In this case, when setting the tone included in the plug-in board installed in the slot 1 to the part, the user operates the button “slot 1” and then sets any of the buttons “1” to “9” or the button “D”. Operate. When setting the tone of the plug-in board installed in the slot 2 to a part, the user operates the button "slot 2" and then operates any of the buttons "1" to "9" or the button "D". Operate. However, one of the button “slot 1” and the button “slot 2” is in a selected state, and if the selected slot is sufficient, it is not necessary to operate the button again. The buttons “1” to “9” are selection buttons for selecting a board preset voice or a board custom voice included in the plug-in board. The voice selected by the buttons “1” to “9” is an electronic musical instrument. Offset editing, which will be described later, is enabled in the main body 1. Buttons “1” to “9” can be assigned voices of up to 20 tones per button, and any one of them can be selected. The button “D” is a selection button for selecting a board preset voice or a board custom voice included in the plug-in board. The voice selected by the button “D” cannot be edited in the electronic musical instrument main body 1. An arbitrary number of voices provided in the plug-in board can be assigned to the button “D”, and any one of the voices can be selected.

In the example shown in FIG. 1, since the plug-in board 2 is mounted in the slot 1, here, the button "slot 1" is operated to select the slot 1, and then, for example, the button "1" is operated. And At this time, the tone color name of the tone assigned to the button "1" is displayed on the dot matrix display DP, and an example of the display screen is shown in FIG. In the display screen shown in FIG. 6, "Slot1-
"Flash1" is displayed, indicating that the board custom voice provided in the plug-in board 2 installed in the slot 1 is selected. Next, in a state where this display screen is displayed, for example, when the B button of the LCD button 1 is operated, the tone of the tone name “Live! Orch” of the board custom voice is set to the selected part. Become. Alternatively, for example, when the G button of the LCD button 2 is operated, the tone color of the tone color name “Orch. Brass” of the board custom voice is set to that part. Note that the number of tones that can be assigned to the buttons “1” to “9” in the board tone selection button B4 is a maximum of 20 tones, and the LCD corresponding to page P1 and page P2 displayed at the bottom of the display screen By operating the button 3, the tone names of the selected page are displayed at a maximum of ten tones. The display screen shown in FIG. 6 displays ten tone colors on page P1.

The tone names of board preset voices and board custom voices provided on a plug-in board which is a sound source board displayed on the dot matrix display DP at the time of tone color selection operation are stored in the flash ROM 11. This is a timbre name in the timbre map described above. The information of the tone bank number + program change assigned to the buttons “1” to “9” of the board tone selection button B4 is stored in the flash ROM 11 for each of the slots 1 and 2. The tone color assignment information is stored in a storage area. When one of the board preset voice and the board custom voice displayed on the dot matrix display DP is selected for the selected part by performing the above tone color selection operation, the tone is stored in the flash ROM 11. The information of the bank number + program change corresponding to the selected tone color name is sent to the plug-in board mounted on the previously designated slot 1 or slot 2. here,
If the slot 1 is selected, a bank number and a program change corresponding to the selected tone name are transmitted to the plug-in board 2.

In the plug-in board 2, the tone data of the tone corresponding to the bank number and the program change is read out from the ROM or RAM built in the plug-in board 2 and written into the sound generation area of the RAM. Become. If the selected timbre is a plug-in custom voice edited by adding correction data to timbre data, the bank number + program change is stored in the storage area of the flash ROM 11 assigned to each button. Correction data is also stored, and this correction data is also sent to the plug-in board 2. Then, the corresponding tone color parameters in the tone color data corresponding to the bank number and the program change are corrected by the correction data, and are written in the sound generation area of the RAM. This allows
When a performance event of the part occurs, a tone of the tone specified in the part is generated on the plug-in board 2. The tone selection operation for setting the tone provided on the plug-in board of the sound source to the selected part is performed by a simple operation and procedure of part selection → slot SW operation → button 1 to 9 or D operation → LCD button operation. Therefore, the tone color selection operation of the selected part can be easily performed even during the performance.

Incidentally, the plug-in board 2 shown in FIG.
In the case of a mono-part sound source, the tone color can be set for only one part. That is, when the tone provided in the plug-in board 2 is already used for another part, the tone of the plug-in board 2 cannot be set in another part. Therefore, in the tone generating apparatus of the present invention, even if the selected tone is the tone of the monopart sound source and has already been set to another part, the other part in which the selected tone is currently set is set. , The use of the timbre is prohibited, and the timbre of the monopart sound source is set for the part for which the timbre is newly selected. In this case, if there is a tone that replaces the tone of the mono part sound source set in the other part,
The alternative tone is assigned to another part, and if there is no alternative tone, the sound of the other part is muted. In the configuration shown in FIG. 1, the substitute tone is the tone provided in the tone generator 27 of the electronic musical instrument main body 1, and the tone generator 27 generates tone of another part instead of the plug-in board 2 of the monopart sound source. Become. However, if the other part for which the selected tone is currently set is a hand-operated part using the keyboard 5, the tone of the hand-operated part is not changed and the part for which the newly selected tone is selected is used. A substitute tone for the selected tone is set. If there is no alternative tone, the tone of the part for which the tone is newly selected is muted. This is because it is not preferable to change the timbre of the hand performance during the performance. Note that the use of the tone of the selected mono part sound source is prohibited in the other parts that are currently set, and when setting the tone newly to the selected part, whether such a setting may be made is acceptable. A message “OK?” May be displayed to ask the user to confirm the user.

