ABSTRACT:
An electronic musical instrument includes an excitation circuit, a closed loop circuit, a characteristics analysis circuit and a control circuit. The excitation circuit generates an excitation signal in response to performance information. The closed loop circuit causes the excitation signal inputted from the excitation circuit to circulate thereabout musical tone signal. The closed loop circuit also has a delay circuit for delaying the musical tone signal for a predetermined time. The characteristics analysis circuit analyzes an input signal and generates a control signal corresponding to the result of the analysis of the input signal. The control circuit controls characteristics of the musical tone signal circulating in the closed loop circuit in response to the control signal. The musical tone signal circulating in the closed loop circuit is then outputted therefrom as a sound signal.
