I am supposed to do it.

The left and right pedal function execution units 8 and 9 execute the functions assigned when the left and right pedals 10 and 11 are depressed, and are provided for each of the left and right pedals. The functions of the pedal function executing units 8 and 9 are realized by a program.

The ROM 200 stores tone color data and various other fixed data in addition to the program for operating the CPU 100 described above. The left and right pedal function data directly related to the present invention is stored in the left and right pedal function data storage section 7 of the ROM 200.

The left and right pedal function data storage section 7 provided on the ROM 200 stores functions that can be assigned to the left and right pedals 10 and 11. In the present invention, unlike the prior art, the function data assigned to the pedals are collectively stored in one memory, and the pedals can be assigned to the left and right pedals.

In the RAM 300, a work area of the CPU 100, various registers for controlling the electronic musical instrument, counters, flags and the like are defined, and necessary data stored in the ROM 200 is transferred and temporarily stored. It has a data area to be stored.

Further, a plurality of registers in which data necessary for sound emission corresponding to the state of each key and switch of the operation panel 5 are set, and each tone generation circuit of the tone signal generator 4 is assigned to an unused channel. The assigner memory that stores data, the storage area that stores performance information, etc.
It is provided in 300.

The pedal function buffer 14 for storing the allocation of pedal functions directly related to the present invention is the RAM 3
00.

The keyboard 1 is used for designating a musical sound to be generated, and is composed of a plurality of keys and a key switch which opens and closes in association with key pressing / release operations of these keys. The key depression / key release operation of the performer is detected by the key depression detection unit 2, and the signal detected under the control of the CPU 100 is supplied to the tone generation channel allocation unit 3.

The key-depression detection unit 2 detects the key-depression / key-release actions of the player, that is, the on / off state of the key, and transmits the detected on / off state to the sound generation channel assigning unit 3 together with the key number. is there. The CPU 100 stores the on / off information of this key in the RAM 300.

Various switches and indicators such as a tone color selection switch, a mode designation switch, a melody selection switch, and a rhythm selection switch are provided. The automatic performance switch 5A and the system switch 5C are provided on the operation panel 5.

The set / reset state of each switch of the operation panel 5 is detected by the panel scan circuit, and the data concerning the set state of the switch detected by the panel scan circuit of the operation panel 5 is CP.
It is stored in the RAM 300 under the control of U100.

The pedal device 10 is provided with, for example, a damper pedal, a soft pedal, a sostenuto pedal, etc. according to the type of electronic musical instrument, and the on / off states of these pedals are detected by the respective pedal function executing units 8 and 9. To be done.

The tone generation channel assigning section 3 is provided with a key depression detecting section 2.
Also, the internal sound source sent from each of the pedal function executing units 8 and 9 is assigned to a predetermined sounding channel. The musical tone information from the pronunciation channel assigning unit 3 is
It is supplied to the tone signal generator 4.

The tone signal generator 4 reads the tone waveform data and envelope data corresponding to the signal output from the CPU 100 from the waveform memory, adds the envelope to the read tone waveform data, and outputs the tone signal. .

The tone signal output from the tone signal generator 4 is supplied to the amplifier 12 through a D / A converter (not shown). For this reason, a waveform memory (not shown) for storing waveform data and envelope data is connected to the tone signal generator 4.

The amplifier 12 amplifies the analog tone signal supplied from the tone signal generator 4 through the D / A converter with a predetermined gain. The output of the amplifier 12 is supplied to the speaker 13.

The speaker 13 converts the analog musical tone signal as an electric signal sent from the amplifier 12 into an acoustic signal. That is, the musical tone is emitted according to the generated musical tone signal.

Next, the assignment of pedal functions to the pedal function buffer 14 will be described with reference to FIG.

FIG. 4A shows an example of the function assigned to the pedal. The pedal functions assigned to the pedals include software, damper, rhythm start /
There are stops and rhythm intro / ending.

As shown in the figure, a function number is assigned to the function to be assigned to the pedal, and the function number is assigned to the pedal function buffer 14.
The function is assigned to the pedal by storing it in the memory area of the corresponding pedal. The function number is used to facilitate the storage and identification of the function.

