Among them, the vibrato parameter information stored in the memory area FVM(K) corresponding to the musical tone generation sequence K for which the timbre selection operation was performed at this time and in the memory area FVM(KXT) corresponding to the selected timbre T is read out. This is transferred to and stored in the corresponding memory areas P■(K)(T) in the player vibrato information memory area P■. As a result, the vibrato parameter information previously stored in the memory area FVM (K '') (T ) can be copied to the memory area PVM (KXT).

Next, the operation of the electronic musical instrument configured as described above will be explained based on the flowcharts shown in FIGS. 4 to 8.

First, when the power is turned on, the CPU 6 reads tone parameter information of a standard tone from the initial tone parameter information memory area IZM of the ROM 90 in step 200 of the main routine shown in FIG. Transfer to. Then, this standard timbre parameter information is stored in the memo for each tone generation series in the memory area PBMK, S≠area PBM(S) to PBM(
P) and is transferred to the tone generator 10 in a parameter transfer process described later. As a result, each musical tone generation series SP in the tone generator 10 becomes ready to generate musical tones with standard tones immediately after power is turned on.

Thereafter, the CPU 6 clears the stored contents of the player vibrato information memory area PVM in step 201, and then determines whether the set switch 524 and the lever switch 5250 are on or off in the lever switch related processing of step 202, and only the lever switch 525 is turned on. If a new ON state is detected, the above (4)
), the light emitting diode 532 provided at the head of the lever switch 5250 is made to blink at a predetermined period to inform the player of the next tone selection operation for adjusting or setting vibrato parameter information. Instruct. On the other hand, the set switch 524 and the lever switch 52
If it is detected that both of the controllers 520 to 52 are newly turned on, the process of (B) is executed and the controllers 520 to 52 are turned on.
The vibrato parameter information (panel parameter information stored in the memory area PBM(K')) set in step 3 is transferred to the player vibrato information memory area PVM.
(, K >('r).

Thereafter, the CPU 6 determines whether or not a new tone selection operation has been performed in the tone selection related process of step 203, and if a new tone selection operation has been performed, the light emitting diode provided at the head of the lever switch 5250 is activated. Change the blinking state of 532 to a constantly lit state and press the controls 520 to 523.
to instruct the performer that the vibrato parameter information is ready to be set, and also
523 indicates by lighting the light emitting diodes 528 to 5310 that the setting of vibrato parameter information has become effective for the musical tone generation sequence for which the tone selection operation has been performed among the four musical tone generation sequences sp. , timbre parameter information regarding the timbre selected by the above timbre selection operation is stored in the timbre parameter information memory area TCM.
, and is transferred to and stored in the memory area PBMf:K) corresponding to the musical tone generation sequence K for which the above tone color selection operation was performed in the panel parameter information memory area PBM.

In this state, when the vibrato parameter report is set using the operators 520 to 523, the CPU 6 executes step 20.
In the vibrato information setting operator related processing of step 4, the vibrato parameter information set at this time is sequentially detected by scanning processing and stored in the panel parameter information memory area PBM(K) (see the processing of step (4) above).

Thereafter, the CPU 6 determines whether or not the player switch 526 or the factory switch 521 has been newly turned on in the player switch related processing of step 205, and in response to the on operation of the switch 526 or 527, the CPU 6 performs the above (C). Or perform the process in (b).

Then, in the next step 206, the other parameter information setting circuit-related processing, the parameter information set in the other parameter setting operator circuits 53 is sequentially detected by scanning processing, and the detected parameter information is stored in the panel parameter information memory area PBM ( PBM(S) ~ PBM
(P) ). Thereafter, in the information transfer process of step 207, the CPU s transfers the tone parameter information, vibrato parameter information, and other parameter information of each tone generation sequence S to P stored in the panel parameter information memory area PBM to the tone generator 1o. do.

After this, the CPU 6 repeatedly executes the processes of steps 202 to 207.

