Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a patch information setting device for an electronic musical instrument, and more particularly to a technique for facilitating the creation of patch information.

[0002]

2. Description of the Related Art Conventional electronic keyboards, for example, can generate musical tones with various tones. The timbre includes natural musical instrument sounds such as piano, trumpet and wood bass, and electronically created musical instrument sounds such as electronic piano and electric bass. The data for generating these timbres is called patch information and is installed in the electronic keyboard in advance and provided to the user. Further, for example, a synthesizer can also generate musical tones with various tones. However, the synthesizer is designed so that the user can independently create an artificial tone color in addition to the tone color that is previously installed and provided to the user.

In recent years, not only synthesizers but also the above-mentioned electronic keyboards have been developed which are configured so that a user can create a tone color. By the way, the user creating a timbre is specifically equivalent to creating patch data for generating the timbre.

Such an electronic keyboard, synthesizer, etc. (hereinafter collectively referred to as "electronic musical instrument") has a preset area, a user area and a work area as shown in a part of FIG. The preset area is composed of, for example, a read-only memory (hereinafter referred to as “ROM”), and patch data is stored as preset data. This preset data is generally supplied from the manufacturer. The user area is composed of a random access memory (hereinafter referred to as “RAM”) having a fixed capacity, and is used to store the patch data created by the user. This user area has a nonvolatile memory (for example, EPROM, battery-backed RA, etc.) so that its contents will not be lost even when the power is cut off.
M) and the like. The work memory is composed of RAM and is used as a work area for the user to create patch data.

Further, such an electronic musical instrument has an operation mode called an edit mode, and the patch data is
It is created by the user operating a predetermined operator provided on the operation panel, for example, in this edit mode.

That is, first, the electronic musical instrument is set to the edit mode.
Then, one patch data is selected from the preset area and loaded into the work memory. Then, the patch data is changed on this work memory to create new patch data corresponding to a desired tone color. Then
The patch data created on the work memory is stored in the user area. This completes the creation of patch data. The patch information created in this way is selected by, for example, a patch data selection switch provided on the operation panel and used for actual sounding.

[0007]

In the above-described conventional electronic musical instrument, the size of the user area is constant, so the number of patch data that can be stored is limited. Therefore, when the size of the unused area of the user area (hereinafter referred to as "remaining capacity") is smaller than the new patch data created in the work area, the new patch data cannot be stored in the user area. .

Therefore, in the conventional electronic musical instrument, the user
There is a problem that it is inferior in usability because it is necessary to keep track of the remaining capacity. Also, when the user tries to store the contents of the work area in the user area, even though the remaining capacity is smaller than the new patch data created in the work area, a memory full message is displayed,
No store operation is performed. When this happens,
There is no choice but to discard the patch data created by the user.

Therefore, an object of the present invention is to easily recognize the remaining capacity of the memory that stores patch data.
An object of the present invention is to provide a patch information setting device for an electronic musical instrument, which has excellent operability.

[0010]

In order to achieve the above object, the patch information setting device for an electronic musical instrument according to the first aspect of the present invention has a storage means for storing patch information for defining a tone color. In the patch information setting device of the electronic musical instrument, which uses the patch information created by the user as the storage means, the calculation means calculates the size of the unused area of the storage means, and the calculation means calculates the size. Display means for displaying the size of the unused area.

In this case, the display means can be configured to display the size of the unused area calculated by the calculation means in bytes.

According to the first aspect of the invention, since the user can easily know the size of the unused area of the storage means, that is, the remaining capacity , the patch data created by the user is stored in the storage means. It is possible to easily judge whether or not writing is possible. Therefore, unlike the conventional case, it is not necessary to always grasp the size of the unused area of the storage means, and the patch data can be easily created.

Further, the patch information setting apparatus for an electronic musical instrument according to the second aspect of the present invention has a plurality of types of patch information of different sizes, which are patch information for defining a tone color for the same purpose as described above. A patch information setting device for an electronic musical instrument, comprising a storage unit for storing information, and storing patch information of each type created by a user in the storage unit,
Based on the size of the unused area of the storage means, the number of pieces of patch information that can be stored in the storage means is calculated for each type, and the number of pieces of storable patch information calculated by the calculation means is typed. Display means for displaying each of them.

