HY-Filter4: Semi-Modular Multi-Engine Filter Effect by HY-Plugins Free Download

At its core, HY-Filter4 offers a multi-engine filter, so you can choose the filter character that suits the source. Around it sit 38 built-in effect units, which can be placed in the FX chain to process the signal further.

The modulation side is where the plugin is most distinctive. Ten types of modulator provide 42 modulation units in total, and they can be applied to the main filter, the effect units and the modulators themselves. Modulation is assigned by drag and drop, which keeps routing visual and quick to change.

CTRL SEQ is a built-in grid sequencer with 16 tracks and 12 pattern snapshots. Each track can be assigned to an effect or modulation unit, and once it is assigned, that unit is controlled by the sequencer rather than by manual movement alone.

This makes it practical for rhythmic filter sweeps, evolving effect changes and patterns that repeat in step with your project. Because each unit can be routed independently, you can build layered movement from several units at once.
