Abstract

본 발명은 전자악기의 음처리부를 통해 PCMDMAEPDLXK를 읽을 때 순차적으로 증가하는 어드레스를 역어드레스로 변환시켜 순차적으로 감소시켜 다양한 음을 발생시키는데 적당한 전자악기의 역음발생장치에 관한 것으로, PCM음데이타를 정방향으로만 읽어 음을 발생시키기 때문에 바람소리등 다양한 효과음을 내기 위해서는 음을 샘플링하여 PCM음데이타 저장부(2)에저장하여야 하므로 저장량이 많이 필요한 문제점을 해결하기 위한 것이다.The present invention relates to a reverse tone generator of an electronic musical instrument suitable for generating various sounds by converting sequentially increasing addresses into reverse addresses when reading the PCMDMAEPDLXK through the sound processor of the electronic musical instrument. In order to solve the problem that a large amount of storage is required because the sound is generated only because the sound must be sampled and stored in the PCM sound data storage unit 2 in order to generate sound effects.

본 발명은 이와같은 종래 문제점을 해결하기 위하여 음처리부와 PCM음데이타 저장부 사이에 역음발생부를 구비하여 음처리부가 PCM음데이타 저장부의 PCM음데이타를 읽을 때, 상기 음처리부에서 출력되는 악기음이 저장된 어드레스를 순차적으로 증가하는 것을 순차적으로 감소하는 역어드레스로 변환시켜 출력시키므로서 한정된 음데이타를 이용해 다양한 효과음을 발생시킬 수 있게 하고 이를통래 PCM음데이타 저장부의 저장량을 감소시킬 수 있도록 한 것으로 전자악기에 적용한다.The present invention has a reverse sound generator between the sound processing unit and the PCM sound data storage unit to solve the conventional problems, when the sound processing unit reads the PCM sound data of the PCM sound data storage unit, the instrument sound output from the sound processing unit It is possible to generate various effect sounds by using limited sound data by converting sequentially increasing stored addresses into sequentially decreasing inverse addresses, and to reduce the amount of storage of PCM sound data storage.
