Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a parameter setting device for an electronic musical instrument, and is particularly directed to improving operability.

[Summary of the Invention] The present invention provides a parameter setting device for an electronic musical instrument in which a parameter setting operator of a multi-stage switch configuration consisting of a plurality of pushbutton switches is provided on the operation panel surface, and a display corresponding to each pushbutton switch is provided. When the parameter setting operator is arranged on the left side of the operation panel, the display element is arranged on the right side of the pushbutton switch, and when the parameter setting operator is arranged on the right side of the operation panel, the display element is arranged on the right side of the pushbutton switch. By arranging the elements to the left of the pushbutton switch, it is possible to make it easier for the player to see the lighting display state of the display element.

[Conventional technology]

In electronic musical instruments, various controls are arranged on the control panel to adjust the volume of musical tones and to set the depth and length of effects such as vibrato and reverb. Or by setting and operating these controls before playing,
It is possible to set parameters for musical tone control. Traditionally, analog volume controls that output analog setting signals and multi-stage switches that output digital setting signals have been used as parameter setting operators of this type.However, in electronic musical instruments that digitally process musical tone signals, digital A multi-stage switch configuration from which a setting signal can be obtained is used.

That is, as shown in FIG.
The four pushbutton switches SW1 to SW5 are arranged in a substantially straight line sequentially from the front side to the front side in the front-rear direction as viewed from the performer.
For example, an LED is placed on the right side of SW1 to SW5.
The display elements LED1 to LED5 are similarly arranged in a straight line. Push button switch SW1~
When SW5 is pressed, the display elements LED1 to LED5 corresponding to the pressed pushbutton switches SW1 to SW5 are lit up and displayed.

[Problem that the invention seeks to solve]

When the parameter setting operator 1 with this type of multi-stage switch configuration is provided on the operation panel, it is necessary to arrange the pushbutton switches SW1 to SW5 so that they can be selected and operated one by one with one finger.
The size and shape of the key tops of push button switches SW1 to SW5, the spacing between key tops, etc.
It is thought that it is necessary to select an appropriate size in relation to the size of the player's fingers to avoid pressing multiple key tops at the same time.

In particular, when setting parameters before playing an electronic musical instrument, there is operational leeway to carefully select and operate the key tops of pushbutton switches SW1 to SW5, but when setting parameters while playing an electronic musical instrument, Since quick operations are required when repairing, it is not possible to operate the key tops carefully.
It is considered necessary to provide sufficient space between the pushbutton switches SW1 to SW5.

However, in reality, the dimensions of the operation panel of an electronic musical instrument cannot be made so large, and therefore the distance between the pushbutton switches SW1 to SW5 must be narrowed.

Therefore, by narrowing the distance between the pushbutton switches SW1 to SW5, the player can press the pushbutton switches on the operation panel 3 with finger 2, as shown in FIG.
One of SW1 to SW5 (for example, switch SW
3), but because the distance between switches SW1 to SW5 is narrow compared to the player's finger 2, multiple switches (i.e., SW3 and SW5) are pressed.
4) will often result in pressing operations at the same time.

In this way, when multiple pushbutton switches are pressed, conventionally the pushbutton switch that was pressed later in time is selected preferentially (so-called last arrival priority) to determine the parameters. It was done like this.

However, even with this method, there is no guarantee that the pushbutton switch that the performer wants to press will always be pressed later, and depending on how the performer moves his/her fingers, it may be pressed first or later. Therefore, there is an inconvenience that the operation data corresponding to the pushbutton switch that one wants to press all the time cannot be outputted.

This invention has been made in consideration of the above points, and when a plurality of pushbutton switches are pressed, parameters can be set in a manner that reliably corresponds to the pushbutton switch that the performer wishes to operate. The present invention aims to provide a parameter setting device for an electronic musical instrument.

