Summary: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.
