Implementation of multi-poly function Sound Generation Method including MIDI wave and Autolooping wave and time variance wave and original wave, which use block crossfading and phase modulation of memory address in Non-memory semiconductor

摘要

way communication between electronic musical instruments've set an international standard MIDI (MIDI-Musical Instrument Digital Interface) signal sequential blocks of (Block) unit transmitting and automatic repeat interval, and the frequency is changed if the data in memory to control the tempo of the sound generating standing crossfade modulation (inverse cross modulation signal of a predetermined period), the sound generation method using a co- This way of implementing a non-semiconductor memory device is disclosed. The present invention is a method to create an address to output the cross-fade data to the changed address information and memory speed varying with time using a database that is already stored in the external transfer or receive the data transmitted is temporarily to make the desired sound and (v) a MIDI interface for analysis. Specifically, MIDI and WAV MIDI interface unit and audio information detection means, separated by a transfer means for transferring MIDI information detected by the sound generator and sound generating unit, internal memory and auto-repeat interval selector, tone generator, tone modulation means, and an output circuit. A MIDI signal input from the external MIDI interface unit using both serial and parallel communication system communication system recognizes a MIDI signal, and automatically recognize whether the internal MIDI tone generator section repeats the tone for generating the sound for the MIDI signal delivers the converted signal to select the appropriate signal is selected. The sound generating unit is the part that generates a negative signal for the coming transformation from a MIDI input sound sound sound generator part and one that can make the sound generated when the occurrence frequency and amplitude and the modulated sound by changing the tempo of speech and modulation means, and finally connects the signals generated in the sound modulation means to output digital-to-analog converter for export to the outside. Sound generating device of the present invention can generate a sound from the sound generating unit receives an input signal from the outside of the simple general MIDI, the original sound wave data is data the user can also optionally with multiple modulation / variable with the media that the mobile phones, entertainment, etc. can be applied to the sound by using electronic instruments and sound when the generator is significantly increased efficiency of the necessary equipment, the system program.
