JPH096354A - Parameter setter of electronic apparatus - Google Patents

Abstract

PROBLEM TO BE SOLVED: To improve operability by providing a parameter setter with an input control means which judges and sets input digits in accordance with inputted values, thereby judging inadequate values before the values are inputted down to the final digit. SOLUTION: To set, for example, timbre number, an operator first pushes the buttons of the timbre among parameter selective operation elements 22 on a panel. Since the effective range of the timbre numbers include 000 to 127, the input of a ten key 16 is effective at a 0 or 1 alone for the first digit. The input value is neglected if the values exclusive of this value are inputted. The input value is set as the first digit if the 0 or 1 is inputted. The '0--' or '1--' is then displayed on an LED display 16 according to this input value. If the value of the first digit it 1, the input value of the third digit is set as it is as the effective value in the case of the 0 or 1 of the second digit. If the second digit is 2, the numerical values from 0 to 7 are set as the effective values as they are when the third digit is these numerical values, and 8 or 9 is inadequate and is, therefore, neglected and the operation is waited until the effective value is inputted.

Description

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 playing operations in electronic musical instruments 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 game devices, game speed, game score conversion rate, etc. are set as input parameters, in audio devices volume, balance, frequency band, etc. are set, and in computer devices, various data input values such as spreadsheet software are set. It

When playing an electronic musical instrument, for example, various parameters such as tone color, rhythm and tempo are set using numerical values. Conventionally, in electronic musical instruments, in order to set a plurality of types of parameters to desired values,
A parameter selection operator for selecting a parameter to be set from a plurality of types of parameters and a parameter value input operator for inputting the value of the selected parameter have been used. The parameter selection operator is composed of a plurality of keys or switches corresponding to each of the plurality of parameters, and the performer selects a parameter by pressing the key of the parameter to be set. The parameter value input operator consists of an increment key and a decrement key or a numeric keypad. The performer operates the increment key or decrement key to increment or decrement the numeric value by one, or to input the numeric value directly with the numeric keypad. The value was set for the selected parameter.

In such an electronic musical instrument, the performer selects a parameter with a selection operator, and then inputs the value of the parameter by operating a ten key or the like. In this case, for example, when inputting and specifying a 3-digit value, the first input is the first digit, the second input is the second digit,
The third input was the set value for the third digit.

[0005]

However, there is no problem if the values of the parameters cover all the values that can be input by the ten-key pad (for example, 000 to 999 for a three-digit numerical value). However, there are cases where all values are not covered, and exception handling in such cases is necessary. That is, if there is a valid range that can be taken as the value of the parameter, it is necessary to check whether the input set value is within this valid range.

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

However, in such a conventional parameter setting method, it may not be possible to determine whether or not the input value is valid until the input key is finally pressed after inputting the set value, and the operation may be wasted. Yes The parameter input value setting operation was not performed efficiently.

To give a more concrete example, for example, when the number of digits that can be taken by the parameter numerical value is smaller than the number of input value displayed digits (for example, when a two-digit parameter numerical value is input to a three-digit display panel), the conventional It was necessary to input all three digits by setting the input value of the first digit to 0 and then inputting the parameter numerical value of two digits.

However, in such a case, if the setting is completed by the input operation of only the parameter numerical value having a small number of digits, the input operation becomes efficient, the intention of the operator is reflected accurately and promptly, and the operation feeling is also improved. .

The present invention has been made in view of the above-mentioned drawbacks of the prior art. When an input operator such as a numeric keypad is used to set a parameter value of a plurality of digits, an improper value is input up to the last digit. Providing a parameter setting device for electronic devices that makes it possible to set necessary parameter values without inputting all digits depending on the parameter set value by efficiently performing the set value input operation by making a determination in advance. With the goal.

[0011]

In order to achieve the above object, a parameter setting device for electronic equipment according to the present invention is provided with an input operator for sequentially inputting a value of a plurality of digits, and an input operator. It is characterized by further comprising input control means for determining an input digit of the value based on the determined value and setting the value input by the input operator to the determined input digit.

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 this valid range for each input operation of each digit.

[0013]

When the value of each digit of the parameter setting value of a plurality of digits is designated, the input digit of this input value is automatically determined based on the input value.

The main routine 50, which performs all the processing required for performance from power-on, performs processing such as sending a key on / off signal, a key code, etc. to the tone generator circuit 8 in response to the key release detected by the detection circuit 4. A keyboard processing routine 51, a panel processing routine 52 that detects various switches and keys pressed on the panel and performs various arithmetic processing based on the detected pressure, and other processing, such as performance data stored in the ROM 12, is processed by the panel processing routine 52. And RAM
A routine 53 for reading out at a tempo according to the tempo value stored in 11 and performing an automatic performance is provided.

FIG. 4 is a flow chart for setting a tone color number based on the technique related to the present invention. The performer
First, a tone color button is pressed from the parameter selection operator 22 (FIG. 2) on the panel. As a result, the subroutine shown in FIG. 4 is activated in the panel processing 52 of FIG.
In this example, the timbre number is represented by 3 digits and takes a value from 000 to 127.

First, in step 54, the input operation of the ten keys is waited for. When the numeric keypad 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 advances to step 56.

