and it is not easy to determine which one of the timbre parameters to select and what parameter value to specify will result in the timbre imaged by the user. Deep knowledge is required.
For this reason, various techniques have been proposed so that even a user with little knowledge can easily edit the timbre. For example, Patent Document 1 discloses a technique for editing a timbre parameter using a “timbre editing template” that matches each timbre type. The timbre type is a group of timbres such as “piano” and “analog”, for example, and the timbre editing template is a predetermined number (for example, “4”) to be edited corresponding to the selected timbre type. ) Parameters are defined. The operation panel of the electronic musical instrument is provided with the same number of knobs as the predetermined number, and the user can increase or decrease the parameter value by operating these knobs. Therefore, if the most suitable parameter is designated in the timbre editing template according to the timbre type, the user can reduce the trouble of selecting the parameter to be edited from among the enormous parameters.

JP 2010-237510 A

However, the technique disclosed in Patent Document 1 still has the following problems. First, the value of the parameter assigned to the knob must be determined by operating the knob for each parameter, which is troublesome. Also, the user must decide by himself which one of the predetermined number of parameters should be selected (combined) in order to create the sound he / she imagines. Even though the number of parameters to be manipulated has decreased to the predetermined number, it is still difficult for users without knowledge to select parameters. In addition, by reducing the number of parameters that can be operated to the predetermined number, there is a new problem that there is no guarantee that if only the predetermined number of parameters are adjusted, the sound as expected can be obtained. Yes. Further, as a result of adjusting the value of each parameter, there is a problem that it is difficult to predict what effect will be exerted on the sound until the sound is actually heard after editing the parameter value.
The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a musical tone synthesizing apparatus and program capable of realizing a sound imagined by a user with a simple operation.

In order to solve the above problems, the present invention is characterized by having the following configuration. The parentheses are examples.
The musical tone synthesizer according to claim 1, wherein the musical tone signal synthesizing means (12) for synthesizing musical tone signals based on a plurality of parameters, and the parameter values of one or a plurality of parameters are changed according to a predetermined user operation. And a template storage means (20) for storing at least the one template, wherein the data defining the mode and the character string are set as one parameter set, the group consisting of a plurality of parameter sets is set as one template, and the current editing target An edit item name display section that displays the item name that is displayed, and character strings included in a plurality of parameter sets that belong to the specified template and that are arranged around the edit item name display section An edit screen (Fig. 2 (a)) consisting of parameter set corresponding parts with different markings is displayed. When one of the character strings displayed on the edit screen is designated in accordance with the edit screen display means (10, SP2) and the user operation, the mode defined in the parameter set relating to the designated character string When the parameter value operating means (SP12) for changing the parameter value of one or a plurality of parameters and the character string corresponding to any parameter set belonging to the specified template are specified, the specified character Marking assigning means (SP14) for applying markings related to the markings applied to the parameter set corresponding part relating to the parameter set corresponding to the column to the edit item name display part.
According to a second aspect of the present invention, the tone signal synthesizing means (12) for synthesizing the tone signal based on a plurality of parameters, and the parameter value of one or more parameters are changed according to a predetermined user operation. A template storage means (20) for storing at least the one template, and a group of a plurality of parameter sets as a template, and a processing device ( 22), which is a program applied to a musical tone synthesizer, and is arranged and designated around an edit item name display section that displays an item name that is currently being edited, and the edit item name display section. The character strings included in multiple parameter sets belonging to the template are displayed and different markings are applied to each. A procedure (SP2) for causing the display means (10) to display an edit screen (FIG. 2 (a)) composed of the parameter set corresponding portion and a character string displayed on the edit screen in response to a user operation. When one of them is specified, a procedure (SP12) for changing the parameter value of one or a plurality of parameters in a manner defined in the parameter set relating to the specified character string, and any of the specified templates When a character string corresponding to the parameter set is designated, a marking related to the marking applied to the parameter set corresponding part related to the parameter set corresponding to the designated character string is displayed in the edit item name display part. It is a program for causing the processing device (22) to execute the application procedure (SP14).

  In the present invention, an edit item name display unit that displays the name of an item that is currently being edited, and characters included in a plurality of parameter sets that are arranged around the edit item name display unit and belong to a specified template When an edit screen is displayed that includes a parameter set corresponding part that displays columns and is marked differently for each, and a character string of any parameter set that belongs to the specified template is specified by the user Marking related to the marking applied to the parameter set corresponding part relating to the designated character string is applied to the edit item name display part. This makes it easy to know which parameter set is currently being edited from the relationship between the markings on the edit item name display section and the markings on the parameter set corresponding section. In addition, the character or image of the sound realized by the parameter set currently being edited can be symbolically grasped from the character string. In addition, since it is possible to easily make each character string a character string representing a sound feature or image realized by a parameter set corresponding to the character string, a parameter value that realizes the sound imaged by the user Editing can be realized with a simple operation.

