Abstract

본 발명은 재생시간의 제약을 받지 아니하고, 외부환경의 상태, 혹은 상태의 변화에 대응하는 청취자의 요구에 맞는 음을 발생시켜서 유효한 음향효과를 얻을 수 있는 음향구성장치의 제공을 목적으로 한다.
그 구성을 보면, 입력신호 변환회로부(10)로 부터의 출력신호를 데이터 추출회로부(12)에 공급하고 신호를 해석하고 데이터를 추출하여 MIDI 신호 변환회로부(13)에 공급한다.
MIDI 신호변환회로부(13)는 이 데이터 추출회로부(12)에 추출한 음원데이터에 의거하여 음원제어데이터를 음원발생회로부(14)에 출력한다. 음원발생회로부(14)는 MIDI 신호변환회로부(13)로부터 제어데이터에 따른 음신호를 발음회로부(15)에 출력한다. 최종적으로 발음회로부(15)는 공급되는 출력신호를 변환하여 발음시키는 구성으로 되어있다.
