2. Description of the Related Art In general, electronic musical instruments are provided with various setting items such as timbres, effects, and tempo during automatic performance in order to increase the degree of freedom of performance. By changing the parameters, different musical tones can be generated even with the same key pressing operation and hitting operation.

[0003] Such a parameter change is usually performed by providing a plurality of controls on the operation panel of the electronic musical instrument and inputting new parameters in accordance with the operation of these controls.

A conventional electronic musical instrument has a ten-key mode in which parameters are input by using a numeric keypad as an operator, and a parameter is assigned to each operator in advance, and a parameter is input by operating one of the operators. There is known an electronic musical instrument provided with a mode switching operator for switching between these two modes in accordance with an operation.

[0005]

However, in such a conventional electronic musical instrument, after the initial mode of the operation device at the time of turning on the main power is set to one of the ten-key mode and the selection mode, the mode is set by the user. Only the mode switching according to the operation of the switching operator is performed, and it may be necessary to operate the mode switching operator each time a setting item is selected to perform the mode switching, which makes the parameter input operation complicated. Was.

The present invention has been made in view of the above circumstances, and has as its object to provide an electronic musical instrument in which parameter input operations are simplified.

[0007]

According to the electronic musical instrument of the present invention which achieves the above-mentioned object, a setting item selecting means for selecting an arbitrary setting item from a plurality of setting items, and a setting item selecting means for selecting the setting item. A first mode for functioning as a numeric keypad for inputting a parameter of a setting item, and each parameter candidate is previously assigned to each setting item selected by the setting item selecting means, and is assigned by operating any of them. A plurality of operators having two modes, a second mode for inputting a parameter candidate as a parameter of the setting item selected by the setting item selecting means, and a case where the setting item is selected for each of the setting items A storage unit for storing the modes of the plurality of controls, and storing the plurality of controls when the setting item is selected. Stored in part, characterized by comprising a mode setting unit that sets a mode corresponding to the setting item selected.

In the electronic musical instrument according to the present invention, since the mode setting section is provided, the plurality of operators are automatically set to a mode suitable for the selected setting item. The operation of the mode switching operator is unnecessary, and the input operation of the parameter can be simplified.

In the electronic musical instrument of the present invention, it is preferable that the electronic musical instrument is provided with a mode switching operator for arbitrarily switching the mode set by the mode setting section according to an operation.

In such an embodiment, the user can switch from the mode set in the mode setting section to an arbitrary mode, and respect the user's preference.

In the electronic musical instrument of the present invention, the electronic musical instrument may further comprise a confirmation operator for confirming the numerical value input in the first mode as the parameter, and the second mode may be provided at the time when the operator is operated. One of the preferable modes is a mode in which a parameter candidate assigned to the operator is determined as a parameter.

In the first mode, a parameter having an arbitrary number of digits can be input by providing the above-mentioned confirmation operator. Further, in the second mode, since a parameter is input by operating only one operation element, an operation corresponding to the operation of the confirmation operation element in the first mode is unnecessary.

Further, in the electronic musical instrument according to the present invention, the setting item selecting means is configured to assign a name to each setting item in advance and select a setting item having the assigned name by operating any of the setting items. It may have a plurality of controls as items.

The keyboard 11, CPU 12, RAM 13, ROM 14, operation panel 15 and sound source 16 constituting the electronic musical instrument 1 shown in FIG. 1 are mutually connected by a bus 17.

Next, an operation panel 15 provided in the electronic musical instrument 1 shown in FIG. 1 will be described with reference to FIG.
FIG. 3 is a front view of an operation panel provided in the electronic musical instrument of the present embodiment.

The operation panel 15 shown in FIG. 2 includes a cursor key 151, ten operators on which numbers from "0" to "9" are written, an operator on which "A" is written, and " An operator group 152 including a total of 12 operators including B's, a number lock key 153, an enter key 154, an increment key 155, a decrement key 156, and a liquid crystal display panel 157 are provided. , A start button, a stop button, an edit button, and a menu button, which are not shown.

The cursor key 151 is used for the liquid crystal display panel 1.
An operator for moving a cursor displayed in 57 up, down, left and right, and has a role of selecting an arbitrary setting item from a plurality of setting items provided in the sound source 16.