Also, there is a plug-in board having a voice including a sequence depending on the plug-in board of the sound source. A sequence-incorporated voice is a pattern that indicates the relative pitch, sounding timing, and duration of multiple notes, such as arpeggio patterns, in addition to normal data such as waveform shape, pitch changes, and volume envelope changes in tone data. A tone that contains data. When a voice including the sequence is selected, a plurality of note-on / note-offs corresponding to the pattern data are generated in response to a sounding instruction (note-on). In this case, the voice including the sequence is the tone of the plug-in board, and the performance data of the part that selected the tone is MIDI.
When supplied directly from the IN terminal 17 to the plug-in board, a musical tone is played at a unique timing of the plug-in board. In other words, the timing is not synchronized with the timing of the tone generated by the tone generator 27 of the electronic musical instrument main body 1. Therefore, in the tone generating apparatus of the present invention, the MID input from the terminal 17 of MIDI IN
The I signal and the MIDI signal generated by the electronic musical instrument main body 1 are merged and supplied to the plug-in board. Thus, the performance by the plug-in board and the performance by the electronic musical instrument main body 1 can be synchronized. Further, when performing the automatic performance / automatic accompaniment in the electronic musical instrument main body 1, the tempo clock of the automatic performance / automatic accompaniment is supplied to the plug-in board.
This makes it possible to synchronize the pattern of the voice including the sequence performed by the plug-in board with the automatic performance / automatic accompaniment performed by the electronic musical instrument body 1.

Next, a tone color editing operation performed by the user when offset-editing a board preset voice or a board custom voice provided in the plug-in board shown in FIG. 11C will be described. For the explanation, the editing of the timbre in the electronic musical instrument main body 1 according to the present invention will be described. In the electronic musical instrument main body 1 according to the present invention, the correction data is added to the tone parameter without changing the value of the tone parameter stored in the tone data storage area of the ROM or RAM of the plug-in board mounted. It allows editing by. That is, when a timbre parameter to be changed is selected from a plurality of timbre parameters constituting one timbre data and the parameter value is corrected, the data of the corrected timbre parameter without changing the timbre parameter value ( Hereinafter, “correction data” is held. Then, when the timbre is selected by operating any of the buttons “1” to “9” in the board timbre selection button B4, the edited timbre parameter is reflected by reflecting the correction data in the timbre parameter. To get. Such editing is hereinafter referred to as “offset editing”, and a tone edited by offset editing is called a plug-in custom voice. This offset editing is performed when the plug-in board
It can be performed even when it is not provided. The correction data is added to the bank number + program change information corresponding to the edited timbre in the storage area of the assigned timbre information of the buttons “1” to “9” prepared for each slot in the flash ROM 11 ( Bank number +
Program change + correction data) are stored.
That is, the plug-in custom voice can be selected only by the buttons “1” to “9” of the board tone color selection button B4. Therefore, the plug-in custom voice can be selected only by the player of the electronic musical instrument main body 1. In the method of inputting the bank select + program change information from the MIDI IN terminal 17 and referring to the tone color map, the plug-in custom voice can be selected. Can't choose. Editing of the tone parameter value itself is possible, for example, by a personal computer 9 connected to the electronic musical instrument main body 1. Tone data consisting of the tone parameters edited in the personal computer 9 is plugged in from the personal computer 9. It can be loaded into the RAM of the board. The tone edited by the personal computer 9 is called a board custom voice. This board custom voice is an electronic musical instrument body 1
Of the board tone color selection button B4 can be selected by operating the
The selection can be made by referring to the tone color map from the bank select + program change information input from the terminal 17 of IDI IN.

The correction data by the offset editing is held in the work area on the system RAM 12 in association with the tone name information of the edited tone at the time of the offset editing. The tone name of the tone that has been subjected to offset editing can be re-assigned to an arbitrary tone name, and the tone data is changed or not changed.
Add to the information of the bank number + program change corresponding to the edited tone in the storage area of the assigned tone color information of the button "9" (bank number + program change +
Correction data) and stored. That is, when the edited tone is a board custom voice, the board custom voice is replaced with a plug-in custom voice. As a result, the plug-in custom voice, which is the tone that has been subjected to the offset editing, can be selected by the buttons “1” to “9” of the board tone color selection button B4.

Returning to FIG. 11C, a tone color editing operation for offset-editing a board preset voice or a board custom voice provided in the plug-in board will be described. When performing the tone editing operation, the Edit button B1 shown in FIG. 3 is operated. As a result, the display screen of the custom voice creator shown in FIG. 7 is displayed on the dot matrix display DP. On this display screen, “CUSTOM VOICE CREATOR: Solo Violin
Is displayed, indicating that the tone with the tone name "Solo Violin" is selected and edited. On the display screen,
One of a "tone color selection" window, a "standard parameter" window, an "individual parameter" window, an "effect parameter" window, and a "save" window can be selected and displayed. By selecting and displaying the “tone color selection” window, the tone color name to be offset-edited can be selected. When this "tone color selection" window is selected, the displayed tone color names are the tone color names assigned to the buttons "1" to "9" for each of the slots 1 and 2 in the board tone color selection button B4. Since a maximum of 20 tones can be assigned to each of the buttons "1" to "9", a maximum of 180 tone names can be displayed for each of the slots 1 and 2, and any one of the tones can be selected.

