PROBLEM TO BE SOLVED: To provide an arpeggiater generating a real arpeggio sound. SOLUTION: Attenuating input signals showing respective musical sounds of a composition are converted freely to lasting signals by a hold circuit 20, and the pitches of the signals outputted from the hold circuit 20 are shift-ed by a pitch shift amount decided based on the interval of the arpeggio sound shown by the frequency, the tune set by a tune setting part 33 and the pitch of the input signal detected by a pitch detection part 34 stored in a pitch shift control part 32 at the timing of prescribed once or above by a pitch shift processing part 31, and the envelope of the shifted signal is deformed by an envelope processing part 51 at the timing the same as respec-tive timing, and an attack is given. |
