The present invention was made in view of the above-mentioned drawbacks, and its purpose is to provide a parameter setting device for an electronic musical instrument that allows parameter information to be used in a plurality of musical tone generation sequences to be set using only a small number of operators. .

To this end, the present invention provides a common parameter setting operator for each tone generation series, and uses this common operator to sequentially set parameter information for each tone generation series. In this case, the tone generation sequence for which the parameter setting operator is valid is determined in accordance with the operation of the timbre selection switch provided for each musical tone generation sequence, so that the tone generation sequence can be specified. The operation panel surface is further simplified by omitting the switch to perform the operation.

can be copied to

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 starts at step 200 of the main routine shown in Figure 4.
Initial tone parameter information memory area of ROM90
Read standard tone parameter information from IZM,
This is transferred to the panel parameter information memory area PBM. Then, this standard tone parameter information is written in common to memory areas PBM(S) to PBM(P) for each tone generation series in the memory area PBM, and is transferred to the tone generator 10 in the parameter transfer process described later. be done. As a result, each musical tone generation series S to P 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 the on/off states of the set switch 524 and the lever switch 525 in the lever switch related processing of step 202, and only the lever switch 525 is new. When it is detected that the lever switch 525 is turned on, in order to execute the process (A), the light emitting diode 532 provided at the head of the lever switch 525 is blinked at a predetermined period.
The player is instructed to perform the next operation of selecting a tone color for which vibrato parameter information is to be adjusted or set. On the other hand, if it is detected that both the set switch 524 and the lever switch 525 are newly turned on, the process (B) is executed and the vibrato parameter information set by the operators 520 to 523 is , (stored in the panel parameter information memory area PBM(K)) are stored in the player vibrato information memory area PVM(K)(T).

Thereafter, the CPU 6 determines whether or not a new tone selection operation has been performed in the tone selection related processing 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 525 is activated. The blinking state of 532 is changed to a constantly lit state to instruct the performer that the vibrato parameter information can now be set using the operators 520 to 523, and the operator 520 to 523
The lighting of the light emitting diodes 528 to 531 indicates that the setting of the vibrato parameter information has become effective for the musical tone generation sequence for which the timbre selection operation has been performed among the four musical tone generation sequences S to P. At the same time, the timbre parameter information regarding the timbre selected by the timbre selection operation is read out from the timbre parameter information memory area TCM and corresponds to the musical tone generation sequence K in which the timbre selection operation was performed in the panel parameter information memory area PBM. Transfer and store in memory area PBM(K).

When vibrato parameter information is set using the operators 520 to 523 in this state, the CPU 6
In the vibrato information setting operator related process of step 204, the vibrato parameter information set at this time is sequentially detected by scan processing and stored in the panel parameter information memory area PBM(K) (as described in (A) above). (see Processing).

Thereafter, the CPU 6 determines whether or not the player switch 526 or the factory switch 527 has been newly turned on in the player switch related processing of step 205, and
The process (C) or (D) above is performed in response to the ON operation in step 7. Then, in the next step 206, which is related to other parameter information setting circuits, the parameter information set in the other parameter setting operator circuits 53 is sequentially detected by scan processing, and the detected parameter information is stored in the panel parameter information memory area. Store in PBM, PBM(S) to PBM(P). After this, the CPU 6 uses the panel parameter information memory area in the information transfer process of step 207.
The tone parameter information, vibrato parameter information, and other parameter information of each musical tone generation sequence S to P stored in the PBM are transferred to the tone generator 10. After this, CPU6 goes to step 202.
Repeat steps 207 to 207.

As a result, each tone generation series S to P of the tone generator 10 has a panel parameter information memory area PBM corresponding to each of these series.
(S) ~Key information KD (S) for pressed keys supplied from keyboards 1 to 4, respectively, with a tone corresponding to the tone parameter information transferred from PBM (P) ~
A musical tone signal with a pitch corresponding to KD(P) is 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.

FIG. 5 is a flowchart showing details of the lever switch related processing step 202 of FIG.
In step 2020, the CPU 6 determines whether the lever switch 525 has changed from the OFF state to the ON state. If the lever switch 525 has not changed, the process returns to the main routine shown in FIG. 4, but if it has changed, the process proceeds to the next step 2021. At this point, it is determined 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 display control flag signal LV.
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 begins to blink at a predetermined period, and this blinking display instructs the player to select a tone next.

