BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument that allows parameters for various functions and effects to be changed, and particularly to one that allows immediate changes in settings.

0002

BACKGROUND OF THE INVENTION In recent years, it has become mainstream for electronic musical instruments to be equipped with display elements such as liquid crystals and to be interactive in order to make them easier to operate and use. A hierarchical structure is used to set various functions. First, select a mode for each similar function group, and then select various functions to call up the setting screen for the purpose you want to set.
Parameter settings can be changed.

[0003] A conventional electronic musical instrument will be explained below. FIG. 2 is a panel diagram and a display element diagram illustrating a conventional electronic musical instrument. In FIG. 2, 21 is a mode selection switch for each functional group, 22 is a page switch for selecting various functions, 23 is a parameter change switch, 24 is a liquid crystal display element, and 25 is a reverb on/off switch.

FIG. 3 is a hierarchical diagram below functional groups. In FIG. 3, 31a to 31f display selectors after operating the mode selection switch for each of the 21 functional groups, and 32 is a display example of a screen for setting reverb effect parameters.

Regarding the electronic musical instrument configured as described above,
The operation will be explained below. First, by operating 21 mode selection switches for each functional group, and then operating 22 page switches for selecting various functions, settings for various functions and effects can be changed.

For example, if you want to change the depth of the reverb, if there is a depth operation switch on the operation panel, you can change the depth by operating the switch, but due to space or If it is not possible to provide a depth control switch due to cost issues, the depth setting will be changed in the mode settings. In that case, first operate the 21f effect mode switch,
Various effect-related functions are set, and the page switch 22 is turned up/down to call up the depth setting screen 32. Thereafter, the depth is adjusted using the parameter change switch 23a.

[0007]

[Problems to be Solved by the Invention] However, in the conventional configuration described above, in order to change the reverb depth setting, the setting can only be changed by operating the mode switch 21 and page switch 22. The problem is that there are many switch operations required to reach the parameter setting screen, making the operations complicated and difficult to use.

A first object of the present invention is to solve the above-mentioned conventional problems, and is to provide an electronic musical instrument in which parameters for various functions and effects can be quickly changed.

A second object of the present invention is to provide an electronic musical instrument in which the settings of various functions and effects can be changed while always turning them on or off.

0010

[Means for Solving the Problems] In order to achieve this object, the electronic musical instrument of the present invention has an operator that turns on or off various functions and effects of the electronic musical instrument to be controlled, and a continuous press of the operator. means for measuring time; display requesting means for requesting activation of a display screen for setting parameters related to the control after measuring a certain time; means for displaying the requested setting screen for a certain period of time; It is equipped with a display element for displaying information and an operator for changing the settings of the displayed parameters.

[0011] Furthermore, the above functions and effects are always turned on when a display screen for setting parameters is requested to be displayed.

0012

[Operation] According to this configuration, when changing the parameter settings of various functions such as reverb, by holding down the on or off switch for that function for a certain period of time, the parameter setting screen is called up on the display element, and the parameter setting screen is called up on the display element. It is possible to provide an electronic musical instrument whose settings can be changed instantly.

[0013] By keeping the button pressed for a certain period of time, it is distinguished from a normal on/off operation, so that the display and operation are not confusing.

[0014] Furthermore, since the above functions and effects are always turned on when a display screen for setting parameters is requested to be displayed, it is possible to provide an electronic musical instrument that allows parameter changes to be confirmed audibly. .

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 is an operation panel consisting of a reverb on/off switch 11, a display element 15, a parameter change switch 16, etc., and 12 is a detection means for detecting whether the reverb switch is held down for a certain period of time. , 13 is a microcomputer, and 14 is a display screen switching means.

The operation of the electronic musical instrument constructed as described above will be explained below. First, if you hold down the control 11 that turns the reverb function on or off for a certain period of time,
The means 12 for measuring the duration of the press for a certain period of time senses it and issues a command to the microcomputer 13. The microcomputer 13 sends a request to display the reverb parameter setting screen to the display screen switching means 1.
Display element 15 for displaying the requested setting screen.
Output and display. Then, the settings are changed using the parameter change switch 16.

The requested setting screen is displayed for a certain period of time. Also, while parameters are being changed, the screen does not return to the original screen for a certain period of time.

[0019] Furthermore, since the functions and effects mentioned above are always turned on when a screen for setting parameters is requested to be displayed,
Parameter changes can be confirmed audibly.

In this embodiment, the microcomputer 13 may process the means 12 for measuring the press duration time and the display screen switching means 14 for requesting to display the reverb parameter setting screen.

[0021]

[Effects of the Invention] As described above, according to the electronic musical instrument of the present invention,
Controls for turning on or off various functions and effects of the electronic musical instrument to be controlled, means for measuring the duration of pressing the controls, and activation of a display screen for setting parameters related to the controls after measuring a certain period of time. A display requesting means for requesting the setting screen, a means for displaying the requested setting screen for a certain period of time, a display element for displaying the setting screen, and an operator for changing the settings of the displayed parameters are provided. As a result, it is possible to realize an excellent electronic musical instrument in which the settings of parameters for various functions such as reverb can be changed instantly.

[0022]Furthermore, when a display screen for setting parameters is requested to be displayed, the functions and effects are always turned on, so that changes in parameters can be confirmed audibly.
