固定滤波器组（Fixed Filter Bank）的初衷，在于增强合成器的核心信号，即在特定频率上增添谐波，或在另一些频率上将其去除。有人渴望借此创造出前所未闻的全新声景，推动自己与听众一同踏入崭新的音乐体验世界；也有人希望在突破传统界限、充分利用传统原声乐器所不具备的电压控制、新功能与独特特质的同时，打造出更具传统感与熟悉度的音色；更有人希望能兼得二者之长。
于是，全新重构的 P915 MEDUSA 固定滤波器组应运而生。这是一款能为信号增添或细微、或显著共振，亦或是彻底剔除特定频段的滤波器。当将这一处理过程与未经处理的“干”信号混合时，便能模拟出传统乐器的真实发声特性；它也可独立运作，成为独一无二且充满创意的音色塑形源头，带来其他滤波器结构无法实现的可能性。
市面上曾推出过数款 915 的硬件复刻版，主要基于有源滤波器设计架构。而 915 的原始结构，采用电感、电容和电阻构建滤波单元，其带来的微妙交互作用，在半导体的冰冷世界里荡然无存。然而，基于原始架构进行设计，始终是值得追求的目标。我们寻得了电感元件的供应源，仔细推敲电路图，剔除了复制过程中的误差，精心设计了电路板，最终打造出与 Moog 原版用户手册中发布的特性响应高度一致、极为精准的复刻版本。
在手握可靠的硬件版本后，软件建模工作随之展开。我们对硬件进行了细致的特性分析与测量，同时在软件模型中保留了 Moog 固定滤波器组独特的两级设计架构，最终打造出与原版特性精准匹配、高度还原的软件模型。此外，我们还增添了额外功能，例如可将每个单元的输出信号单独路由至左声道或右声道，这进一步拓展了滤波器的可能性，为其增添了魅力、实用性与独特个性。
P915 的设计、实现与品控，均与 Analogue Realities 的 David Ingebretsen 紧密合作完成。简而言之，P915 MEDUSA 是对 Inductor 915 固定滤波器组细致入微、精准无误的复刻，更是在功能性、易用性与性能表现上实现了全面跃升。

The intent of the Fixed Filter Bank was to enhance the primary signal of the synthesizer, adding harmonics at specific frequencies or removing them at others. Some wanted completely new and never before heard sonic landscapes to push themselves and their audiences into new worlds of musical experience. Others wanted to create more traditional and familiar sounds, while still pushing the boundaries and making use of the new voltage controls, features, and character not available in a traditional “un-plugged” instrument. Some wanted both.
Enter the new reimagined P915 MEDUSA Fixed Filter Bank. A filter which adds subtle or not so subtle resonances to the signal or removing frequency bands altogether. This process, when mixed in with the unaltered, “dry” signal, can mimic the actual behavior of a traditional instrument. It can also act on its own as a unique and creative source of sound shaping possibilities not available in other filter structures.
Several hardware clones of the 915 were being introduced primarily based on active filter design structures. The original structure of the 915 used simple inductors, capacitors, and resistors for the filter cells, which delivered a subtle interactions were lost in the sterile world of semiconductors. However, a design based on The original structure was begging to be pursued. A source for inductors was found, the schematics were scrutinized, errors in the schematics from copying were weeded out, circuit boards were designed, and the result was an extremely accurate and faithful copy of the original response as published by Moog in their original owner’s manual.
With a solid hardware version in hand, a software model could begin. Careful characterization and measurement of the hardware, along with a software model keeping the unique structure of the Moog FFB with its two stage design, has resulted in a software model that faithfully matches and follows that of the original. Adding some extra features, such as being able to direct the output of each cell to either the left or right channel, opens up additional possibilities that add to the charm, utility, and character of the filter.
The P915 design, implementation and quality control was in collaboration with David Ingebretsen of Analogue Realities The P915 MEDUSA is simply put, a meticulous, spot-on implementation of the Inductor 915 Fixed Filter Bank but taken to the next level in functionality, usability and performance.
