PURPOSE: To increase the degree of freedom in the edition of playing data by automatically changing playing data in a specific timing range over a plurality of prescribed length sections in accordance with a playing data changing condition only by specifying the specific timing range in the prescribed length sections and the changing condition. CONSTITUTION: When specific timing is specified by a timing range specifying means 2 and a playing data changing condition is specified by a changing condition specifying means 3, a playing data changing means 4 changes playing data in each prescribed section belonging to the specified specific timing range in accordance with the specified changing condition over a plurality of prescribed length sections. Thereby only playing data stored in a playing data memory 1 and belonging to the specific timing range in respective prescribed length sections are changed, based upon a required condition over a plurality of prescribed length sections. Consequently, restriction to the edition of playing data can be removed and playing data can be efficiently edited. |
