Descriptions related to voicesTones that can be used in electronic musical instruments include various types of sounds, such as so-called instrument sounds that mimic the sound of existing instruments such as pianos and violins, and sounds that can be arbitrarily set or changed by the player. There is a tone. In this embodiment, the latter tone is referred to as a voice. However, there is no point in eliminating voices such as musical instrument timbres in the voice. That is, a certain voice may imitate a musical instrument tone like a piano if it is a piano. In this embodiment, the following description will be made assuming that a tone refers to a voice. However, in the electronic musical instrument as a whole, in addition to such a voice, a musical instrument tone or some preset tone can be further selected. Even if there is no problem. In this embodiment, a musical tone signal corresponding to one voice is generated by synthesizing musical instrument signals generated in a plurality of streams. In this case,
Each series of tone signals or their timbres, which are components of one voice, are referred to as elements or element timbres. In that sense, the voice in this embodiment may be said to be a “composite tone” in which a plurality of element tones are combined.

Next, an example of the memory format of the voice data memory VDM and the voice edit buffer memory VEB will be described with reference to FIG.

The voice data memory VDM stores, for each voice, voice data for realizing the voice. The voice edit buffer memory VEB is a buffer for storing voice data of a voice being edited.
These voice data memory VDM and voice edit buffer memory VEB consist of readable and writable memory,
For example, a part of the data and working RAM 12 (FIG. 2) is used.

The voice data memory VDM has a voice data area for storing voice data for each voice identified by voice numbers 0 to n. The head address of each voice data area is indicated by a voice pointer VOICEP.

One voice data area includes an area for storing “voice name”, an area for storing “voice mode”,
It comprises an area for storing “common data” and four “element parameter data” areas for storing parameter data corresponding to four individual elements.

In this embodiment, one voice can be synthesized using up to four elements. One element corresponds to one sequence of tone signals generated by the PCM sound source 17 or the FM sound source 18 using one channel. The types of parameter data for realizing a desired tone (element tone) are different between the PCM sound source 17 and the FM sound source 18, and the data contents are also different for each element tone. On the other hand, there is parameter data common to all element tones. As described above, parameter data common to all elements in the voice is also referred to as “common data”, and is stored in the “common data” area. On the other hand, parameter data different for each element is referred to as “element parameter data”, and is stored in an “element parameter data” area corresponding to each element. The start address of each "element parameter data" area is the element start pointer ESP (1) to ESP
Indicated by (4). Elements indicated by the element start pointers ESP (1) to ESP (4) are distinguished as elements 1 to 4, respectively.

The “voice mode” mainly indicates a combination of the type of the sound source used to realize the voice and the number of streams. “Voice mode data” for indicating which of a plurality of predetermined voice modes is selected is stored in the “voice mode” area. As will be described later, it is determined whether each of the four elements uses the PCM sound source or the FM sound source, or whether neither of them uses the “voice mode”.

The voice edit buffer memory VEB has a capacity capable of storing a set of voice data of one voice, and specifically includes a common data buffer CDB, an FM edit buffer FMEB, and a PCM edit buffer PCMEB. The common data buffer CDB has an area for storing “voice name”, an area for storing “voice mode”, and an area for storing “common data”. FM
The edit buffer FMEB has FM element edit buffers 1 to 4 which can store parameter data of four elements, respectively. PCM edit buffer P
CMEB also has PCM element edit buffers 1 to 4 which can store parameter data of four elements, respectively.

The reason why edit buffers FMEB and PCMEB corresponding to different sound sources are provided for each of the maximum number of elements is to enable immediate response even when the voice mode is changed during editing. For example, if you use an FM sound source with two elements and another two elements
When editing a voice in the voice mode using the PCM sound source, first, voice data of the voice is copied from the voice mode memory VDM to the voice edit buffer memory VEB. In this case, the method of copying is to copy the "voice name", "voice mode" and "common data" to the common data buffer CDB, and the parameter data of the two elements corresponding to the FM sound source to the two in the FM edit buffer FMEB. The data is copied to the FM element edit buffers 1 and 2, and the parameter data of the two elements corresponding to the PCM sound source are stored in the PCM edit buffer PCMEB.
Are copied to the two PCM element edit buffers 1 and 2. Then, the remaining two FM element edit buffers 3 and 4, which have not been copied,
Predetermined initial values (or reference values) of “element parameter data” for the FM sound source are stored. Similarly, predetermined initial values (or reference values) of the “element parameter data” for the PCM sound source are stored in the remaining two PCM element edit buffers 3 and 4 that have not been copied. If you do this,
By changing the voice mode data stored in the common data buffer CDB during the editing operation, for example, when the voice mode is changed to a mode in which all four elements are FM sound sources (or PCM sound sources), four FM element edit buffers 1 are used. To 4 (or PCM element edit buffers 1 to 4) can be used immediately and effectively. That is, if the total number of element edit buffers is limited to the maximum number of elements of 4, only in the case of the above example, the data content of the element edit buffer must be changed from PCM data to FM data (or vice versa). Is troublesome. However, according to this embodiment, there is no such trouble.

The start address of each of the maximum four element edit buffers in use among the total eight element edit buffers is an edit start pointer.
Indicated by EDS (1) to EDS (4).

Description of Voice Mode Next, the “voice mode” will be described. In this embodiment, there are ten voice modes. Voice mode is
The combination of the type of sound source to be used and the number of series are mainly defined, and furthermore, the distinction between single sound / multiple sound and, in the case of multiple sound, the number of simultaneous sounds are defined. The combination of the type of sound source to be used and the number of streams is based on whether the sound source used in the four elements 1 to 4 is PCM or FM, or whether this element is not used.
Can be defined. This is defined by data called "element type". There are three types of "element types", 0, 1, and 2, and the contents of each are as follows.

Element type 0: Not used Element type 1: Uses FM sound source Element type 2: Uses PCM sound source The four element types 1 to 4 in each voice mode have the contents shown in FIG. It is stored in advance in the type table ETT.
The element type table ETT also stores data indicating the number of simultaneous possible sounds. In other words, the substantially simultaneous possible number of sounds is a maximum value at which musical tone signals of different pressed keys can be simultaneously generated.

The voice modes 1 to 3 are voices in the monophonic sound generation mode, and the number of possible simultaneous sounds is one.

