PROBLEM TO BE SOLVED: To prevent sound from becoming monotone and dissonance when creating harmonized sound by converting a pitch of an inputted sound signal. SOLUTION: A sound signal (direct sound signal) inputted from a microphone 1 is converted in pitch by a pitch converter LSI 5, and the pitch-converted sound signal (converted sound signal) and the direct sound signal are mixed by a mixer 6 and outputted. The pitch converter LSI 5 converts the pitch of said sound signal to a pitch decided based on the performance information to be inputted from the performance information read from a storage device and an external device. Thus, it becomes possible to automatically pitch-convert sound into consonance based on an automatic performance, and pitch-convert to various instruments. |
