v2 Coming Soon


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 P914 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 914 were being introduced primarily based on active filter design structures. The original structure of the 914 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 P914 design, implementation and quality control was in collaboration with David Ingebretsen of Analogue Realities The P914 MEDUSA is simply put, a meticulous, spot-on implementation of the Inductor 914 Fixed Filter Bank but taken to the next level in functionality, usability and performance.



  • 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, AAX and VST3 formats.
  • Windows: VST3 and AAX formats.

  1. I am lucky enough to have access to the original Moog Model 10 reissue that has a very similar P907 Filterbank. What can I say. P914 Medusa is like the real deal, but with all modern goodies (plus it’s stereo!).
    Can’t recommend P914 enough.

  2. Incredible Filter sounds. I tried several other filter banks and they just don’t compete with this one in terms of sound. and great sound is something i never regret.

  3. I absolutely love this plugin,
    it sounds great …real…highly recommended

  4. P914 FFB builds on the classic Moog Fixed Filter Bank and pushes beyond its limitations to provide familiar classic filtered tones as well as some new creative ones.

    In addition to the inductor based filters, P914 adds a few features that allow for greater usability including a Mix control, preset Morphing (allows for moving filters), and my personal favorite, the Stereo filters and delay offsets per side.

    Having the latter two allow for spacial spreads (without using modulation effects like chorus). My favorite use for P914 is on acoustic guitars. Dial down the unwanted resonances, boost the sparkle and body, then separate it into a wide, lush sound. Offset the delay time in one channel to go even wider.

    Of course it works well on synths as the original was intended. You can dial in acoustic resonances for electric instruments quite well as a sound design tool. Does fun and creative work on drums as well.

    I think that it might not be seen as exciting of an effect these days, but I’ve found it to be a useful part of my collection. Also note that Pulsar Modular regularly update and bring new features to their existing plugins.

  5. What a great and beautifully sounding filterset!
    Note that in the current version v1.5.3, the plugin does not remember the plugin window size if it is changed – after closing the plugin, it always opens in the same default size (at least with the 64 bit VST3 version on Win10), which is a bit annoying. Also, the GUI design appears to be a lot less streamlined/polished compared to the newer Pulsar Modular plugins. Fortunately, there seems to be an update in the works with a GUI upgrade (and additional features as well). This is a great thing with Pulsar Modular actually – even older releases don’t get abandoned but are still improved and maintained, and updates are usually free.
