Abstract

본 발명은 퍼스널 컴퓨터에 전자건반을 연결하여 이 건반으로 연주되는 악보를 컴퓨터에서 데이타 변환 및 신호처리하여 악기음을 발생, 출력시켜줄수 있도록한 전자건반악기 장치와 그의 악기음 출력 제어방법에 관한 것이다.The present invention relates to an electronic keyboard musical instrument device and a method for controlling the musical sound output thereof, by connecting an electronic keyboard to a personal computer and generating and outputting musical notes by data conversion and signal processing of the sheet music played by the computer. .

종래의 전자건반악기는 건반부와 악기음 출력제어용 프로세서, 프로그램 및 음원데이타 메모리, 음원 IC, 디지탈/아날로그 변환기, 필터, 증폭기, 스피커, 기능선택(리듬, 음색, 자동반주 등등) 스위치부등을 구성요소로 하여 독립된 1개의 제품으로 구성되므로 일반 사용자가 구입하기에는 많은 비용이 들고, 회로구성이 복잡한 문제점이 있다.Conventional electronic keyboard musical instruments comprise a keyboard unit, a processor for controlling the sound output, a program and sound source data memory, a sound source IC, a digital / analog converter, a filter, an amplifier, a speaker, and a function selection switch (rhythm, tone, auto accompaniment, etc.) Since it is composed of one independent product as an element, it is expensive for a general user to purchase, and there is a complicated circuit configuration.

본 발명은 별도의 프로세서나 제반 메모리, 디지탈 신호처리 회로등의 배제되고 악보의 운지를 위한 전자거난부만을 구비하고, 이 전자건반부를 병렬케이블 또는 직렬케이블이나 키이보드 케이블을 이용하여 퍼스널 컴퓨터에 연결하며, 퍼스널 컴퓨터내에는 상기 전자건반부에서 눌려진 건반의 키이코드값을 읽어들이는 수단과, 이 키이코드값을 처리하여 악기음 데이타로 변화시킨 수단과, 악기음 데이타에 대응하는 악기음을 발생시켜 출력하는 수단을 구비하므로서 간소한 회로구성으로 저가의 전자건반악기 장치를 제공하고, 기존의 퍼스널 컴퓨터를 이용한 건반으로 실제적인 연주를 수행할 수 있으며, 퍼스널 컴퓨터로 용이하게 악기음을 발생시킬 수 있도록한 것으로, 전자건반악기에 적용한다.The present invention includes only an electronic coarse part for fingering of music scores, which is excluded from a separate processor, various memories, and digital signal processing circuits, and is connected to a personal computer using a parallel cable, a serial cable, or a keyboard cable. The personal computer generates means for reading the key code value of the key pressed by the electronic keyboard, a means for processing the key code value and converting the key code value into instrument sound data, and an instrument sound corresponding to the instrument sound data. It provides a low-cost electronic keyboard instrument device with a simple circuit configuration by providing a means for outputting, and can perform actual performance with a keyboard using a conventional personal computer, and easily generate musical instrument sounds with a personal computer. Applied to electronic keyboard instruments.