In voice mode 1, element 1 is element type 1, that is, an FM sound source, and other elements 2 to 4 are element type 0, that is, are not used. Therefore, it is a single-tone voice composed of element tones of the FM sound source.

In voice mode 2, elements 1 and 2 are element type 1, that is, FM sound source, and other elements 3, 4 are element type 0, that is, not used. Accordingly, it is a voice of two series of single tones composed of element tone colors of the FM sound source (in the case of two series, a tone related to the same pressed key is generated in two channels).

In the voice mode 3, all the elements 1 to 4 are the element type 1, that is, the FM sound source. Therefore, the voice is a single tone four-line voice composed of element tone colors of the FM sound source (tones related to the same pressed key are generated on four channels in the four-line sequence).

The voice modes 4 to 10 are voices in the multiple sound generation mode, and the number of simultaneous sounds that can be generated is as described in the table.

In voice mode 4, element 1 is element type 1, that is, FM sound source, and other elements 2 to 4 are element type 0, that is, not used. Therefore, the voice is a series of multiple tones composed of element tone colors of the FM sound source, and the number of simultaneous sounds that can be produced is 16 sounds.

In voice mode 5, elements 1 and 2 are element type 1 or FM sound source, and other elements 3 and 4 are element type 0 or unused. Therefore, it is a voice of two series of double tone composed of element tone of FM sound source,
The number of simultaneous sounds is eight.

In voice mode 6, element 1 is element type 2, that is, a PCM sound source, and other elements 2 to 4 are element type 0, that is, unused. Accordingly, the voice is a series of multiple tones composed of element tones of the PCM sound source, and the number of simultaneous tones is 16.

In the voice mode 7, the elements 1 and 2 are element type 2, that is, a PCM sound source, and the other elements 3, 4 are element type 0, that is, are not used. Therefore, it is a two-voice series of double tone composed of element tone colors of the PCM sound source, and the number of simultaneous tones is eight.

In the voice mode 8, all the elements 1 to 4 are element type 2, that is, PCM sound sources. Therefore, it is a voice of four series of multiple tones composed of the element timbres of the PCM sound source, and the number of simultaneous tones is four.

In voice mode 9, element 1 is element type 1, that is, FM sound source, element 2 is element type 2
That is, it is a PCM sound source, and the other elements 3 and 4 are element type 0, that is, unused. Therefore, it is a double tone two-series voice composed of a combination of the element tone of the PCM tone generator and the element tone of the FM tone generator, and the number of simultaneous tones is 16 tones.

In the voice mode 10, the elements 1 and 2 are element type 1 or FM sound source, and the elements 3 and 4 are element type 2 or PCM sound source. Therefore, it is a voice of four series of multiple sounds composed of a combination of two series of PCM sound source and two series of FM sound source, and the number of simultaneous sounds is eight.

Description Related to Processing by Microcomputer FIG. 10 exemplifies data and main data stored in registers in the working RMA 12, and their roles will be clarified later according to the description of the flowchart.

FIG. 11 shows an example of the contents of the entry point table EPT. The entry point table EPT is a table that indicates a routine to be executed next according to an ON event of the switch, in accordance with a correspondence between a display screen (page) on the display unit DPY and an ON switch on the operation panel 15.

Next, an example of processing executed by the microcomputer will be described with reference to the flowcharts in FIG. 12 and subsequent figures.

FIG. 12 shows an example of the main routine.
At power-on, a predetermined initialization process is performed to initialize the contents of each register and memory. Next, in the "key scan and assignment process", each key switch in the keyboard circuit 14 is scanned to detect on / off thereof, and a process of assigning a pressed key to any of a plurality of sound channels is performed.
One of the processes executed in the "key scan and allocation process" is a "key-on event process", an example of which is shown in FIGS. 25 and 26, and will be described in detail later. In this "key-on event process", when a key is newly pressed, generation of a tone signal corresponding to the key is performed.
A process of allocating to the channels of the PCM sound source 17 and / or the FM sound source 18 is performed.

In the "performance controller processing", the performance controller 16
Is detected, and a predetermined process is performed when the operation state changes.

In the "function switch processing", the on event (change from off to on) of the function switch unit FSW is detected, and if the on event is detected,
A function switch on event routine as shown in FIG. 13 is performed.

In the “other panel scanning process”, other operators and key switches on the operation panel 15 are scanned to detect on / off thereof, and various processes are performed based on the detection. One example is a key switch turned on and a display
Referring to the entry point table EPT in FIG. 11 according to the current page of the DPY, a switch-on event subroutine as shown in FIGS. 14 to 24 is called.

How to read the entry point table EPT In the entry point table EPT in FIG. 11, the vertical column indicates an ON event of each key or switch, and the horizontal column indicates a page of the display unit DPY at the time of the switch ON event. The symbol written at the intersection of the vertical column and the horizontal column indicates the subroutine to be called (that is, the entry point of the subroutine). Each subroutine will be described later. Here, the symbol “NoEP” means “no entry point” and indicates that there is no subroutine to be called (that is, no entry point).

Processing at the time of function switch operation When any of the function switches F1 to F8 is turned on, the function switch on event routine of FIG. 13 is performed. Here, first, the number of the function switch that has been turned on is stored in the function switch buffer FSWBUF, and then the function switch buffer FSWBUF and the current page PAGE refer to the entry point table EPT in FIG. The entry point data of a predetermined event processing subroutine assigned to the function switch is obtained and stored in the entry point buffer EPBUF. Then, after confirming that the contents of the entry point buffer EPBUF are not the no entry point NoEP, an event processing subroutine corresponding to the contents of the entry point buffer EPBUF is called. In addition,
The current page PAGE indicates the current display page of the display unit DPY.

Voice Selection In this electronic musical instrument, a voice number indicating one voice currently selected for sound generation or editing operation is stored in a predetermined register, that is, a voice number register. The voice number stored in the voice number register is indicated by VN. This voice number
By referring to the VN, it is possible to know which voice is currently selected.

Selection of a desired voice is performed by calling up a “voice selection” page as illustrated in FIG. 27 on the display unit DPY. When the display screen of the display unit DPY is a page other than “voice selection”, pressing the voice key VOICE (FIG. 7) calls up the “voice selection subroutine” EPV in the entry point table EPT (FIG. 11), and Selection becomes possible.