Therefore, as shown in FIG. 4B, the function to be assigned to the pedal is stored in the pedal function buffer 14 provided on the RAM 300 in the memory area for the left and right pedals by the function number of each pedal. To be done.

As a result, when the pedals 10 and 11 are pressed during the performance, the pedal function executing unit 8 or 9 of the corresponding pedal reads the function number of the pedal assigned to the pedal from the pedal function buffer 14 and performs the function. The function corresponding to the number is read from the left and right pedal function data storage section 7 and sent to the tone channel assigning section 3 and the tone signal generating section 4 for sounding.

As described above, according to the present invention, the left and right pedal function data 7 and the left and right pedal function assigning section 6 are integrated unlike the prior art (see FIG. 8), so that the functions that can be assigned to the pedal are left and right. It can be assigned to any pedal.

Therefore, according to this structure, the same function can be assigned to both pedals.

FIG. 5 is a flowchart of the main routine showing the operation of the electronic musical instrument of this embodiment. The operation of the electronic musical instrument of this embodiment will be described below with reference to FIG.

First, when the power switch provided on the operation panel 5 is turned on or the reset switch is depressed, initialization processing is performed (step S1).
1).

In this initialization processing, the registers inside the CPU 100 and the registers defined inside the RAM 300 are initialized, the predetermined data and programs stored in the ROM 200 are moved to the RAM 300, and further, the tone color is set. This is processing such as initializing the pointer and determining the initial tone color.

Then, a panel scan process is performed (step S12). In this panel scan processing, the presence / absence of an event is determined based on the data detected by the scan circuit of the operation panel 5, and on / off information of each switch is created based on the determination result and stored in the RAM 300.

Then, the various functions are assigned to pedals (step S13). The operation of assigning various functions to the pedal will be described in detail in the explanation of FIG.

When the assignment of various functions to the pedal is completed, the pedal scan is subsequently performed (step S1).
4).

The pedal scan process is a process of reading the data on / off of the pedals 10 and 11 detected by the left and right pedal function execution units 8 and 9 and setting it in the pedal function buffer 14, which is the same as the old pedal function buffer. By comparing the contents of the pedal function buffers, a pedal event buffer in which parts corresponding to the operated pedals 10 and 11 are turned on or off is created.

Then, the fetched data is searched to check whether or not there is a pedal event, that is, whether or not there is a pressing or releasing operation (step 15). If there is no pedal event here, there is no need to process anything, so the process skips to step S17.

On the other hand, when it is determined that there is a pedal event, the pedal function is executed (step S16). This is a process for executing the function assigned to the pedals 10 and 11.

That is, when there is an on event of the pedals 10 and 11, the function number of the function assigned to the pedal is checked, the function corresponding to the function number is read from the left and right pedal function data section 7, and a predetermined area of the RAM 300 is read. Store and prepare for pronunciation.

Then, a key scan process is performed (step S17). In this key scan processing, data regarding the key depression state of the keyboard 1 detected by the key depression detection unit 2 is read,
This is a process of setting in the new key buffer, and by comparing the contents of the old key buffer and the new key buffer, the key event buffer in which the part corresponding to the operated key is turned on or off is created.

Then, the fetched event buffer is searched to check whether or not there is a key event, that is, whether or not there is a key depression or key release operation (step 18). If there is no key event here, there is no need to process anything, so the process skips to step S22.

On the other hand, when it is determined that there is a key event, it is checked whether or not the event is an on event (step S19). If it is an on event here, a predetermined sounding process is performed (step S20), and the process proceeds to other processes in step S22.

That is, the musical tone signal generator 4 is driven, and a digital musical tone signal is output via a predetermined channel and supplied to the tone generator system. This digital tone signal is D /
The analog tone signal is converted by the A converter, amplified by the amplifier 12, and emitted from the speaker 13.

On the other hand, when it is determined in step S19 that the event is not the on event, that is, the key release event, the mute processing is performed (step S21). This mute processing is processing in which the CPU 100 sends predetermined control information to the musical sound signal generation unit 4 to erase the musical sound currently being sounded.

