DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument operating device having excellent operability, and more particularly to a technique for guiding an operating procedure to an operator.

[0002]

2. Description of the Related Art In recent years, electronic musical instruments have various functions in addition to a function of generating a musical tone in accordance with an operation. These functions include, for example, an automatic accompaniment function and a recording function. The automatic accompaniment function is a function for automatically generating accompaniment sounds of various musics. If this function is used, the player can play the melody along with the accompaniment, so that he / she can enjoy the performance as if he or she were playing together in large numbers.

[0003] The recording function is a function of storing performance information of a player, more specifically, performance information generated by the player performing. The stored performance information can be reproduced and listened. In this case, the performer's performance can be further stored over the reproduced music. With this function, a single player can play a large number of parts sequentially and store them in a superimposed manner, so that a single ensemble can be recorded.

As described above, since the electronic musical instrument is provided with various functions, the player can enjoy various ways of enjoying that cannot be realized with a normal acoustic musical instrument.

[0005]

Since the conventional electronic musical instrument has various functions as described above, the number of switches for exerting these functions is enormous. For example, in an electronic musical instrument having an automatic accompaniment function,
In order to generate one accompaniment sound, it is necessary to set a large number of parameters such as accompaniment style, timbre, rhythm and the like. Therefore, an enormous number of switches are required to set these parameters.

Recent electronic musical instruments tend to be multifunctional.
As the functions of electronic musical instruments increase, the number of switches for exerting those functions also increases. Therefore, the operation panel of the electronic musical instrument in recent years is in a situation where switches are full. In such a situation, it is difficult to know which switch to operate to perform a desired performance,
There is a problem that the operability is poor. This problem was particularly acute for beginners.

In order to solve such a problem, basic switches such as a tone color selection switch and a rhythm selection switch, which are essential for performance, can be made larger or changed in color than other switches. Is being done.
However, there remains a problem that it is not intuitively known which switch to operate.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic musical instrument operating device which can easily know a switch to be operated and has excellent operability.

[0009]

In order to achieve the above object, the operating device for an electronic musical instrument of the present invention has a plurality of switch groups, and each switch included in each switch group is provided with a display. Operating device for an electronic musical instrument, wherein instructing means for instructing operation start, and in response to an instruction by the instructing means,
Display control means for performing a special display on a display of each switch included in the switch group to be operated.

[0010] Each switch group in this operating device includes one
One switch may be included, or a plurality of switches may be included. In each case, a display is provided corresponding to each switch. As a switch group, for example, a tone selection switch composed of a plurality of switches,
Examples include a rhythm selection switch including a plurality of switches, an accompaniment selection switch including a plurality of switches, and an automatic accompaniment start switch including a single switch.

As each switch included in the above switch group, any type of switch having on and off states such as a push button switch, a touch switch, and a seesaw switch can be used. As the display, any type of display, such as an LED or an incandescent lamp, can be used as long as it can be displayed in a different form (for example, blinking display) from a normal display form.

According to the electronic musical instrument operating device, when an operation start is instructed, the display of each switch included in the switch group to be operated by the operator is specially displayed and serves as a guide for the operator. Therefore, the operator can make necessary settings by operating the switch corresponding to the specially displayed display, so that the operator does not hesitate to select which switch to operate, and the appropriate setting can be performed at any time. Switch can be operated.

The display control means causes the display of each switch included in the switch group to be operated to perform a special display in response to an instruction from the instruction means, and any one of the switches in the switch group is pressed. In this case, a special display may be provided on the display of each switch included in the switch group to be operated next. According to this configuration, the displays of the plurality of switch groups are specially displayed one after another in the order in which they should be operated. Therefore, the operator can operate the switches in the specially displayed switch group one by one to sequentially operate the switches. All settings can be made.

In this operating device, a display is provided corresponding to each switch included in the switch group, and a special display is provided on all of these displays. One display is provided for each switch group. It is also possible to provide a plurality of displays and to display only this one special display. According to this configuration, the number of objects to be specially displayed is reduced, so that the display control is simplified.

