Doepfer A-188-9 是一款 Eurorack 格式的 VCO 模組,本質為「高速 VCO」(High Speed VCO),同時兼具高品質類比音訊 VCO 功能。
Doepfer A-188-9 是一款特殊「高速 VCO」(High Speed VCO),其開發初衷是為了提供一個超高頻率的時脈源,用以精確驅動 BBD(Bucket Brigade Device)延遲模組,例如同系列的 A-188-1 或 A-188-2。在音訊處理與物理建模(Physical Modeling)領域中,這款模組是實現高品質 Karplus-Strong 合成技術的關鍵組件。它能夠在 15kHz 至 500kHz 的極高頻率範圍內精確追蹤 1V/oct 電壓標準,確保在極短延遲時間下依然能維持穩定的音高表現。
除了作為高速時脈源,A-188-9 本質上也是一個高品質的類比音訊 VCO。它內部由一個精密音訊 VCO 與一個 PLL(鎖相迴路)倍頻單元組成,PLL 會將音訊 VCO 的頻率乘以 32 倍以產生高速輸出。這意謂著當您將其切換至標準音訊模式時,它具備完整的鋸齒波(Sawtooth)、三角波(Triangle)以及具備脈衝寬度調變(PWM)功能的矩形波(Rectangle)輸出。這種雙重特性使得 A-188-9 不僅能驅動 BBD,還能與數位雜訊(Digital Noise)、取樣機、頻率除法器或其他具備高速輸入介面的數位模組協同運作。