As a result, each tone generation series s-p of the tone generator 1o produces a tone that corresponds to the tone parameter information transferred from the panel parameter information memory areas PBM(S) to PBM(P) corresponding to these series, respectively. Musical tone signals of pitches corresponding to the key information KD(S) to KD(P) of the pressed keys supplied from the keyboards 1 to 4, respectively, are formed. Further, the frequency of the musical tone signal for each musical tone generation series is modulated in the vibrato effect circuit 100 in accordance with the vibrato parameter information for each musical tone generation series, and the modulated signal is supplied to the speaker 11. As a result, a vibrato sound effect corresponding to the vibrato parameter information set for each tone generation series by the vibrato adjustment operator circuit 52 is emitted from the speaker 11.

Figure 5 shows lever switch related processing step 20 in Figure 4.
2, the CPU 6 determines whether the lever switch 525 has changed from the off state to the on state in step 2020, and if it has not changed, returns to the main routine processing of FIG. 4. However, if it has changed, it is determined in the next step 2021 whether or not the set switch 524 is in the on state. As a result,
When it is detected that the set switch 524 is in the OFF state, the item display control flag signal LV is set in step 2022.
@LEDFLG1 is set to '1' and this signal is transferred to the vibrato adjustment operator circuit 52. Then, the light emitting diode 532 provided at the head of the lever switch 525 starts blinking at a predetermined period, and this blinking display This instructs the performer that the timbre should be selected by the court lady next.

On the other hand, the lever switch 525 and the set switch 524
are both on, the CPU 6 performs step 202
0 and 2021, the process proceeds to step 2023, where only the vibrato parameter information is read out from the panel parameter information memory area PBM(K) corresponding to the musical tone generation sequence K for which the timbre selection operation was most recently performed. It is transferred and stored in the memory area PVM(K)(T) corresponding to the selected tone T in the player parameter information memory area PVM(K) corresponding to the musical tone generation series K.

That is, the CPU 6 registers the vibrato parameter information stored in the memory area PBM(K) in the memory area PVM(K)(T) so that it can be used later. When this registration process is completed, the CPU 6 sets the display control flag signal LV-LEDFLG2 to IIQll, and transfers the O signal to the vibrato adjustment operator circuit 52.

Then, the light emitting diode 532 provided at the head of the lever switch 5250 changes from a blinking state to a constantly off state.

Next, in step 2025, the CPU 6 sets the display control flag signal PL-LEDFLG to "1" and transfers this signal to the vibrato adjustment operator circuit 52. As a result, the light emitting diode 533 provided at the head of the player switch 526 is always lit. When the CPU 6 finishes the process of step 2025, it returns to the tie/routine process of FIG. 4.

FIG. 6 is a 70-chart showing details of the timbre selection related processing step 203 of FIG.
) ~ TSL (P) It is determined whether any of the tone selection switches in TSL (P) has been newly turned on, and when it is detected that the tone selection switch is newly turned on, in the ninth step 2031, data is stored from the tone parameter information memory area TCM. At this time, the tone parameter information regarding the selected tone is read out, and the tone generation series KO memory area PBM (K) to which the selected tone T belongs is read out from the panel parameter information memory area PBM.
), and the display information for displaying the selected timbre T is transferred to the series-specific selected timbre display circuit TSD(K) of the tone generation series to which the selected timbre T belongs. As a result, the light emitting diode corresponding to the selected tone color T lights up in the display circuit TSD(K), and the selected tone color name is displayed.

Next, in step 2032, the CPU 6 activates the light emitting diode 532 provided at the head of the lever switch 5250.
0 display control flag signal LV-LEDFLG1
.

