1. A musical tone signal synthesizing apparatus for an electronic musical instrument, comprising:

  • a manipulator for generating performance information corresponding to manipulation thereof;

    envelope signal generating means for converting the performance information into an envelope signal, a value of which changes over time;

    excitation means for generating an excitation signal on the basis of the envelope signal; and

    a loop circuit for circulating the excitation signal inputted from the excitation means, the loop circuit having delay means which delays a signal circulating in the loop by a delay time corresponding to a tone pitch of a musical tone signal to be generated,wherein the musical tone signal is extracted from at least one of the loop circuit and the excitation means.
