The generator has an adder (27) for adding a signal of a normal music sound (15) and a signal of a string vibration sound of a released key. A reading of a waveform of he normal music sound is activated at a band pass filter (33) for the string vibration sound by adequate abase of a barrier frequency of the signal of the string vibration sound in reaction to a sound starting instruction. The adequate abase is increased and the signals of the respective normal music sound and string vibration sound are damped based on preset envelopes in reaction to a sound stopping instruction. |
