Generated and displayed.

  According to a third aspect of the present invention, in the electronic musical apparatus of the first aspect, the storage means further includes a template used for creating the timbre data every time the timbre data is created by the creating means. After the specific information to be stored is stored and the timbre data is generated by the generating means, when the timbre data is generated again, the display means follows the template specified by the specific information corresponding to the timbre data. A timbre data creation screen is created and displayed.

  In order to achieve the above object, the program according to claim 4 can be realized by the same technical idea as claim 1.

  According to the first or fourth aspect of the invention, for each of a plurality of tone types, some tone parameters selected from all tone parameters provided to create tone color data of the tone type are included. Thus, a template for presenting to the user the types of musical sound parameters necessary for creating the timbre data and the parameter information limited to the values that can be taken for each musical sound parameter type is stored and selected by the user.

However, the user can work without hesitation.

It is a block diagram which shows schematic structure of the electronic music apparatus which concerns on one embodiment of this invention. It is a figure for demonstrating the outline | summary of the timbre data creation process which the electronic music apparatus of FIG. 1 performs. It is a figure which shows a part of panel of the electronic music apparatus of FIG. 2 is a flowchart showing a procedure of timbre data creation processing executed by the electronic music apparatus of FIG. 1, particularly a CPU.

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

  FIG. 1 is a block diagram showing a schematic configuration of an electronic music apparatus according to an embodiment of the present invention.

  As shown in the figure, the electronic music apparatus of the present embodiment includes a performance operator 1 including a keyboard for inputting performance data including pitch information, and a plurality of switches and knobs for inputting various types of information. , A setting operator 2 including a slider and a dial, a detection circuit 3 that detects an operation state of the performance operator 1, a detection circuit 4 that detects an operation state of the setting operator 2, and a CPU 5 that controls the entire apparatus. A ROM 6 for storing a control program executed by the CPU 5, various table data, various waveform data, various musical tone parameters, a RAM 7 for temporarily storing performance data, various input information, calculation results, and the like; For example, a display 8 having a small liquid crystal display (LCD) and a light emitting diode (LED) and the like, and various applications including the control program. A storage device 9 for storing a communication program, various music data, various data, etc., an external device (not shown), a communication interface (I / F) 10 for transmitting / receiving data to / from the external device, and a performance operator 1 A tone generator for converting input performance data, performance data obtained by reproducing any of the music data stored in the storage device 9 into a musical sound signal, and imparting various effects to the musical sound signal An effect circuit 11 and a sound system 12 such as a DAC (digital-to-analog converter), an amplifier, and a speaker that convert a musical sound signal from the sound source / effect circuit 11 into sound.

  The components 3 to 11 are connected to each other via a bus 13, and a sound system 12 is connected to the sound source / effect circuit 11.

  The storage device 9 is, for example, a storage medium such as a flexible disk (FD), a hard disk (HD), a CD-ROM, a DVD (digital versatile disc), a magneto-optical disk (MO), and a semiconductor memory, and a driving device thereof. The storage medium may be detachable from the drive device, or the storage device 9 itself may be detachable from the electronic music device of the present embodiment. Alternatively, neither the storage medium nor the storage device 9 may be detachable. The storage device 9 (the storage medium) can also store the control program executed by the CPU 5 as described above. If the control program is not stored in the ROM 6, the control program is stored in the storage device 9. By reading it into the RAM 7, the CPU 5 can be operated in the same manner as when the control program is stored in the ROM 6. In this way, control programs can be easily added and upgraded. Further, although various waveform data and various musical tone parameters are stored in the ROM 6 as described above, the storage device 9 may store the portion that cannot be stored in the ROM 6. Furthermore, instead of providing all waveform data and musical tone parameters used to create timbre data in the device, only frequently used ones are stored in advance in the device, and other than that, when it becomes necessary, For example, it may be acquired from the external device via the communication I / F 10 and stored in the storage device 9.