The voice selection subroutine EPV will be described with reference to FIG. 14. First, the content of the current page PAGE indicating the page of the display unit DPY is set to "1" indicating the "voice selection" page (step 50). .

Next, the screen display of the display unit DPY is changed to a “voice selection” page as illustrated in FIG. 27, the voice name of each selectable voice is displayed together with the voice number, and the cursor is indicated by the voice number VN. "Step 51" to place at the position of a specific voice.

Next, a voice data pointer VOICEP for reading the voice data memory VDM (FIG. 8) is set to a value corresponding to the current voice number VN (step 52).

Next, the voice mode data is read from the voice data area designated by the voice data pointer VOICEP, and is set in the voice mode register VMODE.
That is, VMODE indicates the voice mode of the currently selected voice. Also, element start pointer ESP
(1) to ESP (4) are set to values corresponding to the four "element parameter data" areas in the voice data area specified by the voice data pointer VOICEP (step 53).

Next, referring to the element type table ETT (FIG. 9) according to the contents of the voice mode register VMODE, the number of simultaneous sounds that can be performed in the voice mode (the value in the column of the number of simultaneous sounds in the element type table ETT) is determined. And
This is stored in the simultaneous soundable number register NSCH (step 54).

In the state where the “voice selection” page as illustrated in FIG. 27 is displayed on the display unit DPY in this manner, next,
When the data input unit 42 or the cursor key CSR (FIG. 7) is operated, the voice number VN is changed accordingly, and a desired voice can be selected.

To explain this point, when the data input section 42 is operated while the "voice selection" page is displayed, the "voice selection numerical value input subroutine" EPDS (1) is called in the entry point table EPT (FIG. 11). . When the cursor key CSR is operated while the "voice selection" page is displayed, the "voice selection cursor key on event subroutine" EPCD (1) is called in the entry point table EPT (FIG. 11).
Note that there are two types of cursor keys CSR, a vertical cursor and a horizontal cursor, and their processing contents are slightly different. However, for convenience of explanation, it is assumed that there is one cursor key CSR.

Voice selection numerical input subroutine EPDS (1) and voice selection cursor key on event subroutine EPCD (1)
Referring to FIG. 15, first, when the data input unit 42 is operated, the voice number VN is changed according to the numerical value input by the data input unit 42 (step 55).

Next, the position of the cursor on the display unit DPY is moved to the position of the specific voice indicated by the new voice number VN (step 56).

The processing in steps 57, 58, and 59 to be performed next is the same as the processing in steps 52, 53, and 54 in FIG. 14, and the voice data pointer VOICEP and the element start pointer ESP (1) correspond to the new voice number VN. ~ ESP (4) settings,
The voice mode VMODE is set, and the simultaneous soundable number register NSCH is set according to the voice mode.

If the cursor key CSR is pressed, the voice number VN
Is incremented by 1 (step 60). This increase is modulo
Perform at 16. The reason for selecting modulo 16 is that the number of selectable voices is set to 16. Then, step 56 described above
5959 are performed.

As is clear from the above, according to the operation of the data input unit 42, a desired voice number can be input at a time,
With the cursor key CSR, a desired voice number is finally input by shifting the voice number VN by one each time the cursor key is pressed.

Introduction to edit processing When performing an editing operation for changing / correcting voice data of a desired voice, first, as described above, a “voice selection” page is called on the display unit DPY, a desired voice is selected, and each register is selected. Contents of VN, VOICEP, VMODE, NSCH, ESP
(1) to ESP (4) are set to contents corresponding to the desired voice. Next, by pressing an edit key EDIT (FIG. 7), the editing process can be started.

When the display screen of the display unit DPY is the “voice selection” page, pressing the edit key EDIT calls up an “edit introduction routine” EPED in the entry point table EPT (FIG. 11). This edit introduction routine
A detailed example of EPED is shown in FIG.

In the edit introduction routine EPED, first, a set of voice data is read from the voice data area corresponding to the voice number VN, and the voice edit buffer VEB (the eighth buffer) is read out.
(Step 61). Thereafter, various editing operations are performed on the voice data stored in the voice edit buffer memory VEB. In other words, the voice edit buffer memory VEB is a dedicated buffer for editing voice data.

The method of copying a set of voice data to the voice edit buffer memory VEB is as described above. That is, "voice name", "voice mode", and "common data" are copied to the common data buffer CDB. In addition, each parameter data corresponding to a maximum of four elements corresponds to one of the four FMs in the FM edit buffer FMEB according to the element type.
Of the four element edit buffers 1 to 4, the ones with the lowest number are sequentially copied, and those corresponding to the PCM sound source are sequentially copied with the lowest number of the four PCM element edit buffers 1 to 4 in the PCM edit buffer PCMEB. make a copy. The remaining initial values (or reference values) of the "element parameter data" for the FM sound source are stored in the remaining FM element edit buffers for which the data has not been copied, and similarly, the data has not been copied. In the remaining PCM element edit buffers, predetermined initial values (or reference values) of “element parameter data” for the PCM sound source are stored.

Next, the value of the voice data pointer VOICEP is set to the start address of the edit buffer memory VEB, and
The values of the edit start pointers EDS (1) to EDS (4) are set to four of four FM element edit buffers 1 to 4 in the FM edit buffer FMEB and four PCM element edit buffers 1 to 4 in the PCM edit buffer PCMEB. The parameter data corresponding to each element is set to the start address of the copied element edit buffer. Therefore, FM
Edit buffer FMEB and PCM edit buffer PCM
Each element 1 related to the voice currently being edited out of a total of eight element edit buffers in the EB
The edit start pointers EDS (1) to EDS (4) that store the parameter data corresponding to
Respectively.

Next, the voice mode data is read from the common data buffer CDB and set to VMODE, and it is checked which of the ten voice modes VMODE is 1 to 10 (see FIG. 9). (Step 63).

If the content of the voice mode VMODE indicates the voice mode 1, 4 or 6 in which only the element 1 is used, step 64 is executed.
To see if the edit mode EMODE is greater than 2.

The edit mode EMODE indicates the content of the editing work at the present time, and takes any value from 0 to 5, and the relationship between the value and the edited content is as follows.

