USB MIDI FM synthesizer that supports voice synthesis using CSM (Composite Sinusoidal Model
モジュール構造のハードウェアとなっている。 コントローラモジュールには4本のDockがあり、FM音源モジュールを接続する。YM2203とYM2608が混在可能。 FM音源モジュールのアナログ出力は、ミキサー・アンプモジュールを接続する。 コントロールパネルモジュールはFM音源モジュールのI/Oポートに接続する。
システムコントローラーはRaspberryPi Pico2を使用しているが、パフォーマンスは若干落ちるがPicoも使用可能。
- /CS生成用3bit - /RD, /WR - A0, A1 - D0 - D8 - /IRQ (4bit)
FM音源LSIは5V系なので、Raspberry Pi Picoとの接続にはAE-LLCNV8-DIP20などで3.3V/5Vレベル変換が必要である。
アナログ回路の低ノイズ化を考慮して、秋月電子の超ローノイズ可変電圧キットAE-TPS7A4700を5V出力で使用している。 消費電流は800mA程度を見込む必要があり、入出力電圧差は1V程度としなければならない。 6V/1.8AのAD-A60P180を推奨ACアダプタとする。
