PROBLEM TO BE SOLVED: To provide an automatic code attaching device having wide code advancement generation space and capable of synthesizing code advancement having required adaptation to applied melody. SOLUTION: An initial group for code advancement is applied at first (B1). Adaptation to an applied melody is calculated as an evaluation value for each code advancement of a rhythm group to be processed (B2). Genetic operation B4 (selection, mating, mutation, etc.), for the code advancement group is executed and code advancement is controlled so that a code advancement evaluation value (melody adaptive value) is increased as a whole in accordance with the advancement of generations of the code advancement group. |
