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 operated by an instrument player, a position detecting section which detects position of the musical performance component on a virtual plane where the musical performance component is operated, and 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, the program being executable by the computer to perform functions comprising:

• predetermined operation judgment processing for judging whether a predetermined operation is performed on the musical performance component;
• change processing for similarly changing the respective positions of the plurality of areas in the layout information stored in the storage section based on the position of the musical performance component at time of the predetermined operation, when the predetermined operation is judged to be performed;
• judgment processing for judging whether the position of the musical performance component is within any one of the plurality of areas arranged based on the layout information, when a certain music-playing operation is performed by the musical performance component;
• and
• 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 giving an instruction to emit a musical sound of musical tone associated with the one area.