It is determined by LV-LED FLG2 and the blinking state (LV
-LEDFLGI = "1") (that is, if new vibrato parameter information is to be set), the display control flag signal LV/LEDFLG2 is set to 1" in step 2033, and the light emitting diode 5
32 is turned on all the time. In addition, the display control flag signal S/LEDFL corresponding to the four musical tone generation sequences S to P
The display control flag control signal (K)/LEDFLG corresponding to the musical tone generation series K to which the selected tone T at this time belongs among G to P @LEDFLG is set to "1", and the vibrato parameter information setting function in the vibrato adjustment operator circuit 52 is performed. The light-emitting diodes 528 to 5310 are turned on to indicate that the function has become effective for the tone generation series K. That is, regarding the selected timbre T in the musical tone generation series K for which the timbre selection operation was performed at this time, the operator 520
-523 indicates that the vibrato parameter information can be set by lighting any of the light emitting diodes 528-531.

On the other hand, if the light emitting diode 532 is lit, that is, if the controllers 52,0 to 523K are already in a state to start setting and setting vibrato parameter information (step 2 in (4) above has been completed). Since a new timbre selection operation has been performed again in step 2034, it is determined in the next step 2034 whether or not a new timbre selection operation has been performed in the same tone generation sequence as the previously selected timbre. As a result, if the timbre selection operation is in the same musical tone generation series, it is determined that the operation to change the selected timbre within the same musical tone generation series has been performed, and the process returns to the main routine of FIG. In this case, the timbre parameter information regarding the new selected timbre and its display information are stored in step 20.
31, the panel parameter information memory area PB has already been
There is no problem since it has already been transferred to M(K) and the series-specific tone color selection display circuit TSD(K).

However, if the newly selected timbre belongs to a musical tone generation series different from the previously selected timbre, the CPU 6 treats the vibrato parameter information setting operation for the previous selected timbre as having been cancelled, and sends a display control flag signal in step 035.

The vibrato parameter information is read from the vibrato parameter information (KXT) and stored in the panel parameter information memory area PBM(K) belonging to the same tone generation series K.

That is, if a new tone selection operation is performed in a musical tone generation series different from the musical tone generation series to which the previously selected tone belongs after the operation in Step 2 described above is completed, the player switch 52
Memory area PVM (KXT) or FVM (K) depending on the light-emitting diode 533 and factory switch 5270 head light-emitting diode 5340 of 6.
The vibrato parameter information previously stored in (T) is transferred to the panel parameter information memory area PBM (K).

On the other hand, even if it is detected that the light emitting diode 532 is in the off state as a result of the determination process in step 20320, the CPU 6 executes the process in step 2036 or 2037 via the process in step 2035.

In this case, the display control flag signal PL-LEDFLG that controls the lighting of the light emitting diode 5330 is set to the fifth flag after desired vibrato parameter information is registered in one of the player vibrato information memory areas pvM(K)(T).
It is set to 1'' by the process of step 2025 in the figure.

Therefore, if desired vibrato parameter information is registered in advance, the registered vibrato parameter information can be transferred to the memory area PBM(K) simply by performing the tone selection operation through the processing of steps 2035 and 2o36, and the performance You can change the vibrato sound effect very easily even in the middle.

FIG. 7 is a flowchart showing details of the vibrato information setting operator related processing step 204 in FIG. Since the condition is that the on operation is performed and the timbre selection operation is performed, the CPU 6 uses the display control flag signal LV-LEDF to indicate whether or not this condition is satisfied.
The determination is made based on LG2 (step 2040). As a result, if LM-LEDFLG2 = "1", the output information of the operators 520 to 523 is sequentially taken in by scanning processing in step 2041, and the next step 2042

However, when it is detected that the player switch 526 is turned on, it is determined in step 2051 whether or not the set switch 524-4 is turned on at the same time. As a result, when it is detected that only the player switch 526 has been turned on, in step 2052, the selected tone T is selected from the player vibrato information memory area PVM(K) corresponding to the musical tone generation series K to which the latest selected tone T belongs. The corresponding memory area PVM (KXT
), the vibrato parameter information stored in advance is read out, and transferred to and stored in the panel parameter information memory area PBM(K) corresponding to the tone generation sequence K. - After this, in step 2054, the CPU 5 sets the display control flag signal PL-LIiDFLG to 1", while setting FC@LEDFLG = "0", lights up the light emitting diode 533 on the head of the player switch 526,