EMODE = 0: Select voice mode EMODE = 1: Edit common data EMODE = 2: Edit data of element 1 EMODE = 3: Edit data of element 2 EMODE = 4: Edit data of element 3 EMODE = 5: Edit element 4 Data editing Therefore, if the edit mode EMODE is greater than 2,
This means that the mode is for editing data of the element 2 or 3, 4 and is unnecessary in the voice mode 1, 4 or 6 using only the element 1. Therefore, if step 64 is YES, the process goes to step 65 and resets the edit mode EMODE to 0.

If the contents of the voice mode VMODE indicate the voice mode 2, 5, 7 or 9 using only the elements 1 and 2, the process goes to step 66 to check whether the edit mode EMODE is larger than 3. When the edit mode EMODE is larger than 3, it means that the mode of editing data of the element 3 or 4 is unnecessary, and is unnecessary in the voice mode 2, 5, 7 or 9 using only the elements 1 and 2. It is. Therefore, if step 66 is YES, step 6
Go to 7 and reset the edit mode EMODE to 0.

If the content of the voice mode VMODE indicates the voice mode 3, 8 or 10 using all the elements 1 to 4, the process goes to step 68 without determining the edit mode EMODE.

In step 68, the value of the edit mode EMODE is 0 to
5 is checked, and an edit introduction subroutine (steps 69 to 74) is executed accordingly.

If the value of the edit mode EMODE is 0, a voice mode selection introduction subroutine VMSSUB is performed. An example of this subroutine VMSSUB is shown in FIG.

First, in step 75, the content of the current page PAGE indicating the page of the display unit DPY is set to a predetermined value nE indicating the “voice mode selection” page.

In the next step 76, the screen display of the display unit DPY is changed to a "voice mode selection" page as illustrated in FIG. The displayed information is displayed, the cursor is placed at the position of the designated voice mode (that is, the currently selected voice mode) indicated by the current voice mode VMODE, and each element 1 to 1 of the currently selected voice mode is displayed. The sound source type of No. 4 is displayed on the upper right (this is called an element configuration display). In addition, "MODE", "COM", "E1", "E2", "E3", "E4" are displayed as displays corresponding to the function switches F1 to F5.
Is displayed to indicate that the function of each of the function switches F1 to F5 is an edit mode selection function. "MO
"DE" indicates voice mode selection, "COM" indicates common data edit, and "E1" to "E4" indicate edit modes for editing data of elements 1 to 4, respectively. In this function switch display, the current edit mode (voice mode selection MOD in this example)
E) is displayed normally, and the other edit modes are displayed in white to indicate that those edit modes can be selected by operating the function switch.

Note that the process of setting the screen display of the display unit DPY to the “voice mode selection” page as illustrated in FIG. 28 is performed not only by the above-described voice mode selection introduction subroutine VMSSUB but also by the voice mode selection subroutine EPVM. Good. That is, in the edit mode pages other than the voice mode selection page, as described above, the voice mode selection is assigned to the function switch F1, and these edit mode pages are displayed on the display unit DPY. When the function switch F1 is turned on when the
In T (Fig. 11), "Voice mode selection subroutine" EPV
Call M.

This voice mode selection subroutine EPVM is shown together with the voice mode selection introduction subroutine VMSSUB in FIG. First, in step 77, the edit mode EMODE is set to "0" indicating "voice mode selection", and then the processing in steps 75 and 76 is performed.

In the state where the “voice mode selection” page as illustrated in FIG. 28 is displayed on the display unit DPY in this manner,
Next, when the data input section 42 or the cursor key CSR is operated, the value of the voice mode VMODE is changed accordingly, and a desired voice mode can be selected.

To explain this point, when the data input unit 42 is operated in a state where the “voice mode selection” page is displayed, the “voice mode selection numerical value input subroutine” EPDS (nE) is displayed in the entry point table EPT (FIG. 11).
Call. Also, if the cursor key CSR is operated while the “Voice Mode Selection” page is displayed,
"Voice mode selection cursor key on event subroutine" EP in entry point table EPT (Fig. 11)
Call CD (nE).

The voice mode selection numerical input subroutine EPDS (nE) and the voice mode selection cursor key on event subroutine EPCD (nE) will be described with reference to FIG. 18. First, when the data input section 42 is operated, the data input section Voice mode VM according to the number entered by 42
Change the ODE (step 78).

Next, the position of the cursor on the display unit DPY is moved to the position of the specific voice mode specified by the new voice mode VMODE (step 79).

The tone generator types of the respective elements 1 to 4 in the voice mode are read from the element type table ETT (FIG. 9) in accordance with the new voice mode VMODE, and an element configuration display corresponding to this is performed on the upper right of the screen of the display unit DPY ( Step 80).

Next, the values of the edit start pointers EDS (1) to EDS (4) of the elements 1 to 4 in the edit buffer memory VEB are reset according to the new voice mode VMODE (step 81). This is for adjusting each of the edit start pointers EDS (1) to EDS (4) to the new voice mode VMODE.

Next, referring to the element type table ETT according to the contents of the new voice mode VMODE, the number of simultaneous sounds that can be performed in that voice mode (element type table ET)
The value in the column of the number of simultaneously soundable characters of T is determined, and this is stored in the simultaneously soundable number register NSCH (step 82).

When the cursor key CSR is pressed, the voice mode VMO
The value of DE is increased by 1 (step 83). In order to change the value of the voice mode in the range of 1 to 10, when the value of VMODE increased by 1 becomes larger than 10, the value of VMODE is reset to "1" (steps 84 and 85). ). afterwards,
The processing of steps 79 to 82 described above is performed.

As is clear from the above, according to the operation of the data input unit 42, a desired voice mode can be selected at a time,
With the cursor key CSR, the voice mode VMODE
Finally, a desired voice mode is selected by shifting the value of.

Editing of Common Data If it is determined in step 68 of FIG. 16 that the value of the edit mode EMODE is 1, a common data edit introduction subroutine COMSUB is performed. This subroutine COMSUB
An example is shown in FIG.

First, in step 86, the content of the current page PAGE indicating the page of the display unit DPY is set to a predetermined value nE + 1 indicating the “common data edit” page.

In the next step 87, the screen display of the display unit DPY is changed to a page of a “common data edit” menu as exemplified in FIG. 29, various common data names are displayed, and a cursor is moved to the currently selected common data name. At the same time, the sound source type of each of the elements 1 to 4 in the currently selected voice mode VMODE is displayed on the upper right. The display corresponding to each of the function switches F1 to F5 is performed in the same manner as described above. Here, the function switch display corresponding to the element not used in the element configuration in the currently selected voice mode VMODE is not performed. In the example of FIG. 29, “E3” and “E4” are not displayed.

