ABSTRACT:
The musical tone synthesizing apparatus simulating the wind instrument synthesizes a musical tone signal to thereby generate a musical tone corresponding to the wind instrument tone. Herein, the musical tone synthesizing apparatus contains one or more stages each including a bi-directional transmission circuit and a junction. In each stage, the progressive wave signal is delayed by the predetermined delay time and transmitted to the junction. The junction multiplies the signal by first coefficient, whereby the result of multiplication is transmitted to the next stage. The junction also multiplies the progressive wave signal by second coefficient, whereby the result of multiplication is fed back to the prior stage. The first and second coefficients are changed over according to an operation of a tone hole to be provided in the wind instrument. Thus, the musical tone of the wind instrument can be simulated with simple circuit or software.