  As the communication I / F 10, for example, a dedicated music I / F for transmitting and receiving music signals such as MIDI (musical instrument digital interface) signals, and a general-purpose short-distance wired I / F such as USB (universal serial bus) and IEEE1394. And general-purpose network I / F such as Ethernet (registered trademark), and general-purpose short-range wireless I / F such as wireless local area network (LAN) and Bluetooth (registered trademark). In this embodiment, the USB is adopted as the communication I / F 10, but other types of I / Fs may be used instead, and other types of I / Fs may be added thereto. It may be.

  In this embodiment, the electronic music apparatus is constructed on the electronic keyboard instrument. However, the present invention is not limited to this, and may be constructed on a general-purpose PC. In the present invention, the keyboard is not an essential component. In this case, the keyboard may be deleted. Of course, in this case as well, a keyboard may be provided and externally attached to the PC.

  The control process executed by the electronic music apparatus configured as described above will be described first with reference to FIG. 2 and FIG. 3, and then with reference to FIG.

  FIG. 2 is a diagram for explaining the outline of the timbre data creation process executed by the electronic music apparatus of the present embodiment.

  The user selects the “tone data creation mode” from the multiple operation modes, selects the “tone creation function for each type” from the multiple functions in the “tone data creation mode”, and further creates the tone When the timbre type of the data is selected (block B1), a timbre creation screen corresponding to the selected timbre type is displayed on the display unit 8. For example, when timbre type A is selected, a timbre type A timbre creation screen is displayed (block B2), and when timbre type B is selected, a timbre type B timbre creation screen is displayed (block B3). . Note that “type-by-type timbre creation function” is a function for creating timbre data by using a type-by-type timbre creation screen (a superordinate concept of the “timbre type A timbre creation screen” or “tone type B timbre creation screen”) To tell.

  The timbre type A timbre creation screen presents at least some types of musical tone parameters required to create timbre type A timbre data, and at least some of the presented musical tone parameters The setting range and setting unit are also presented in a limited manner. Here, “minimally required” means that the timbre data of the timbre type desired by the user can be created by setting only the musical tone parameters of the presented type. The reason for “presenting the setting range and setting unit in a limited manner” is to prevent creation of timbre data deviating from the normal timbre data of the selected timbre type. It is.

  In the illustrated example, the timbre type A timbre creation screen selects and presents only four types of parameters, and the settable range of each value also presents only a part of the entire range. . The four strips in the square to the right of block B2 indicate different musical tone parameters (the fact that four strips are different types of parameters is indicated by the “parameter type” arrow), and each strip. Indicates the settable range of the corresponding tone parameter value on the tone color type A tone color creation screen (the “value” arrow indicates the direction in which the value increases). Further, the total length of the horizontal side of the square indicates the settable range (that is, the entire range) of each musical tone parameter on the full tone generation screen (block B4). It should be noted that the “four types of parameters” in the illustrated example only present a small number of parameters for the sake of simplicity, and setting the “four types of parameters” simply sets the tone color type A desired by the user. It is impossible to create the timbre data, and it is actually necessary to present and set more parameters than this. The tone color creation screen for tone color type A is generated based on a template set for tone color type A (hereinafter referred to as “parameter restriction template”). However, data contents registered in the parameter restriction template will be described later.

  The timbre type B timbre creation screen differs from the timbre type A timbre creation screen only in the types of musical tone parameters to be presented and the range of values that can be set. Is omitted.

  FIG. 3 is a diagram showing a part of the panel of the electronic music apparatus according to the present embodiment. FIG. 3A shows a timbre creation screen for each type when “piano-type timbre” is selected as timbre type A. FIG. An example is shown, and FIG. 5B shows an example of a tone color creation screen for each type when “analog tone color” is selected as tone color type B.