The operator group 152 is operated when inputting parameters of setting items of the sound source 16 and the like.
There are two modes for inputting parameters, a ten-key mode and a selection mode. The numeric keypad mode is
In this mode, ten operators on which numbers from “0” to “9” are written function as numeric keys. In the selection mode, parameter candidates are set for each of the setting items.
In this mode, parameter candidates assigned in advance to each of the operators and assigned by operating one of the operators are input as parameters.

Here, the ROM 14 stores a correspondence table representing the correspondence between the setting items and the mode set when the setting item is selected.

FIG. 3 is a diagram showing a correspondence table stored in the ROM provided in the electronic musical instrument.

The correspondence table 141 shown in FIG.
Tempo (TEMPO), attack time (ATTAC)
K) and the release time (RELEASE) are selected, the mode is set to the numeric keypad mode, and when the tone (TONE), the reverb effect (REVERB), and the chorus effect (CHORUS) are selected, the mode is set to the selection mode. It is shown. CPU1
2 sets each operation element of the operation element group 152 to a mode corresponding to the selected setting item with reference to the correspondence table 141 stored in the ROM 14 when the setting item is selected.

The tone generator 16 included in the electronic musical instrument 1 according to the present embodiment has 12 kinds of timbres. The 12 genres include piano (Pia)
no), electric piano (E. Piano), organ (Organ), strings (String)
s), synthesizer (Synth), guitar (Guit)
ar), bass (Bass), Krabi (Clav), pad (Pad), brass (Brass), orchestra (Ohchestra), drum (Drum),
A tone group number is assigned to each of these 12 types of genres, starting from the number 0 in the stated order, and the number 11 is assigned to the last drum. In addition, one for each genre
0 different tone colors are prepared. For example, in the piano genre, there are five types of grand piano sounds and five types of upright piano sounds, for a total of 10 sounds.
There are various types of sounds. Therefore, the sound source 16
Can convert the transmitted performance information into musical tones of 120 kinds of timbres. Each of the 120 types of tone colors is assigned a three-digit tone number, and the tone group number of each tone is assigned to the second digit or more of the tone number. For example, one tone of a grand piano is assigned a tone number of "000", and another tone of a grand piano is assigned a tone number of "001". Therefore, the minimum value of the tone color number is “000” and the maximum value is “119”. Such correspondence between tone color numbers and tone colors is stored in the ROM 14.

In each of the ten operators of the operator group 152 in which the numbers from “0” to “9” are written, the tone group number is added to the number written in each of these operators. Correspondingly, a tone color whose first digit of the tone color number is 0 is assigned to each of these operators in advance. In other words, the controls marked with “0” include the tone of the piano of tone number 000,
Operators marked with “1” have the tone of the electric piano with tone number 010, those marked with “2” have the tone of the organ with tone number 020, and those marked with “3” have the same. The tone number of the strings with the tone number 030, the tone number of the synthesizer with the tone number 040 is assigned to the operator with "4", and the tone tone of the guitar with the tone number 050 is assigned to the operator with the tone number of "5". Tone number 060 is assigned to the described control.
The tone of the base, the tone with the tone number 070 is written on the operator with the tone number '7', and the tone of the pad with the tone number 080, '9' is written on the operator with the tone number 080. The brass timbres of timbre number 090 are assigned to the operators. The orchestra with tone number 100 is assigned to the operator with “A”, and the drum with tone number 110 is assigned to the operator with “B”. Such assignment of the operator group 152 to each operator is also stored in the ROM 14.

The numlock key 153 is an operator for arbitrarily switching a set mode according to an operation.
Each time the num lock key 153 is pressed once, the mode is switched to the selection mode when the numeric keypad mode is set and to the numeric keypad mode when the numeric keypad key 153 is set to the selection mode. An enter key 154 is used to confirm a numerical value input in the ten-key mode as a parameter,
An operator for instructing the CPU 12 to execute a program. In the selection mode, when any one of the operators in the operator group 152 is operated, a parameter candidate assigned to the operated operator is determined as a parameter. The increment key 155 is an operator that increases the parameter value by one each time the key is pressed once, while the decrement key 156 decreases the parameter value by one each time the key is pressed once. This is a control to be performed. The liquid crystal display panel 157 displays setting item names, input parameters, and the like.