[Means for solving problems]

In order to solve this problem, the present invention provides a parameter setting operator 2 having a multi-stage switch configuration consisting of a plurality of pushbutton switches SW1 to SW5.
5, 26, 27, 32, 34, 37 are operation panels
13 and one of the plurality of push button switches
In the device, the parameter setting operator lights up when valid data is obtained from each pushbutton switch corresponding to each pushbutton switch. Multiple display elements LED1 to LED
5, and when the parameter setting operator is arranged on the left surface of the operation panel 13 as viewed from the performer, the display element is arranged at a position adjacent to the right side of the corresponding pushbutton switch. On the other hand, when the display elements are arranged on the right side surface of the operation panel 13 as viewed from the player, the display elements are arranged adjacent to the left side of the corresponding pushbutton switch.

[Effect]

When a performer sets a parameter using a parameter setting operator, the pushbutton switch pressed by the performer is displayed by lighting up the display element provided corresponding to each pushbutton switch. The performer can confirm which pushbutton switch has been operated, but especially when the parameter setting operator is arranged on the left side of the operation panel, it is recommended to arrange the display element on the right side of the pushbutton switch. On the other hand, by arranging the display elements of the parameter setting operators disposed on the right side surface to the left of the corresponding pushbutton switches, the display can be made easier to see from the performance position.

〔Example〕

An embodiment of the parameter setting device for an electronic musical instrument according to the present invention will be described in detail below with reference to the drawings.

Figure 3 shows the electronic musical instrument as a whole, with the keyboard 11
and a group of operators 12 are provided on the operation panel 13, and key information obtained in response to a pressing operation on the keyboard 11 and operator information obtained in response to the operating state of the operator group 12 are transmitted via a data path 14. CPU15
Incorporate into. The CPU 15 processes the captured data as appropriate based on the program stored in the program ROM 16 and stores it in the data RAM 17, and also sequentially reads and processes the data as necessary to the rear tone signal generation circuit (TG) 18. transfer,
A musical tone signal generated from a musical tone signal generating circuit 18 is supplied to a sound system 19 to generate a musical tone.

As shown in FIG. 4, the operation panel 13 has an upper keyboard 21 and a lower keyboard 22 on a manual keyboard panel surface 23, and separately has a pedal keyboard (not shown).

The manual keyboard panel surface 23 has a lower keyboard 22 at the front central position close to the player's performance position, and an upper keyboard 21 is provided adjacent to the right front position of the lower keyboard 22. Thus, the lower keyboard 22 The upper keyboard 21 can be played with the right hand while playing with the left hand.

A rhythm selection switch 24 and a parameter setting operator 25 with a multi-stage switch configuration for setting the volume of the rhythm sound are arranged on the left side of the lower keyboard 22, and a reverb depth control is arranged on the right side of the lower keyboard 22. Parameter setting operator 26 with multi-stage switch configuration for setting vibrato speed and vibrato speed
and 27 are arranged so as to be lined up in the left-right direction.

Further, on the left side of the upper keyboard 21, a lower keyboard timbre selection switch 31 and a parameter setting operator 32 for setting the volume thereof are arranged horizontally.

Furthermore, on the front central surface of the panel surface 23, an upper keyboard tone selection switch 33, a parameter setting operator 34 for setting the volume, and other operators 35 are arranged in order in the horizontal direction. has been done.

Further, on the right side of the panel surface 23, a pedal keyboard tone selection switch 36 and a parameter setting operator 37 for setting the volume thereof are arranged in a row in the horizontal direction.

Note that another operator 38 is provided on the left side of the upper keyboard 21.

In this embodiment, parameter setting operator 2
5, 32, 34 and 26, 27, 37 have set values of 5 bits as shown in Figures 5 and 6.
Five pushbutton switches SW1 to SW expressed in base numbers
5, and these pushbutton switches are arranged in a straight line approximately in the front-rear direction in the order of pushbutton switches SW1, SW2, SW3, SW4, and SW5 from the front to the front when viewed from the player's side. There is.
Then, the LED display elements LED1 to LED5 corresponding to each of the pushbutton switches SW1 to SW5 are arranged at adjacent positions, thus making the switches SW1 to SW5
5, the display element corresponding to the pushbutton switch that is sending valid data of logic "1" is displayed by lighting up.