In FIG. 7, a "standard parameter" window is displayed. The standard parameters are common parameters in the sound source regardless of the sound source type of the plug-in board. The standard parameters displayed in FIG.
Parameter 1 is the filter's cutoff frequency parameter FREQ and the filter's resonance parameter RESONANC
The parameter 2 is an attack parameter ATTACK of the envelope generator (EG), a decay parameter DECAY, and a release parameter RELEASE. The current settings of these parameters are shown below in a bar graph. This set value can be arbitrarily changed by operating either the up key or the down key of the LCD buttons 2 to 7 corresponding to the up / down mark displayed at the lower end. For example, the parameter FREQ can be offset-edited between -64 and +64.
If it is edited to "3", "+3" is the correction data in the offset editing. This modified data is
Tone name "Solo Violin" offset edited in RAM12
Is held in association with. Other parameters can be offset-edited in the same manner. The standard parameters include parameters other than the above two parameters, and these parameters are displayed by scrolling the screen upward by operating the button C of the LCD button 1. By operating the button B of the LCD button 1, the screen is scrolled down.

Next, the "individual parameter" window is operated by operating the LCD button 1 to display the dot matrix display DP.
FIG. 8 shows a display screen displayed on the screen. The individual parameters are parameters specific to the sound source corresponding to the sound source type of the plug-in board, and FIG. 8 shows individual parameters of an analog modeling sound source that models an analog synthesizer. In FIG. 8, the parameter “VCO2 PWM D
An underline is displayed below "epth" to indicate that this parameter is selected and editable. At this time, by operating the up key or the down key of the button 6 or the button 7 of the LCD button 3 corresponding to the up / down mark UD2, the value of the parameter "VCO2 PWM Depth" can be corrected and offset edited. . For example, change VALUE from "10" to "15"
, "+5" becomes the correction data in the offset editing. This modified data is stored in the system RAM
12 is held in association with the tone color name “Solo Violin” that has been offset-edited. Other parameters can be offset-edited in the same manner. To select another parameter, the L corresponding to the up / down mark UD1
The up key or the down key of the CD button 4 may be operated.

The parameter names of the parameters displayed on the dot matrix display GP when editing the timbre are the parameter names of the board preset voice and the board custom voice included in the plug-in board. 1 can be loaded from the plug-in board into the flash ROM 11 when the power is turned on. If the plug-in board is not replaced when the power is turned on, the table of the parameter name information of the board preset voice and the board custom voice of the plug-in board stored in the flash ROM 11 without being loaded is directly used. used. The parameter name information thus obtained is displayed on the dot matrix display DP at the time of tone color editing.
As for the displayed parameter value, when the parameter name is displayed, a parameter value corresponding to the displayed parameter name is obtained by inquiring the corresponding plug-in board, and the parameter value is displayed together with the parameter name. I have.

Further, it is assumed that the "effect parameter" window is displayed by operating the LCD button 1 (not shown). In this case, it is possible to select the part to which the effect is to be applied and edit the effect to be applied. In effect editing, effects such as reverb, chorus, variation, and distortion can be edited. Further, although not shown, it is assumed that the “storage parameter” window is displayed by operating the LCD button 1. In this case, it is possible to save the standard parameter and the edited data of the individual parameters that have been offset-edited on the display screen, that is, the corrected data of the plug-in custom voice. In this case, the tone color name of the tone color that has been subjected to offset editing can be updated or saved without being updated. The edited effect parameters can be stored in the flash ROM 11.

Next, a description will be given of a siphoning operation performed by the user when the tone color data of the board custom voice provided in the plug-in board shown in FIG. When the operation of downloading the tone color data of the board custom voice provided in the plug-in board to the flash ROM 11, the Get button B6 shown in FIG. 3 is operated. As a result, "OK?" Is displayed on the dot matrix display DP indicating whether or not to continue the execution of the siphoning operation.
When the o button B3 is operated, the tone data of the board custom voice is stored in the flash ROM 1 from the plug-in board 2.
You will be able to siphon up to 1. In this case, the board custom voice is stored in the RAM of the plug-in board 2, and after the area for storing the board custom voice in the flash ROM 11 is cleared, the board custom voice read from the RAM of the plug-in board 2 is stored in this area. Voice color data of the voice is written. This siphoning operation is preferably performed when a board custom voice is loaded from the personal computer or the like into the RAM of the plug-in board 2, whereby the latest board custom voice can be saved. By updating the timbre map with timbre name information, the latest board custom voice can be used.

Next, the flash RO shown in FIG.
The save operation performed by the user when saving the tone color data of the board custom voice of the plug-in board and the correction data of the plug-in custom voice stored in the M11 to the disk 8 of the disk drive 7 will be described. To save the tone data of the board custom voice of the plug-in board and the correction data of the plug-in custom voice stored in the flash ROM 11 to the disk 8, the save button B7 shown in FIG. As a result, a display screen for selecting either “quick save” or “complete save” is displayed on the dot matrix display DP. When "quick save" is selected here, correction data and style data in the plug-in custom voice except for the tone data of the board custom voice stored in the flash ROM 11 are saved on the disk 8 of the disk drive 7. When "complete save" is selected, the tone data of the latest board custom voice stored in the RAM of the plug-in board is once transferred to the flash ROM 11, and then the correction data and style data of the plug-in custom voice are transferred. In addition, the data is saved on the disk 8 of the disk drive 7. "Complete save"
In, to rewrite the tone data of the board custom voice that exists on the RAM of the plug-in board,
This is because the tone color data of the board custom voice stored in the flash ROM 11 is not always the same. When the user wants to cancel the operation described above, the user operates the Exit button B2. Thereby, the operation can be canceled.