1． Hardware Configuration of Embodiment Next, the hardware configuration of an electronic musical instrument according to an embodiment of the present invention will be described with reference to FIG.
In the figure, reference numeral 2 denotes a performance operator, which includes a keyboard, a pedal, a pitch bend wheel, and the like. The operation state for the performance operator 2 is detected by the detection circuit 4, and a signal indicating the operation state is output via the bus 16. Reference numeral 6 denotes a setting operator, which includes buttons and the like for setting various operation modes. The operation state for the setting operator 6 is detected by the detection circuit 8, and a signal representing the operation state is output via the bus 16. Reference numeral 10 denotes a display that displays various types of information to the user based on display information supplied via the bus 16. The display device 10 constitutes a touch panel, and the user's operation content on the screen is output via the bus 16. A tone generator / effect circuit 12 synthesizes a musical tone signal based on the parameter values of various tone color parameters, performs an effect process, and outputs it.

  A sound system 14 emits a musical sound signal supplied from the sound source / effect circuit 12. A CPU 22 controls other components via the bus 16 based on a program described later. Reference numeral 20 denotes a ROM which stores a program and the like which will be described later. Reference numeral 18 denotes a RAM, which is used as a work memory for the CPU 22. The area of the RAM 18 includes a current area 18a that stores current parameter values for each of a plurality of timbres (No. 1 to No. k), and an edit area 18b that is a work area when voice editing is performed for any timbre. And the other region 18c. When the parameter value stored in the current area 18 a or the edit area 18 b is set in the sound source / effect circuit 12, a tone signal corresponding to the set parameter value is generated in the sound source / effect circuit 12.

  A storage device 24 includes a storage medium such as a hard disk, a flexible disk, an optical disk, and a flash memory, and a drive device for the storage medium. Note that the storage medium may be detachable or may be built in the electronic musical instrument. A communication interface 26 inputs / outputs MIDI signals and other control signals to / from external devices. The communication interface 26 may be a wired interface dedicated to music such as MIDI, a general-purpose short-distance wired interface such as USB or IEEE1394, a general-purpose network interface such as IEEE 802.3, or a general-purpose short-range such as wireless LAN or Bluetooth (registered trademark). It may be a wireless interface.

2． When a predetermined operation for designating voice editing (editing of a certain tone color parameter) is performed on the user interface setting operator 6, a voice editing screen shown in FIG. In this screen, reference numeral 50 denotes a parameter operation unit, which is composed of areas divided into 3 rows and 3 columns. Of these areas, the central area constitutes a timbre name display field 55, in which a character string ("Grand Piano 1" in the example shown) representing the currently selected timbre name is displayed. The areas other than the center constitute parameter set buttons 51-54, 56-59. Each of these buttons corresponds to a “parameter set”. Here, the parameter set is, for example, a character string representing a sound image or characteristic such as “distorted sound”, “warm sound”, “dry sound”, “dark sound”, and an image or characteristic of the sound. In order to realize this, the data defines how much the timbre parameter value should be changed.

  When the user presses any of the buttons 51 to 54 and 56 to 59, the value of the timbre parameter is changed based on the associated parameter set. Here, different markings are applied to the buttons 51 to 54 and 56 to 59, respectively. In this embodiment, the “marking” is “background color”. That is, in FIG. 2 (a), the color names (purple, red, etc.) described in parentheses after the symbols 51 to 59 are the background in the initial state of the buttons 51 to 54, 56 to 59 and the timbre name display column 55. Color. The character string related to the button “2” facing each other across the timbre name display field 55 is set to be a synonym. As shown in FIG. 2A, the background color of the timbre name display field 55 in the initial state is “white”, but when the buttons 51 to 54 and 56 to 59 are operated, the background of the timbre name display field 55 is displayed. The color is also updated.

  That is, when any one of the buttons 51 to 54 and 56 to 59 is operated a plurality of times, the corresponding parameter set is also applied a plurality of times, the parameter value is changed each time, and the timbre name display field 55 is displayed. The background color is changed to approach the background color of the operated button. For example, when the button 52 (red) is operated a plurality of times, the background color of the timbre name display field 55 changes from light pink to dark pink, and when the parameter value reaches a limit that can be changed, the button 52 Same red color. In general, a plurality of parameters are specified in the parameter set. Therefore, when one of the parameters reaches a limit value, the “limit that can change the parameter value” may be set. Here, when different buttons are pressed, a color obtained by mixing the background colors of these buttons may be used as the background color of the timbre name display field 55, and the area of the timbre name display field 55 is defined as the buttons 51 to 54,. It may be divided into a plurality of sections corresponding to 56 to 59, and the background color may be changed for each section. Further, when the “2” buttons facing each other across the timbre name display field 55 are alternately operated, the background color change contents by the previous button operation may be canceled. By the above operation on the background color of the timbre name display field 55, the user can display what kind of operation is being performed on the timbre currently selected and how much is displayed on the timbre name display field 55. It can be easily grasped according to the state.