When the operation panel 13 is viewed from the performer's position (i.e., the front center), the parameter setting controls 25 and 32 on the left side and the parameter setting controls 34 on the center are shown in FIG. The display elements LED1 to LED5 are arranged in the front-rear direction at positions adjacent to the right side of the pushbutton switches SW1 to SW5, while the parameter settings arranged on the right side of the operation panel 13 The display elements LED1 to LED5 in the operators 26, 27, and 37 are push button switches.
They are sequentially arranged in the front-rear direction at positions adjacent to the left side of SW1 to SW5. In this way, when the performer looks at each parameter setting operator, since the display element is located on the inside, it is possible to easily distinguish which display element is lit.

In the above configuration, the CPU 15 executes the processing procedures shown in FIGS. 1 and 2. That is, when the power is turned on, the CPU 15 starts the main routine at step SP1 in FIG.
Move on to the next step SP3.

This step SP3 includes parameter setting operators 25, 26, and 2 arranged on the operation panel 13.
By scanning 7, 32, 34, and 37 in a predetermined order, data corresponding to the operating state of each operator is sequentially imported. It is detected whether any of the button switches SW1 to SW5 has been newly pressed (this is called an on event). In step SP3, when an on-event is detected, the CPU 15 executes a subroutine related to the on-event shown in FIG.

That is, the CPU 15 moves from step SP31 to step SP32, and converts the data of the parameter setting operator including the pressed pushbutton switch into 1 byte (8 bits) of operation data.
It is imported (stored) as DATA into the storage area corresponding to the corresponding operator in the data RAM 17.

The operation data DATA imported here is the 7th
As shown in the figure, data D1 representing the operating state of the switch SW1 at the other end as seen from the performer's side is included as the least significant bit (LSB), and the operations of the switches SW2, SW3, SW4, and SW5 that are lined up in order from the front. It includes data D2, D3, D4, and D5 representing the state as second, third, fourth, and fifth bit data in this order. In this embodiment, the 6th to 8th bits are empty bits.

Thus, regarding the operation data DATA loaded into the data RAM 17, the CPU 15 determines the press operation of the push button switch intended by the performer by executing data priority processing from the lower bit side in the next step SP33. do. The determination in step SP33 is made by sequentially examining the contents of the operation data DATA starting from the least significant bit, and when a logic ``1'' bit is detected for the first time, the pushbutton switch assigned to this bit is It is determined that this was an intentional operation, and the data of this bit with logic "1" is selected as valid data.

For example, as shown in FIG. 7, if the data D3 and D4 of the third and fourth bits are logic "1",
The parameter setting operator is a push button switch.
This indicates that SW3 and SW4 have been pressed, but the CPU 15 preferentially selects the lowest bit (that is, the third bit) of data D3 as valid data and determines that switch SW3 has been operated. .

The CPU 15 makes such a judgment in the fifth
As is clear from the figures and Fig. 6, the operation data
The data in the lower bits of DATA is obtained from a pushbutton switch that is located further in position than the data in the upper bits, which means that the data from the pushbutton switch at the other end is determined to be valid data. There is. This judgment is often made when a performer attempts to select and press one of the five push-button switches with his or her fingertips.
This is based on the fact that the tip of a performer's finger is often placed directly above the key top of the switch to be pressed, rather than the pad of the finger. In other words, the first
As mentioned above with respect to Figure 0, when you press the two pushbutton switches SW3 and SW4 with your finger, the fingertip that is further away from the key top of pushbutton switch SW4 that is in contact with the pad of finger 2. This is based on the fact that the push-button switch SW3 whose key top is in contact with the other part is often the push-button switch that the performer wants to press.

After the CPU 15 selects the valid data preferentially in this manner, the CPU 15 moves to step SP34 and transfers this valid data to the musical tone signal generation circuit 18 as parameter setting data for the parameter setting operator, and then proceeds to the next step SP35. The display element of the pushbutton switch for which valid data has been obtained is turned on, and the other display elements are turned off. In this way, when the priority selection process of valid data for one parameter setting operator for which an on event has been detected is completed, the CPU 15 returns to step SP3 of the main routine in FIG. Executes event detection processing.