For example, if the pedal information is off, a predetermined release data is sent, the envelope is quickly converged to "0", and the sound is cut off. Then, it progresses to Step S22 and performs other processing (Step S22).

In the "other processing", processing according to the designation of the switch detected by the switch event processing, the keyboard event processing, etc., for example, the switch event for the tone color changing processing, the volume changing processing, the rhythm selecting processing, etc. is processed. It is a thing.

Next, step S of the main routine of FIG.
Regarding the operation of assigning the pedal function of 13 to the pedals, FIG.
Will be described with reference to.

In assigning the pedal function to the pedal, it is first checked whether or not there is a panel event, based on the result of the panel scan performed in the process of step S12 of the main routine described above (step S31).

If there is no change in the setting of the panel switch, there is no change in the setting of the assignment of the pedal function to the pedal, so that the process directly returns to the main routine.

On the other hand, if the panel switch setting is changed in step S31, then the system switch 5
It is checked whether or not C is turned on (step S3).
2). That is, it is checked whether the system switch 5C is set in the system setting mode.

If the system switch 5C is not set to the system setting mode, it is not necessary to set the system, and the process branches to perform other panel processing other than the system setting (step S34). That is, processing other than the system such as tone color change and effect ON / OFF is performed, and the process returns to the main routine.

On the other hand, when the system switch 5C is set to the system setting mode, the system mode is selected (step S33).

The selection of the system mode is the selection of the mode to be set, such as the assignment of the pedal function and the MIDI setting. The page is changed based on the display screen displayed on the LCD to select the item to be set and the cursor or This is a process that is set by the value switch, and an example of the processing procedure is illustrated in the example of the operation of FIG. 7.

Next, it is checked in step S33 if the left pedal function setting mode is selected (step S35).

If the left pedal function setting mode is selected, the process proceeds to step S36 to set the left pedal function. That is, in the procedure described with reference to FIG. 7, the left pedal is set to a function desired to be assigned to the pedal, such as software or rhythm start / stop, and the process returns to the main routine.

On the other hand, if the setting mode for the function of the left pedal is not set, it is subsequently checked whether or not the setting mode for the right pedal function is selected (step S37).

If the right pedal function setting mode is selected, the process proceeds to step S36, the right pedal function is set as in the case of the left pedal, and the process returns to the main routine.

If the right pedal function setting mode is not set in step S37, other system settings are made (step S38). That is, system functions other than pedal function settings such as MIDI channel settings are set, and the process returns to the main routine.

In this way, the pedal 1 having the pedal function is
Assignments to 0 and 11 are made.

Next, a procedure for assigning pedal functions to pedals will be described with reference to FIG.

As shown in FIG. 7A, in addition to the display screen, the operation panel 5 is provided with an automatic performance switch 5A and a system switch 5C, as well as a cursor switch, a value switch and the like.

The system switch 5C is a push-down switch, and when the system switch 5C is pushed down, the system can be set on the LCD screen. To assign the pedal function of the present invention, the system switch 5C is pressed to display a display screen, and the system setting is performed with reference to the screen.

The cursor switch is used to select an item whose setting value is to be changed, and the cursor is moved between items on the screen by operating the switch.

The value switch is a switch for changing the value of the item with the cursor. For example, as shown in FIG. 7B, when the value switch is operated in the state where the cursor is on the system mode page, the page of the screen changes and it becomes possible to select another system mode.

The assignment of the pedal function is performed, for example, in FIG.
As illustrated in (d), when the value switch is operated while the cursor is in SOFT, for example, DAMPE
The display changes to R or RHYTHM, and the pedal function displayed in the title column is set.

In this way, according to the present invention, it is possible to assign the same function to a plurality of pedals.

Although the present embodiment has been described by taking the case where the left and right pedals are provided as an example, the present invention is not limited to this.

Further, in the present embodiment, the allocation to the pedals having different functions such as software and rhythm intro has been described as an example.
The present invention is not limited to this.

For example, some fill-in patterns are prepared and stored in the left and right pedal function data storage section 7, and a function number is also added to the data, and the fill-in function number to be assigned to the pedal is stored in the pedal function buffer 14. By storing, fill-in can be assigned to the pedal.
