Abstract
The purpose of the present invention is to offer an electronic musical instrument which can synthesize the sound of brass instruments with fidelity and furthermore in real time. In order to achieve the above purpose, the musical sound synthesis algorithm is to utilize the tonguing information as well as the embouchure information in addition to the sound generation information, the frequency information, and the sound volume information, which have been used as the playing informations in conventional electronic musical instruments. Furthermore, by tabulating the functional relations between the above-mentioned playing informations and corresponding output waveforms, and storing them in memories, necessary waveforms for sounding the musical instrument can be obtained by only referring to those tables, thereby the speed-up, that is, the realization by hardware, can be realized and thus the sound of brass instruments can be synthesized with fidelity and in real time.
