Abstract

First display object associated with a control operating member and a second display object associated with a tone color effect parameter are displayed, and variation of a displayed position of the first display object is controlled in accordance with operation of the control operating member. Control value of the tone color effect parameter is determined in response to variation in relationship between the first and second display objects, and tone control is performed on the basis of the determined control value. Further, the variation of the displayed position of the first display object is controlled so as to move on and along a set path, so that displayable positions of the first display object is limited to the set path. Control value of the tone color effect parameter is determined on the basis of relationship between displayed position of the first and second display objects to perform tone control.

Claims

1. An electronic music apparatus comprising:

a control operating member;

a display device that displays at least a first display object associated with said control operating member and a second display object associated with a tone color effect parameter;

a setting section that sets a path to be used as a display course of said first display object;

a display control section that controls variation of a displayed position of said first display object, in accordance with operation of said control operating member, to move on and along the path set by said setting section;

a determination section that determines a control value of the tone color effect parameter, associated with said second display object, in accordance with relationship between respective displayed positions of said first display object moving on and along the set path and said second display object; and

a tone control section that performs tone control on the basis of the control value of the tone color effect parameter determined by said determination section,

wherein a style of control of the tone color effect parameter to be performed according to operation of said control operating member is determined in accordance with setting of the path.

2. The electronic music apparatus as claimed in claim 1, wherein said setting section sets the path by specifying start and end points of the path and associates an operating range of said control operating member with the path by assigning minimum and maximum values of an operation amount of said control operating member, associated with said first display object, to the start and end points, respectively.

3. The electronic music apparatus as claimed in claim 1, wherein said control operating member associated with said first display object is an endless operator operable continuously and capable of continuously outputting an operation value corresponding to operation thereof, and said setting section sets a path that allows said first display object to return to the start point once said first display object reaches the end point, and

wherein said display control section is adapted to perform display control such that said first display object repeatedly moves on and along the path every predetermined operation amount of the endless operating member.

4. The electronic music apparatus as claimed in claim 1, wherein said setting section sets the path of a discontinuous shape by combining a plurality of lines of a same shape or different shapes.

5. The electronic music apparatus as claimed in claim 1, wherein an effective area, representing a predetermined range over which parameter control is made effective, is set in said second display object displayed on said display device, and wherein control, by said control operating member associated with said first display object, of a tone color effect parameter associated with said second display object is made effective on condition that said first display object is located within the effective area, and said determination section determines a control value of the tone color effect parameter in accordance with relationship between respective displayed positions, within the effective area, of said first display object, whose displayed position is controlled in accordance with operation of said control operating member, and said second display object.

6. A computer-implemented method for controlling a tone in response to operation of a control operating member, said method comprising:

a step of displaying at least a first display object associated with said control operating member and a second display object associated with a tone color effect parameter;

a step of setting a path to be used as a display course of said first display object;

a step of controlling variation of a displayed position of said first display object, in accordance with operation of said control operating member, to move on and along the path set by said step of setting;

a step of determining a control value of the tone color effect parameter, associated with said second display object, in accordance with relationship between respective displayed positions of said first display object moving on and along the set path and said second display object; and

a step of performing tone control on the basis of the control value of the tone color effect parameter determined by said step of determining,

wherein a style of control of the tone color effect parameter to be performed according to operation of said control operating member is determined in accordance with setting of the path.

7. A computer-readable medium storing a program causing a computer to perform a method for controlling a tone in response to operation of a control operating member, said method comprising:

a step of displaying at least a first display object associated with said control operating member and a second display object associated with a tone color effect parameter;

a step of setting a path to be used as a display course of said first display object;

a step of controlling variation of a displayed position of said first display object, in accordance with operation of said control operating member, to move on and along the path set by said step of setting;

a step of determining a control value of the tone color effect parameter, associated with said second display object, in accordance with relationship between respective displayed positions of said first display object moving on and along the set path and said second display object; and

a step of performing tone control on the basis of the control value of the tone color effect parameter determined by said step of determining,

wherein a style of control of the tone color effect parameter to be performed according to operation of said control operating member is determined in accordance with setting of the path.
