Abstract: In the preset invention, in an initial stationary state of a drumstick section, a CPU stores each axis component of geomagnetism obtained by a magnetic sensor in a RAM, and obtains each axis component of geomagnetism obtained by the magnetic sensor which is changed by a motion provided to the drumstick section at every predetermined timing. Then, the CPU accumulates each axis component of geomagnetism obtained at every predetermined timing, for each predetermined interval, and conforms each axis component of geomagnetism accumulated thereby to each axis component of geomagnetism stored in the RAM.

Abstract: A sensor obtains an angular rate of a stick member. A sound source map includes plural areas disposed in a virtual space. CPU presumes a direction of a turning axis of the stick member based on the angular rate obtained by the sensor, while a user is operating the stick member, calculates an angular rate of a top of the stick member based on the angular rate obtained by the sensor with the angular rate in the longitudinal direction of the stick member removed, calculates a position of the holding member in the virtual space after a predetermined time, based on the recent direction of the turning axis of the stick member and recent angular rate of the top of the stick member, and sends a sound generating unit a note-on event of a musical tone assigned to an area corresponding to the calculated position among the plural areas.

Abstract: 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.