Next, the system C in the electronic musical instrument main body 1
The CPU main processing executed by the PU 10 will be described with reference to the flowchart shown in FIG. Electronic musical instrument body 1
Is turned on, the CPU main process is started. Then, in step S1, it is detected whether the plug-in boards are mounted in the slots 1 and 2, and if so, what type of plug-in boards are mounted and their specific information are detected. Is done. In this case, the device number DN is set to “1” and the information of the plug-in board attached to the slot 1 is detected, and then the device number DN is set to “2” and the plug-in board attached to the slot 2 is detected. Board information is detected. Here, the type and specific information of the detected plug-in board are stored in the system RAM 12. When the plug-in board is a sound source board, information on a monopart sound source / multipart sound source, a selectable tone number ( Bank select MSB + bank number + program change) is detected. When the plug-in board is an effect board, a selectable effect number is detected. Note that the detection of the plug-in board and the initial setting processing based on the detection result are performed not when the power is turned on but when the board is mounted or periodically, so that the environment of the electronic musical instrument main body 1 is kept up to date. It may be.

Next, an initial setting process is performed in step S2. This initialization process will be described later, but the slot 1
It is determined whether or not the plug-in board installed in the slot 2 has been replaced. If the plug-in board has been replaced, timbre name information and timbre parameter name information are obtained from the plug-in board, and the timbre is determined based on this. The map and the tone parameter name table are updated. When the initial setting process ends, a factor check is performed in step S3, and it is determined in step S4 whether a factor for performing the process has occurred. Here, the “factor” is, for example, MIDI
This means that a MIDI signal has been input from the IN terminal 17 or the keyboard 5, an event of operating one of the panel switch buttons on the panel display & SW 6, an event of another type, or the like. In steps S3 and S4, the process waits until it is determined that a factor has occurred.

Here, when a MIDI signal is input from the MIDI IN terminal 17 or the keyboard 5 and it is determined in step S4 that there is a factor, the factor is determined to be MIDI input in step S5, and the flow branches to step S6.
In step S6, an event process corresponding to the MIDI signal input by MIDI is performed. For example, MID
If the I signal is note-on, the tone generator 27 or the plug-in board 2 that generates the tone of the part indicated by the note-on is instructed to generate a tone, and if the MIDI signal is note-off, the note is generated. Instructs the start of release of the musical tone in response to the input of OFF. Also, the MID of the part set to sound on the plug-in board 2
When the I signal is input, control is performed so that the electronic musical instrument main body 1 does not generate sound. Furthermore, when the MIDI signal is a control input for part volume, effect balance, etc.,
The corresponding mixer ch is controlled by the mixer 28 or the like, and M
If the IDI signal is the input of an effect control command, DS
Microprograms and coefficients set in P29, and
The setting of the mixer channel is changed. However, when the plug-in board is an effect board, the electronic musical instrument main unit 1 does not control a control command to be handled by the effect board.

If one of the panel switches on the panel display & SW6 is operated and it is determined in step S4 that there is a factor, the factor is determined to be a SW input in step S5, and the flow branches to step S7. In step S7, the panel display & SW6
, And the SW process corresponding to the LCD buttons 1 to 3 and the buttons B1 to B8 operated at that time is performed. For example, panel display & SW
Editing is performed according to an edit command input in response to the button operation of No. 6. In this case, when the editing of the timbre data or the effect data of the timbre included in the electronic musical instrument main body 1 is instructed, the directly instructed data is changed. When an instruction to change the timbre data or effect data of the timbre provided in the plug-in board is issued, the correction data in the offset editing is sent to the plug-in board, and the CP incorporated in the plug-in board is sent.
U reflects the correction data in the corresponding parameter to generate an edited parameter.
Further, if another factor is generated and it is determined in step S4 that there is a factor, the factor is determined to be other in step S5, and the process branches to step S8. In step S8 for performing other processes, a process for controlling a time change of a tone characteristic such as a time change of a pan or a vibrato, and an automatic performance / accompaniment process by the system CPU 10 are performed. Furthermore, a process of monitoring the volume of each sounding channel for tone assignment performed when the system CPU is idle, or a process of ranking truncation may be performed.

Next, the initialization processing executed in step S2 in the CPU main processing will be described with reference to the flowchart shown in FIG. When the processing in step S1 of the CPU main processing is completed, the initialization processing is started, and in step S10, the type and specific information of the plug-in board detected in step S1 in the CPU main processing are stored in the flash ROM 11. The type of plug-in board and the specific information are compared.
Next, a slot 1 process consisting of steps S11 to S21 is executed. In step S11 in the slot 1 process, it is determined whether the plug-in boards installed in the slot 1 match by comparing the type and the specific information of the plug-in board installed in the slot 1 in step S10. You. Here, the type and specific information of the plug-in board installed in the slot 1 match, and if it is determined in step S11 that they match, it is determined that the plug-in board has not been replaced. Proceeding to step S12, it is determined whether the plug-in board installed in slot 1 has a board custom voice. Here, if the tone color data is stored in the board custom voice area where the device number DN corresponding to the slot 1 in the flash ROM 11 is “1”, the determination is YES and the process proceeds to step S13 where the tone color data is stored in the flash ROM 11. The tone color data of the board custom voice read from the area corresponding to the device number 1 is sent to the plug-in board mounted on the corresponding slot 1 and written to the RAM in the plug-in board. As a result, any tone of the board custom voice can be set as a part and sounded immediately after the power is turned on. Note that the board custom voice is a tone of the plug-in board edited by a personal computer or the like connected to the electronic musical instrument main body 1. Conventionally, it is used unless transferred from the personal computer or the like to the RAM of the plug-in board after power-on. Could not.

