ABSTRACT:
An automatic playing device including a memory which stores sequence data consisting of musical sound data and sequence data to control read-out of the musical sound data. A processing unit repeatedly reads out musical sound data specified by the control data included in the sequence data stored in this memory. A movement instruction switch gives instructions for movement of an accompaniment part to be played. A control device which, when an instruction for movement of a part to be played is issued by the movement instruction switch, terminates the operation to repeatedly read out musical sound data if musical sound data stored in the memory is being repeatedly read out by the processing unit. In which case, the control device moves system operation to an operation to read out the next sequence data. For example, automatic accompaniment is made by sequentially reading out sequence data stored in the memory, and for instance, accompaniment to improvisation is realized by repeatedly reading out a portion specified by the control data stored in the memory. Thus, if the player wishes to go out of the improvisation part and gives an instruction for movement of an accompaniment part to be played with the movement instruction switch, system operation goes to an operation to read out the next sequence data.