On the other hand, when the lever switch 525 and the set switch 524 are both in the on state, the CPU 6 goes through the determination processing in steps 2020 and 2021 and returns to step 2020.
Proceeding to step 2023, only the vibrato parameter information is read from the panel parameter information memory area PBM(K) corresponding to the musical tone generation sequence K for which the tone selection operation was most recently performed, and this is used as the player parameter information corresponding to the musical tone generation sequence K. It is transferred and stored in the memory area PVM(K)(T) corresponding to the selected tone T in the information memory area PVM(K).
That is, the CPU 6 stores 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.
Register. When this registration process is completed, the CPU 6 sets the display control flag signal LV/LEDFLG2 to "0" and transfers this signal to the vibrato adjustment operator circuit 52. Then, the light emitting diode 532 provided at the head of the lever switch 525 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 constantly lit. When the CPU 6 finishes the process of step 2025, it returns to the process of the main routine shown in FIG.

Figure 6 shows the processing steps related to tone selection in Figure 4.
203 is a flowchart showing the details of CPU
6, in step 2030, it is determined whether any of the tone selection switches in the series-specific tone color selection operator circuits TSL(S) to TSL(P) has been newly turned on, and the newly turned on operation is detected. Then, in the next step 2031, the timbre parameter information regarding the currently selected timbre is read from the timbre parameter information memory area TCM, and the memory area PBM( K)
At the same time, display information for displaying the selected timbre T is transferred to the selected timbre display circuit TSD for each musical tone generation series K to which the selected timbre T belongs.
Transfer to (K). By this, display circuit TSD(K)
, the light emitting diode corresponding to the selected tone color T lights up, and the selected tone color name is displayed.

Next, in step 2032, the CPU 6 displays the lighting display of the light emitting diode 532 provided at the head of the lever switch 525 using the display control flag signal LV.
Distinguish by LEDFLG1, LV/LEDFLG2,
If it is in a blinking state (LV/LEDFLG1="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 532 is set to "1". Change it to stay lit all the time. In addition, display control flag signals S, LEDFLG to P, and corresponding to the four musical tone generation sequences S to P are also available.
The display control flag control signal K/LEDFLG corresponding to the musical sound generation series K to which the currently selected tone T belongs among LEDFLG is set to "1", and the vibrato parameter information setting function in the vibrato adjustment operator circuit 52 is set to the musical sound generation series K. Light-emitting diodes 528-531 have become effective against
Indicated by lighting. That is, the lighting of any of the light emitting diodes 528 to 531 indicates that it is now possible to set the vibrato parameter information using the operators 520 to 523 regarding the selected tone T in the musical tone generation series K for which the tone selection operation was performed at this time. Display by.

On the other hand, if the light emitting diode 532 is lit, that is, if the vibrato parameter information has already been set using the operators 520 to 523 (at the stage where step 2 in (A) above has been completed), Since a new timbre selection operation has been performed again, in the next step 2034, it is determined whether a new timbre selection operation has been performed in the same tone generation series 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, there is no problem because the timbre parameter information and its display information regarding the newly selected timbre have already been transferred to the panel parameter information memory area PBM(K) and the series-specific timbre selection display circuit TSD(K) in step 2031. .

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 cancels the step.
Display control flag signal PL/LEDFLG at 2035
It is determined which of FC and LEDFLG is "1", and if PL and LEDFLG are "1", in step 2036, the player vibrato information memory area corresponding to the musical tone generation series K to which the new selected tone T belongs The selected tone T in PVM(K)
The vibrato parameter information is read from the memory area PVM(K)(T) corresponding to the tone generation sequence K, and is stored in the panel parameter information memory area PBM(K) belonging to the same tone generation series K. On the contrary, FC・LEDFLG
="1", the CPU 6 in step 2037 stores the factory vibrato information memory area corresponding to the tone generation series K to which the new selected tone T belongs.
Read the vibrato parameter information from the memory area FVM(K)(T) corresponding to the selected tone T in FVM(K) and store it in the panel parameter information memory area PBM(K) belonging to the same tone generation series K. let

That is, if a new tone selection operation is performed in a musical tone generation series different from the tone generation series to which the previously selected tone belongs after the operation in step 2 described above is completed,
The light is stored in advance in the memory area PVM(K)(T) or FVM(K)(T) depending on the lighting state of the light emitting diode 533 at the head of the player switch 526 and the light emitting diode 534 at the head of the factory switch 527. vibrato parameter information 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 2032, the CPU 6 executes the process in step 2036 or 2037 after passing through the process in step 2035.

