fourMulator 是 Vermona 為 Eurorack 模組系統打造的高階 四通道數位 LFO(Low Frequency Oscillator)調變引擎。它不僅僅是一組可循環的低頻振盪器,更是一個能同時處理連續調變、節奏結構與觸發事件的核心模組。
在模組合成系統中,調變(Modulation)往往是讓聲音從靜態變得有生命力的關鍵。fourMulator 正是為了回應這個需求而設計:四個 LFO 可獨立運作,也能彼此同步,從單純的慢速參數擺動,到精密、可預期又能變化的節奏性調變結構,都能輕鬆建立。
每一個 LFO 都提供六種波形選擇,包括上升鋸齒波、下降鋸齒波、方波、三角波、正弦波,以及隨機曲線(Sample & Hold)。頻率範圍從極慢的 0.05 Hz(單一週期長達 20 秒),到高達約 100 Hz,不僅能作為傳統調變來源,甚至可進入音訊速率,用於振盪器、濾波器或 VCA 的聲音變形與音色扭曲。
fourMulator 的另一大核心在於 同步與相位控制能力。多個 LFO 可同步至同一個主時脈(Clock),在相同頻率下運作,但彼此之間的相位可進行偏移,最大可達 180°。這讓使用者能輕易建立「反向旋轉」或交錯運動的調變關係。若再透過 CV 輸入進行相位調變,則能形成更複雜、多層次的調變結構,非常適合用於演化式聲景(evolving soundscape)或節奏模組控制。
在同步模式下,LFO 可依據外部或內建時脈進行固定但可調整的 Clock Division,且分頻比例本身也可透過 CV 進行調變,進一步提升系統的動態彈性。更進階的是,fourMulator 允許同步模式的「串接使用」:其中一個 LFO 可同步外部時脈,同時成為右側 LFO 的主時脈來源,形成階層式的調變架構。
此外,fourMulator 內建 時脈產生器(Clock Generator),可透過 TAP 按鍵手動敲擊設定速度,或接受外部 Clock 訊號同步整個系統。每個 LFO 也都具備獨立的 Trigger 輸出,於每次波形重新啟動時送出觸發訊號,使 fourMulator 同時具備調變來源與節奏/事件產生器的角色。