Next, input of parameters in the electronic musical instrument 1 will be described.

First, a processing routine of the CPU 12 in inputting parameters will be described with reference to FIG.

FIG. 4 shows the CP in the parameter changing process.
9 is a flowchart illustrating a processing routine of U.

When a setting item is selected by operating the cursor key 151, first, in step S10, it is determined whether or not the selected setting item has been changed from the setting item that has been selected so far.

If it has been changed, step S20
In step, the mode is set according to the selected setting item with reference to the correspondence table 141 of the ROM 14, and the process proceeds to step S30. On the other hand, if the selected setting item is the same as the setting item selected so far, the process proceeds to step S30 without passing through step S20.

In step S30, it is determined whether or not the user has pressed down the num lock key 153. In this embodiment, the depression of the nam lock key 153 is accepted only once in one parameter change process. When the num lock key 153 is pressed,
In step S40, the mode is changed, and then in step S40.
Go to 50. That is, when the selection mode is set in step S20, the mode is changed to the ten-key mode, and
When the numeric key mode is set in step 20, the mode is changed to the selection mode, and the process proceeds to step S50. Conversely, if the num lock key 153 is not operated, this step S4
The process proceeds to step S50 without passing through 0. If the selected setting item is a setting item that accepts only numerical input in the numeric keypad mode, the numlock key 153
It is preferable that even if is pressed, the operation by the user be invalidated.

In step S50, it is determined whether or not the current mode is the ten-key mode.

If it is determined in step S50 that the current mode is not the ten-key mode, that is, if the mode is the selection mode, the process proceeds to step S60. In step S60, when the user operates one of the operators in the operator group 152, a parameter candidate assigned to the operated operator is determined as a parameter.

On the other hand, if it is determined in step S50 that the current mode is the ten-key mode, the process proceeds to step S70. In step S70, it is determined whether the currently set numerical value is 0 or more. If the currently set value is positive or 0, the coefficient "1" is temporarily stored (step S80), and if the currently set value is negative, the coefficient "-1" is stored. Is once stored (step S90).

Thereafter, when the user operates the operators of the operator group 152, the numbers described on the operated operators are recognized as numerical values in accordance with the operation sequence of the user (step S100).

Next, in step S110, it is determined whether or not the recognized numerical value is a numerical value that can be set with the selected setting item, that is, whether the recognized value is set with the selected setting item. It is determined whether or not the value is equal to or less than the maximum possible value and equal to or greater than the minimum value. If the recognition value is a numerical value that cannot be set, the process proceeds to step S130 after replacing the recognition value in step S120. That is, in step S120, if the recognition value is larger than the maximum value, the recognition value is replaced with the maximum value, and if smaller than the minimum value, the recognition value is replaced with the minimum value. On the other hand, if the recognition value is a numerical value that can be set, the process proceeds to step S130 without passing through step S120. In step S130, the recognition value is multiplied by the coefficient once stored in step S80 or step S90, and
It is displayed on the screen of the liquid crystal display panel 157 as an input value.
For example, if the current parameter of a setting item having a parameter whose numerical value that can be set is a numerical value from “−64” to “+64” is “−32”, first, the CPU 12 sets “−1”. Is once stored (step S90). Then, when the operator with “0” is pressed after the operator with “7” is pressed, C at the stage when the operator with “0” is pressed is pressed.
The PU 12 recognizes the numerical value “70” (Step S1).
00), it is determined that a numerical value that cannot be set has been input (step S110). As a result, the recognition value “70” is replaced with a numerical value “64” (step S12).
0) Further, a numerical value of “−64” is displayed by multiplying “64” by a coefficient “−1” (step S1).
30). If the parameter is to be set to a positive value in such an example, the parameter may be changed from a negative value to a positive value using the increment key 155.

When the enter key 154 is depressed, the displayed input value is determined as a parameter (step S140).

The processing routine as described above is repeated every predetermined time (for example, 10 ms).

Next, a specific example of inputting parameters will be described.

