What Complexx does
The plugin is built around a soft-knee bus compressor that binds tracks together while retaining crisp transients, and its attack and release controls can be adjusted to shape how the signal responds. A mix knob at the top bar sets parallel processing, so the compressed and dry signal can be blended in one control. The developer lists versatility comparable to its hardware counterpart, with features that cover individual tracks as well as the mix bus.
Complexx also includes an integrated expander for cleaning up vocals and reducing ambient noise between phrases, and a separate instrument-oriented path meant to keep dynamics detail while adding depth and density to instruments. The developer refers to the plugin as drawing on the golden era of audio history.
Key features
- Soft-knee bus compression. The bus compressor uses a soft knee, which the developer states binds tracks together while preserving transients, suited to glueing a mix bus.
- Attack and release shaping. Attack and release controls set how quickly the compressor reacts and recovers, useful for slamming room mics or refining the punch of a drum bus.
- Mix knob for parallel processing. A mix knob on the top bar blends the processed signal with the dry signal, allowing parallel compression from a single control.
- Integrated vocal expander. An expander is built in to reduce ambient noise around vocals, working alongside the compression stage.
- Instrument polish mode. A dedicated path is intended to maintain dynamics detail on instruments while adding depth, density and clarity to individual notes.
Compatibility
Complexx is offered as VST3, AU and AAX for Windows 7 and macOS 10.7 or later in 64-bit builds, with 4 GB of RAM listed and native Apple Silicon support.
