固定滤波器组的目的是增强合成器的主信号，在特定频率上添加谐波，或在其他频率上去除谐波。有些人想要创造前所未有的全新音景，将自己和听众带入全新的音乐体验世界。另一些人则希望创造更传统、更熟悉的音色，同时突破界限，利用传统“不插电”乐器所不具备的全新电压控制、功能和特性。还有一些人则两者兼顾。

于是，全新设计的 P915 MEDUSA 固定滤波器组应运而生。该滤波器可以为信号添加微妙或明显的共振，或完全去除某些频段。当与未经处理的“干”信号混合时，这种处理方式可以模拟传统乐器的实际特性。它本身也可以作为一种独特而富有创意的声音塑造方式，这是其他滤波器结构所无法实现的。

当时，市面上出现了几款基于主动滤波器设计结构的 915 硬件克隆产品。 915 的原始结构采用简单的电感器、电容器和电阻器作为滤波单元，这种结构能够产生微妙的交互作用，而这些交互作用在如今冷冰冰的半导体世界中却消失殆尽。然而，基于原始结构的设计方案却令人期待。我们找到了合适的电感器供应商，仔细研究了电路图，剔除了复制过程中产生的错误，设计了电路板，最终得到了与 Moog 在其原始用户手册中发布的原始响应高度精确且忠实的复刻版本。

有了可靠的硬件版本，软件模型的开发便可着手进行。对硬件进行细致的特性分析和测量，并结合保留 Moog FFB 独特两级设计的软件模型，最终得到了一个与原始模型高度匹配且忠实遵循的软件模型。此外，我们还添加了一些额外的功能，例如能够将每个单元的输出定向到左声道或右声道，这些功能为滤波器增添了更多可能性，使其更具魅力、实用性和独特个性。

P915 的设计、实现和质量控制均与 Analogue Realities 的 David Ingebretsen 合作完成。简而言之，P915 MEDUSA 是对 Inductor 915 固定滤波器组的精心打造，并在功能、易用性和性能方面进行了全面提升。

功能特性：
•包含十四个复古风格的固定频率电感滤波器。
•包含一个低通滤波器和一个高通搁架滤波器。
•十二个带通滤波器以半倍频程间隔设置，频率范围从 125 Hz 到 5.8 kHz。
可选择将信号分成两个六频段滤波器组（175Hz、350Hz、700Hz、1.4kHz、2.8kHz 和 5.6kHz，外加一个低通滤波器）用于左声道，以及另外六个频段（125Hz、250Hz、500Hz、1kHz、2kHz 和 4kHz，外加一个高通滤波器）用于右声道。这种分割方式非常悦耳，因为它可以作为两个独立的固定滤波器组使用，滤波器之间以八度音程间隔，并且右声道相对于左声道偏移半个八度音程。
•干湿信号交叉推子可在处理后的信号和干信号或外部信号之间进行混合，同样支持手动和电压控制的声像定位。
•零延迟
• macOS：支持 AU 和 VST3 格式。

更新日志：

版本 2.0.2，2026 年 2 月 7 日。
P915 Medusa v2 对原设计进行了改进，包括优化电路、修正曲线和简化工作流程。由于这些改进，v2 的音质可能与早期版本略有不同，但现有会话仍可正常打开。现有用户可免费升级。

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.

Features
• Features fourteen vintage style fixed frequency, inductor based filters.
• There is a LP and a HP shelf filter
• Twelve Band Pass filters are set at half octave interval spacings, which range from 125 Hz through to 5.8kHz.
• Option to split into two six band filters (175Hz, 350Hz, 700Hz, 1.4kHz, 2.8Khz and 5.6 kHz plus Low Pass) for the Left Channel, and the alternate six bands (125 Hz, 250 Hz, 500 Hz, 1kHz, 2 kHz, 4kHz plus High Pass) for the Right channel. This is a very musical split, as it can perform as two separate Fixed Filter Banks with Octave spacing between filters, and the Right channel is offset against the Left channel by a half octave.
• Wet-Dry cross fader mixes between the treated signal and the dry or external signal , again with manual and Voltage Controlled panning between banks.
• Zero latency
• macOS: AU and VST3 formats.

Changelog:

Version 2.0.2 Feb. 7, 2026
P915 Medusa v2 refines the original design with improved circuitry, corrected curves, and a clarified workflow. Because of these refinements, v2 may not sound identical to earlier versions, but existing sessions will open normally. This is a free upgrade for existing users.
