Filter Force Free Is A Modulated Filter Plugin By TheWaveWarden


TheWaveWarden releases Filter Force (€50), a modulation plugin with a dual filter architecture. A freeware version called Filter Force Free is also available.

If the name TheWaveWarden sounds familiar, it’s because he is the developer behind Odin 2, a popular open-source virtual synthesizer. Filter Force marks the beginning of a new plugin series focusing on modulation. In the case of Filter Force, it’s all about modulating filters.

In this article, we will focus on Filter Force Free, the freeware edition which lacks some of the features found in Filter Force. Despite its limitations, the free version is a powerful and highly versatile modulation tool that is well worth your attention.

When running Filter Force Free for the first time, you’ll be greeted with a quick walkthrough tutorial (pictured below). It’s a cool move by the developer and something I’m used to seeing in mobile apps, but not audio plugins.

FilterForce greets you with a built-in tutorial. Neat!

A quick-start interactive tutorial like this is a great way to help new users get started and is definitely more fun than reading a manual. That said, you can skip the tutorial altogether if you want to prove to yourself and the rest of the world that you’re a level 100 plugin wizard.

The free edition comes with two filters: a 24 dB high-pass and a 24-dB low-pass filter. Both filters let you adjust the cutoff, resonance, gain, pan, and drive. The drive parameter distorts the signal, resulting in a more aggressive sound.

The modulation section at the bottom lets you define up to four separate free-form curves. These can be used to modulate any plugin parameter. You can draw a curve quickly using a brush tool or fine-tune it by dragging the control points.

The interface is one of the best-designed ones I’ve seen in a while. The controls are large and clear, the color scheme is perfect, and you can set the GUI to any size from the main menu.

So, what exactly are the differences between the free and paid versions of Filter Force? The full edition costs €50 and implements several upgrades, the most important of which is a massive lineup of over twenty filter types.

It also comes with four MSEGs (instead of just two in the freeware edition) and a preset browser. Presets are another handy addition, allowing you to store a collection of your favorite modulated filter curves for use in future projects.

Filter Force Free is available in 64-bit VST3 and AU plugin formats for compatible digital audio workstations on Windows and macOS.

    • Hi this is the developer! Sorry you had a bad experience.

      I assume you’re talking about a laggy user interface issue? I’ve just pushed a fix which should solve this issue in the latest version 1.0.3. Feel free to try it again. If there’s any more issues do not hesitate to contact me!

      Thanks, TWW
