Abstract

An object of the present invention is to provide a musical performance device by which layout information, such as information regarding the arrangement of a virtual musical instrument set, can be quickly and easily changed during musical performance and whereby the variety of musical performance can be increased. In the present invention, a CPU identifies a musical tone associated with a virtual pad in an area where the position coordinates of a marker section are located in an image captured by a camera unit section at a shot timing by a drumstick section, and emits the identified musical tone. When the position coordinates of the marker section in an image captured at a shot timing are within the area of a control pad on a virtual plane, the CPU switches processing target set layout information to other set layout information among a plurality of set layout information.

Claims

1. A musical performance device comprising:

a musical performance component which is operated by a player;

a position detecting section which detects position of the musical performance component on a virtual plane where the musical performance component is operated;

a selecting section which selects layout information from among plural types of layout information including a plurality of areas arranged on the virtual plane and musical tones respectively associated with the plurality of areas;

a judging section which judges whether the position of the musical performance component is within one of the plurality of areas arranged based on the selected layout information, when a certain music-playing operation is performed by the musical performance component; and

a sound generation instructing section which, when the judging section judges that the position of the musical performance component is within one area of the plurality of areas, gives an instruction to emit musical sound of a musical tone associated with the one area,

wherein the plural types of layout information respectively include information regarding a certain area other than the plurality of areas, and

wherein the selecting section selects layout information other than the currently-selected layout information from among the plural types of layout information, when the certain music-playing operation is performed by the musical performance component and the position of the musical performance component is within the certain area.

2. The musical performance device according to claim 1, wherein the musical performance component comprises a roll angle detecting section which detects a roll angle of the musical performance component, and

wherein the selecting section determines other layout information to be selected from among the plural types of layout information, based on the roll angle detected by the roll angle detecting section when the certain music-playing operation is performed by the musical performance component.

3. The musical performance device according to claim 2, wherein the plural types of layout information are each provided with a different layout number;

and

wherein the selecting section changes the layout number by incrementing the layout number by a predetermined number when the detected roll angle is within a first predetermined range, and decrementing the layout number by a predetermined number when the detected roll angle is within a second predetermined range, and selects layout information provided with the changed layout number as the other layout information.

4. A non-transitory computer-readable storage medium having stored thereon a program that is executable by a computer used as a musical performance device including a musical performance component which is operated by a player and a position detecting section which detects position of the musical performance component on a virtual plane where the musical performance component is operated, in which plural types of layout information including a plurality of areas arranged on the virtual plane and musical tones respectively associated with the plurality of areas are respectively including information regarding a certain area other than the plurality of areas, the program being executable by the computer to perform functions comprising:

processing for selecting layout information other than currently-selected layout information from among the plural types of layout information, when a certain music-playing operation is performed by the musical performance component and the position of the musical performance component is within the certain area;

processing for judging whether the position of the musical performance component is within one of the plurality of areas arranged based on the selected layout information, when the certain music-playing operation is performed by the musical performance component; and

processing for, when the position of the musical performance component is judged to be within one area of the plurality of areas, giving an instruction to emit musical sound of a musical tone associated with the one area.

5. A method for controlling a musical performance device including a musical performance component which is operated by a player and a position detecting section which detects position of the musical performance component on a virtual plane where the musical performance component is operated, in which plural types of layout information including a plurality of areas arranged on the virtual plane and musical tones respectively associated with the plurality of areas are respectively including information regarding a certain area other than the plurality of areas, comprising;

selecting layout information other than currently-selected layout information from among the plural types of layout information, when a certain music-playing operation is performed by the musical performance component and the position of the musical performance component is within the certain area;

judging whether the position of the musical performance component is within one of the plurality of areas arranged based on the selected layout information, when the certain music-playing operation is performed by the musical performance component; and

giving an instruction to, when the position of the musical performance component is judged to be within one area of the plurality of areas, emit musical sound of a musical tone associated with the one area.