The process of changing the screen display of the display unit DPY to the page of the “common data edit” menu as illustrated in FIG. 29 is performed without using the common data edit introduction subroutine COMSUB as described above. It may be. In other words, on the edit mode pages other than the “Common Data Edit” menu page, as described above, the function of selecting the common data editing is assigned to the function switch F2, and these are displayed on the display unit DPY. When the function switch F2 is turned on while the edit mode page is displayed, the "common data edit subroutine" EPCOM is called in the entry point table EPT (FIG. 11).

This common data edit subroutine EPCOM is the first
In Fig. 9, common data edit introduction subroutine C
Shown with OMSUB. Here, in step 88, the edit mode EMODE is set to "1" indicating "common data edit".
Perform 6,87 processes.

When the page of the “Common Data Edit” menu as shown in FIG. 29 is displayed on the display unit DPY in this way, when the data input unit 42 or the cursor key CSR is operated next, the cursor is correspondingly changed. Moves,
Desired common data can be selected. After selecting the desired common data, enter key ENTER (7th
Press (Fig.) To enter the Entrance Point Table EPT (11th
Subroutine EPET (nE + 1) below “Common Data Edit” is called with reference to FIG.
The page of the display unit DPY is switched to the lower page, and the details of the desired common data can be changed and rectified. The description of the lower subroutine EPET (nE + 1) will be omitted.

Data editing for each element Here, the data editing for the element 1 will be described in detail, and the data editing for the other elements 2 to 4 is substantially the same processing, so detailed description will be omitted.

If it is determined in step 68 of FIG. 16 that the value of the edit mode EMODE is 2, an edit introduction subroutine E1SUB for element 1 is performed. This subroutine E1SUB
An example is shown in FIG.

First, in step 89, the element type table ETT is referred to according to the voice mode VMODE, and the element 1
And stores it in the element type buffer ETBUF.

Next, in step 90, the element type buffer ET
Check the value of BUF. If "0", that is, if this element is not used, this subroutine is ended. If "1", that is, if it is FM type, the flow goes to step 91 to change the contents of the current page PAGE indicating the page of the display unit DPY to It is set to a predetermined value nE + 2 indicating the "FM data edit" page.

In the next step 92, the screen display of the display unit DPY is changed to a page of the “FM data edit” menu as illustrated in FIG. 30, and various FM parameter data names are displayed, and the currently selected FM parameter data name is displayed. And the sound source type of each of the elements 1 to 4 in the currently selected voice mode VMODE is displayed on the upper right.
The display corresponding to each of the function switches F1 to F5 is performed in the same manner as described above.

To explain an example of the FM parameters, Algo is an algorithm parameter for setting a connection combination of the FM operation units OP1 to OP6. OpEG is a parameter for setting an envelope waveform for each of the operation units OP1 to OP6. Also,
FBPCL is the feedback level data FL1 to FL6 and the external input level control data EX for each of the operation units OP1 to OP6.
These are parameters for setting TL1 to EXTL6 (see FIG. 4).

On the other hand, the value of the element type buffer ETBUF is "2"
That is, if it is a PCM type, go to step 93 and display section D
The contents of the current page PAGE indicating the page of PY are displayed in “PCM
It is set to a predetermined value nE + 3 indicating a "data edit" page.

In the next step 94, the screen display of the display unit DPY is changed to a page of a “PCM data edit” menu as illustrated in FIG. 31, and various PCM parameter data names are displayed.
Place the cursor on the currently selected PCM parameter data name and select the currently selected voice mode VMODE.
The sound source types of the respective elements 1 to 4 are displayed on the upper right. Also, as described above, each function switch F1
The display corresponding to F5 is performed.

In step 95, the edit mode EMODE is set to "2" instructing the data editing of the element 1. The setting of "2" in step 95 is the edit mode
It is valid when the value of EMODE is still other than "2".

The process of changing the screen display of the display unit DPY to the page of the “FM data edit” menu or the “PCM data edit” menu as illustrated in FIG. 30 or FIG. E1SU
Edit subroutine E for element 1 irrespective of B
It may be by PE1. That is, in the various edit mode pages, as described above, the function of selecting the data editing of the element 1 is assigned to the function switch F3, and these edit mode pages are displayed on the display unit DPY. When the function switch F3 is turned on while the switch is ON, the "edit subroutine for element 1" EPE1 is called in the entry point table EPT (FIG. 11).

This element 1 edit subroutine EPE1
In FIG. 20, it is shown together with the introduction subroutine E1SUB of the element 1. Here, in step 96,
Check if the edit mode EMODE is already set to "2", which indicates "edit element 1".
If S, the routine returns without further executing this subroutine. However, if NO, it means that the mode has been switched from another edit mode to the edit mode of the element 1. Therefore, the subroutine is continued, and the above-described steps are performed.
The processing of 89 to 95 is performed.

In the state where the page of the “FM data edit” menu or the “PCM data edit” menu as illustrated in FIG. 30 or FIG. 31 is displayed on the display unit DPY, the data input unit 42 or the cursor is next displayed. When the key CSR is operated, the cursor moves in accordance with the operation, and desired parameter data can be selected. After selecting the desired parameter data, press the ENTER key
Press (Fig. 7) to enter the entry point table EPT
Referring to (Fig. 11), the subroutine EPET (nE + 2) or EPET (nE + 3) of the lower menu of the "FM data edit" menu or the "PCM data edit" menu is called, and the page of the display unit DPY is set to the lower page according to this. To change or correct the details of the desired FM or PCM parameter data. The description of the lower subroutine EPET (nE + 2) or EPET (nE + 3) will be omitted.

