TwoRuleFilter
Key Features
- Self-resonant Moog-type filter with highpass, lowpass, and bandpass modes for classic analog-style frequency shaping
- Scrambler feature that randomly rearranges filtered audio at selectable beat divisions for tempo-synced glitch and stutter effects
- Three modulation sources for cutoff frequency: manual control, tempo-synced LFO, and invertible envelope follower
- Built-in bit crusher with adjustable depth from 16-bit down to 1-bit for harsh digital degradation textures
- Mix knob for blending dry input with processed wet signal to dial in the right amount of effect
- Sensitivity parameter that controls how smoothly or roughly the filter cutoff frequency responds to modulation changes
Description
TwoRuleFilter by 2Rule is a self-resonant Moog-type filter effect plugin built for creating rhythmic, glitchy textures from any audio source. It offers highpass, lowpass, and bandpass filter modes with cutoff frequency control via manual adjustment, tempo-synced LFO, or an invertible envelope follower.
The standout feature is the scrambler, which divides a bar into selectable time intervals and randomly rearranges the filtered audio in a tempo-synced pattern. This turns any input signal into choppy, rhythmic, glitch-style output that stays locked to your project tempo.
A built-in bit crusher lets you degrade the signal from 16-bit all the way down to 1-bit, adding harsh digital grit on top of the filtered sound. The mix knob blends between the dry input and the processed wet signal, while a sensitivity parameter controls how smoothly or abruptly the filter cutoff frequency changes.
TwoRuleFilter is an updated version of the original 2RuleFilter, featuring a redesigned GUI and new presets. It was developed by Tugrul Akyuz under the 2Rule name and has been recognized by multiple music production outlets for its distinctive approach to combining classic analog-style filtering with modern glitch effects.
Available for Windows and macOS in VST, VST3, and AU formats, TwoRuleFilter runs in 64-bit mode.

Tips
- Use the scrambler feature to add unexpected rhythmic elements to your tracks.
- Experiment with the bit crusher to create gritty, lo-fi sounds.
- Adjust the sensitivity control to achieve smooth transitions in your filter modulation.
- Combine manual, LFO, and envelope follower controls for dynamic and evolving filter effects.
- Utilize the mix knob to blend the original and processed signals for a balanced sound.
Frequently Asked Questions
What makes TwoRuleFilter different from a standard filter plugin?
TwoRuleFilter combines a Moog-type resonant filter with a scrambler that randomly rearranges filtered audio at beat-synced time divisions. This creates rhythmic, choppy glitch effects that go well beyond typical filter sweeps or LFO modulation.
How does the scrambler feature work?
The scrambler divides one bar into different time intervals based on the selected beat division, then randomly plays the filtered audio fragments in a new order. The result is a tempo-locked, rhythmic, stutter-like effect applied to whatever signal you feed through the plugin.
Can TwoRuleFilter be used for subtle filtering or is it only for extreme glitch effects?
It handles both. With the scrambler and bit crusher disabled, TwoRuleFilter works as a straightforward Moog-style filter with LFO and envelope follower modulation. The mix knob and sensitivity control let you blend in subtle filtering alongside more aggressive processing.
Is TwoRuleFilter the same as 2RuleFilter?
TwoRuleFilter is an updated version of the original 2RuleFilter, released in 2020 with a redesigned GUI and new presets. The core filter engine and scrambler remain the same, but the interface and usability were significantly improved.
