Abstract
In a musical sound synthesizing apparatus, a loop part including at least a delay element is configured to receive an excitation signal in response to a sound generation instruction so as to synthesize a musical sound signal by looping the excitation signal therein. A waveform memory stores first waveform data representing sound which is generated by a natural musical instrument and which contains resonance, the first waveform data containing a plurality of frequency components having various levels. A waveform processing unit removes, from the first waveform data, one or more frequency component having a level that does not reach a predetermined level, to generate second waveform data. The second waveform data generated by the waveform processing unit is input as the excitation signal to the loop part.