According to the second aspect of the invention, the display means shows how many or not the patch data can be stored in the storage means. Therefore, the user does not need to know the size of the patch data created by himself, nor is it necessary to always know the size of the unused area of the storage means as in the conventional case.

The patch information setting device for an electronic musical instrument according to the second aspect of the present invention further comprises a display instructing means, and the display means is capable of storing the information when there is an instruction from the display instructing means. It can be configured to display the number of patch information. With this configuration, the user can know the number of patch data items that can be stored in the storage unit by operating the display instruction unit as necessary, and can display other information in other cases. Means can be used effectively.

Further, the display means can be configured to specially display the number of the patch information corresponding to the type of patch information created by the user. As the special display, reverse display, blink display, display with an underline can be used. According to this configuration, not only the number of patch data that can be stored in the storage means but also the type of patch data currently created by the user can be known.

[0017]

In the normal performance mode, selection of patch data, that is, selection of tone color and normal performance are performed. In the edit mode, patch data is changed (edited). In the writing mode, the patch data created by the user is written in the storage means.

In the present embodiment, in order to simplify the explanation, it is assumed that 10 patch data are stored in the preset area, and the patch data created by the user is 1
Up to 0 can be stored in the user area. However, the number of patch data stored in the preset area and the user area is not limited to these, and may be any number.

As shown in FIG. 3, each patch data is composed of a common section CMN and a source section SC following it. The common portion CMN has a fixed size and stores information common to each patch data. For example, in this common part CMN, the name, size, and
The type and other various parameters are stored. Also,
The source part SC is composed of a plurality of blocks, and each block has a certain size. Information regarding the waveform is stored in each block. The type of patch data is determined by the number of blocks forming the source part. It should be noted that, in FIG. 3, as an example, a "type 1" including one common part CMN and a source part SC having two blocks and a source part SC having one common part CMN and three blocks are shown.

This user area is an area for storing patch data created by the user, and is configured to store up to 10 pieces of patch data.

Further, the RAM 12 is provided with a work area, a patch area address table, a patch area pointer, a patch number register, etc., as shown in FIG. The work area stores the patch data read from the patch area. In the normal performance mode, the tone color is controlled according to the contents of this work area. On the other hand, in the edit mode, this work area is used to edit the patch data. That is, the user creates desired patch data in the work area and writes it in the patch area (user area). The patch data is normally created by reading desired patch data from the patch area to the work area, making a change to the patch area, and writing the patch data again in the patch area.

The patch area address table stores the start address of each patch data in the patch area.
Therefore, this patch area address table contains 20
Individual addresses are stored. The patch area pointer is

The user area, the patch area address table and the patch area pointer are composed of a non-volatile memory so that the stored contents can be held even after the power is turned on. As this non-volatile memory,
For example, battery-backed RAM, EPRO
It can be composed of M and the like. Areas of RAM12 other than the above are:
Although it is composed of an ordinary volatile memory, it may be composed of a non-volatile memory.

In addition to the above, the RAM 12 has a CP
The U10 is provided with registers, counters, flags, and the like used in the course of various processes, which will be described below as needed.

In FIG. 1, the keyboard 13 has a plurality of keys, and each key is provided with two key switches. The keyboard 13 detects the opening / closing of the key switch of each key, generates key data indicating the presence / absence of key depression and key release based on the detection result, and also generates touch data indicating the strength of key touch. It The key data and the touch data are supplied to the CPU 10.

On the operation panel 14, as shown in FIG.
A plurality of operators and a display device 50 are provided. The operation panel 14 detects the operation state of each operator,
Panel data is generated based on this detection result. This panel data is supplied to the CPU 10.

