PURPOSE:To obtain the musical sound waveform signal generating device which can generate a musical sound waveform signal by accurately simulating a natural musical sound, specially, a wind instrument, and provides the more real and natural continuation of a sound. CONSTITUTION:Control parts 5-8 input pitch information and supply a 1st para meter and a 2nd parameter respectively to a linear part 2 which has a circulation path where a waveform signal is circulated and a nonlinear part 1 which generates an excitation signal. The nonlinear part 1 generates and outputs the excitation signal to be impressed to the linear part 2 according to the 2nd parameter which is inputted. The linear part 2, on the other hand, circulates the waveform signal according to the 1st parameter which is inputted. A final output is led out of the linear part 2. A control circuit compares a last selected pitch with a current selected pitch and does not input the 1st parameter to the linear part 2 when there is no variation. |