In this case, the display control flag signal PL/LEDFLG that controls the lighting of the light emitting diode 533 is stored in one of the player vibrato information memory areas PVM(K).
After registering the desired vibrato parameter information in (T), it is set to "1" by the process of step 2025 in FIG.

Therefore, if the desired vibrato parameter information is registered in advance, the registered vibrato parameter information can be saved in the memory area by simply performing the tone selection operation in steps 2035 and 2036.
It can be transferred to PBM(K), and the vibrato sound effect can be switched extremely easily even during a performance.

FIG. 7 is a flowchart showing details of the vibrato information setting operator related processing step 204 in FIG. Since the condition is that 525 is turned on and the tone selection operation is performed, the CPU 6 indicates whether or not this condition is met using the display control flag signal LV/LEDFLG2.
(Step 2040). As a result,
If LV・LEDFLG2="1", the output information of the operators 520 to 523 is sequentially scanned in step 2041, and in the next step 2042, the panel of the musical tone generation series K on which the tone selection operation was most recently performed is taken in. Parameter information memory area
Stored in PBM(K).

However, if LV.LEDFLG2="0", it is assumed that the setting conditions for the vibrato parameter information are not satisfied, and the process returns to the main routine shown in FIG.

FIG. 8 is a flowchart showing details of the player switch related processing step 205 of FIG.
The CPU 6 first determines in step 2050 whether or not the player switch 526 has been turned on, and if it has not been turned on, the CPU 6 proceeds to step 2056.
Then, it is determined whether the factory switch 527 has been newly turned on. However, when it is detected that the player switch 526 has been turned on, the set switch 524 is turned on in step 2051.
At the same time, it is determined whether or not both are turned on. As a result, when it is detected that only the player switch 526 has been turned on, the musical tone generation series K to which the latest selected tone T belongs is entered in step 2052.
Player vibrato information memory area compatible with
The vibrato parameter information stored in advance is read out from the memory area PVM(K)(T) corresponding to the selected tone T in PVM(K), and is stored in the panel parameter information memory area PBM corresponding to the musical tone generation sequence K. Transfer it to (K) and store it. After this,
In step 2054, the CPU 6 sets the display control flag signal PL/LEDFLG to "1", while setting the FC/LEDFLG to "1".

LV・LEDFLG1, LV・LEDFLG2, S・
Set LEDFLG to P・LEDFLG to all “0”.
That is, the light emitting diodes 525, 528 to 53
1 are all turned off.

On the other hand, if the set switch 524 is turned on at the same time as the player switch 526 is turned on, the CPU 6 in step 2053 stores the factory vibrato information memory area FVM(K) corresponding to the tone generation sequence K to which the latest selected tone T belongs. Memory area FVM(K) corresponding to the selected tone T
Pre-stored vibrato parameter information is read from (T), and transferred to and stored in the player vibrato information memory area PVM(K)(T) corresponding to the tone generation sequence K and the selected timbre T.
That is, the vibrato parameter information stored in the memory area FVM(K)(T) is transferred to the memory area PVM.

The processes 2054 and 2055 are executed to light up the light emitting diode 533, and the light emitting diode 53
2 and 528-531 are turned off.

On the other hand, when the factory switch 527 is newly turned on, the CPU 6 transfers the vibrato parameter information stored in the memory area FVM(K)(T) to the memory area PBM(K) and stores it in step 2057. let That is, the information is stored in advance from the memory area FVM(K)(T) corresponding to the selected timbre T in the factory parameter information memory area FVM(K) corresponding to the musical tone generation series K to which the latest selected timbre T belongs. vibrato parameter information is read out and transferred to the panel parameter information memory area PBM(K) corresponding to the tone generation sequence K and stored therein. After that, in step 2058, the CPU 6 sets the display control flag signal PL/LEDFLG to "0" and FC/LEDFLG to "1" to light the light emitting diode 534 at the head of the factory switch 527, and in the next step 2059, the above-mentioned The process similar to step 2055 is executed and the process returns to the main routine.
