産業上の利用分野
本発明は電子楽器の記憶演奏のための入力装置に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an input device for memorized performance of an electronic musical instrument.
従来例の構成とその問題点
従来音楽を電子的に記憶させるために鍵盤とか計算機の
キーボードスイッチを用いて手足によ逆入力していたが
、楽器がやっと読める程度の素人には非常に困難であっ
た。Conventional configurations and their problems Traditionally, in order to store music electronically, people used keyboards or computer keyboard switches to input data in reverse using their hands and feet, but this was extremely difficult for amateurs who could barely read musical instruments. there were.
発明の目的
本発明の目的はメロディを知っている人なら誰でも記憶
演奏せしめるだめの入力が簡単にできる入力装置を提供
するものである。OBJECTS OF THE INVENTION An object of the present invention is to provide an input device that allows anyone who knows the melody to easily input information to memorize and play the melody.
発明の構成
本発明装置は、鍵盤等を操作する代りにメロディヲマイ
クロフォンの前で口ずさむだけで、正確に音程修正され
て記憶せしめうるよう、修正演算装置を具備しておシ、
手動入力装置に頼らない記憶演奏機の入力装置である。Structure of the Invention The device of the present invention is equipped with a correction calculation device so that the pitch can be accurately corrected and memorized simply by humming a melody in front of a microphone instead of operating a keyboard or the like.
This is an input device for a memory performance machine that does not rely on a manual input device.
実施例の説明

が簡単である。DESCRIPTION OF THE EMBODIMENT FIG. 1 shows an embodiment of the present invention. 1 is a microphone, and hum the melody you want to memorize into this microphone 1. In this case, it is easier to post-process by humming slowly, dividing the scale one by one, and with as few harmonics as possible, for example, in a woo voice, so that the intervals are clear.
２はフィルタ、３はリミッタであシ、この出力は変換器
４に導がれて夫々の音階に対応した符号に変換される。2 is a filter, 3 is a limiter, and the output thereof is led to a converter 4 where it is converted into a code corresponding to each musical scale.
変換方法としては、（１）周波数の２進計数、（２）周
波数を電圧に変換し、その電圧を符号化する、（３）周
波数を電圧に変換した後、再びその電圧を周波数に変換

ように構成されている。Conversion methods include (1) binary counting of frequencies, (2) converting frequency to voltage and encoding that voltage, and (3) converting frequency to voltage and then converting the voltage to frequency again. Then, the fluctuation of the second frequency is reduced and the frequency is counted in binary. 1] is a read-only memory (hereinafter referred to as R) for reading the absolute scale from the scale code derived from the converter 4.
The comparator 10 converts the code of the converter 4 into an absolute scale code and outputs it. Therefore, even if the output frequency of the microphone 1 deviates somewhat from the absolute scale, it is rounded off by the comparator 10 and becomes the absolute tone. In the present invention, before inputting this scale into the memory 30, the tone generator 20 is driven and the output sound is output from the speaker 21, assuming that the scale is off and rounded off in the opposite direction than intended. If you can confirm by listening and there is no problem with the confirmation result, press the memory switch 40.
By pressing , the scale is stored in memory device #30.
第２の実施例では絶対音階対応のＲＯＭ １１を用いる
代りに、絶対音階発生器１２の出力を音階切換器１３で
切換操作し、比較器１０の両入力がほぼ一致した時点で
停止せしめる如く構成されている。In the second embodiment, instead of using the ROM 11 that supports absolute scales, the output of the absolute scale generator 12 is switched by a scale switch 13, and the comparator 10 is configured to stop when both inputs almost match. has been done.
発明の効果
本発明によれば、楽器が読めない、または鍵盤等の操作
がむずかしいという人でもメロディさえ知っておれば、
それを口ずさむだけで入力でき、記憶演奏できる効果が
ある。Effects of the Invention According to the present invention, even people who cannot read musical instruments or find it difficult to operate keyboards, etc., can play musical instruments as long as they know the melody.
You can input it just by humming it, which has the effect of memorizing and playing it.