The edit switch E of the plurality of operators described above.
The DIT is used to shift the operation mode of this electronic musical instrument to the edit mode. This edit switch EDIT
Each time is pressed, the edit mode and the normal performance mode are switched alternately. Whether the current editing mode or the normal performance mode is set is stored by the editing flag provided in the RAM 12.

The write switch WRITE is an operator for instructing setting of the write mode and cancellation of the write mode. The write mode is an operation mode for storing the edited patch data (changed) in the user memory. Whether or not it is in the write mode depends on R
It is stored by the write flag provided in the AM 12.

The numerical value input switch 23 is composed of +10 switch, -10 switch, +1 switch and -1 switch. The +10 switch increases the value by 10 units, the -10 switch decreases the value by 10 units, and +1
The switches are used to increase the value by 1 unit, and the -1 switch is used to decrease the value by 1 unit. Each of these switches is used to set the volume and the depth of effect in the normal performance mode. On the other hand, in the edit mode, it is used as an operator for changing the value of each patch data.

The patch data selection switch 24 is composed of, for example, 20 push button switches P1 to P20. In the normal performance mode, these switches P1 to P20 are used to select one patch data to be used for performance from the 20 types of patch data stored in the patch area. In the edit mode, from the 20 types of patch data stored in the patch area,
Used to select one patch data to load into working memory. Further, in the write mode, it is used to specify the patch number assigned to the patch data created by the user.

The display device 50 is used to display various messages. The display device 50 is composed of, for example, an LCD, and is configured to display characters, numbers, symbols, figures and the like.
For example, the display device 50 displays the remaining capacity of the user area when entering the edit mode.

In FIG. 1, the tone signal generator 15 is
It is equipped with multiple tone generation channels and is configured to generate multiple musical tones simultaneously. The tone signal generator 15 generates a digital tone signal based on the key data and touch data generated by the keyboard 13 and the patch data supplied from the work memory.

The digital tone signal generated by the tone signal generator 15 is supplied to the D / A converter 16. D /
The A converter 16 converts the digital musical tone signal from the musical tone signal generator 15 into an analog musical tone signal and supplies it to the amplifier 17. The amplifier 17 amplifies the analog musical tone signal from the D / A converter 16 and supplies it to the speaker 18. As a result, a musical sound is generated from the speaker 18.

Next, a main operation procedure for operating the patch information setting device to exert a predetermined function will be described.

First, an operation procedure for selecting desired patch data to generate a musical tone will be described. In this case, first, the edit switch EDIT is operated to put the electronic musical instrument in the normal performance mode. Then, the switches P1 and P2
By operating any of the switches 0, the patch data to be used for the performance is selected. By this, one selected patch data is loaded into the work memory. When the keyboard 13 is operated in this state, a musical tone is generated with a tone color corresponding to the patch data loaded in this work memory.

Next, an operation procedure for editing the patch data will be described. In this case, first, the edit switch EDIT is operated to put the electronic musical instrument in the edit mode. Then, in this edit mode, the switches P1 to P20
The patch data to be changed is selected by operating any of the switches. 1 selected by this
One patch data is loaded into the work memory. Then, the numerical input switch 23 is operated to change the patch data in the work memory to a desired value. When the keyboard 13 is operated in this state, a musical tone is generated with a tone color corresponding to the patch data in this work memory. Therefore, the user can change the patch data while checking the timbre.

Next, the procedure for storing the edited patch data in the patch area will be described. In this case, first, the write switch WRITE is operated to enter the write mode. Next, in this writing mode, by operating any of the switches P1 to P20, the patch number associated with the patch data in the work memory is selected. As a result, the patch data in the work memory is stored at the beginning of the unused area of the user memory.

Next, the operation of the electronic musical instrument to which this patch information setting device is applied will be described with reference to the flow charts of FIGS. Note that the processes shown in these flowcharts are processes performed by the CPU 10.

(1) Main Processing FIG. 6 is a flowchart showing the main processing. When the power of the electronic musical instrument is turned on, the CPU 10 first performs initial processing (step S10). In this initial processing, initialization of the tone signal generator (sound source) 15 and RA
The predetermined area of M12 is cleared and the like. RAM
Of the 12 areas, the user area, the patch area address table, and the patch area pointer, which are configured by the non-volatile memory, are not initialized and retain the original data.

