DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter input device for inputting various parameters for controlling a musical tone of an electronic musical instrument.

[0002]

2. Description of the Related Art The tone signal waveform of an electronic musical instrument is determined by various parameters. By adjusting these parameters, the timbre and the like of the tone can be edited. Parameters for determining the tone signal waveform are several tens to
Because it is over 100, it is impossible to provide individual controls for all of these parameters. For this reason, an operator for inputting a parameter and a designating means for designating one of the parameters are provided, and after the parameter to be edited is designated by the designating means, the value is changed and inputted by the operator. I have.

[0003]

A variety of operators for inputting parameters have been put into practical use, but there is a data entry slider as a commonly used operator for inputting parameters. The data entry slider is constituted by a slide volume, and is an operation element indicating a static position (resistance value) of the slider at that time as a parameter. That is, the maximum value of the parameter is indicated when the slider is at the upper end, and the minimum value of the parameter is indicated when the slider is at the lower end. By the way, when a parameter to be edited is specified, if the value is immediately updated to the value specified by the operator, it is inconvenient for operation. Until the value is updated, the value is not updated. However, if the operator is operated even in one step, the value is updated to the value indicated by the operator at that time, so that the value stored in the parameter storage means greatly deviates from the value indicated by the operator. In such a case, the parameter is updated to a completely different value, and the timbre suddenly changes. Further, even if a parameter to be edited is specified, the position of the operator and its parameter value are irrelevant until the operator is operated, so that there is a drawback that the player misunderstands the parameter value.

In particular, a specific value (for example, “0”) in which the characteristic of the parameter greatly differs from that of another parameter
In such a case, the player performs an operation completely different from the intention of the player (including a case where no operation is performed), so that the player may misunderstand that the malfunction has occurred.

An object of the present invention is to provide a parameter input device for an electronic musical instrument which solves the above-mentioned problem by displaying whether or not a designated parameter is a specific value.

An electronic musical instrument according to an embodiment of the present invention will be described with reference to the drawings. An electronic musical instrument according to an embodiment of the present invention is an electronic musical instrument having an operation panel provided with various switches for editing a tone (tone signal waveform). The operation panel is provided with a plurality of parameter designation switches for designating various parameters for determining the tone,
A data entry slider 1 for updating designated parameters is provided.

FIG. 1 is a diagram showing the configuration near the data entry slider. The data entry slider 1 is constituted by a slide volume, and has a knob 2. The position of the knob 2 indicates the parameter value designated by the data entry slider.

The value range of the plurality of parameters is as follows:
Although there are various values such as 0 to 99, 0 to 7, and -50 to +50, the values indicated by the data entry slider 1 are the maximum value at the upper end and the minimum value at the lower end for all parameters. At the stage when the stored parameters are designated, the position of the data entry slider and the set value are irrelevant, and it is difficult to determine what value is currently set. Therefore, an LED 3 is provided near the data entry slider 1.

FIG. 2 is a diagram showing an initial blinking state of the LED 3, and FIG. 3 is a flowchart showing an operation of a control unit of the electronic musical instrument. In FIG. 2, an LED is indicated by a value indicated by a slider and a setting position of a designated parameter.
3 is determined. However, in this figure, L
The blinking of ED3 depends on whether the set value is 0 or not.

In FIG. 3, it is first determined whether or not a parameter designation switch (not shown) is turned on or a value of a data entry slider is changed (n1, n2). When the parameter designation switch is turned on, n1 to n
Then, the process proceeds to 3 and the value of the parameter stored in the storage area designated by the switch is read out to the buffer VOL (n3). It is determined whether or not this value is 0 (n5),
If 0, the LED 3 is turned off (n6), otherwise, L
The ED is turned on (n7). On the other hand, when the data entry slider 1 is operated and the value changes, the value indicated by the slider is set in the buffer VOL (n4).
Thereafter, the flow advances to n5.

FIG. 4 is a diagram showing another embodiment of the present invention. In this embodiment, two LEDs 4 and 5 indicating an upward direction and a downward direction are provided near the data entry slider 1 instead of one LED 3. In this case, when the set value is shifted upward from the predetermined value (0), the LED 4 is turned on, and when the set value is shifted downward, LE4 is set.
D5 is turned on. Furthermore, if the set value is 0, both of them can be turned off, and if the value of the parameter coincides with the position of the slider, both can be turned on to indicate this.

An electronic musical instrument has a pitch bend wheel 6 (FIG. 5) for raising and lowering the pitch of a musical instrument that is sounding.
The pitch bend wheel 6 can also be used to set a pitch width that can be moved up and down by using parameters. However, pitch no matter how operate the pitch bend wheel 6 If this parameter is present I Do to 0 is not up and down. An LED is provided near the pitch bend wheel 6 to notify the player of this state. When the change width of the pitch is 0, the LED 7 is turned off to notify that the pitch does not change even if the wheel is operated. The same can be done with the modulation wheel. Further, the LED may be turned on when the operation amount of the pitch bend wheel 6 and the actually output parameter do not match.

The controls are not limited to the data entry slider and the pitch bend wheel, and any controls may be used, and the control target may be any parameter. Further, the predetermined value in this embodiment is 0, but the predetermined value can be set to a value other than 0.

[0016]

As described above, according to the present invention, whether or not the parameter stored in the storage means is a predetermined specific value is displayed. And misunderstanding can be prevented.