If it is determined in step S12 that there is no board custom voice, the processing in step S13 is skipped. Further, if it is determined in step S11 that the plug-in boards installed in the slot 1 do not match in the comparison of the type and the specific information in step S10, the plug-in board installed in the slot 1 is It is determined that the replacement has been performed, and the process proceeds to step S14. In step S14, the flash RO
It is determined whether there is a plug-in custom voice whose device number DN in M11 is “1”. In this case, if the correction data for offset editing corresponding to the device number DN of “1” is stored in the flash ROM 11, it is determined that there is a plug-in custom voice, and the process proceeds to step S18. Step S18
In the dot matrix display DP, the device number DN
Is displayed asking whether the plug-in custom voice of "1" can be deleted, and the process proceeds to step S19. In step S19, it is determined whether the correction data of the plug-in custom voice may be deleted. Here, when the LCD button corresponding to the displayed “OK?” Is operated, it is determined that the correction can be performed. Step S20
The area where the correction data of the plug-in custom voice with the device number DN of “1” in the flash ROM 11 is stored is cleared.

When "OK?" Is displayed, the Exi
When t button B2 is operated, NO is determined in step S20.
Then, the process branches to step S21, in which the sound of the plug-in board mounted on the slot 1 corresponding to the plug-in custom voice is prohibited, and the slot 1 processing is terminated. In this case, the modified data of the plug-in custom voice has not been backed up yet and it is not desired to delete the modified data, and it is considered that the user wants to back up the modified data. Then, after the slot 1 process is completed and the initial setting process is completed,
By performing the above-described save processing (quick save) by the user, the modified data of the plug-in custom voice can be backed up on the disk 8. If it is determined in step S14 that there is no plug-in custom voice, and if the processing in step S20 is completed, the process proceeds to step S15, where the tone name table and parameter name table stored in the flash ROM 11 are initialized. Be transformed into Then, step S
At 16, the timbre name information and the parameter name information are fetched from the plug-in board attached to the slot 1,
Write to the initialized table. As a result, the tone color map and the parameter name table are updated so as to correspond to the plug-in board that has been inserted into slot 1 and that has been replaced.

When the tone color map updating process in step S17 is completed, or when the process in step S13 is completed, the slot 1 process consisting of steps S11 to S21 ends, and then the process proceeds to step S22. Thus, the slot 2 process is executed. Except that the slot 2 processing is performed on the plug-in board installed in the slot 2, the processing is performed on the slot 1
The description is omitted here. Next, in step S23, other initialization processing such as clearing of various registers and setting of a default timbre of each part is performed.
As a result, the initialization processing ends, and the process returns to step S3 of the CPU main processing.

Next, the electronic musical instrument main body 1 shown in FIG.
The timbre selection event process (part 1) executed by the CPU 10 when the user performs the timbre setting operation of the main body preset voice provided in the device will be described with reference to the flowchart shown in FIG. When the basic screen shown in FIG. 4 is displayed on the dot matrix display DP, the tone color selection event process (part 1)
Can be started. Here, when one of the LCD buttons 2 to F to J is operated to select the part for which the timbre is to be selected, in step S31, the part becomes the current part P.
T. Next, a group selection operation is performed by operating one of the main body tone selection buttons B5, and either the LCD button 1 or the LCD button 2 is selected from the displayed group as described with reference to FIG. One tone is selected by the operation. In step S32, the tone color number of the selected tone color is set as the tone color number TC (PT) of the current part PT.
In this case, the selected tone color is the tone color included in the tone generator 27 of the main electronic musical instrument 1, so that "7" indicating the tone generator 27 is set as the device number DN (PT) of the current part PT in step S33. Is set. This allows
The selected main body preset timbre is set to the selected part, and the timbre selection event process (part 1) ends.

Next, when the user performs a tone selection operation of a board preset voice or a board custom voice provided on the plug-in board of the monopart sound source, or a plug-in custom voice obtained by editing these voices, the CPU 10 Will be described with reference to the flowchart shown in FIG. When the basic screen shown in FIG. 4 is displayed on the dot matrix display DP, the timbre selection event process (part 2) can be started.
Is operated to select a part for which the timbre is selected, the part is set as the current part PT in step S41. Next, the user operates the button "slot 1" or the button "slot 2" of the board tone color selection button B4 so as to select a plug-in board having the tone color to be selected. By operating the button "slot 1",
The timbre of the plug-in board mounted on the slot 1 can be selected. When the button “slot 2” is operated, the timbre of the plug-in board mounted on the slot 2 can be selected. In this case, in the initial state, either the button “slot 1” or the button “slot 2” is in the selected state, so when the button to be selected is in the selected state, it is necessary to operate the button again. There is no.

