Abstract
Abstract A device for use in an electronic musical instrument, in which a sound image is varied according to musical factors of musical tones. For example a sound image position, a number of sound images and/or a sound image shift pattern are varied according to a sounding order, a sound part, a tone color and/or effects. In this way, the sound image can be varied according to the contents of musical tones to realize play with a high spatial impression.