  By the way, the parameter set of “8” displayed simultaneously on the parameter operation unit 50 is collectively referred to as “template”. Reference numeral 60 denotes a template selection unit that selects a template to be displayed on the parameter operation unit 50 based on a user operation. When the template is changed by the operation of the template selection unit 60, the character string displayed on the parameter operation unit 50 is changed as shown in FIGS. 2B and 2C, for example. Therefore, when the desired effect cannot be realized in the currently selected template, the user can continue voice editing while switching the template. Here, each template can be applied to any timbre, but an optimum template used for the timbre to be edited is defined as a default template for the timbre. For example, for a guitar tone, it is preferable to use a template including a distortion parameter set as a default template. Reference numeral 62 denotes an EXIT button, which is operated when the operation on the voice edit screen (FIG. 2A) is terminated.

3． Data Structure Next, the data structure of the template described above is shown in FIG. In FIG. 3A, TP1 to TPn are “n” templates and are stored in the ROM 20 or the RAM 18. That is, a basic template is stored in the ROM 20 at the time of shipment from the factory, but the user can also create a template independently thereafter, and the template created by the user is stored in the RAM 18. Each template is composed of a plurality of parameter sets (“8” in this embodiment). In FIG. 3A, “rows” in the frames related to the templates TP1 to TPn are parameter sets.

  Each parameter set includes parameter set name data 30, display name data 32, background color data 34, and parameter operation data 36. Here, the parameter set name data 30 is composed of a character string that uniquely identifies the parameter set. The parameter set name data 30 is composed of a single character such as “A”, and “·” is appended to the single character such as “A.”. There is something you did. Both are parameter sets corresponding to the “2” buttons (for example, buttons 52 and 58) facing each other across the timbre name display field 55 in the parameter operation unit 50 (see FIG. 2A). Next, the display name data 32 represents a character string displayed on the button to which the parameter set is assigned, and the background color data 34 represents the background color of the button.

  The parameter operation data 36 is data for designating a timbre parameter whose value is changed when the parameter set is applied and a change amount of the parameter value for the operation per “1” time. If the parameter value is a continuous amount (eg, time or level), the parameter manipulation data 36 may be data that directly specifies the amount of change, such as that time or level, relative to the current amount. It may be data that indirectly specifies the amount of change by a percentage or the like. In addition, depending on the type of parameter, there may be a case where the parameter value can take only two values, for example, “ON” and “OFF”. In this case, the parameter operation data 36 is data that directly designates “on” or “off”. Further, the parameter operation data 36 may specify the changed parameter value by a conditional expression for the current parameter value. For example, the amount of change may be increased if the current parameter value is less than a predetermined threshold, and the amount of change may be decreased if it is greater than or equal to the threshold. In addition, the parameter operation data 36 is set so that the parameter sets (for example, parameter sets A, A,...) Associated with the “2” buttons facing each other across the timbre name display field 55 have the opposite effects. ing. Here, the “opposite effect” can be realized, for example, by reversing the amount of change for the same parameter, or by turning on an effect that reverses the effect.

  Here, a specific example of the parameter operation data 36 is shown in FIG. 3B, and a general envelope waveform of the tone signal is shown in FIG. As shown in FIG. 3 (c), the time until the envelope waveform level reaches the peak from zero at the time of note-on is called the attack time, and the time when the level falls from the peak to a substantially constant value is called the decay time. Also, the time until the envelope waveform level falls from the above constant value to zero at the time of note-off is called the release time. Next, referring to FIG. 3B, a set of parameter sets having the opposite effect will be described. In the illustrated example, a parameter set for decreasing the attack time and the reverb time by “10” and a parameter set for increasing each by “10” are provided. In the former, a sound that rises quickly and has short reverberation is realized, which is expressed as a “bright sound”. On the other hand, in the latter, a sound with a slow rise and a long reverberation is realized, which is expressed as “dark sound”. The unit of the parameter value shown in FIG. 3B is “millisecond”. As another example, a parameter set for increasing the release time and decay time by “10” and a parameter set for decreasing each by “10” are provided. In the former, a sound with a slow fall at the time of pronunciation and mute is realized, and it is expressed as “a sound with a feeling of air”. On the other hand, in the latter, a sound that falls quickly is realized and expressed as a “hard sound”.

