Electronic musical instrument having pan control function

An electronic musical instrument having a pan control function includes a pan device for deciding a synthesizing rate of the plural wave form elements in each of the musical tone output terminals independently. Static pan control fixes an image position of a musical tone, and dynamic pan control changes the image position with lapse of time. The dynamic pan control also includes EG pan control which changes the image position on a pre-stored orbit and bias pan control which changes the image position based on specified data during playing. In addition to an operator, such as a jog dial and a modulation wheel, key touch data or key number data can be used for the bias pan control. This musical instrument can synthesize a musical tone signal by combining the pan control functions to each wave form element, thereby forming very widened musical tones.