First, when the main power of the electronic musical instrument 1 is turned on, an initial screen is displayed on the liquid crystal display panel 157.

FIG. 5A is a view showing a liquid crystal display panel for displaying an initial screen when the main power is turned on.

In the initial screen, "tempo" (TEMPO)
And "TONE", that is, a tone color, are displayed, and default parameters are displayed beside each of them. When this initial screen is displayed, the cursor is initially located where the default parameters for "tone" are displayed,
"Tone" is selected. CPU 12
Sets each operator in the operator group 152 to the selection mode with reference to the correspondence table 141 shown in FIG. Also,
The default parameter of “Tone” is “Tone number 0
00 grand piano 1 ". Here, if the increment key 155 is pressed once, the parameter becomes “Electric Piano 2 of timbre number 001”, and if the Increment key 155 is pressed eight times, it becomes “Upright piano 5 of timbre number 009”, and the increment key 155 becomes When pressed again, “Tone number 00
Return to "0 Grand Piano 1". When the operator with “1” is pressed, the parameter of “tone” becomes “electric piano 1 of tone number 010”. Further, when the num lock key 153 is pressed once,
The mode is switched from the previous selection mode to the numeric mode.
In this numeric mode, when the operator with "0" is pressed once and then the operator with "9" is pressed twice, the "tone number" is displayed at the position where the "tone" parameter is displayed. "099 jazz brass" is displayed, and by pressing the enter key 154, the parameter of "tone" is determined to be "jazz brass of tone number 099".

Next, referring to FIG.
Input of (TEMPO) parameters will be described.

FIG. 5B is a view showing a liquid crystal display panel for displaying a state where “tempo” is selected on the initial screen.

The “tempo” here is a tempo at the time of automatic performance by the automatic performance function of the electronic musical instrument 1 of the present embodiment. Automatic performance by the automatic performance function is started when a start button (not shown) is pressed, and is stopped when a stop button (not shown) is pressed.
By operating the cursor key 152 on the initial screen, as shown in FIG.
When the default parameter of (TEMPO) is displayed, “tempo” is selected. The CPU 12 refers to the correspondence table 141 shown in FIG. 3 and sets each operator of the operator group 152 to the ten-key mode. In the present embodiment, in the parameter input of “tempo”, a setting is made to input a three-digit numerical value. The default parameter of “tempo” is “120” as shown in FIG. here,
When the operator with "0" is pressed once, the operator with "6" is pressed once, and then the operator with "0" is pressed again. "060" is displayed at the position where the parameter is displayed, and by pressing the enter key 154, the parameter of "tempo" is determined to be "60". Also, decrement key 1
When 56 is pressed once thereafter, the parameter of "tempo" becomes "59", and when the increment key 155 is pressed once again, the parameter of "tempo" returns to "60" again. In this embodiment, since the number of digits of the input numerical value is determined to be 3 digits, when the numerical value of 3 digits is input, the input numerical value is determined as a parameter, and the enter key 154 is pressed. May be unnecessary, but when the number of digits of the numerical value to be input is not predetermined, a parameter of an arbitrary number of digits can be input by pressing the enter key 154.

Next, the parameter input of the setting items displayed on the detailed setting screen for the tone will be described with reference to FIG.

FIG. 6 is a diagram showing a liquid crystal display panel for displaying a detailed setting screen relating to a tone.

The detailed setting screen for the tone is a screen that appears when an edit button (not shown) is pressed. Shampoo can also be performed from a menu screen described later. This detailed setting screen includes “Tone” (T
ONE), "attack time" (ATTACK),
"Release time" (RELEASE), "Reverb effect" (REVERB), "Chorus effect" (CHO
RUS) are displayed. Further, the parameter of “tone” is displayed beside the setting item name, and each parameter of the remaining setting items is displayed below the setting item name. When such a detailed setting screen is displayed, the cursor is initially positioned at the position where the "tone" parameter is displayed as shown in FIG.
"Tone" is selected. CPU 12
Sets each operator in the operator group 152 to the selection mode with reference to the correspondence table 141 shown in FIG. The parameter of “tone” can be input by performing the same operation as the operation described with reference to FIG. By operating the cursor keys 151, other setting items such as "attack time" can be selected one by one.