As the instruction means in the operation device, for example, a power switch can be used. According to this configuration, when the power is turned on by the power switch, the display of the switch group to be operated first is specially displayed, so that the operator can operate the necessary switches without hesitation. When any one of the switches including the specially displayed display is operated, the display of the switch group to be operated next is specially displayed. Hereinafter, similarly, the special display is performed while the switch group is sequentially changed. Therefore, the operator can perform all switch operations necessary for the performance without omission.

As the instruction means, for example, a specially provided operation element can be used. According to this configuration, by operating the operation element, the display of the switch group to be operated first is specially displayed, and any of the switches of the switch group including the display that is specially displayed below is displayed. Each time the switch is operated, the indicator of the next switch group to be operated is sequentially specially displayed, so that the same state as when the power switch is turned on is created. Therefore,
This operator can be used, for example, when resetting various parameters of the electronic musical instrument from the beginning.

As the special display, the display on the display may be made to blink. Alternatively, the display color of the display device can be changed as the special display.
In this case, for example, L capable of displaying a plurality of colors is used as a display.
ED can be used. Alternatively, as the special display, the brightness of the display on the display device can be changed, for example, the brightness can be made higher than in the case of normal display. In this way, the display of the switch group to be operated is specially displayed, so that the operator can recognize the switch to be operated next at a glance.

Further, the operation device further comprises an operation element for suppressing the special display, and when the instruction to suppress the special display is given by the operation element, the display control means causes the display device to perform the operation. It can be configured not to perform special display. For an expert, it is not necessary to guide the switches to be operated, and the special display may rather confuse the operator. In such a case, if the operator is operated so as not to perform the special display, it is possible to provide an operation device which is easy to use even for a skilled person.

The operating device constructed as described above is used as follows. That is, when the power is turned on, first, the tone color selection LED blinks. Therefore, it is understood that the operator only has to operate one of the tone color selection switches 206 to select one tone color. Here, when one tone color is selected, the rhythm selection LED blinks next. Therefore,
It is understood that the operator only has to operate the rhythm selection switch 207 to select one rhythm (here, a beat).
Here, when one rhythm is selected, the accompaniment selection L
ED flashes. Therefore, the operator sets the accompaniment selection switch 2
It can be seen that it is only necessary to operate 08 to select one accompaniment style. Here, when one accompaniment style is selected, the blinking ends and the performance can be started. In addition,
When the keyboard device 23 is played during these operations, the blinking ends. In this case, a predetermined initial value is selected for a selection operation not performed (tone color, rhythm or accompaniment).

Next, the operation of the embodiment of the electronic musical instrument to which the operating device of the present invention is applied will be described in detail with reference to the flowcharts shown in FIGS. Each process shown in the following flowcharts is executed by the CPU 10.

(1) Main Processing (FIG. 3) FIG. 3 is a flowchart showing the main processing of the embodiment of the electronic musical instrument to which the operating device of the present invention is applied, and is started by turning on the power. When the power is turned on, first, an initialization process is performed (step S10). In this initialization process, the internal state of the CPU 10 is set to the initial state, the peripheral hardware is initialized, and the RAM 1
An initial value is set in a register, counter, flag, or the like defined in 2.

When the initialization process is completed, the tone color selection L
The ED blinking flag is turned on (step S1).
1). As a result, immediately after the power is turned on, the tone color selection LED blinks. Next, a panel event process is performed (step S12). In this panel event process, a process corresponding to the operation of each switch on the operation panel 20 is performed. The details of the panel event process will be described later.

Next, pedal event processing is performed (step S13). In this pedal event process, a process corresponding to the depression of the pedal 21 is performed. That is, when the pedal 21 is depressed, the damper flag is turned on,
When the depression is released, the damper flag is turned off.
The damper flag is referred to for determining whether to extend the sound release time in a keyboard event process described later.

Next, a keyboard event process is performed (step S14). In this keyboard event process, a sound generation process according to key depression and a mute process according to key release are performed. The details of the keyboard event process will be described later.

