DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device for setting the values of various parameters for performance operations in an electronic musical instrument or other parameters of general electronic equipment.

[0002]

2. Description of the Related Art Generally, when operating or controlling an electronic device, input values of various parameters are set. For example, in a game device, a game speed and a game score conversion rate are set as input parameters, in an audio device, a volume, a balance, a frequency band, and the like are set. In a computer device, various data input values such as spreadsheet software are set. You.

When playing an electronic musical instrument, for example, various parameters such as timbre, rhythm and tempo are set using numerical values. Conventionally, in an electronic musical instrument, in order to set a plurality of types of parameters to desired values,
A parameter selection operator that selects a parameter to be set from a plurality of types of parameters and a parameter value input operator that inputs a value of the selected parameter have been used. The parameter selection operator comprises a plurality of keys or switches corresponding to each of the plurality of parameters, and the player selects a parameter by pressing a key of a parameter to be set. The parameter value input operator includes an increment key and a decrement key or a numeric keypad. The player operates the increment key or the decrement key to increase or decrease the numerical value one by one, or directly inputs a numerical value using the numeric keypad. The value was set for the selected parameter.

In such an electronic musical instrument, a player selects a parameter using a selection operator and then inputs a value of the parameter by operating a numeric keypad or the like. In this case, for example, when inputting and specifying a three-digit value, the input by the first operation is the first digit, the second input is the second digit,
The third input was the set value of the third digit.

[0005]

However, there is no problem if the values taken by the parameters cover all the values that can be entered with the ten keys or the like (for example, 000 to 999 for a three-digit number). May not cover all the values, and exception handling in such a case is necessary. That is, if there is a valid range that can be taken as a parameter value, it is necessary to check whether the input set value is within this valid range.

In a conventional parameter setting device for an electronic musical instrument or the like, when all digits are input as parameter setting values and then an enter key (execution operator) is pressed, the input setting values become effective parameters that can be taken by the parameters. If it is out of the range, an error is displayed or input invalidation processing is performed.

However, in such a conventional parameter setting method, it is impossible to determine whether the input value is appropriate until the enter key is finally pressed after the input of the set value, and the operation may be wasted. The parameter input value setting operation was not performed efficiently.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and when setting a parameter value of a plurality of digits using an input operator such as a numeric keypad, an inappropriate value is input to the last digit. It is an object of the present invention to provide a parameter setting device of an electronic device that has been determined before and efficiently performs a setting value input operation to improve operability.

[0009]

To achieve the above object, according to an aspect of the parameter setting device of an electronic device according to the present invention, where
A multi-digit parameter setting device with a fixed effective range
Thus, an input operator for sequentially inputting the value of the plurality of digits, a currently input digit, a currently input value, and a value input to a digit higher than the currently input digit. The value of the digit below the currently input digit is automatically set
And an input control means for constant.

In a preferred embodiment, the input value of a plurality of digits has a valid range, and the input control means controls the input based on the valid range for each digit input operation.

[0011]

In order to specify the value of each digit of a multi-digit parameter setting value, when inputting a parameter value, the currently input digit and its value are checked to determine whether or not it is appropriate. Not only that, it is checked whether the value is appropriate in relation to the upper digit, so that fine control can be efficiently performed in a short time. More books
In the invention, since the parameter has a predetermined effective range,
Within this effective range, the currently entered digit and its upper digit
Based on the value, automatically enter the value of the lower digit not entered yet
Can be determined.

On the panel, a segment LED display 16 for displaying set values of various parameters, an increment key 17 and a decrement key 20 for increasing or decreasing input values by one, a numeric keypad 18 for inputting numerical values, a rotary A rotary encoder 19 connected to a volume or the like to control various musical tones, a parameter selection operator 22 including selection switches for selecting performance parameters such as timbre, rhythm, and tempo, and a selection corresponding to each selection switch. An LED 21 for displaying a parameter is provided. In addition, a power switch, a volume switch, other various selection switches, a control switch, and the like are provided on the operation panel.

FIG. 3 shows the flow of the performance operation processing of the electronic musical instrument according to the present invention. A main routine 50 that performs all processes necessary for performance from power-on is a process of transmitting a key-on / off signal, a key code, and the like to the tone generator 8 in response to a pressed / released key detected by the detection circuit 4. A keyboard processing routine 51, a panel processing routine 52 for detecting pressing of various switches and keys on the panel and performing various arithmetic processing based on the pressing, and other processing, for example, a performance processing data stored in the ROM 12 is transmitted to the panel processing routine 52. In RAM
There is provided a routine 53 for reading at a tempo corresponding to the tempo value stored in 11 and performing an automatic performance.

FIG. 4 is a flowchart for setting a tone color number according to the present invention. The player first presses a tone button from among the parameter selection controls 22 (FIG. 2) on the panel. Thus, the subroutine shown in FIG. 4 is started in the panel processing 52 of FIG. In this embodiment, the timbre number is represented by three digits, from 000 to 12
Values up to 7 are assumed.

First, at step 54, an operation for inputting a numeric key is waited. When a numeric key is input, the input digit is determined. If it is the first input operation, it is determined to be the first digit, and the flow proceeds to step 56.

In step 56, the first digit input value is determined. Since the valid range of the tone number is from 000 to 127, only 0 or 1 is valid in the first digit,
If any other value is entered, ignore that value.
That is, step 5 is performed without performing any processing on the input value.
Returning to step 4, steps 54, 5 until a valid value is entered
5. Repeat steps 5 and 56. If 0 or 1 is entered,
The input value is set as the first digit (step 57).
According to the input value, the LED display 16 (FIG. 2) displays "0-
"-" Or "1--" is displayed (step 58).