Next, a key scan process is performed (step S11). In this key scan process, key data and touch data are fetched from the keyboard 13.
Then, it is checked whether or not there is a key event, that is, whether or not there is an operated key (step S12). If it is determined that there is a key event, key processing is performed (step S13).

In the key processing, first, it is checked whether or not the key event is a key-on event, and if it is determined that it is a key-on event, the key-on processing is performed. In this key-on processing, key data and touch data obtained from the keyboard 13 and patch data stored in the work area are supplied to the musical tone signal generator 15 in order to generate a musical tone in response to a key operation. .
The musical tone signal generator 15 generates a digital musical tone signal based on these data. This digital tone signal is
As described above, the D / A converter 16 converts the signal into an analog tone signal, which is then amplified by the amplifier 17 and then sent to the speaker 18. Thereby, from the speaker 18,
A sound corresponding to the pressed key is generated.

On the other hand, when it is determined that the key event is the key-off event, the key-off process is performed. In this key-off process, the predetermined data is the tone signal generator 1
5 is supplied. As a result, the sound corresponding to the released key is muted.

When the above key processing is completed or it is determined in step S12 that there is no key event, then panel scan processing is performed (step S14).
In this panel scan process, panel data is fetched from the operation panel 14. Then, it is checked whether or not there is a panel event, that is, whether or not there is an operated operator (step S15). If it is determined that there is an operator event, panel processing is performed (step S16). Details of this panel processing will be described later.

When the panel processing is completed or it is determined in step S15 that there is no panel event, then "other processing" is performed (step S1).
7). In this "other processing", for example, M (not shown)
M with external device via IDI interface circuit
A process of transmitting and receiving IDI data is performed. afterwards,
Returning to step S11, the same processing is repeated thereafter.

As described above, when the panel operation or the key operation is performed in the process of repeatedly executing the above steps S11 to S17 of the main processing routine, the process corresponding to the operation is performed, thereby the patch information setting device and the electronic device. Various functions as musical instruments have been realized.

(2) Panel Process Next, the panel process performed in step S16 of the main process will be described. FIG. 7 is a flowchart showing the overall processing of the panel processing, and FIGS. 8 to 11 are flowcharts showing the details of the processing for each switch executed as a subroutine. The details of the panel processing will be described below with reference to these flowcharts.

(2-1) Overall Processing FIG. 7 is a flowchart showing the overall processing of panel processing. In this whole process, first, the edit switch EDIT
It is checked whether or not there is an on event (step S20). Whether or not there is an ON event of the edit switch EDIT indicates that the bit corresponding to the edit switch EDIT in the panel data obtained by the previous panel scan processing is OFF, and the panel data obtained by the panel scan processing this time. This is done by checking whether the bit corresponding to the edit switch EDIT in the inside indicates ON. The same applies to the other switches.

In step S20, the edit switch ED
If it is determined that there is an IT on-event, edit switch processing is performed (step S21), and if not, this edit switch processing is skipped. Then, it is checked whether or not there is an on event of the write switch WRITE (step S22). Here, if it is determined that there is an on event of the write switch WRITE, write switch processing is performed (step S23),
Otherwise, this write switch process is skipped. Then, it is checked whether or not there is an on event of any of the switches P1 to P20 forming the patch data selection switch 24 (step S24).

If it is determined that there is an on event of any of the switches P1 to P20, the patch data selection switch processing is performed (step S25). If not, this patch data selection is performed. The switch process is skipped. Next, the numerical input switch 2
It is checked whether or not there is an ON event of any one of the +1 switch, −1 switch, +10 switch and −10 switch in 3 (step S26). If it is determined that there is an on event of any of these switches, the numerical value input switch process is performed (step S2).
7) After that, the sequence returns to the main processing routine. When it is determined in step S26 that there is no on event of the numerical value input switch 23, the sequence returns to the main processing routine.