An example of changing / modifying the detailed contents of the FM parameter data will be described. In the page of the “FM data edit” menu in FIG. 30, when the edit of the parameter FBPCL of the number 9 is selected (that is, the cursor is moved to the number 9 and the enter operation is performed). When the key ENTER is pressed), the display section DPY switches to a page for feedback and PCM level editing as shown in FIG. On this page screen, the cursor key CSR and the data input unit 42 are appropriately operated to provide the feedback level and PCM for each of the arithmetic units OP1 to OP6 of the FM sound source 18.
Set each level to the desired value. As described above, the feedback level is level data for setting a ratio of returning its own arithmetic unit output as its own modulated wave signal, and corresponds to the feedback level data FL1 to FL6 in FIG. The PCM level means that the output tone signal of the PCM sound source 17 is converted into each of the arithmetic units OP1 to OP of the FM sound source 18.
Level data for setting the ratio of input as a modulated wave signal to P6, which corresponds to the external input level control data EXTL1 to EXTL6 in FIG. As described above, when no feedback or PCM modulated wave signal is used, the level data values are set to 0.

The above is the description of the data editing for the element 1, but the data editing for the other elements 2 to 4 can be performed in substantially the same procedure.

That is, in step 68 of FIG. 16, the edit mode EM
If it is determined that the value of ODE is 3, an edit introduction subroutine E2SUB for element 2 is performed (step 7).
2) If EMODE = 4, an edit introduction subroutine E3SUB for element 3 is performed (step 73), and EMODE = 5
In case of, edit introduction subroutine E4 of element 4
SUB is performed (step 74). When the edit mode page is displayed on the display unit DPY, by turning on the function switches F4 to F6, the element 2 in the entry point table EPT (FIG. 11) is displayed.
4 to "Edit subroutine" are called and executed.

Store processing Store key STORE when desired edit is completed
Press (FIG. 7) to set the mode in which the edited voice data is returned from the voice edit buffer memory VEB to the voice data memory VDM.

When the store key STORE is pressed when the display screen of the display unit DPY is a page in any edit mode, a “store subroutine” EPST is called in the entry point table EPT (FIG. 11). This store subroutine EPST
A detailed example is shown in FIG.

In the store subroutine EPST, first, the page buffer
The page data of the current page PAGE is transferred to PAGEBUF, and the content of the current page PAGE is set to a predetermined value nS indicating the “store” page. The page buffer PAGEBUF is provided to return the screen to the original page during the storage processing or after the storage processing is completed. Next, the screen display of the display unit DPY is changed to a “store” page as illustrated in FIG. 33, the current voice number and the voice name are displayed, and the voice name corresponding to each voice number is displayed. Place the cursor at the position of the voice number indicated by the voice number STVN. The QUIT key QUIT is displayed according to the function switch F1, and the start key is displayed according to the function switch F8.
Display STRT.

In the state where the “store” page as illustrated in FIG. 33 is displayed on the display unit DPY in this way, when the data input unit 42 or the cursor key CSR is operated next, the store voice number STVN is changed accordingly. The value is changed, and a desired voice number for which edited voice data is to be stored can be selected.

To explain this point, when the data input unit 42 is operated while the “store” page is displayed, the “store voice number numerical input subroutine” EPDS (nS) is called in the entry point table EPT (FIG. 11). . Also, with the “Store” page displayed,
When the cursor key CSR is operated, the "cursor key on event subroutine" EPCD (nS) for selecting the store voice number is displayed in the entry point table EPT (FIG. 11).
Call.

Store voice number input subroutine EPDS (nS)
The cursor key on event subroutine EPCD (nS) will be described with reference to FIG. 22. First, the data input section
When the button 42 is operated, the value of the store voice number STVN is changed according to the numerical value input by the data input section 42. Next, the position of the cursor on the display unit DPY is moved to the position of the specific voice number indicated by the new store voice number STVN. When the cursor key CSR is pressed, the value of the store voice number STVN is incremented by 1 by modulo 16, and then the position of the cursor on the display unit DPY is changed to the specific voice number indicated by the new store voice number STVN. Move to position.

After registering the desired voice number for storing the edited voice data in the store voice number STVN, the start key STRT (that is, the function switch F8) is turned on. Then, the “store execution subroutine” in FIG. 23 is called by the entry point table EPT. Here, first, a display such as “Now Storing” indicating that the store is being executed is displayed at the bottom of the screen of the “store” page. Then, according to the store voice number STVN, the store voice pointer STVP
Set. This store voice pointer STVP points to the head address of the voice data area in the voice data memory VDM corresponding to the voice number of STVN.

Then, the data in the voice edit buffer memory VEB is transferred to the voice data area in the voice memory VDM indicated by the store voice pointer STVP.
In that case, not all the data in the whist edit buffer memory VEB is transferred, but necessary data is transferred according to the contents of the voice mode VMODE. First, the “voice name”, “voice mode”, and “common data” of the common data buffer CDB are transferred to a corresponding area of the voice data area in the voice memory VDM. Next, FM
The four FM element edit buffers 1 to 4 and the PCM edit buffer PCM in the edit buffer FMEB
4 PCM element edit buffers in EB 1
Only the data necessary for the contents of the voice mode VMODE are transferred to the corresponding element parameter data area of the voice data area in the voice memory VDM.

Thereafter, the content of the current page PAGE is changed to the next page nS + 1, and a predetermined store end display (for example, “Complete!” Is displayed at the bottom of the screen) is performed.

In the “store” page of page number nS or the “store end” page of nS + 1, the function switch F1 functions as a quit key QUIT, and when it is turned on, the quit key on event subroutine of FIG. 24 is executed. Here, the page data of the page buffer PAGEBUF is moved to the current page PAGE, and the current page PA
Call a routine to enter the page indicated by GE. As a result, when the quit key QUIT is turned on during the storing process or after the storing process is completed, the display DP
The screen of Y is returned to the page screen of the processing immediately before entering the store processing. This enables redoing of editing and the like.

When the key is newly pressed, the key-on event processing shown in FIG. 25 is performed, and the sound of the pressed key is assigned to any one or a plurality of channels.

First, the key code of the pressed key related to the key-on event is stored in the key code register KCODE, and the corresponding touch data is stored in the touch data register TDATA (step 100).

Next, the primary allocation channel ASCH is determined according to the simultaneous soundable number registered in the simultaneous soundable number register NSCH,
A new pressed key is provisionally assigned to the primary assignment channel ASCH (step 101).