When the first digit is set to valid, the next numeric key input is awaited (step 54). If there is a numeric key input, the second digit is determined in step 55, and step 59 is performed.
Proceed to. In step 59, the value of the first digit is determined. If the value is 0, the input value of the second digit is set as a valid input value as it is (step 61). If the first digit is 1, the value is set when 0, 1 or 2 is input (step 61), and when 3 to 9 is input, it is ignored until a valid value is input. Step 54, 5
5, 59 and 60 are repeated. When an input value is set in the second digit, “00-” to
"12-" is displayed (step 62).

When the second digit is set and input valid, the next numeric key input is waited for (step 54). When the ten key input is made, the third digit is determined in step 55 and the process proceeds to step 63. In step 63, the value of the first digit is determined. If the value is 0, the input value of the third digit is set as an effective value as it is (step 64). As a result, a valid three-digit tone color number is set, and this tone color number is sent to the tone generator 8 (step 65). This tone number setting value is LED
The message is displayed on the display (step 66), and the process returns to the main routine.

Thus, when a valid three-digit value is input, the three-digit input value is automatically set as the tone number without performing the operation of the enter key, which is conventionally performed, and the like.
The tone generator 8 generates a tone signal of a tone of a tone number set according to a keyboard operation.

On the other hand, if the value of the first digit is 1 in step 63, the flow advances to step 67 to determine the value of the second digit.
Since the effective range of the tone setting value is 000 to 027, 2
If the digit is 0 or 1, the input value of the third digit is set as an effective value as it is (step 64). 2nd digit is 2
In the case of, if the third digit is a numerical value from 0 to 7, it is set as a valid value as it is (step 64), and 8 or 9
In the case of (2), the steps 54, 63, 67, and 68 are repeated until a valid value is input, ignoring it.

As described above, a three-digit tone number is set.

FIG. 5 is a flowchart for setting a tempo value from among the parameters according to the present invention. The tempo value is three digits and takes a value from 040 to 240. As in the case of the tone number setting described above, the player presses the tempo switch on the panel to select the tempo setting, and the set value input routine is started.

As in the case of setting the tone color, input of a numeric key is waited for (step 69), and the input digit is determined (step 70). In the case of the first digit input, the process proceeds to step 71,
If 0, 1 or 2 has been input, it is set and displayed as an input value as it is (steps 72 and 75). 4 in first digit
If 9 are input, these are numerical values that cannot be taken as the first digit, and are regarded as numerical values of the second digit.
０09 and displayed (steps 73 and 74). 1
If the third digit is 3, it is ignored. That is, the process returns to step 69 without performing any processing on the input value, and repeats steps 69, 70, and 71 until an appropriate value is input.

In the case of the second digit input, 1 is set at step 76.
The set value of the digit is determined, and the flow is divided according to the set value. If the first digit is 0, ignore 0 to 3 in the second digit and
In the case of ９9, this is set and displayed as the second digit input value (steps 78 and 79). If the first digit is 1, the input value of the second digit is set and displayed as it is (step 78,
79). If the first digit is 2, the input value is determined in step 80. If the second digit is 0 to 3, the setting is displayed as it is (steps 78 and 79). If the second digit is 4, the setting value is displayed. Since only up to 240 can be taken, 0 is set in the third digit (step 81), 240 is displayed as the tempo value (step 82), this tempo value is stored in the RAM 11 (step 83), and the process returns to the main routine. . Steps 69, 70, 76, and 80 are ignored when the first digit is 2 and 5 to 9 are input in the second digit until an appropriate value is input.
Is repeated.

When the setting of the second digit is completed and the third digit is set, the input value is set as the third digit as it is (step 84), and the three digit tempo set value is displayed (step 85). ), And stores the tempo value in the RAM 11 (step 83), and returns to the main routine.

As described above, a tempo value having an effective range from 040 to 240 is set.

In the above embodiment, the timbre or the tempo is selected as the parameter to be set. However, the present invention can be applied to rhythm and other parameters.
In the above-described embodiment, numerical values are input using the numeric keys.
As long as the parameter is specified by a value of a plurality of digits, a character may be input with an alphabet key or the like (for example, AB or KS for a two-digit character). Further, an effective range in which the value of the parameter can be taken may be displayed. Also,
If the input value is ignored or another digit is forcibly fixed, the effect may be notified visually or by voice.

Although the above embodiment has been described with reference to an electronic musical instrument, the present invention is not limited to an electronic musical instrument, but can be applied to general electronic devices such as game devices, audio devices, and computer devices including various electronic control devices.

[0030]

As described above, in the parameter setting device for electronic equipment according to the present invention, when a value of a plurality of digits is input, the validity of the value is determined according to the input digit and the input value. In addition to discriminating, the input value is controlled based on the effective range for each digit, taking into account the set value of the upper digit, so simply check whether the input value is appropriate only for the current input digit As well as the current input value is checked for suitability in relation to the digit above it,
Further, detailed control is efficiently executed in a short time.
This makes it possible to quickly and accurately determine a value outside the valid range during the input operation, to reduce waste of subsequent operations, or to set the input value as a valid input value for another digit, thereby improving the efficiency of the input setting process. Operability of parameter setting is improved.
