MOK Filtryg is a professional dual filter effect plugin combining a 12dB State Variable Filter (morphable between Lowpass/Bandpass/Notch modes with audio-rate FM capability) with selectable 24dB Ladder or Biquad Filter (Lowpass/Highpass/Bandpass/Notch), offering parallel/series/mixed routing, extensive modulation framework (envelope follower responding to sidechain dynamics, two-stage envelope function generator with manual/MIDI/threshold triggers, oscillator usable as LFO or audio-rate modulation source, MIDI keyboard tracking, tempo-synced tempo control), drive/saturation processing per filter, input/output level controls, comprehensive automation and MIDI support, 13 customizable color themes and 34 language options (including Klingon and Old Norse), and extensive factory preset library. Designed for producers, sound designers, and electronic musicians pursuing rhythmic animation and timbral expressiveness beyond static EQ, it addresses the need for creative filtering with real-time modulation enabling synthesizer-like filter control on any audio source.

Key Takeaway

MOK Filtryg is radical in philosophy: filters shouldn’t just EQ—they should animate, express, and transform. The dual architecture enables tonal blending; the modulation framework enables rhythmic expressiveness. For electronic producers wanting filter effects that inspire, it’s essential; for traditional mixing, it’s specialty tool.

The Dual Filter: Complementary Architectures

Most filter plugins offer one filter type. Filtryg offers two, operated independently or in combination.

Filter 1 is a 12dB State Variable Filter—warm, morphable, capable of audio-rate FM. Filter 2 is choice of Ladder (warm, resonant, 4-pole classic) or Biquad (modern, digital, multiple topologies).

The insight: combine warm ladder lowpass with bright biquad highpass, and you get richness plus articulation simultaneously. Parallel routing blends characters; series routing cascades for steep slopes.

Rekkerd’s 2025 review nailed it: “The filters are amazing. Top notch quality, intuitive and inspirational to work with. Once you touch it, you will start using it on every track.”

This isn’t EQ. This is tonal sculpting.

The State Variable Filter: Morphable Expression

Filter 1’s 12dB SVF is not static. It morphs between modes: Lowpass → Bandpass (modern) or Lowpass → Notch (classic).

Unlike step-wise mode switching (click a button, mode changes), morphing is continuous. Subtle turns of the Morph knob shift character progressively—from pure lowpass to bright bandpass in one smooth gesture.

This is borrowed from classic Oberheim and EMU designs. The result: tonal fluidity impossible with traditional filters.

Additionally, audio-rate FM enables the filter to be modulated at audio frequencies (not just LFO speeds), creating harmonic generation and FM synthesis effects. Filter becomes partial synthesizer.

The Ladder vs. Biquad Choice: Sonic Philosophy

Filter 2 offers two personalities:

Ladder (Classic):
4-pole lowpass/highpass with Moog-style warmth and resonance. Drive parameter adds harmonic saturation—pushing the filter adds character, not just loudness. For rich, musical tones.

Biquad (Modern):
Multiple filter types (LP/HP/BP/Notch) with precision digital character. Clean, transparent, surgical. For clinical frequency shaping.

The power: use both. Ladder for warmth, Biquad for precision. Parallel routing blends; series routing cascades.

CareersinMusic described Filtryg perfectly: “Coming at you like something out of a Sci-Fi movie you’ll be controlling your own spaceship with this plugin.”

Parallel/Series/Mixed Routing: Signal Architecture

Three routing options enable different tonal outcomes:

Series: Filter 1 output feeds into Filter 2. Cascading filters create steep slopes and complex resonances. Use for surgical subtractive tones.

Parallel: Both filters process input independently, outputs blended. Enables simultaneous warm (Ladder) + bright (Highpass Biquad) response. Use for rich, multidimensional tones.

Mixed: Hybrid approach (both feeds into output stage). Balance between cascade and blend characteristics.

Practical example: Parallel routing with Ladder lowpass (warm bottom) + Biquad highpass (presence top) = professional bass tone with top-end cut—all from one effect, no EQ needed.

The Modulation Framework: Animation Engine

Where most filters end, Filtryg begins. Three independent modulation sources enable synchronous rhythmic and timbral expression:

Envelope Follower (Dynamic Response)

Input sidechain signal (usually the audio being processed) controls filter cutoff. When audio peaks, filter opens; when audio quiets, filter closes.

Parameters: Threshold (trigger point), Attack (opening speed), Release (closing speed).

Use case: Create automatic wah-wah effect on bass following its own dynamics. Or use external sidechain: bass duck the filter cutoff of a pad underneath, creating rhythmic pumping.

This is how modern pop/electronic music achieves that “breathing” filter effect.

Envelope Function Generator (Timed Sweeps)

Two-stage envelope (Attack/Decay + Sustain/Release) triggered manually, via MIDI, or by threshold.

Use case: Load a preset with filter envelope modulating cutoff. Press a MIDI key or manual trigger button, and the filter sweeps from closed to open over the attack time, then releases. Repeatable, perfectly timed, independent of audio dynamics.

Enables synthesizer-like filter behavior on any audio source.

Oscillator (Rhythmic Motion)

LFO or audio-rate modulation source, tunable in semitones, syncable to DAW tempo.

Low frequency: Create rhythmic filter wobbles (0.5 Hz = slow pulse, 4 Hz = fast wobble).
Audio frequency: Create FM synthesis effects or harmonic distortion via filter modulation.

Envelope can shape oscillator amplitude and frequency, adding contour to modulation.

Combined Power: All three operate simultaneously on different filter parameters. Envelope Follower modulates Filter 1’s cutoff while Function Generator modulates Filter 2’s resonance while Oscillator modulates the drive. Extraordinarily expressive.

MIDI Keyboard Tracking: Playing Filters

Connect a MIDI keyboard. Filter cutoff tracks MIDI pitch—play a note, filter sweeps to match.

This transforms Filtryg from audio effect into playable instrument. Load a resonant preset, feed it a pad or drone, and play filter melodies from your keyboard.

This is synthesizer behavior applied to an effect.

The Approachable-Yet-Complex Interface

Filtryg’s interface is knob-based, organized by signal flow. Left side: input. Center: two filters. Right: output. Modulation controls below each filter.

Visually striking dark theme with cyan/orange accents mirrors the “Sci-Fi spaceship” aesthetic referenced in reviews.

The challenge: first 30 minutes feel overwhelming. CatSynth TV’s tutorial showed this—interface is “dizzying… little bit daunting at first.” But “once you understand where everything is, it becomes quite clear.”

15-minute tutorial video clarifies everything. Then it’s intuitive.

The Factory Presets: Inspiration by Example

Extensive preset library demonstrates Filtryg’s creative range. Load “Rhythmic Pumping” and hear envelope follower creating sidechain effect. Load “Ambient Sweep” and hear timed filter morphing. Load “FM Distortion” and hear audio-rate modulation creating harmonic chaos.

Presets aren’t required—they’re inspiration and education.

Quality is professional-grade.

Audio-Rate FM: The Synthesis Connection

Standard LFOs modulate at low frequencies (0.1-20 Hz). Filtryg’s oscillator can modulate at audio frequencies (20Hz+).

Result: FM synthesis effects, harmonic generation, filter becoming a creative tool beyond “remove frequencies.”

For sound designers, this is powerful. For traditional mixing, it’s specialty feature.

Languages & Themes

34 language options (including Klingon, Old Norse, Sanskrit) + 13 color themes show MOK’s commitment to accessibility and user preference.

Practical: Multiple color themes include high-contrast option for color-blind users.

This detail reveals philosophical approach: software should adapt to users, not users to software.