  Each tone type is associated with a unique screen skin (screen design), and when “Piano tone” is selected, a type-specific tone creation screen 8a is generated and displayed with the “Piano tone” screen skin. On the other hand, when the “analog tone color” is selected, the type-specific tone color creation screen 8a ′ is generated and displayed with the screen skin of the “analog tone color”. As a result, as shown in FIGS. 3A and 3B, the screen designs of the type-specific tone color creation screens 8a and 8a ′ are different.

  The four types of musical tone parameters presented on the type-specific tone color creation screen 8a correspond to the four knobs 2a1 to 2a4 (the “parameter-corresponding physical operators” in the block B5 in FIG. 2) included in the setting operator 2, respectively. ), The user can set the value of the corresponding type of musical sound parameter by operating one of the knobs 2a1 to 2a4.

  A “save” button is displayed on the type-specific tone color creation screen 8a. The user operates the “SAVE” button (in this embodiment, since the touch panel type LCD is not employed as the display 8, the user cannot directly operate the “SAVE” button. The user indirectly operates the “save” button by pressing a switch associated with the “save” button among the switches included in the setting operation element 2. However, the following description will be given. In this case, the button displayed on the display unit 8 is also expressed as “operation”), and the current setting state of each musical tone parameter is stored in the storage device 9 as timbre data. Is done. At this time, information specifying the parameter restriction template and the screen skin (data) used for generating and displaying the type-specific timbre creation screen 8a is added to the timbre data and stored in the storage device 9. ing.

  In addition, a “full” button is also displayed on the type-by-type tone color creation screen 8a. When the user operates the “full” button, as shown in FIG. 2, a transition is made from the type-by-type tone color creation screen 8a to the full tone color creation screen (block B4). On the full tone color creation screen, values of all kinds of musical tone parameters that can be set can be set over the entire setting range. In the full tone creation screen, for example, various musical tone parameters are displayed in a table format, and the user uses a cursor movement switch and a dial (both not shown), which are general-purpose physical operators included in the setting operator 2 (both not shown) (block B6). ), To select the musical parameters to be set one by one and change their values. This selection setting method is not different from the method in the conventional electronic music apparatus (the music synthesizer), and the description thereof is omitted.

  Note that the full tone generation screen and the type-by-type tone generation screens 8a and 8a 'can be shifted to each other as shown in FIG.

  As described above, in the electronic music apparatus of the present embodiment, for each tone color type, only the parameter information limited to the types of musical tone parameters necessary for creating the tone color data of that type and the values that can be taken in that type. A parameter restriction template that presents to the user, selects a parameter restriction template according to the timbre type selected by the user, and creates a type-specific timbre creation screen in which the types and values of the musical sound parameters are limited according to the selected parameter restriction template. Since it is presented, the user can quickly set the type and value of the musical tone parameter necessary for the timbre type being imaged. As a result, the burden on the user when creating the timbre data can be reduced as much as possible.

  In addition, screen skin data with different screen designs is stored for each timbre type, and a timbre creation screen for each type is generated and displayed based on the screen skin data corresponding to the selected timbre type. It is possible to create timbre data of a timbre type that is realistically imaged.

  In addition, for each timbre data that is being created, it is stored which parameter restriction template (and screen skin data) was created, and when the timbre data is called again after exiting the timbre creation screen, the parameter restriction is saved. Since the type-specific tone color creation screen is generated and displayed according to the template (and screen skin data), the user can work without hesitation even when the tone color data creation is continued later.

  Next, this control process will be described in detail.

  FIG. 4 is a flowchart showing a procedure of timbre data creation processing executed by the electronic music apparatus of the present embodiment, particularly the CPU 5. The timbre data creation process is started when the user selects a timbre data creation mode by operating a mode selection switch (not shown) included in the setting operator 2, for example, and another mode is selected. When finished.