Next, when selecting the board custom voice, one of the buttons "1" to "9" of the board tone color selection button B4 or the button "D" is operated, and
Display the tone name assigned to the button.
Then, the LCD button 1 corresponding to the tone name to be selected among the tone names displayed as described with reference to FIG.
Alternatively, the user operates the LCD button 2 to select a desired tone. Further, in step S42, when the button "slot 1" is operated at the time of selecting the tone and the tone provided in the plug-in board attached to the slot 1 is selected, the slot whose device number DN is set to "1" is selected. 1
The part PTX using the tone provided in the plug-in board attached to the plug-in board is detected, and when selecting the tone, the button “slot 2” is operated to select the tone provided in the plug-in board attached to the slot 2. In this case, the in-use part PTX using the plug-in board attached to the slot 2 whose device number DN is “2” is detected.

Next, it is determined in step S43 whether the corresponding in-use part PTX has been detected. If the in-use part PTX has been detected, the flow branches to step S47. In this step S47, it is determined whether or not the part PT is currently assigned to the hand performance. If it is determined that the part PT is not currently performed in the hand, the process branches to step S50 to branch to the currently used part. It is determined whether PTX is assigned to the hand performance. Here, if it is determined that the used part PTX is assigned to the hand performance, it is prohibited to change the tone assigned to the hand performance, so the tone of the used part PTX is not changed. In step S51, the alternative timbre processing for setting an alternative timbre for the current part PT is performed. In this alternative timbre processing, if there is an alternative timbre that can be substituted for the selected timbre, the device number DN of the sound source having the alternative timbre is changed to the device number DN (P
T). Further, the tone number of the alternative tone corresponding to the tone selected by operating the LCD button 1 or the LCD button 2 is the tone number TC of the current part PT.
(PT).

In this case, the timbre of the GM (General MIDI) sound source, which is a standard tone generator specification, is selected as the substitute tone color.
The timbres of the GM sound source are 128 tones with the bank select MSB assigned to 00 and the bank number assigned to 0.
For example, when the tone color number of the tone color currently selected as the part PT is bank select MSB = 50, bank number = 0, and program change = 41, the tone color number of the alternative tone color is bank select MSB.
= 00, bank number = 0, program change = 41
Sound name "Violin". As described above, the tone color numbers of the alternative tone colors generally differ only in the bank select MSB. In the case of the configuration shown in FIG. 1, since the tone generator 27 normally has a GM sound source, the device number DN indicating the sound source of the substitute tone is set to “7”. If no alternative timbre exists, the current part PT is muted.

In step S50, the part P in use is used.
If it is determined that the TX is not a hand performance part, the tone set in the used part PTX is replaced with the current part PTX.
In step S48, the part PT in use is set.
It is determined whether there is an alternative timbre of X. Where GM
If there is a sound source or the like and there is a substitute tone, the process proceeds to step S49, and the device number DN of the sound source having the substitute tone is provided.
Is the device number DN (PTX) of the part PTX in use
Is set as Further, LCD button 1 or L
The tone number TC of the part PTX in use is the tone number TC of the alternative tone corresponding to the tone selected by operating the CD button 2
It is set as C (PTX). Further, step S4
If it is determined in step 8 that there is no alternative timbre, the flow branches to step S52 to mute the used part PTX. Furthermore, in step S47, the current part PT
Is determined to be a hand performance part, the process proceeds to step S48 to set the tone color set in the used part PTX as the current part PT, and the above-described processing is performed.

Here, if it is determined in step S43 that there is no part PTX in use, and
49 or when the process of step S52 is completed,
Proceeding to step S44, the LCD button 1 or the LCD
The timbre number of the timbre selected by operating the button 2 is set as the timbre number TC (PT) of the current part PT. Next, the process proceeds to step S45, in which the device number DN of the sound source having the selected tone color is set as the device number DN (PT) of the current part PT, and the process proceeds to step S46. In step S46, the tone color number TC (PT) set for the current part PT is notified to the plug-in board of the device number DN having the tone color so that the musical tone of the current part can be generated with the selected tone color. As a result, the timbre parameters of the timbre currently set as the part PT are set in the tone generation area of the RAM of the plug-in board. Furthermore, tone number TC (PT)
Is a plug-in custom voice with offset editing, the correction data in the offset editing is also sent to the plug-in board. Then, the timbre parameter corresponding to the selected timbre number is corrected by the correction data, and is set in the tone generation area of the RAM of the plug-in board. This makes it possible to generate a musical tone of the tone color selected for the current part PT edited by the offset editing. Then, when the processing in step S46 or step S51 ends, the tone color selection event processing (part 2) ends. In steps S48 and S51 described above, if there is an alternative timbre, the alternative timbre is set to that part. Instead, the part is muted regardless of the presence or absence of the alternative timbre. It may be.

As described above, in the tone color selection event process (part 2), when the sound source of the plug-in board is a monopart sound source, there is a part PTX in use, and the part PTX in use is a hand-held part. In the case of a part, the tone color is not assigned to the selected part PT. If the selected part PT is a hand-played part, the tone color selected unconditionally is assigned to the part PT. Thus, it is possible to perform a tone color selection operation that does not cause a sense of incongruity when hearing the musical tone of the hand performance during the performance. When the sound source of the plug-in board is a multi-part sound source, a tone can be assigned to two or more parts.
And the tone color of the plug-in board can be set to the newly selected part PT.

