VERMONA twinVCFilter 雙通道電壓控制多模式濾波器（Dual Multimode Filter）
一款 雙通道（Dual）電壓控制濾波器模組，每一個濾波器區段都能獨立運作，並可在 Lowpass、Highpass（12 dB/oct） 與 Bandpass（6 dB/oct） 模式之間切換。這樣的設計不僅適合傳統減法合成，也能靈活應用於節奏處理、立體聲音像塑形與複雜調變結構。
在訊號路由方面，twinVCFilter 提供 Serial（串聯）、Dual（雙獨立）、Parallel（並聯） 三種路由模式。使用者可以將單一訊號依序通過兩個濾波器，或是同時送入兩個濾波器進行平行處理，也可以讓兩個濾波器完全獨立，彷彿系統中存在兩顆獨立濾波模組。透過這些路由方式，可以輕鬆建立不同斜率的 Bandpass、Notch Filter，甚至將濾波斜率倍增，形成更陡峭的頻率切除效果。
在 Dual 模式 下，twinVCFilter 還提供相當實用的 Link 功能，可將兩個濾波器的 Cutoff 與 Resonance 進行連動，非常適合用於立體聲訊號處理，讓左右聲道在保持一致性的同時，仍能維持高解析度與穩定的聲音表現。
此外，模組內建的 Mix Section 進一步擴展了訊號塑形的可能性。使用者可以手動或透過 CV 訊號，在兩個濾波器輸出之間進行 Crossfade。這讓低通與高通之間的無縫轉換、不同濾波斜率之間的平滑移動，甚至是兩組完全不同訊號的動態混合，都變得相當直覺。搭配方波或矩形波 LFO，還能實現節奏式切換與調變效果。
在共振（Resonance）設計上，VERMONA 特別著重於「音樂性」與「穩定度」。twinVCFilter 的共振反應可從細緻、頻率依賴的強調，一路推進至穩定的 Self-Oscillation。在自激狀態下，濾波器可產生純淨且紮實的 Sine Wave，非常適合作為打擊音色或低頻音源的基礎。透過交叉調變（Cross Modulation），twinVCFilter 甚至能在系統中扮演聲音產生器的角色，當系統中缺乏 LFO 時，也能臨時作為 Vibrato 或調變來源使用。