(2-2) Edit Switch Process FIG. 8 is a flow chart showing the edit switch process executed when the edit switch EDIT is operated.

In this edit switch process, first,
It is checked whether or not the edit mode is currently set (step S).
30). This is done by looking at the edit flags,
The same applies below. If it is determined that the edit mode is not set, that is, the normal performance mode is set, the edit mode is set (step S31). Specifically, the edit flag is set to "1". Then, the remaining capacity of the user area in the patch area is displayed on the display device 50 (step S32). This remaining capacity can be displayed in the following form, for example.

In the first display mode, the remaining capacity is displayed in bytes on a part of the display device 50, as shown in FIG. 5 (A), for example. In this case, the remaining capacity can be obtained by subtracting the address indicated by the patch pointer from the address next to the last address in the user area. According to the first display mode, the user can know whether the patch data to be created can be stored in the user area when the patch data used for editing is loaded in the work area. Therefore, since it is possible to know whether or not the user area will be full before starting the editing operation, there occurs a situation in which the patch data cannot be stored in the patch area after the patch data is created, as in the conventional case. Can be prevented.

In the second display mode, for example, as shown in FIG.
The number of patch data that can be stored in the user area is displayed for each type. In the example of FIG. 5B, the user area is
Three types of patch data (CMN1SC) having one common part CMN and one block source part SC (CMN1SC) have three common patch data (CMN1SC) and one block part source part SC (CMN1SC)
2SC) indicates that two pieces can be stored, and one piece can store one common section CMN and one piece of patch data (CMN3SC) of a type having a source section SC composed of three blocks. According to the second display mode, the user can easily know whether or not the patch data can be stored in the user area if the user knows only the type of patch data to be created, so that the operability is improved. .

The hatched portion in FIG. 5 (B) is a portion for reverse display as a special display,
It represents the type of patch data currently loaded in work memory. As a result, the user can know the type of patch data to be edited, so that the operability is further improved.

When the remaining capacity display processing is completed, the sequence returns to the overall processing routine. As a result, the remaining capacity is displayed on a part or all of the display device 50 during the edit mode.

When it is determined in step S30 that the edit mode is set, the edit mode is released (step S33). Specifically, the edit flag is cleared to "0". Then, the display device 50
The remaining capacity display above is erased (step S34). After that, the sequence returns to the overall processing routine.

With the above processing, the edit switch EDIT
Every time the button is pressed, an edit mode and a mode other than that (normal performance mode) are alternately set, and when the edit mode is entered, the function of displaying the remaining capacity on the display device 50 is realized.

(2-3) Write Switch Process FIG. 9 is a flow chart showing the write switch process executed when the write switch WRITE is operated.

In this write switch process, it is first checked whether the write mode is set (step S40). This is done by examining the write flag, and so on. Then, when it is determined that the writing mode is not set, a process of setting the writing mode is performed (step S41). Specifically, the write flag is set to "1". After that, the sequence returns to the overall processing routine.

When it is determined in the above step S40 that the writing mode is set, the processing for canceling the writing mode is performed (step S42). Specifically, the write flag is cleared to "0". After that, the sequence returns to the overall processing routine.

By the above processing, the write switch WRI
The function of alternately setting the write mode and the non-write mode each time TE is pressed is realized.

(2-4) Patch Data Selection Switch Process FIG. 10 shows a patch data selection switch process executed when any of the switches P1 to P20 included in the patch data selection switch 23 is operated. It is a flowchart shown.

In this patch data selection switch process, it is first checked whether or not the write mode is set (step S50). If it is determined that the writing mode is not set, then it is checked whether or not the editing mode is set (step S51). Here, if it is determined that the edit mode is not set, that is, the normal play mode,
The patch data corresponding to the pressed switch among the switches P1 to P20 is loaded into the work memory (step S52). This process will be described with reference to FIG. First, the patch number corresponding to the pressed switch among the switches P1 to P20 is stored in the patch number register. And in the patch area address table,
One address is taken out from the position designated by this patch number, and one patch data is read from the patch area designated by the address. The read patch data is loaded into the work memory.