Next, "other processing" is performed (step S15). In the “other processing”, an automatic accompaniment processing, a MIDI processing, and the like are performed. In the automatic accompaniment process,
Processing for generating an accompaniment sound is performed based on automatic accompaniment data stored in an automatic accompaniment data memory (not shown). In the MIDI processing, the MIDI interface circuit 2
2, a process of transmitting data generated based on operations of the keyboard device 23, the operation panel 20, the pedal 21 and the like to an external MIDI device, and the like.

Thereafter, the flow returns to step S12, and the same processing is repeated thereafter. Steps S12 to S15 above
Various functions as an electronic musical instrument are realized by repeatedly executing. (2) Panel Event Processing Next, details of the panel event processing performed in step S12 of the main processing routine will be described with reference to the flowchart of FIG. This panel event processing routine is called from the main processing routine at regular intervals.

In the panel event processing, first, the timbre selection L
It is checked whether the ED blinking instruction flag is on (step S20). Then, when it is determined that the switch is on, a process of blinking the tone color selection LED is performed (step S21). In this processing, the tone color selection LED blinking flag is merely turned on. The process of actually blinking the tone color selection LED is executed by a command to turn on the LED under the condition that the tone color selection LED blinking flag is on in a timer interrupt process routine (not shown) executed at regular intervals. This is realized by alternately sending a command to turn off the light to the tone color selection LED.

Next, the tone color selection LED blink instruction flag is turned off (step S22). As a result, the flashing instruction of the tone color selection LED is controlled so as not to be issued repeatedly. Thereafter, the sequence returns to the main processing routine.

If it is determined in step S20 that the tone selection LED blinking instruction flag is off, then it is checked whether the rhythm selection LED blinking instruction flag is on (step S23). Then, when it is determined that the switch is on, a process of blinking the rhythm selection LED is performed (step S24). In this process,
The rhythm selection LED blinking flag is turned on. The blinking of the rhythm selection LED is realized in the same manner as the tone color selection LED.

Next, the rhythm selection LED blinking instruction flag is turned off (step S25). As a result, control is performed so that the blinking instruction of the rhythm selection LED is not issued repeatedly. Thereafter, the sequence returns to the main processing routine.

In the above step S23, the rhythm selection LED
If it is determined that the blinking instruction flag is off, then it is checked whether the accompaniment selection LED blinking instruction flag is on (step S26). Then, when it is determined that it is on, a process of blinking the accompaniment selection LED is performed (step S27). In this process, the blinking flag of the accompaniment selection LED is turned on. Accompaniment selection LE
The blinking of D is realized by the same method as that of the tone color selection LED.

Next, the accompaniment selection LED blinking instruction flag is turned off (step S28). As a result, control is performed so that the flashing instruction of the accompaniment selection LED is not issued repeatedly. Thereafter, the sequence returns to the main processing routine.

If it is determined in step S26 that the accompaniment selection LED blinking instruction flag is off, then a switch depression process is performed (step S29).
Details of this switch pressing process are shown in the flowchart of FIG.

In the switch pressing process, a switch selecting process is first performed (step S30). The details of the switch selection processing are shown in the flowcharts of FIGS. In the switch selection process, first, a panel scan process is performed (step S40). In this process, the CPU 1
0 sends a scan command to the operation panel 20.
Thereby, the operation panel 20 is, as described above,
Panel data is generated and sent to the CPU 10. CPU10
Stores the panel data (hereinafter referred to as “new panel data”) in a predetermined area of the RAM 12. Next, panel data read in the previous panel scan process and already stored in the RAM 12 (hereinafter referred to as “old panel data”)
Exclusive OR operation with the new panel data. This calculation result is stored in RAM 1 as an event map.
2 in a predetermined area.

Next, it is checked whether there is an ON event of the tone color selection switch 206 (step S4).
1). This is performed by checking whether or not there is a bit whose bit corresponding to each switch included in the tone color selection switch 206 of the event map and the new panel data is both "1". The presence / absence of an on event of the following rhythm selection switch 207 and accompaniment selection switch 208 is checked in the same manner.

