| Abstract: | In order to simplify the generating process of MIDI musical sound,the framework and its essential technologies of a mutil-channel MIDI musical sound synthesizer are described based on DFM method.This synthesizer takes use of an internal memory for musical sound and an internal register. It has two modes for generating musical sound,one is 9 kinds of melody,another is 6 kinds of melody and 5 kinds of rhythm. And it can simultaneously output different musical sound in two modes. The simulation results of ever... |