As a result, when the on event is detected again,
The subroutine of FIG. 1 is executed in the same manner as described above for other parameter setting operators for which this on-event has been detected. Then, all parameter setting operators 25 to 27, 3 in step SP3
When the scan and on-event detection processes of steps 2, 34, and 37 are completed, the CPU 15 executes step SP4.
, scans the tone selection switches 31, 33, 36, rhythm selection switch 24, and other operators 35, 38 arranged on the operation panel 13, and sends the processed data to the musical tone signal generation circuit 18. Send to.

Next, the CPU 15 operates the upper keyboard 21, the lower keyboard 22,
Performs a scan of each key on the pedal keyboard,
The processed data obtained as a result is sent to the musical tone signal generation circuit 18.

In this way, data can be taken in regarding the parameter setting operators, tone selection switch, rhythm selection switch, other operators, and keyboard keys provided on the operation panel 13, and the musical tone signal generation circuit 18
The cycle of sending the processed data to is completed, and the CPU 15 returns to step SP3 and repeats the above-described process.

Therefore, according to the above configuration, even if the performer operates multiple pushbutton switches, it is possible to obtain data corresponding to the pushbutton switch that the performer originally wanted to operate. Since it is no longer necessary to maintain a large distance between the key tops of each push button switch and the player's fingertips as a parameter setting operator with a multi-stage switch configuration, the overall configuration of the parameter setting device can be further miniaturized.

Therefore, according to the above configuration, when the operation panel surface is viewed from the performer's position, the display elements are arranged inside the row of pushbutton switches, making it easier for the performer to operate. This allows parameters to be set reliably to correspond to the pushbutton switch in use.

FIG. 8 shows another embodiment of this invention,
In this case, the mounting directions of the parameter setting operators on the left and right side parts of the operation panel 13 are tilted toward the player's position PX with respect to the player. That is, the parameter setting operator 32 for setting the lower keyboard volume on the left side is tilted counterclockwise compared to the case in FIG. 4, and the parameter setting operator 37 for setting the pedal keyboard volume on the right side is tilted counterclockwise.
Tilt clockwise from the case shown in Fig. 4. In this way, the performer can use the parameter setting operator 32
Or when operating 37, your finger is on the push button switch.
Since it protrudes in a direction that matches the arrangement direction of SW1 to SW5, it is possible to easily align the fingertip with the key top of the pushbutton switch that one wishes to operate.

In the above description, when valid data is preferentially selected based on the operation data of the parameter setting controller, as described above with respect to step SP33 in FIG.
I tried to perform priority selection processing by
Alternatively, the preferential selection process may be performed by dedicated hardware or by a mechanical mechanism in the parameter setting operator itself.

Further, in the above-described embodiment, the present invention is applied to an electronic musical instrument having an upper keyboard, a lower keyboard, and a pedal keyboard, but the present invention is not limited to this, and the present invention can be applied to a parameter setting device for a general electronic musical instrument. Widely applicable.

In addition, in the flowchart of FIG. 1, when the operation data DATA (FIG. 7) is taken in at step SP32, a predetermined waiting time is set, and for pushbutton switches operated during the waiting time, Operation data that includes all of these data
DATA may be obtained and processed in one data process. In this way, if the performer has a so-called "hesitation" in pressing the button, after pressing the push button switch other than the one he/she intended to press,
Even if the correct pushbutton switch is immediately pressed again, it is possible to effectively avoid the possibility that data regarding the pushbutton switch that was previously pressed by mistake will be sent to the musical tone generating device.

Furthermore, in the above embodiment, as described above with reference to FIG. 7, the data of the pushbutton switch that the fingertip touches is assigned to the lower bit, but instead, it is assigned to the upper bit. It's okay.

Further, in the above embodiment, the case where the number of push button switches of the parameter setting operator is five has been described, but the number is not limited to this, as long as there are two or more, and even if this is done, A similar effect can be obtained.

〔Effect of the invention〕

As described above, according to the present invention, when the operation panel surface is viewed from the performer's position, the display elements for the parameter setting operators on the right or left side are arranged inside the row of pushbutton switches. This makes it easier for the performer to see the display element, and as a result, the performer can reliably operate the pushbutton switch he or she wishes to operate.