If it is determined that there is an ON event of the tone color selection switch 206, then the tone color selection LE is set.
It is checked whether D is blinking (step S).
42). This is performed by referring to the tone color selection LED blinking flag. When it is determined that the tone color selection LED is in a blinking state, a process of stopping the blinking of the tone color selection LED is performed (step S43). In this processing, the tone color selection LED blinking flag is merely turned off. As a result, in the timer interrupt processing routine (not shown), under the condition that the tone selection LED blinking flag is off, the process of alternately sending the LED lighting instruction and the LED turning off instruction to the tone selection LED is stopped, and the blinking operation is stopped. Stopped. The method of stopping the blinking operation is the same in the following processing of stopping the blinking of the rhythm selection LED and the processing of stopping the blinking of the accompaniment selection LED.

If it is determined in step S42 that the tone color selection LED is not blinking, the process in step S43 is skipped. This is an operation when any switch included in the tone color selection switch 206 is pressed when the tone color selection LED is not blinking. Thus, even when the tone color selection LED is not blinking, the tone color can be selected.

Next, the rhythm selection LED blink instruction flag is turned on (step S44). Thus, the next time the panel event processing routine is called, the sequence of steps S20 → S23 → S24 → S25 → return is executed, so that the rhythm selection LED blinks.

Next, tone color selection processing is performed (step S45). In this tone color selection processing, the tone color number corresponding to the switch of the tone color selection switch 206 having the ON event is stored in the tone color number register. The contents of this tone color number register are used to determine tone color parameters when sounding in response to key depression. Thereafter, the sequence returns to the switch pressing process.

In step S41, the tone color selection switch 2
If it is determined that the event is not the ON event of the 06, then it is checked whether the event is the ON event of the rhythm selection switch 207 (step S46).

If it is determined that there is an ON event of the rhythm selection switch 207, it is then checked whether the rhythm selection LED is blinking (step S47). This is performed by referring to the rhythm selection LED blinking flag. And the rhythm selection LE
When it is determined that D is blinking, the rhythm selection L
A process of stopping the blinking of the ED is performed (step S4).
8). In this process, the rhythm selection LED blinking flag is turned off.

At step S47, the rhythm selection LED
If it is determined that is not blinking, step S48
Is skipped. This is an operation when any switch included in the rhythm selection switch 207 is pressed when the rhythm selection LED is not blinking. Thus, even if the rhythm selection LED is not blinking,
The rhythm can be selected.

Next, the accompaniment selection LED blinking instruction flag is turned on (step S49). Thus, the next time the panel event processing routine is called, the sequence of steps S20 → S23 → S26 → S27 → S28 → return is executed, and the accompaniment selection LED
Will blink. Next, a rhythm selection process is performed (step S50). In this rhythm selection processing, the rhythm number corresponding to the switch of the rhythm selection switch 207 having the ON event is stored in the rhythm number register. The contents of this rhythm number register are used to determine the time signature when performing automatic accompaniment. Thereafter, the sequence returns to the switch pressing process.

If it is determined in step S46 that the rhythm selection switch 207 is not an on event, then it is checked whether or not the accompaniment selection switch 208 is an on event (step S51).

If it is determined that there is an ON event of the accompaniment selection switch 208, then the accompaniment selection LE
It is checked whether D is blinking (step S).
52). This is performed by referring to the accompaniment selection LED blinking flag. Then, when it is determined that the accompaniment selection LED is in a blinking state, a process of stopping the blinking of the accompaniment selection LED is performed (step S53). In this process, the blinking flag of the accompaniment selection LED is turned off.

If it is determined in step S52 that the accompaniment selection LED is not blinking, the process in step S53 is skipped. This is an operation when any switch included in the accompaniment selection switch 208 is pressed when the accompaniment selection LED is not blinking. Thereby, even if the accompaniment selection LED is not blinking, the accompaniment style can be selected.