The primary assignment channel ASCH is used not at the actual sounding channel but at the stage prior to the assignment to the actual sounding channel. The number of channels ASCH in the first order corresponds to the number that can be simultaneously sounded. In the case of multi-sequence sounding of the same key, the same key is sounded and assigned to a plurality of channels in an actual sounding channel, but the same key is assigned to only one channel to the primary assigned channel ASCH. An example of the relationship between the number of simultaneously soundable NSCHs, the actual sounding channels having a total of 16 channels, and the primary assignment channel ASCH is as follows. Each of the 16 actual sound channels is represented by a number from 0 to 15, and each of the primary assignment channels ASCH is represented by a number from 0 to
Represented by number 15.

When the number of simultaneous sounds NSCH = 1: The primary assignment channel ASCH is only "0".

An actual sounding channel uses “0” to “3” according to the number of streams (the number of elements used). However, the same key is assigned to each sounding channel.

When the number of simultaneously audible sounds NSCH = 4: The primary assignment channel ASCH is a total of four “0” to “3”.

The actual sounding channels are a total of 4 groups including a group of “0” to “3”, a group of “4” to “7”, a group of “8” to “11”, and a group of “12” to “15”. Use Each group is assigned a different key. The same key is assigned to the channels in the same group according to the number of streams (the number of elements used).
For example, if only one element is used, a pressing key is assigned to only one channel in the same group, and if two elements are used, the same pressing key is assigned to two channels in the same group.

When the number of simultaneously audible sounds NSCH = 8: The primary assignment channel ASCH is a total of eight from "0" to "7".

The actual sounding channels are “0” and “1” groups, “2” and “3” groups, “4” and “5” groups, “6” and “7” groups, “8” and "9" group, "10" and "11" group, "1"
A total of eight groups, ie, the groups 2 and 13 and the groups 14 and 15 are used. Each group is assigned a different key. The same key is assigned to the channels in the same group according to the number of streams (the number of elements used).

When the number of simultaneous sounds NSCH = 16: The primary assignment channel ASCH is a combination of "0" to "15"
16 pieces.

The actual sounding channels use "0" to "15" individually. A different key is assigned to each sounding channel. The number of streams (the number of elements used) is one.

In step 101, the primary assignment channel ASCH determined as described above in accordance with the number of simultaneously soundable NSCHs
Is temporarily assigned to any one of. In the following, the symbol ASCH will be described as data specifying the number of one primary assignment channel that has been provisionally assigned in step 101.

In the next step 102, it is checked whether or not the provisional assignment is determined in the previous step 101. For example, if more keys than the number of simultaneously soundable keys are pressed at the same time, the provisional assignment may not be determined in step 101, and in that case, step 10
2 is NO. Step 1 if a tentative allocation decision is made
02 is YES and go to step 103.

In step 103, the element number i is set to "1".

In step 104, the tone generator type of the i-th element relating to the currently selected voice is extracted from the element type table ETT and registered in the element type buffer ETBUF.

The next step 105 is to determine the actual channel to which the tone signal generation for the ith element is assigned,
Channel buffer number CHBUF
Register with. This assignment channel is determined by the actual assignment routine shown in FIG. 26 based on the voice mode VMODE of the currently selected voice and the primary assignment channel ASCH provisionally assigned in step 101. The details will be described later.

In the next step 106, the element type buffer ETB
It is checked whether the type of the i-th element stored in the UF is 0, 1, or 2. "1" indicating that it is an FM sound source
If so, go to step 107, and for the channel indicated by the channel buffer CHBUF in the FM sound source 108, the parameter data and common data of the i-th element, the key code and touch data in KCODE and TDATA, and key-on. The key-on signal KON shown in FIG.

"2" indicating that the element type is a PCM sound source
If so, go to step 108, and for the channel indicated by the channel buffer CHBUF in the PCM sound source 17, set the parameter data and common data of the i-th element, the key code and touch data in KCODE and TDATA, and key-on. The key-on signal KON shown in FIG.

After step 107 or 108, go to step 109. On the other hand, "0" indicating that the type of the i-th element is not used
If so, the process proceeds to step 109 without performing data transmission to the tone generator channel as in step 107 or 108.

In step 109, it is checked whether i is 4 or more. If NO, the process goes to step 110, i is incremented by 1, and then step 104
And the routine of steps 104 to 109 is repeated. That is, a process of determining a tone assignment channel of a tone signal for another element is performed. When i becomes 4 or more, the key-on event process ends.

26. First, in step 111, it is checked whether the voice mode VMODE is 1 to 10.

In the case of the voice modes 1, 2, and 3 in which the simultaneous possible number NSCH is 1, the flow goes to step 112, where the channel corresponding to the value of i-1 is determined as the actually allocated channel and registered in the channel buffer CHBUF. Therefore, when i = 1, it is assigned to the channel of i-1 = 0, and when i = 2, it is assigned to i-
The same key is sequentially assigned to channels “0” to “3”, for example, assigning to 1 = 1 channel. In addition,
Step 107 or 108 for unused elements
Is not performed, so that it is substantially the same as the case where no assignment is made.

In the case of the voice mode 5 or 7 in which the number of simultaneous sounds NSCH is 8 and only one kind of sound source is used, go to step 113 and assign the channel corresponding to the calculation result of 2 × ASCH + i−1 to the actually allocated channel. And register it in the channel buffer CHBUF. Therefore, a key is called ASC
When H = 0 is temporarily assigned, when i = 1, it is assigned to the channel corresponding to the operation result “0”, when i = 2, it is assigned to the channel corresponding to the operation result “1”, and so on. The same key is assigned to channels “0” and “1”. If another key is provisionally assigned to ASCH = 1,
When i = 1, the same key is allocated to the channels corresponding to the operation result “2”, when i = 2, the channel is allocated to the channel “3”, and so on. .

In the case of the voice mode 8 in which the number of simultaneous sounds NSCH is 4, the process proceeds to step 114, where the channel corresponding to the calculation result of 4 × ASCH + i−1 is determined as the actually allocated channel and registered in the channel buffer CHBUF. Therefore, when a certain key is provisionally assigned to ASCH = 0, when i = 1, it is assigned to the channel corresponding to the operation result “0”, when i = 2, it is assigned to the channel “1”, i = 3 Is assigned to the channel of "2" when i is 4, "3" when i = 4
The same key is sequentially allocated to channels “0” to “3”, for example. When another key is provisionally assigned to ASCH = 1, if i = 1, it is assigned to the channel corresponding to the operation result "4", if i = 2, it is assigned to the channel "5", and so on. ,
The same key is sequentially assigned to channels “4” to “7”.