The tone color data creation process is mainly performed by (1) type-by-type tone color creation function process (steps S3 to S8) executed when the “type-by-type tone color creation function” is selected.
(2) Full tone generation function processing executed when “full tone generation function” for generating tone data using the full tone generation screen is selected (steps S11 to S13).
(3) Mutual transition processing for mutually transitioning between “type tone color creation function” and “full tone color creation function” (steps S15 and S16)
(4) Saving process for saving the created timbre data (step S10)
It is constituted by.

  When the timbre data creation process is activated, the CPU 5 first determines whether or not the user creates timbre data anew (step S1). For example, it is assumed that the initial screen displayed on the display 8 immediately after the real tone data creation processing is activated includes a “new creation” button and an “edit” button (both not shown). The user operates the “New” button to create new timbre data, and operates the “Edit” button to edit already created timbre data. Therefore, in step S1, the CPU 5 determines whether or not the “new creation” button has been operated. When the “edit” button is operated, a list of already created timbre data is displayed, and the user uses, for example, the cursor movement switch and the “ENTER” switch (not shown) to select from the list. One of them shall be selected.

  As a result of the determination in step S1, when the user newly creates timbre data, the CPU 5 advances the process to step S2, and gives the user any function of “type timbre creation function” or “full timbre creation function”. Asks whether to select. As a result, when the user selects the “type-by-type tone color creation function”, the CPU 5 advances the process to the type-by-type tone color creation function process (1).

  In this (1) type-by-type timbre creation function process, first, the CPU 5 displays selectable timbre type options on the display 8 (step S3), and then the CPU 5 selects one of the timbre types. It waits to do (step S4). When the user selects one of the timbre types, the parameter restriction template and the screen skin data corresponding to the selected timbre type are selected, and “selected data”, which is data for specifying the selected data, is selected. It is added to the timbre data (steps S4 → S5). In this embodiment, the timbre data is created in an edit buffer (not shown) secured at a predetermined position in the RAM 7, whether newly created or edited. The addition of the “selected data” to the timbre data corresponds to storing the “selected data” in a predetermined area in the edit buffer.

Next, data contents registered in the parameter restriction template will be described. The parameter restriction template mainly includes (D1) types of musical sound parameters to be assigned to parameter-compatible physical operators (D2) range of values that can be taken for each musical sound parameter of (D1) (D3) other than the musical sound parameters of (D1) above. Default values of musical tone parameters are registered.

  The type of the musical tone parameter (D1) is a musical tone parameter that is at least necessary for creating the timbre data of the timbre type. Specific examples of the range of values that can be taken by the tone parameter (D2) include the entire range, a partial range, and a discrete value. Further, the tone parameter (D3) is obtained by subtracting the tone parameter (D1) from the types of tone parameters to be set. It is assumed that a default value is set for the tone parameter of (D3) (however, the default value can be changed by moving to the full tone creation screen). In this embodiment, the default value is It is registered in the parameter restriction template. Of course, the default value is not provided for each timbre type, but a common value for all timbre types may be provided for all parameters. In this case, the default value is not registered in the parameter restriction template.

  The screen skin data is stored in advance in the ROM 6 or the storage device 9 in the present embodiment, but may be appropriately acquired from the external device and stored in the RAM 7. The screen skin data includes, for example, display part image data necessary for displaying the tone color creation screen for each type, data indicating its arrangement, background image data, data corresponding to parameter-compatible physical controls and display parts, and parameter-compatible physical data. Display parts after the shape and position have been changed according to the operation of the operation element (when the parameter-compatible physical operation elements are the knobs 2a2 to 2a4, the position indicating the scale is changed from the default position (eg, “0”)) Image data (see FIG. 3), data indicating the color, font, size, and arrangement of each character.

  Next, the CPU 5 assigns the musical sound parameter type to the parameter-corresponding physical operator according to the parameter restriction template selected at the step S5 (step S6), and the type-specific tone color according to the screen skin data selected at the step S5. A creation screen is displayed (step S7). Then, when the user sets the musical tone parameter presented on the type-by-type tone color creation screen using the parameter-compatible physical operator, the CPU 5 sets the corresponding musical tone parameter value in the edit buffer according to the user's operation. Change setting is performed (step S8).

