HY-Filter4 free
Key Features
- Runs the included SVF and 3BP filter engines for broad tonal shaping and resonant movement.
- Assigns modulation by dragging a modulation source to the main filter rather than relying on a fixed routing layout.
- Includes LFO, 2DLFO, random, envelope-follower, and XY-control modulation sources.
- Uses envelope following to let the filter respond dynamically to the level of incoming audio.
- Makes repeating sweeps and evolving motion possible from the included LFO-based modulators.
- Provides a resizable interface for fitting detailed control into different DAW layouts.
- Avoids the fade, preset-save, and project-state restrictions listed for the paid-version demo.
Description
HY-Filter4 free is a semi-modular audio-effect filter for turning a static track into a moving, rhythmic, or more animated sound. The free edition keeps two filter engines—SVF and 3BP—and lets you route modulation to the main filter through drag-and-drop assignments.
Five modulation tools cover the practical ways a filter needs to react in a mix: conventional and two-dimensional LFO movement, random variation, envelope following, and XY control. That makes it useful for tempo-shaped sweeps, auto-wah-style response to an incoming part, unstable electronic textures, and hands-on automation without building a long chain of separate effects.
This is the streamlined edition of HY-Filter4, rather than a timed demo: HY-Plugins says it has none of the demo limitations applied to the paid version. The official product page supplies the same free-edition flow for Windows, macOS, and Linux, while independent user comments describe it as flexible enough for auto-filter work and creative filtering once its modulation layout becomes familiar.
Frequently Asked Questions
Is HY-Filter4 free a demo?
No. HY-Plugins describes the free edition as a cut-down version of the full product without the demo limitations. The demo restrictions listed on the official page—periodic fades, no preset saving, and no stored project parameter states—do not apply to the free edition.
Which filter and modulation tools are included?
The free edition includes the SVF and 3BP filter engines, plus LFO, 2DLFO, RND, envelope follower, and XY Control modulation types. These sources can be assigned to the main filter with drag and drop.
Can it work as an auto filter?
Yes. Its envelope follower can drive the filter from the incoming signal, which is the basis of auto-filter-style response. LFO and random modulators offer more repeatable or less predictable movement when you do not want level-driven behavior.
Which systems and plugin formats are officially supported?
HY-Plugins lists VST2 and VST3 for Windows, macOS, and Linux, with AU also available on macOS. The official requirements list Windows 7 or later, macOS 10.12 or later with Universal Binary 2 and native Apple M1 support, and Ubuntu 18.04 or later.
