There are provided a tone generator system using computer software and a storage medium storing the computer software. A musical tone synthesis module generates a musical tone signal by generating an excitation signal in response to an request for generating the excitation signal and at least delaying and looping the generated excitation signal. A first monitoring module monitors whether or not the request for generating the excitation signal is issued. A second monitoring module monitors whether or not the musical tone signal is generated by the musical tone synthesis module. An interruption module interrupts execution of the musical tone synthesis module when the first monitoring module detects that the request for generating the excitation signal is not issued, and at the same time the second monitoring module detects that the musical tone signal is not generated.