  FIG. 3A shows a type-by-type tone color creation screen when the type-by-type tone color creation function process of (1) is being executed in a state where “piano-type tone color” is selected as the tone type. .

  When “piano-related timbre” is selected as the timbre type, a parameter restriction template associated with “piano-related timbre” is selected (see step S5). The parameter restriction template includes the data of (D1), specifically, the knobs 2a1 to 2a4 (parameter-corresponding physical operators), piano waveform data (“WAVE”), “ATTACK” parameter, “RevSend”. Since the data for associating the “parameter” and the “Cho Send” parameter is registered, after the process of step S6 is executed, the user operates one of the knobs 2a1 to 2a4 to select the corresponding type. The value of the musical tone parameter can be set. On the other hand, when the parameter restriction template is selected, screen skin data associated with “piano-related timbre” is also selected (see step S5). Since the type tone color creation screen 8a is generated and displayed by the screen skin data (see step S7), FIG. 3A shows a state after the processing of at least step S7 is completed. .

  In this state, when the user operates the knob 2a1, for example, the waveform data (“GP”, “UP”, “EP1”, and “EP1”) of the four piano sounds that are presented as piano waveform data (“WAVE”). One of EP2 ") can be selected. The block corresponding to the currently selected waveform data is shaded. Therefore, the waveform data “UP” is currently selected. At this time, if the user rotates the knob 2a1 in the direction in which the clock hand advances, the lower waveform data is sequentially selected each time the knob 2a1 is rotated, and when the waveform data “EP2” is reached, Return to waveform data “GP”. On the other hand, when the knob 2a1 is rotated in the direction opposite to the direction in which the clock hand advances, each waveform data is selected in the direction opposite to the above-described setting direction. Selectable waveform data is limited to instrument sounds, but there are many timbre types such as "piano sounds", "string sounds", and "drum sounds", and a lot of waveform data for each timbre type. As a whole, there are a huge number of waveform data. On the type-by-type tone color creation screen 8a, only four types are selected and presented. “Presenting limited setting range of musical sound parameters” means this.

  On the other hand, the knobs 2a2 to 2a4 are respectively associated with the knobs having the same shape in the type-by-type tone color creation screen 8a. Therefore, when the user rotates any of the knobs 2a2 to 2a4, the type tone color In the creation screen 8a, the corresponding knob is rotated in the same direction, and the corresponding musical sound parameter is set. However, in this case, not all musical tone parameters “ATTACK”, “RevSend”, and “Cho Send” are set over the entire setting range (this is the parameter restriction template (D2)). Specified by data). For example, “ATTACK” defines the duration of the “attack” portion of the selected waveform data. However, in the “piano tone” waveform data, the duration of the “attack” portion is set too long. Therefore, even if the entire setting range is 0 to 127, on the type-specific tone creation screen 8a, for example, it is limited to 0 to 63. Can be set. In addition, the setting unit of the duration of the “attack” portion may be different from the setting unit in the “full tone generation screen”, for example, “4” instead of “1”.

  FIG. 3B shows a type-by-type tone color creation screen 8a ′ when the type-by-type tone color creation function process of the above (1) is executed in a state where “analog tone” is selected as the tone type. ing. This type-by-type tone color creation screen 8a 'differs from the type-by-type tone color creation screen 8a only in the type and screen design of the musical tone parameters presented by the selected tone color type being different. A description of the creation screen 8a ′ is omitted.