Four. Operation of Embodiment When the user selects a desired tone color to be edited (hereinafter referred to as a target tone color) using the setting operation element 6 and further performs a predetermined operation for designating voice edit, the voice edit shown in FIG. A processing routine is started.
When the processing proceeds to step SP2 in FIG. 4, the contents of the default template for the target tone color are displayed on the parameter operation unit 50 as in the example shown in FIG. Then, the current parameter value of the target tone stored in the current area 18a is copied to the edit area 18b.
Next, when the process proceeds to step SP4, it is determined whether or not an instruction to change the template, that is, whether or not the operation of the template selection unit 60 has been performed. If “YES” is determined here, the process proceeds to step SP6, and another template corresponding to the change instruction is selected as the template to be applied. Next, when the process proceeds to step SP8, the display contents of the parameter operation unit 50 and the template selection unit 60 are updated so as to correspond to the selected template. Thereby, the parameter set included in the selected new template can be selected as an application target. If there is no instruction to change the template, steps SP6 and SP8 are skipped.

  Next, when the process proceeds to step SP10, it is determined whether or not an instruction for selecting a parameter set, that is, an operation of pressing any one of the parameter set buttons 51 to 54 and 56 to 59 has been performed. If "YES" is determined here, the process proceeds to step SP12, the parameter value stored in the edit area 18b is updated based on the parameter set corresponding to the pressed button, and the updated parameter value is It is transmitted to the sound source / effect circuit 12. As a result, when the generation of the musical tone signal related to the target tone color is instructed by the operation of the performance operator 2 or the like thereafter, the musical tone signal based on the updated parameter value is generated. Therefore, the user can confirm the state of voice editing with actual musical sounds by appropriately operating the performance operator 2. Next, when the process proceeds to step SP14, the background color of the timbre name display field 55 is changed so as to approach the background color of the operated button. If there is no instruction for selecting a parameter set, steps SP12 and SP14 are skipped.

  Next, when the process proceeds to step SP16, it is determined whether or not an instruction to end voice editing, that is, an operation of pressing the EXIT button 62 has been performed. If "NO" is determined here, the process returns to step SP4, and the above-described processes of steps SP4 to SP14 are repeated. On the other hand, if “YES” is determined in step SP16, the process proceeds to step SP18, and a “save” button and a “cancel” button are displayed on the display 10 together with a confirmation message as to whether or not to save the voice editing result. (Not shown). When the “save” or “cancel” button is pressed, the process proceeds to step SP20, and it is determined whether or not a save instruction has been issued (whether or not the “save” button has been pressed). If "YES" is determined here, the process proceeds to a step SP22. In this case, the parameter value stored in the edit area 18b is copied to the area related to the target tone color in the current area 18a, and is also stored in the storage device 24 as the parameter value of the target tone color. When the contents of the edit area 18b are stored in the current area 18a and the storage device 24, a new timbre name is assigned and stored as a new timbre defined by the user instead of the original target timbre. May be.

  On the other hand, if "NO" is determined in step SP20, the process proceeds to step SP24, the contents of the edit area 18b are discarded, and the parameter value of the target tone originally stored in the current area 18a is used as the sound source / effect circuit. 12 is transmitted. As a result, when generation of a musical tone signal related to the target tone color is instructed by operating the performance operator 2 or the like thereafter, a musical tone signal based on the parameter value originally stored in the current area 18a is generated. Next, when the process proceeds to step SP26, the voice edit screen (FIG. 2 (a)) is deleted from the display device 10, a predetermined initial screen is displayed on the display device 10, and the processing of this routine ends.

  As described above, according to the present embodiment, the parameter set buttons 51 to 54 and 56 to 59 displayed on the voice edit screen display character strings representing sound characteristics or images of each parameter set. The user can automatically change the values of one or more parameters by simply operating the buttons 51-54, 56-59. Thereby, the user can implement the editing of the parameter value for realizing the imaged sound with a simple operation.

Five. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made as follows, for example.

When “pattern” is applied as the marking, the pattern is preferably darkened gradually in the timbre name display field 55 each time the parameter set button is pressed. When “icons” are applied as markings, the number of “icons” in the timbre name display field 55 may be increased each time the parameter set button is pressed.

(5) In the above embodiment, the template can be selected by the template selection unit 60. However, the template may be fixedly selected according to the target tone color. Further, the template may be switched by “an operation for switching with a switching button”, “an operation for turning pages on the touch panel”, or the like.

(6) In the above embodiment, the default template is determined according to the timbre, but the default template may be common to all timbres.