In the case of the voice mode 4, 6, or 9 in which the number of simultaneous sounds NSCH is 16, the process proceeds to step 115, and the value of the primary assignment channel ASCH is used as it is as the actual assignment channel and registered in the channel buffer CHBUF. Therefore, for example, when a key is provisionally assigned to ASCH = 0, regardless of the value of i,
The key is assigned to “0” of the actually assigned channel. Therefore, in the case of the voice mode 9 in which two types of sound sources are used, for example, when a certain key is provisionally assigned to ASCH = 0, the tone signal of the element 1 corresponding to the FM sound source is set to the channel “0” of the FM sound source. The assigned tone signal of the element 2 corresponding to the PCM tone generator is assigned to the same channel “0” of the PCM tone generator. Thus, the same key is assigned to the same channel of different sound sources.

In the case of the voice mode 10 in which the number of simultaneously soundable sounds NSCH is 8 and two kinds of sound sources are used, the process goes to step 116 and the channel corresponding to the calculation result of 2 × ASCH + mod [(i−1) / 2] Is determined as an actually allocated channel and registered in the channel buffer CHBUF. Therefore, a key is A
When tentatively assigned to SCH = 0, if i = 1, mod [(i
−1) / 2] = 0, so that it is assigned to the channel corresponding to the operation result “0”. When i = 2, mod [(i−1) /
2] = 1, it is assigned to the channel corresponding to the operation result “1”. When i = 3, mod [(i−1) / 2] =
Since it is 0, it is assigned to the channel corresponding to the operation result "0". When i = 4, since mod [(i-1) / 2] = 1, it is assigned to the channel corresponding to the operation result "1". Thus, the tone signals of the elements 1 and 2 corresponding to the FM sound source are assigned to the channels “0” and “1” of the FM sound source, and the tone signals of the elements 3 and 4 corresponding to the PCM sound source are assigned to the PCM sound source.
The sound sources are assigned to the same channels “0” and “1”, respectively. If another key is provisionally assigned to ASCH = 1,
The tone signals of the elements 1 and 2 corresponding to the FM sound source are assigned to the channels “2” and “3” of the FM sound source, and the tone signals of the elements 3 and 4 corresponding to the PCM sound source are assigned to the same channels “2” and “ 3 "respectively.

Modifications The type of sound source is not limited to PCM and FM, and other types may be used. For example, as a modulation operation type sound source, not only FM but also a sound source based on amplitude modulation operation (AM) or window function operation is known, and these may be used as appropriate. Also, a sound source based on a harmonic synthesis method, a subtraction type sound source using a filter, or the like may be used. Further, the sound source systems of the first and second sound source means should be different. However, even if the basic principle is the same, any configuration can be used as long as it can create a unique sound. Also, one of the first and second sound source means
Combinations such as FM sound sources and AM sound sources on the other are also possible.

In the above embodiment, the number of streams (that is, the number of elements) in each sound source is automatically determined by the voice mode of the selected voice. For example, referring to FIG. 9, in voice mode 5, the number of FM sound source sequences = 2,
The number of sequences of the PCM sound source = 0. In the voice mode 7, the number of FM sound source sequences = 0 and the number of PCM sound source sequences = 2.
In the voice mode 10, the number of FM sound source sequences = 2 and the number of PCM sound source sequences = 2. However, instead of automatically determining the number of streams of each sound source depending on the mode, it may be possible to set arbitrarily individually by the player. In one embodiment, a table similar to the element type table ETT in FIG. 9 may be arbitrarily created.

The channels in each sound source are not limited to the time division type, but may be of the parallel type.

The number of voices that can be generated at the same time is not limited to one, and may be plural. In this case, channel assignment may be performed using a DVA (Dynamic Voice Allocation) technique.

In voice mode using only one sound source,
The other unused sound source may be used for an appropriate purpose. For example, an unused sound source may generate a musical tone corresponding to performance information provided from a sequencer or an external device. Further, when the channel of the sound source to be used is all busy, the overflowing sound may be conveniently generated by the sound source that is not originally used.

In order to simultaneously control the tone generation of the output tone signals of the two sound sources, the mixing circuit 23 is provided in the above embodiment, and the output tone signals of the two sound sources are added (or subtracted) and synthesized on the electric circuit. However, the present invention is not limited to this, and it is also possible to control the tone generation level of the output tone signals of both sound sources and then sound them from separate speakers and spatially add and synthesize them.

〔The invention's effect〕

As described above, according to the present invention, one composite tone is composed of a plurality of element tones, and for each element tone, which tone generator means should generate a corresponding partial tone signal is individually indicated by element type information. As a result, it is possible to form a single complex tone by utilizing sound source means composed of different sound source systems in various combinations, thereby expanding the sound making, and making more complex and diverse sound making. It has an excellent effect that it becomes possible.

Also, since each sound source means has a plurality of tone generation channels, and each channel independently generates a tone signal, a plurality of different element tones can be generated by using the plurality of channels of one sound source means. Corresponding partial tone signals can be respectively generated, and sound can be created in various forms. That is, some of the plurality of element tones are generated using a certain sound source means,
Since some of the others can be generated using different sound source means, it is possible to form musical tone timbres in optimal and various combinations corresponding to each selectable timbre,
An excellent effect that a tone having a high-quality composite tone can be generated by using a combination of tone generators of an optimal tone generator method for each element tone. Especially,
By generating optimal element type information and parameter information corresponding to one selected timbre, by appropriately using each channel of each sound source means in an optimal combination corresponding to the selected timbre, Based on these combinations, it is possible to generate a musical tone having a composite tone optimal for the selected tone.

Further, for one of the element tones in the one composite tone, it is possible to instruct to change or set the contents of the parameter information, and in accordance with the element type information relating to the instructed element tone, the sound source means It is automatically controlled so that the contents of parameter information suitable for the sound source method are changed or set, so it is necessary to specify which element sound depends on which sound source method when editing the tone data. And an excellent effect that operability of editing work is improved.

Further, the tone data of the desired composite tone to be edited in the tone data is stored from the data memory to the editing storage means, and the tone data stored therein is subjected to data editing such as change and setting. So,
If the storage capacity of the edit storage unit is secured extra, it can be provided when the data amount is expanded by editing, or when the sound source system of the element is changed, etc.
This has an excellent effect that the degree of freedom of editing work is improved.
