Musical performance device, method for controlling musical performance device and program storage medium

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 operable on a virtual plane, a position detecting section which detects position coordinates of the musical performance component on the virtual plane, a storage section which stores layout information including positions of a plurality of areas arranged on the virtual plane and musical tones respectively associated with the plurality of areas, and a mode specifying section which specifies one of a position change mode and a musical performance mode, the program being executable by the computer to perform functions comprising:

• certain operation position detection processing for detecting a position of the musical performance component on the virtual plane when a certain operation is performed by the musical performance component;
• judgment processing for judging whether the detected position of the musical performance component is within any one of the plurality of areas arranged based on the layout information;
• sound generation instruction processing for, when the position of the musical performance component is judged to be within one area of the plurality of areas by the judgment processing in the musical performance mode, giving an instruction to emit a musical sound of a musical tone associated with the one area;
• and
• position change processing for when the position of the musical performance component is judged to be within a given area of the plurality of areas in the position change mode, changing position of the given area based on the position coordinates detected by the position detecting section, and changing the layout information stored in the storage section based on the changed position.