Next, a siphoning instruction event process executed by the CPU 10 when the user performs an operation of siphoning the timbre data of the board custom voice provided in the plug-in board into the flash ROM 11 of the electronic musical instrument main body 1 is shown in FIG. This will be described with reference to the flowchart shown in a). When the Get button B6 shown in FIG. 3 is operated, a siphoning instruction event process is activated and the dot matrix display DP indicates "OK" which means whether or not to continue siphoning.
? Is displayed. When the Go button B3 is operated here, the flash ROM as the storage destination is
It is determined whether or not the tone color data of the board custom voice is stored in 11. If the tone data of the board custom voice is stored in the flash ROM 11, the flow branches to step S53 to execute the flash RO.
The board custom voice area reserved for the specified plug-in board on M11 is cleared. In this case, the board custom voice area can be specified from the device number DN corresponding to the slot in which the plug-in board is mounted.

Then, in step S52, the board custom voice is received from the plug-in board of the specified device number DN and written in the board custom voice area for the specified plug-in board in the flash ROM 11. If the tone data of the board custom voice is not stored in the flash ROM 11 as the storage destination in step S51, the processing in step S53 is skipped and the writing processing in step S52 is performed. When the process in step S52 ends, the siphoning instruction event process ends.

Next, the CPU 10 executes a quick save operation when the user performs a quick save operation for quick saving the correction data and the like in the plug-in custom voice of the plug-in board stored in the flash ROM 11 to the disk 8 of the disk drive 7. The quick save instruction event process will be described with reference to the flowchart shown in FIG. When the save button B7 shown in FIG. 3 is operated, “quick save” is displayed on the dot matrix display DP.
Alternatively, a display screen indicating which save mode of “complete save” is selected is displayed. If "quick save" is selected here, quick save instruction event processing is activated, and in step S61, the flash ROM 11
Is stored in the disk 8 of the disk drive 7. However, when saving, the tone data of the board custom voice is excluded.
When the process in step S61 ends, the quick save instruction event process ends. The above-described quick save instruction event process is executed after the initial setting process is completed when NO is determined in step S19 of the slot 1 process in the initial setting process shown in FIG. You can save the modified data of the in-board plug-in custom voice.

Next, when the user performs a complete save operation for completely saving the tone color data of the board custom voice of the plug-in board and the correction data of the plug-in custom voice stored in the flash ROM 11 to the disk 8 of the disk drive 7. Next, the complete save instruction event process executed by the CPU 10 will be described with reference to the flowchart shown in FIG. Save button B shown in FIG.
When the user operates 7, a display screen for selecting one of the “quick save” and “complete save” save modes is displayed on the dot matrix display DP. If "complete save" is selected here, complete save instruction event processing is started, and the same processing as the siphoning instruction event processing shown in FIG. 16A is executed in step S71. Thus, the latest tone color data of the board custom voice is stored in the flash ROM 11.
Next, in step S72, tone color data and style data including correction data in the board custom voice and the plug-in custom voice stored in the flash ROM 11 are saved on the disk 8 of the disk drive 7. When the process in step S72 ends, the complete save instruction event process ends.

Next, an event-related process executed by the system CPU 10 when various events occur in the electronic musical instrument main body 1 will be described with reference to a flowchart shown in FIG. MIDI IN from terminal 17 of MIDI IN
When a signal is input, data reception event processing (MID
I / O) is activated, and receives an event of a parallel MIDI signal via the photocoupler 18 or the serial interface 19 in step S81. When performing the automatic performance / accompaniment in the electronic musical instrument main body 1, the performance event process (sequencer) is started, and the performance event generated in step S82 is received. Further, when performing with the keyboard 5, the keyboard operation event process (hand performance) is activated, and the key operation event detected in step S83 is received. These data reception event processing (MIDI
I / O), performance event processing (sequencer), and keyboard operation event processing (hand performance) can be activated at the same time. It is processed every time.

That is, after merging, step S8
The event type of the event processed in step 4 is determined. Here, if the event is data of a bank select or program change, the event type is determined to be a tone color selection event, and the process proceeds to step S85. This tone color selection event includes data of (bank select MSB + bank number + program change). In step S85, referring to the tone color map stored in the flash ROM 11, the device number DN corresponding to the data is referred to. Get. Next, in step S86, it is determined from the device number DN obtained in step S85 whether the event is a timbre selection event of the main timbre provided in the electronic musical instrument main body 1 or a timbre selection event of a timbre provided in the plug-in board. Here, if “7” is obtained as the device number DN and it is determined that the event is a timbre selection event of the main body timbre, the process proceeds to step S87 and FIG.
A timbre selection process similar to the timbre selection event process (1) shown in FIG. Here, the difference between the tone color selection process to be executed and the tone color selection event process (part 1) shown in FIG. 14 is that the tone color names not supported by the tone color selection event process (part 1) shown in FIG. It is not displayed and cannot be selected. However, in the tone color selection processing of step S87, since the tone color selected by bank select MSB + bank number + program change can be selected, an unsupported tone color is also selected.

