Description

전자악기의 베이스음 발생 방법How to generate bass sounds for electronic instruments

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명 방법의 동작과정 설명을 위한 플로우 챠트, 제2도는 본 발명 방법에 따른 장치의 블록 구성도.1 is a flow chart for explaining the operation of the method of the present invention, Figure 2 is a block diagram of an apparatus according to the method of the present invention.

Claims (1)

각 음정마다 고유의 건반번호(K0, K1, K2, …)가 배정된 코드음 입력수단(1)을 통하여 마이크로 프로세서(2)에 입력된 건반신호를 낮은 번호로 부터 높은 번호의 오름차순으로 분류하여 기억수단(3)의 코드버퍼[B(0), B(1), B(2), …]에 순차적으로 기억시키고 이어서 B(1)-B(0)감산을 행한 값이 “1” 또는 “2” 또는 “5”인가를 판별하는 과정과, B(1)-B(0)값이 “1” 또는 “2” 또는 “5”가 아닌 경우 B(0)값을 1옥타브 올리고 이어서 오름차순으로 분류하는 단계부터 반복하여 수행하는 과정과, B(1)-B(0)값이 “1”이면 maj 코드 “2”이면 min7 코드 또는 Seventh 코드 “5”이면 maj 코드 또는 min 코드로 베이스음을 판단하여 B(0)값을 1옥타브 올리고 이어서 B(1)≥12이면 모든 코드 버퍼[B(0), B(1), B(2), …]의 값을 1옥타브 내린 다음 오름차순으로 분류하며 B(0)=베이스음으로 출력하는 과정과, B(1)<12이면 모든 코드버퍼[B(0), B(1), B(2), …]의 값을 오름차순으로 분류하며 B(0)=베이스음으로 출력하는 과정으로 이루어진 것을 특징으로 하는 전자악기의 베이스음 발생방법.Ascending order of the keyboard signals input to the microprocessor 2 through the code tone input means 1 assigned the unique key numbers K 0 , K 1 , K 2 , ... for each pitch Code buffers B (0) , B (1) , B (2) ,... ] And then subtracting B (1) -B (0) subtracting to determine whether the value is "1", "2" or "5", and the value of B (1) -B (0) If it is not “1” or “2” or “5”, repeat the step of increasing the B (0) value by one octave and then sorting it in ascending order, and the B (1) -B (0) value is “1”. ”For maj code“ 2 ”for min7 chord or Seventh code for“ 5 ”to judge bass sound by maj or min chord and increase B (0) by 1 octave, then B (1) ≥ 12 for all chord buffers [B] (0) , B (1) , B (2) ,... ] Values by 1 octave, sorted in ascending order, and output as B (0) = bass, and if B (1) <12, all chord buffers [B (0) , B (1) , B (2) ,… ] Is classified in ascending order B (0) = bass sound generating method of the electronic instrument, characterized in that consisting of the process of outputting. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