Next, an accompaniment selection process is performed (step S54). In the accompaniment selection process, the accompaniment number corresponding to the switch of the accompaniment selection switch 208 having the ON event is stored in the accompaniment number register. The contents of the accompaniment number register are used to determine an accompaniment style when performing automatic accompaniment. Thereafter, the sequence returns to the switch pressing process.

When there is an ON event of the accompaniment selection switch 208, the tone color selection LED blink instruction flag,
Neither the rhythm selection LED blink instruction flag nor the accompaniment selection LED blink instruction flag is turned on. Therefore, after the accompaniment selection switch 208 is pressed, the blinking of all the LEDs is stopped. In this state, since all the parameters necessary for the automatic accompaniment are set, the operator can start the desired automatic accompaniment by pressing the automatic accompaniment start switch 201.

In the above step S51, the accompaniment selection switch 2
If it is determined that the event is not the ON event of 08, the sequence returns to the switch pressing processing routine. This is because the tone selection switch 206 and the rhythm selection switch 20
This is a sequence in the case where neither the 7 nor the accompaniment selection switch 208 has an ON event.

When the above switch selection processing is completed, the sequence returns to the switch depression processing routine. And
It is checked whether there is an ON event of the operation instruction start switch 205 (step S31). This is the operation instruction start switch 2 for the event map and the new panel data.
This is performed by checking whether there is a bit whose bit corresponding to 05 is "1". The following volume switch 203 and transpose switch 204
The presence / absence of an on-event is checked in a similar manner.

Here, when it is determined that there is an ON event, the tone color selection LED blink instruction flag is turned ON (step S32). As a result, regarding the lighting of the display, the electronic musical instrument is in the same state as immediately after the power is turned on. Therefore, when the operator presses the operation instruction start switch 205 to redo the parameter setting of the electronic musical instrument, the switches to be operated are sequentially displayed by blinking display, so that the parameters necessary for performing the desired performance are set. It can be set reliably and easily.

When it is determined in step S31 that the event is not the ON event of the operation instruction start switch 205, it is then checked whether there is an ON event of the volume switch 203 (step S33). When it is determined that there is an ON event of the volume switch 203,
A volume setting process is performed (step S34). afterwards,
The sequence returns to the parameter event processing routine.

In step S33, the volume switch 203
If it is determined that the event is not an on event,
It is checked whether there is an "other switch" ON event (step S35). The “other switches” include an automatic accompaniment start switch 201, an automatic accompaniment stop switch 202, and a transpose switch 204. When it is determined that there is an ON event, "other processing" corresponding to the switch is performed (step S36). The “other processes” include an automatic accompaniment start process when the automatic accompaniment start switch 201 is pressed, an automatic accompaniment stop process when the automatic accompaniment stop switch 202 is pressed, and a key change process when the transpose switch 204 is pressed. included. Thereafter, the sequence returns to the panel event processing routine.

(3) Keyboard Event Processing Next, the keyboard event processing performed in step S14 of the main processing routine will be described with reference to the flowchart of FIG. This keyboard event processing routine
Called at regular intervals from the main processing routine.

In the keyboard event process, first, a key scan process is performed (step S60). In this key scanning process, the keyboard interface circuit 13
Key data (hereinafter referred to as “new key data”). Then, the exclusive OR operation of the key data (hereinafter, referred to as “old key data”) read from the keyboard device 23 in the previous keyboard event processing and already stored in a predetermined area of the RAM 12 and the new key data is performed. Done. The calculation result is stored in a predetermined area of the RAM 12 as a key event map. Thereafter, the new key data is stored in a predetermined area of the RAM 12 as old key data.

Next, it is checked whether or not there is an ON event (step S61). This is performed by checking whether or not a bit in the new key data corresponding to an on bit in the key event map is on.

