ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tone control parameter setting device applied to an apparatus that generates a tone signal, such as an electronic musical instrument, for setting a tone control parameter that controls a mode of generating the tone signal.
2. Description of the Background Art
From the past, a tone control parameter setting device is known which is provided with a rectangular displayer capable of displaying characters and numerals, a plurality of function operators arranged in one row along one side of the displayer, and a parameter setting operator for setting a tone control parameter that controls a mode of generating a tone signal, on an operation panel of an electronic musical instrument. In this device, first, when any one of the plurality of function operators is operated, one function designated by the operated function operator among a plurality of functions belonging to a first hierarchy is designated. Next, when any one of the aforesaid plurality of function operators is operated again, one subfunction designated by the operated function operator among a plurality of subfunctions belonging to the aforesaid designated one function and belonging to a second hierarchy is designated.
By designation of this subfunction, the displayer displays a setting screen which corresponds to the designated subfunction and which is used for setting the tone control parameter that is designated by the subfunction and controls the mode of generating the tone signal. When the parameter setting operator is operated in this state, the tone control parameter designated by the setting screen displayed on the displayer is set in accordance with the operated parameter setting operator.
However, in the above-described conventional device, the designation of the functions in the first hierarchy and the designation of the subfunctions in the second hierarchy are carried out using the same function operators, making it difficult to grasp the hierarchies at the time of operating the function operators. Further, an operator to return from the second hierarchy to the first hierarchy needs to be provided, and also an operation to return from the second hierarchy to the first hierarchy needs to be carried out. For these reasons, designation of a desired hierarchy, function, and subfunction cannot be easily carried out, and there are cases in which the desired tone control parameter cannot be easily set to be a desired value or cannot be easily changed.
SUMMARY OF THE INVENTION
The present invention has been made in order to solve the aforementioned problems of the prior art, and an object thereof is to provide a tone control parameter setting device in which a desired tone control parameter can be easily set to be a desired value or can be easily changed.
In order to achieve the aforesaid object, a characteristic constructional feature of the present invention lies in that a tone control parameter setting device includes a displayer capable of displaying characters and numerals; a plurality of first function operators arranged in one row near the displayer for respectively designating a different function; a plurality of second function operators arranged in one row in parallel with the first function operators for respectively designating a different subfunction belonging to each of the functions designated by each of the first function operators; a parameter setting operator for setting a tone control parameter that controls a mode of generating a tone signal; a display controller for allowing the displayer to display a setting screen which corresponds to a subfunction designated by the second function operators among a plurality of subfunctions belonging to the function designated by the first function operators, wherein the setting screen is used for setting the tone control parameter that is designated by the subfunction to control the mode of generating the tone signal; and a parameter setting circuit for setting the tone control parameter, which is designated by the setting screen displayed on the displayer, in accordance with an operation of the parameter setting operator.
In this case, the display controller allows the displayer to display, for example, the tone control parameter, the functions that are allotted to the plurality of first function operators, and the subfunctions that are allotted to the plurality of second function operators, on the setting screen for setting the tone control parameter. The functions and subfunctions are displayed in the setting screen at positions corresponding to the plurality of first and second function operators respectively.
In the present invention constructed as described above, when any one of the plurality of fist function operators is operated, one function corresponding to the operated first function operator among the plurality of functions, in other words, one function among the plurality of functions belonging to the first hierarchy, is designated. Next, when any one of the plurality of second function operators is operated, one subfunction corresponding to the operated second function operator among the plurality of subfunctions belonging to the designated function of the first hierarchy, in other words, one subfunction among the plurality of subfunctions belonging to the second hierarchy, is designated. The display controller then allows the displayer to display a setting screen which corresponds to the designated subfunction and which is used for setting the tone control parameter for controlling the mode of generating the tone signal, and the parameter setting circuit sets the tone control parameter designated by the setting screen displayed on the displayer in accordance with the operation of the parameter setting operator.
As a result of this, according to the present invention, the functions belonging to the first hierarchy and the subfunctions belonging to the second hierarchy are respectively designated by the operation of the first function operators and the second function operators that are independently arranged, thereby eliminating the need for grasping the hierarchy at the time of operating the function operators as in the above-described prior art. In other words, when the first function operators are operated, the functions belonging to the first hierarchy are designated, while when the second function operators are operated, the subfunctions belonging to the second hierarchy are designated. As a result of this, the present invention eliminates the need for an operation to move from one hierarchy to another hierarchy, whereby the designation of a desired function and subfunction can be easily carried out, and a desired tone control parameter can be easily set to have a desired value or can be easily changed. Further, in the case where the displayer has a rectangular shape with longitudinal and lateral lengths that are different from each other (many of the currently easily available liquid crystal displayers have longitudinal and lateral lengths that are different from each other), numerous first and second function operators can be advantageously arranged if the first and second function operators are arranged along the longer side among the longitudinal and lateral sides.
Another characteristic constructional feature of the present invention lies in that the display controller is constructed to include a variable storing memory for storing a first variable representing anyone function among the plurality of functions designated by the plurality of first function operators and a plurality of second variables respectively representing any one subfunction among the plurality of subfunctions designated by the plurality of second function operators for each function designated by the first variable; a first renewing circuit for renewing the first variable when any one of the plurality of first function operators is operated, to a value representing the function designated by the first function operator that is operated; and a second renewing circuit for renewing