If the obtained device number DN is set to "1" or "2" and it is determined in step S86 that the event is a tone selection event of a tone included in the plug-in board, the flow advances to step S88 to proceed to FIG. A timbre selection process similar to the timbre selection event process (2) shown in FIG. Here, the difference between the tone color selection process to be executed and the tone color selection event process (part 2) shown in FIG.
Similar to the above, in the tone color selection event process (part 2) shown in FIG. 15, unsupported tone color names are not displayed and cannot be selected. However, in the tone color selection process of step S88, bank select MSB + bank number + program Since the timbre selected by the change can be selected, an unsupported timbre is also selected. If a tone that is not supported is selected, that part will be muted.

Further, if the event type is a tempo clock event generated at the time of automatic performance / accompaniment in step S84, the flow advances to step S89 to output the tempo clock to the plug-in boards whose device numbers DN are 1 and 2. Is sent. As a result, the plug-in boards mounted in the slots 1 and 2 generate a musical tone based on the received tempo clock, so that the tone of the voice including the sequencer is selected in these plug-in boards. However, the pattern of the voice of the plug-in board can be synchronized with the performance of the electronic musical instrument body 1. Next, step S9
At 0, the tone generator 27 generates a tone for automatic performance / accompaniment based on the tempo clock.

If it is determined in step S84 that the event type is another event such as a performance event, the process proceeds to step S91 to determine whether or not the event needs to be sent out. It is determined whether processing is required. In this determination, when the event is a performance event and the part of the performance event is set on the plug-in board, it is determined that the event needs to be transmitted to the plug-in board and that the processing in the electronic musical instrument main body 1 is not necessary. If the event is a performance event and the part of the performance event is set in the main electronic musical instrument 1, it is determined that there is no need to send out the performance event and that the processing in the electronic musical instrument main body 1 is necessary. Next, it is determined in step S92 whether or not transmission is determined to be necessary. If it is determined in step S91 that transmission is required, the process proceeds to step S93 to the determined destination. Dispatches the event. If it is determined in step S91 that transmission is not necessary, step S93 is skipped and the process proceeds to step S94, in which it is determined whether processing in the electronic musical instrument main body 1 is determined to be necessary. Here, if it is determined in step S91 that the processing in the electronic musical instrument main body 1 is necessary, the process proceeds to step S95, where the processing of the event is performed in the electronic musical instrument main body 1. If it is determined that the processing in the electronic musical instrument main body 1 is unnecessary, the processing in step S95 is skipped. Step S87, step S88, step S9
When the processing of step S94 or step S95 is completed, the event-related processing executed by the system CPU 10 when various events occur in the electronic musical instrument main body 1 is completed. Such an event-related process is activated and executed every time an event occurs.

As described above, according to the present invention, the timbre name information and the timbre parameter name information are stored in a non-volatile memory such as a flash ROM. Name information and timbre parameter name information can be obtained. In this case, when the plug-in board is replaced, the stored contents of the non-volatile memory are updated collectively to a plurality of tone names and parameter names that can be specified on the plug-in board. Even when the plug-in board is replaced, the tone of the plug-in board can be used.

Further, the tone color information of the custom voice provided in the plug-in board can be backed up in the non-volatile memory of the main unit. This allows the backed-up custom voice tone information to be written to the plug-in board when the main unit is turned on, and the tone of the custom voice is immediately transferred without being transferred from the outside after the power is turned on. The information can be made available. In this case, when the power is turned on, a match between the plug-in board identification information obtained from the installed plug-in board and the plug-in board identification information stored in the non-volatile memory is detected. It may be determined that the inboard has not been replaced, and the tone color information of the backed up custom voice may be written to the plug-in board. Further, the timbre information of the custom voice stored in the non-volatile memory can be stored in an external storage medium, and the timbre information of the custom voice stored in the external storage medium can be loaded into the non-volatile memory. Have been able to. As a result, loss of the tone color information of the custom voice can be prevented.

Further, since the offset editing means for editing the tone by adding arbitrary correction data to the tone data of the tone provided in the plug-in board is provided, the tone provided in the plug-in board can be edited also in the main body. can do. This offset editing means does not change the value of the tone color parameter itself, so that it does not conflict with the editing performed externally. Also, when a tone whose offset has been edited is selected, the tone number of the selected tone and the correction data of the selected tone are sent to the plug-in board. It becomes possible to generate a tone of the tone after the offset editing corrected by the data.

Further, when the plug-in board is a monopart sound source and the tone color of the monopart sound source is selected in one part, the tone color of the same monopart sound source is specified later in another part. In this case, one part is set to prohibit sound generation (mute), and the tone color of the designated monopart sound source is set to another part. In this case, one part may be changed to an alternative tone of another sound source. This allows the user to set the timbre of a monopart sound source in another part without changing the setting of one part. Furthermore, if the tone of the mono part sound source is selected for the hand performance part, even if the tone of the mono part sound source is specified in another part, setting the tone of the mono part sound source to other parts is prohibited. are doing. As a result, the tone of the hand performance during the performance is not changed, so that the musical tone of the hand performance does not feel uncomfortable.

Further, MIDI supplied from the outside
The performance information such as signals and the performance information such as MIDI signals generated in the main body are merged and supplied to the tone generating means and the plug-in board of the main body. Thereby, the musical sound of the plug-in board can be synchronized with the performance of the main body. In this case, if the tempo clock for performing the automatic accompaniment / automatic performance on the main unit is supplied to the plug-in board, the voice including the sequencer is selected as the tone of the plug-in board for the automatic accompaniment / automatic performance of the main unit. However, the pattern performance of the voice can be synchronized with the performance of the main unit.
