PURPOSE:To cope with an actual noise generating mechanism by providing a noise generating means for generating a noise signal having a predetermined spectrum distribution according to an exciting signal and a noise overlapping means interposed in a predetermined position in a loop circuit to overlap its own input signal and the noise signal. CONSTITUTION:In a musical sound synthesizing circuit 9 is given noise data N of turbulence as offset according to data (f) corresponding to flow rate of air flow passing through a gap between a mouthpiece and reed to perform a signal process adapted to a noise generating mechanism in an actual wind instrument. A musical sound signal outputted through such signal process is supplied to a sound system 40 which processes a speaker SP to sound the musical sound. Thus, in actual wind instrument blowing, noise effects of sub-tones, panting sounds or the like magnifying noises can be reproduced, so that the musical sounds adapted to an actual noise generating mechanism are composed to reproduce the noises generated in performance with high fidelity. |