  Returning to FIG. 4, when the user selects the “full tone generation function” in step S <b> 2, the process proceeds to the full tone generation function process of (2). In this (2) full timbre creation function process, first, the CPU 5 adds “no selection data” indicating that neither the parameter restriction template nor the screen skin data is selected to the timbre data (step S11). Here, “adding non-selection data” to timbre data is equivalent to storing “non-selection data” in a predetermined area of the edit buffer in the same manner as adding “selection data” to timbre data. To do.

  Next, the CPU 5 displays a full tone generation screen on the display 8 (step S12). Then, when the user sets the musical tone parameter presented on the full tone generation screen using the general-purpose physical operation unit, the CPU 5 changes the value of the corresponding musical tone parameter in the edit buffer according to the user's operation. Set (step S13). In addition, since each process of said step S12 and S13 should just apply the process currently performed with the said conventional electronic music apparatus (the said music synthesizer) as it is not the characteristic of this invention, the description is abbreviate | omitted.

  When the (1) type-by-type tone color creation function processing is completed, or during the process, the CPU 5 checks whether or not the “save” button in the type-by-type tone color creation screen has been operated (step S9). When the “button” is operated, the process proceeds to the storage process (4). In this (4) saving process, the CPU 5 stores the timbre data in the edit buffer in the storage device 9. Naturally, “selected data” is also added to the timbre data and stored in the storage device 9.

  On the other hand, if the “save” button is not operated, the CPU 5 checks whether or not the “full” button in the tone generation screen for each type has been operated (step S16), and if the “full” button is operated, Is advanced to the mutual transfer process (3). In the (3) mutual transition process, the CPU 5 advances the process to the middle of the (2) full tone generation function process, that is, the step S12, and performs the subsequent processes. This shifts from “type tone color creation function” to “full tone color creation function”. On the other hand, when the “full” button is not operated in step S16, the CPU 5 returns the process to the process of (1) type tone color creation function, that is, step S8, and creates the (1) type tone color. Continue function processing.

  Further, when the (2) full tone generation function processing is completed or in the middle thereof, the CPU 5 checks whether or not the “save” button has been operated (step S14), and when the “save” button has been operated. Then, the process proceeds to the storing process (4). In this (4) saving process, the CPU 5 stores the timbre data in the edit buffer in the storage device 9. At this time, as a matter of course, “non-selection data” is also added to the timbre data and stored in the storage device 9.

  On the other hand, if the “save” button is not operated, the CPU 5 checks whether or not a “TYPE” button (not shown) in the tone generation screen for each type is operated (step S15), and the “TYPE” button is operated. If so, the process proceeds to the mutual transfer process (3). In this (3) mutual transfer process, the CPU 5 advances the process to the middle of the (1) type-specific tone color creation function process, that is, the step S6, and performs the subsequent processes. As a result, the “full tone generation function” shifts to the “type-specific tone generation function”. The process of step S15 also proceeds when the user newly creates timbre data using the “full timbre creation function”. In this case, when the user operates the “TYPE” button, the CPU 5 shifts the processing from step S15 to step S6 in the flowchart. However, if this transfer is permitted, “non-selection data” is added to the created timbre data, so in step S6 and the next step S7 of the transfer destination, the CPU 5 sets the parameter restriction template and the screen skin data. Cannot be selected. For this reason, in this case, the transition destination from step S15 is changed to step S3 to present timbre type options, which type can be selected, or a message indicating that transition is not possible is displayed, and “full timbre creation” is performed. Leave “Function” selected. In addition to this case, even if the transition from step S15 to step S6 is successful, when the “full tone generation function” is selected, a value outside the setting range is set in the “type tone generation function”. Thereafter, the “sound color creation function for each type” may be selected. In this case, when the type-specific tone color creation screen is displayed, it is only necessary to display that a value outside the setting range is set.

  On the other hand, if the “edit” button is operated as a result of the determination in step S1, the CPU 5 advances the process to step S17. When the process proceeds to step S17, since the user has already selected the timbre data to be edited as described above, the CPU 5 determines whether or not “data with selection” is added to the timbre data. (Step S17).