If it is determined that there is an ON event, it is then checked whether any of the tone color selection LED, rhythm selection LED, and accompaniment selection LED is blinking (step S62). This is the tone selection LE
This is performed by checking whether any of the D blinking flag, the rhythm selection LED blinking flag, and the accompaniment selection LED blinking flag is on. If it is determined that the LED is in a blinking state, a process of stopping the blinking of all the selection LEDs (tone selection LED, rhythm selection LED, and accompaniment selection LED) is performed (step S63). This is realized by turning off the tone color selection LED blinking flag, the rhythm selection LED blinking flag, and the accompaniment selection LED blinking flag. As a result, even when the parameters are being set, once the keyboard device 23 is operated, the guide of the parameter setting operation by the blinking of the LED is stopped.

If it is determined in step S62 that the light is not blinking, step S63 is skipped. Next, arithmetic processing of a tone color parameter is performed (step S64). That is, the address of the timbre parameter to be read from the timbre data memory 11b of the ROM 11 is calculated based on the key data, the touch data, the timbre selected at that time, and the like. Next, a sound generation process is performed (step S65). That is, the timbre parameters read from the timbre data memory 11b are sent to the tone generator 14. As a result, the tone generator 14 generates a digital tone signal based on the tone color parameter and sends it to the D / A converter 25. Further, the D / A converter 25
Is sent to the sound system 26, which generates a sound based on the key operation. Thereafter, the sequence returns to the main processing routine.

If it is determined in step S61 that there is no ON event, then it is checked whether there is an OFF event (step S66). This is performed by checking whether the bit in the new key data corresponding to the bit being turned on in the key event map is turned off. Here, when it is determined that there is an off event, it is then checked whether the damper pedal 21 is on (step S6).
7). This is done by examining the damper flag.

Here, if it is determined that the pedal 21 is turned off, a mute process is performed (step S6).
8). In this silencing process, envelope data having a short release time is sent to the tone generator 14. This allows
The sound being pronounced is muted. On the other hand, if it is determined in step S67 that the pedal 21 is on, a process of reducing the release speed is performed (step S6).
9). That is, envelope data having a long release time is sent to the tone generator 14. As a result, the sound being produced is lengthened. Thereafter, the sequence returns to the main processing routine. If it is determined in step S66 that there is no off event, it is recognized that there is no keyboard event, and the sequence returns to the main processing routine.

In the embodiment described above, the blinking of the LED shifts in the order of the tone color selection switch 206 → the rhythm selection switch 207 → the accompaniment selection switch 208 to guide the operator. Is not limited to the above, and may be in any order. Further, the types of switches are not limited to the above three types, and can be applied to any type of switches.

Further, in the above-mentioned embodiment, when the selection of the accompaniment style by the accompaniment selection switch 208 is completed, the blinking of all the LEDs is stopped. After the switch is pressed, an LED provided corresponding to the automatic accompaniment start switch 201 may be displayed in a blinking manner to inform the operator that the automatic accompaniment start switch 201 should be pressed next. . Further, after the automatic accompaniment start switch 201 is pressed, the automatic accompaniment stop switch 202
May be configured to blink the LED provided in correspondence with the above, to notify the operator that the automatic accompaniment stop switch 202 should be pressed next.

In the above-described embodiment, all the LEDs included in each of the tone selection switch 206, the rhythm selection switch 207, and the accompaniment selection switch 208 are configured to blink.
6. Rhythm selection switch 207 and accompaniment selection switch 2
It is also possible to provide one display corresponding to each of 08 and blink this indicator. According to this configuration,
Since the number of objects to be blinked is reduced, the process for blinking is simplified.

Further, a blinking display suppression switch is further provided,
When this switch is pressed, it can be configured to suppress the blinking display. This is the tone selection LE
Step of turning on the D blinking instruction flag (step S1
1 and S32), a step of turning on a rhythm selection LED blinking instruction flag (step S44), and an accompaniment selection LE
Step of turning on the D blinking instruction flag (step S4
It can be realized by checking whether the blinking display suppression switch is turned on immediately before each of 9) and turning on each flag only when it is not turned on. According to this configuration, since the blinking display of the LED, which is troublesome for an expert, can be suppressed, it is possible to provide a more convenient operation device.
