Claims (1)

전자악기의 조옮김 방식에 있어서, 건반키 입력 유무를 체크하는 건반키 스켄과정과, 건반키 입력이 있을시 트랜스포져 키를 스캔하여 트랜스포져 키선택상태가 고유 주파수인지 분석하는 조옮김 체크과정과, 상기 조옮김 체크결과 고유 주파수 선택 상태일시 입력된 건반키 고유 주파수로 메모리 음색 파형을 리드라웃 하도록 고유의 리드아웃 주파수신호를 발생하는 정상 재생 제어과정과, 상기 조옮김 체크결과 고유 주파수 선택상태가 아닐시 입력된 건반키 고유 주파수에 트랜스포져 키 선택상태에 해당하는 값만큼 주파수를 증감하여 메모리로 변경된 리드아웃 주파수를 발생하여 조옮김된 음색을 재생토록 제어하는 조옮김 재생 제어 과정으로 이루어짐을 특징으로하는 방식.In a transposition method of an electronic instrument, a key key scan process for checking the presence or absence of a key key input, a transposition check process for analyzing whether a transposer key selection state is a natural frequency by scanning a transposer key when there is a key key input, and The normal regeneration control process of generating a unique readout frequency signal to readout the memory tone waveform at the key key eigen frequency inputted when the natural frequency is selected when the natural frequency is selected, and when the natural frequency is not selected as the natural frequency selected. A transposition playback control process for controlling the playback of a transposed tone by generating a readout frequency changed into a memory by increasing or decreasing the frequency by a value corresponding to a transposer key selection state to a key key natural frequency. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
