Doepfer A-188-9 高速 VCO 與音訊振盪器模組:Karplus-Strong 合成的核心驅動源

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。

Purchase FAQ

Q1. How is shipping calculated? Is there free shipping?

Orders over NT$3,000 qualify for free shipping. Orders under NT$3,000 incur a NT$120 shipping fee. In-store pickup is always free.


Q2. What payment methods are available?

We accept: credit card (single payment, or 3/6-month installments), bank transfer, convenience store payment code, cash on delivery, in-store payment, and AFTEE deferred payment. Installments are currently available only for credit cards issued by CTBC Bank, E.SUN Bank, and Taishin Bank. Cash on delivery is not available for software products or orders over NT$10,000.

E-invoices are issued for all purchases and sent automatically to your registered email. Once a personal (duplicate) invoice is issued, it cannot be changed or reissued as a company (triplicate) invoice.


Q3. How does in-store pickup work?

Select "In-store pickup" (free) at checkout. We will notify you by email once your items are ready. Please bring your order information to the store.

Store address: 2F., No. 2-1, Aly. 2, Ln. 244, Sec. 3, Roosevelt Rd., Zhongzheng Dist., Taipei City. Opening hours: Monday to Saturday 11:00 – 18:30 (closed on Sundays).