At step 56, the first digit input value is determined. The valid range of tone numbers is 000 to 127, so only 0 or 1 is valid for the first digit,
If any other value is entered, the input value will be ignored,
That is, step 5 is performed without performing any processing on the input value.
Return to step 4 and steps 54 and 5 until a valid value is entered.
Repeat steps 5 and 56. If 0 or 1 is entered,
The input value is set as the first digit (step 57).
In accordance with this input value, the LED display 16 (Fig. 2) displays "0-
"-" Or "1--" is displayed (step 58).

When the first digit is validly set and input, the next ten-key input is awaited (step 54). When there is a ten-key input, the second digit is determined in step 55 and step 59 is entered.
Proceed to. In step 59, the value of the first digit is determined, and if it is 0, the input value of the second digit is set as it is as an effective input value (step 61). If the first digit is 1, set the value when 0, 1 or 2 is input (step 61) and ignore when 3 to 9 are input until a valid value is input. Steps 54 and 5
Repeat steps 5, 59 and 60. When the input value is set in the second digit, the LED display will show "00-" depending on the input value.
"12-" is displayed (step 62).

When the second digit is validly set and input, the next ten-key input is awaited (step 54). When there is a ten-key input, 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, and if it is 0, the input value of the third digit is set as it is as an effective value (step 64). As a result, a three-digit effective tone color number is set, and this tone color number is sent to the tone generator circuit 8 (step 65). This tone number setting value is LED
It is displayed on the display (step 66) and the process returns to the main routine.

As a result, when a valid 3-digit value is input, the 3-digit input value is automatically set as the tone color number without the operation of the enter key which has been conventionally performed.
The tone generator circuit 8 generates a tone signal of a tone color having a tone color number set according to the keyboard operation.

On the other hand, when the value of the first digit is 1 in step 63, the routine proceeds to step 67, where the value of the second digit is discriminated.
Since the effective range of the tone color setting value is 000 to 027, 2
If the digit is 0 or 1, the input value at the third digit is set as it is as an effective value (step 64). The second 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), 8 or 9
In this case, since it is unsuitable, it is ignored and steps 54, 63, 67 and 68 are repeated until a valid value is input.

As described above, the three-digit tone color number is set. FIG. 5 is a flowchart for setting the tempo value from the parameters according to the present invention. The tempo value has three digits and takes a value from 040 to 240. As in the case of the tone color number setting described above, the performer 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 tone color setting, the ten-key input is awaited (step 69), and the input digit is determined (step 70). In the case of the first digit input (first input operation),
In step 71, if 0, 1 or 2 is input, it is directly set and displayed as an input value (step 7).
2,75). If 4 to 9 are entered in the first digit (first input value), these are values that cannot be taken as the first digit, so consider them as the second digit and set 04 to 09. Is displayed (steps 73 and 74). If the first digit (first input value) is 3, it is ignored, that is, the process returns to step 69 without performing any processing on the input value, and steps 69, 70 and 71 are repeated until an appropriate value is input.

In the case of the second digit input (second input operation), the set value of the first digit is discriminated in step 76, and the flow is divided according to that value. When the first digit is 0, the second digits 0 to 3 are ignored, and when the first digit is 4 to 9, this is set and displayed as the second digit input value (steps 78 and 79). When the first digit is 1, the input value of the second digit is set and displayed as it is (steps 78 and 79). When 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 set value is Since only 240 can be taken, 0 is set in the third digit (step 81), 240 is displayed as the tempo value (step 82), the tempo value is stored in the RAM 11 (step 83), and the process returns to the main routine. . When the first digit is 2 and the second digit is 5-9, it is ignored and a proper value is entered. Step 6
Repeat steps 9, 70, 76 and 80.

When the setting up to the second digit is completed and the third digit is to be set, the input value is set as it is as the third digit (step 84) and the 3-digit tempo set value is displayed (step 85). ), Stores the tempo value in the RAM 11 (step 83), and returns to the main routine.

As described above, the tempo value having the valid range of 040 to 240 is set. Although the tone color or tempo is selected as the parameter to be set in the above embodiment, the present invention can be applied to rhythm and other parameters. Further, in the above-mentioned embodiment, the numeric input is carried out by the ten-key pad, but if the parameter is designated by the value of the plural digits, the character may be inputted by the alphabet key or the like (for example, AB or KS for the two-digit character). . In addition, the valid range of the value of the parameter may be displayed. Further, when the input value is ignored or other digits are forcibly confirmed, the fact may be notified by visual display or voice. Although the electronic musical instrument has been described in the above embodiments, the present invention is not limited to the electronic musical instrument, but can be applied to general electronic equipment such as game equipment, audio equipment, and computer equipment including various electronic control devices.

[0029]

As described above, in the parameter setting device for electronic equipment according to the present invention, when the value of each digit of the parameter setting value of a plurality of digits is designated, this input is performed based on the input value. The number of digits that the value can take is determined and the input digit is automatically determined. Therefore, depending on the parameter value you are trying to enter, enter the number a number less than the number of digits that can represent the maximum value that the parameter can take. Therefore, the input setting process can be efficiently executed, and the operability of parameter input can be improved.
