Abstract
A parameter control device according to an embodiment includes a value acquiring unit and a parameter output unit. The value acquiring unit acquires an indicating value of a first operation element. The parameter output unit outputs a plurality of parameter values corresponding to the acquired indicating value, based on setting information and a correspondence relation between the indicating value and a coordinate in an area defined by a plurality of coordinate axes. The setting information is for setting a relation between a plurality of parameter values and a coordinate. The plurality of parameter values being for controlling a state of content.
Claims22
A parameter control device comprising:
- a display device;
- a user interface including a first operation element;
- a memory storing instructions;
- and
- a processor that implements the instructions to:
- acquire an indicating value of the first operation element;
- and
- output a plurality of parameter values corresponding to the acquired indicating value, based on setting information and a correspondence relation between the acquired indicating value and a coordinate, among a plurality of coordinates, in an area defined by a plurality of coordinate axes, the setting information being for setting a relation between the plurality of parameter values and the coordinate in the area defined by the plurality of coordinate axes, the plurality of parameter values being for controlling a state of content;
- display the area on the display device;
- specify, via the user interface, a locus, which is a line, representing a route passing through specified points in the displayed area;
- and
- set, based on the specified locus, the correspondence relation between the acquired indicating value and each of coordinates on the specified locus,
- wherein each of the plurality of coordinates is associated with a plurality of different parameters associated with sound signal generation,
- wherein the displayed area displays the specified locus and an instruction marker on the specified locus,
- wherein a value conversion table defines the correspondence relation between the acquired indicating value and each of the coordinates on the specified locus, and
- wherein the instruction marker, which indicates a coordinate corresponding to the plurality of parameter values to be output, moves on the specified locus in response to an operation of the first operation element.

A method of controlling a parameter, the method comprising:
- acquiring an indicating value of a first operation element of a user interface;
- outputting a plurality of parameter values corresponding to the acquired indicating value, based on setting information and a correspondence relation between the acquired indicating value and a coordinate, among a plurality of coordinates, in an area defined by a plurality of coordinate axes, the setting information being for setting a relation between the plurality of parameter values and the coordinate in the area defined by the plurality of coordinate axes, the plurality of parameter values being for controlling a state of content;
- defining, using a value conversion table, the correspondence relation between the acquired indicating value and the coordinate in the area;
- displaying the area on the display device;
- specifying, via the user interface, a locus, which is a line, representing a route passing through specified points in the displayed area;
- setting, based on the specified locus, the correspondence relation between the acquired indicating value and each of coordinates on the specified locus;
- and
- displaying the specified locus in the displayed area and an instruction marker on the specified locus,
- wherein each of the plurality of coordinates is associated with a plurality of different parameters associated with sound signal generation,
- wherein the value conversion table defines the correspondence relation between the acquired indicating value and each of the coordinates on the specified locus, and
- wherein the instruction marker, which indicating a coordinate corresponding to the plurality of parameter values to be output, moves on the specified locus in response to an operation of the first operating element.
