Musical instrument, method of controlling musical instrument, and program recording medium

摘要

A CPU (31) of a musical instrument (1) calculates distances between central positions of a plurality of virtual pads (81) and a position of a marker unit (15), by making adjustment such that a distance is shorter as a size associated with the virtual pad (81) is larger. The CPU 31 identifies a virtual pad (81) corresponding to the shortest distance among the distances calculated, as a virtual pad (81) for outputting sound. The CPU (31) identifies a tone corresponding to the virtual pad (81) for outputting sound by referring to set layout information.

主权项

1. A musical instrument, comprising:
a musical performance member that is operated by a performer; an operation detection unit that detects a predetermined operation performed by the musical performance member; an image capturing unit that captures an image including the musical performance member; a position detection unit that detects a position of the musical performance member on a plane of the image captured; a storage unit that stores layout information including a representing position and a size of a virtual musical instrument, for each of a plurality of virtual musical instruments provided on the plane of the image captured; a distance calculation unit that calculates distances between a position detected by the position detection unit and respective representing positions of the virtual musical instruments, based on corresponding sizes of the virtual musical instruments, when the operation detection unit detects the predetermined operation; a musical instrument identification unit that identifies a virtual musical instrument corresponding to the shortest distance among the distances calculated by the distance calculation unit; and a sound generation instruction unit that instructs generation of musical sound corresponding to the virtual musical instrument identified by the musical instrument identification unit.
