PROBLEM TO BE SOLVED: To more easily perform a sound region setting of automatic accompaniment of a base sound and a code sound. SOLUTION: This device is provided with a code information detecting means 4 detecting a code type and a code route from a key information, a position detecting means 5 detecting a position to which an operation key generating the key information corresponds out of each position divided into each prescribed key region, and a code conversion means 6 reading out the position and rotation data of the code type from a rotation data storing means 3 in accordance with detected results of the code information detecting means 4 and the position detecting means 5 and performing code conversion for a reference accompaniment pattern. By setting a sound region of automatic accompaniment in accordance with a detected result of position information using the code conversion means 6, a sound region of automatic accompaniment also can be automatically changed by only changing a key region pressed for detecting code information. |