Next, the contents of the work memory are sent to the tone signal generator 15 (step S53). After that, the sequence returns to the overall processing routine. As a result, the tone color generated by the electronic musical instrument is determined. Therefore,
When the keyboard 13 is operated thereafter, a musical tone is generated with a tone color according to the patch data loaded in the work memory.

When it is determined in step S51 that the edit mode is set, the patch data corresponding to the pressed switch among the switches P1 to P20 is loaded into the work memory (step S54). This process is the same as the process of step S52 described above. After that, the sequence returns to the overall processing routine. The user changes the contents of the patch data loaded in the work memory using the numerical value input switch 23 to generate new patch data corresponding to a desired timbre. The patch data changing process according to the operation of the numerical value input switch 23 is performed by a numerical value input switch process described later.

When it is determined in the above step S50 that the writing mode is set, the process of writing the contents of the work memory into the user area is performed (step S55). This process will be described with reference to FIG. First, the patch number corresponding to the pressed switch among the switches P1 to P20 is stored in the patch number register. Then
The contents of the patch area pointer are written in the position designated by the patch number in the patch area address table. Next, the contents of the work memory are written in the position pointed to by the patch area pointer in the patch area address table. Next, the contents of the patch area pointer are updated. After that, the sequence returns to the overall processing routine. Through the above processing, the switches P1 and P2
The patch data created in the work memory is associated with the pressed switch in 0.

(2-5) Numerical value input switch process FIG. 11 is a flowchart showing a numerical value input switch process executed when the numerical value input switch 23 is operated.

In this numerical value input switch process, it is first checked whether or not the edit mode is set (step S60). When it is determined that the edit mode is set, the patch data is changed (step S6).
1). That is, a part or all of the patch data loaded in the work memory is replaced with the numerical value input by the numerical value input switch 23.

Then, it is checked whether the type of patch data has been changed (step S62). this is,
This is performed by checking whether the data representing the type included in the common part CMN has been changed. When it is determined that the type has been changed, the remaining capacity is displayed (step S63). The content of this process is the same as the process of step S32 described above. On the other hand, if it is determined in step S61 that the type is not changed, the process of step S62 is skipped. After that, the sequence returns to the overall processing routine.

By the above processing, when the user changes the patch data type and the size of the patch data increases or decreases, the remaining capacity displayed on the display device 50 is changed to the latest remaining capacity. Can easily determine whether the changed patch data can be stored in the user area.

If it is determined in step S60 that the edit mode is not set, "other processing" is performed (step S64). In this "other processing", for example, a sound volume changing processing, an effect depth changing processing, and the like accompanying the operation of the numerical input switch 23 are performed. After that, the sequence returns to the overall processing routine.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment,
Various modifications can be made based on the technical idea of the present invention.
For example, the format of each patch data is not limited to the above, and may be any format as long as the size of each type of patch data can be recognized.

In the above-described embodiment, the number of patch data that can be stored in the user area is displayed by type as the second display mode. However, all of the types of this type are simultaneously displayed on the display device 50. If it cannot be displayed on the screen, it can be configured to scroll the screen. With this configuration, the present invention can be applied to a patch information setting device having many types.

It is also possible to provide a switch for instructing the display of the remaining capacity and display the remaining capacity only when the switch is pressed. According to this configuration, even when the display screen of the display device 50 is small, the remaining capacity can be displayed only when the user needs it, so that the display device can be effectively utilized.

Further, in the above embodiment, when the remaining capacity is displayed in the second display mode and the number of patch data that can be stored is smaller than “1”, the remaining capacity is stored in the current work memory. It can be configured to display the ratio (for example, a percentage) to the size of the stored patch data.

Further, in the above-described embodiment, the patch data created by the user is configured to be sequentially stored in the unused area of the user area, but it may be configured to overwrite the already written area. . In this case, the fact can be displayed on the display device 50.
