PURPOSE:To move repetitively a sound image generated by a sound sounded within a predetermined space along with an orbit stored in matching with the extent and shape of the space in advance such that an electronic musical instrument is played in a concert hall, for example. CONSTITUTION:For example, an electronic keyboard musical instrument is played in a concert hall, sound image moving data used to move a sound image of a played musical sound along an orbit in matching with the hall are selected from a panning ROM in a panning control circuit 108 based on the result of measuring a distance of plural sets of two points representing the extent and shape of the hall by an extend measurement device 106. Then a sound image moving means controls share of musical sound quantity sounded from an L channel speaker 110 and an R channel speaker 112 to control the localization of the sound image of both the L and R channels, and the entire musical sound volume sounded from both the speakers 110, 112 is controlled and the sound image is moved in the front/rear direction to move the sound image repetitively in the forward/backward/left/right directions along the orbit in matching with the concert hall. |
