特徴
- FM音源シンセサイザ
- YAMAHAのOPN系FM音源(YM2203/YM2608)を使用
- (ほぼ)GM準拠 USB MIDI音源
- CSMモードによる複合正弦波音声合成をサポート
YM2203(OPN), YM2806(OPNA)はモジュール基板となっており、コントローラーモジュールに最大4台まで混在接続が可能。システムコントローラにはRaspberryPi Picoを使用している。YM2608モジュールを4台を接続した場合、24マルチティンバー・24ポリフォニック+リズム6音の発音が可能なMIDI音源となる。
CSM音声合成のデモ
- YouTubeビデオ
YMOのソリッドステートサヴァイヴァーに収録されているテクノポリスの坂本龍一の音声を、複合正弦波音声分析で特徴量抽出し、YM2608のCSMモードで音声合成させている。

Questions
How big is the ControlPanel PCB?
It measures 100 × 75 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ControlPanel use?
115 parts, built around the 2SA1015 and 2SC1815. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ControlPanel KiCad files?
From the 46nori/FMSynthEnsemble repository on GitHub, at the commit this page was made from: the board is hardware/ControlPanel/ControlPanel.kicad_pcb and its schematic hardware/ControlPanel/ControlPanel.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ControlPanel design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
