Abstract: An automatic musical playing instrument comprises a memory for storing playing data of a plurality of pieces of music, a playing order memory for storing playing order of the pieces of music stored in the memory and an order change switch which is valid during playing. The playing order can be changed by the order change switch during playing. If the playing order is changed, the music of the changed order is played after the present playing is ended. The instrument includes a mode memory for storing a mode as to whether a pause should be made after the present playing is ended, and a mode change switch which is valid during playing. If the mode change is designated during the playing, the designated mode to be changed is set when the present playing is ended.

Abstract: 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.
