600円で作るAdditive VCO（倍音加算VCO）-モジュラーシンセ自作
Arduino nanoとMozzi libraryを用いて、モジュラーシンセサイザー の倍音加算VCO（以下Additive VCO）を自作したので、その備忘録。
背景
自作モジュラーシンセの22作品目。
シンセサイザーの音声合成方法には、いくつか分類方法がある、そのうちの一つが、倍音減算式か倍音加算式の区別だ。
その使い勝手の良さから、世の中のシンセサイザーのほとんどが、倍音減算式である。しかし、モジュラーシンセは倍音加算式のVCOの比率も高い。
Mozziライブラリを用いて、様々な音声合成方式のVCOを作りたいと思い、今回はAdditive VCOに挑戦した。
設計構想は、ハモンドオルガンのドローバーを、CVで変調させるイメージがあった。スペクトルは整数倍に限定することで、音楽的（自然的）な音色を目指す。
制作物のスペック
ユーロラック規格 3U 6HPサイズ
電源：30mA ( at 5V ) / 29mA ( at12V )
5V単電源で動作可能。または12V単電源で動作可能。
knob1：fundamental frequency （基音周波数）
knob2：harmonics gain （倍音ゲイン）
knob3：harmonics spectrum （倍音周波数分布)
CV1：harmonics gain
CV2：harmonics spectrum
V/oct（10bit , 5Vp-p)
出力は4Vp-p。
基音と、7つの倍音を出力する。いずれの波形もサイン波だ。
基音はV/octで制御する。
スペクトル、つまり何倍の倍音を追加するかは"harmonics spectrum"で制御する。追加される倍音は基音の整数倍であるため、音楽的な音色になる。
基音と倍音のゲインは"harmonics gain"で制御する。
"harmonics spectrum"と”harmonics gain"は任意の値を設定することはできない。あらかじめテーブルに格納された値を参照する、ウェーブテーブルの様な形式としている。
256種類のスペクトルと、256種類のゲインの組み合わせで、無限大の音色を作ることができる。
製作費
総額600円
---------------------------------
Arduino nano 互換品200円
パネル 100円
オペアンプ 40円
etc
過去の2OSC VCO、FM VCOからオペアンプを変更している。より安価で入手しやすいMCP6232に変更した。
オペアンプは単電源のフルスイングなら、基本的に何を使っても問題ない。
プログラミング
今回もMozziライブラリを使用している。非常に使いやすい。
まず初めに、同時出力可能な音数を調査した。10以上の音を同時出力すると、ノイズが発生する。そのため、同時発音数は8にした。
音色や音楽は数学的である。そのため、プログラムも数学的な処理（例えば、二倍にする、三倍にする）をすればよい。ピタゴラスは偉大なり。
ハードウェア
2OSC VCO、FM VCOから、V/oct回路の構成を変更している。アドバイスを受けて、分圧による電圧低下が起きないよう、プルダウン抵抗を制限抵抗とジャックの間に移動した。
私もまだ未熟なので、アドバイスは非常に助かる。
音声出力回路(D9,D10)のローパスフィルタは、推奨値よりもカットオフ周波数が小さい。構成される音が正弦波のため、不要な高調波が目立ってしまう。それをカットする必要があった。