FIG. 6B is a diagram showing a liquid crystal display panel for displaying a screen on which a setting item of “reverb effect” is selected. The parameters of this "reverb effect" include:
"Reverb effect off", "Room" and "Studio"
And “Hall” are prepared in advance, and these parameter candidates are stored in the operator group 15.
2 is assigned to each operator. For example, each of these parameter candidates is changed from the operator with “0” to “3”.
Are assigned sequentially to the operators marked with “4”, and all the operators marked with numbers after “4” are assigned “holes”, or “7” is assigned to the operators marked with “4”. Operators assigned with “Reverb Off” are assigned to operators assigned with “8” again, and “room” is assigned to operators assigned with “9”. I have. Such an assignment to each operator is stored in the ROM 14. CPU 12
Sets each operator in the operator group 152 to the selection mode with reference to the correspondence table 141 shown in FIG.

For the “chorus effect”, a plurality of parameter candidates are prepared in advance. Each of these parameter candidates is assigned to each of the operators in the operator group 152, and this assignment is also stored in the ROM 14.

The tone generator 16 of the electronic musical instrument 1 according to the present embodiment also has other setting items.
In a setting item in which one parameter candidate is input as a parameter from among a large number of predetermined parameter candidates, rough grouping is performed on such a large number of parameter candidates, and each operation of the operator group 152 is performed. One of the representative parameter candidates among the parameter candidates belonging to each group is assigned to the child in advance, and when such a setting item is selected in the ROM 14, each operation of the operator group 152 is performed by the CPU 12. The child is stored so as to be set to the selection mode. And
When any one of the operators in the operator group 152 is operated, a representative parameter candidate is temporarily determined as a parameter, and then the increment key 155 or the decrement key 156 is pressed, so that the group is depressed within the group. Parameter can be changed freely. As a result, it is not necessary for the user to memorize a large number of predetermined parameter candidates, and the user's load in inputting parameters can be reduced. Here, it is preferable to assign only one such parameter candidate to one operator for important parameter candidates and parameter candidates with high input frequency. Note that the selection mode may be used for parameter input of a setting item having a numerical value as a parameter. For example, for a setting item in which the maximum value and the minimum value that can be set in the setting item are important, the minimum value is assigned to the operator with “0” and the maximum value is set to “9”. Assign the numbers between the minimum value and the maximum value to eight groups, and assign the numbers from "1" to "8" in order. Thus, operability can be improved. For the setting item where the input frequency of the center value of the numerical range that can be set in the setting item is high, the center value is assigned to the operator with “5”, and the other numerical values are assigned to nine groups. The parameter input time can be reduced by separately assigning each of the operators in the operator group 152 except for the operator with “5” to the group.

Finally, the selection of a setting item on a menu screen on which a plurality of setting items are displayed will be described with reference to FIG.

FIG. 7 is a diagram showing a liquid crystal display panel on which a menu screen is displayed.

The menu screen appears when a user presses a menu button (not shown). On this menu screen, 12 setting items are displayed, and when the user selects an arbitrary setting item from among these 12 setting items, each operation element of the operation element group 152 is used. Can be Each operator of the operator group 152 is assigned to each of these twelve setting items. That is, when the operator with “A” is pressed from the state of the liquid crystal display panel 157 shown in FIG. 7A, “10.
The cursor is moved to the position of the item "SAVE", and the item of save (SAVE) is selected. Thereafter, when the enter key 154 is pressed, data of the entire electronic musical instrument is stored in an external storage device (not shown). When the operator with the numeral “5” is pressed, the cursor moves to the position of the item “5. TONE” as shown in FIG. Is selected. afterwards,
When the enter key 154 is pressed, the screen jumps to a detailed setting screen for the tone shown in FIG.

As described above, in the electronic musical instrument 1 according to the present embodiment, regardless of the ON / OFF state of the nam lock key 153, each of the operators in the operator group 151 is automatically set to a mode corresponding to the selected setting item. Since the setting is performed, the input operation of the parameter can be simplified.

By providing a display for displaying the currently set mode, the operability of the user can be improved.
