Fogbank by Vain Audio is a free multi-effect designed for producers who want width, motion and controlled chaos from a single insert. It can duplicate the incoming signal into as many as 16 voices, then shape those voices with modulation and a flexible effect chain.

A Cloud of Up to 16 Voices

Fogbank starts by multiplying the source into a stack of voices. Instead of behaving like a simple chorus, those voices become material for a larger modulation system. The result can range from subtle stereo thickness to unstable, animated textures that feel much larger than the original signal.

This is especially useful on pads, synth leads, vocals, guitars and one-shot effects that need movement without manually duplicating tracks.

Deep Modulation Without a Modular Patch

The plugin provides six mono modulators or LFOs, four macro controls and six polyphonic modulators. That gives you enough control to create evolving motion while keeping the workflow inside one plugin window.

Three serial effect slots let the processed voices move through additional stages, so Fogbank can act as a complete creative chain rather than only a voice multiplier.

From Subtle Width to Extreme Texture

Low voice counts and gentle modulation can add believable thickness. Push the duplication and modulation harder and the same source can become a haze of pitch, motion and spatial detail. The macros are particularly useful for automation because several aspects of the effect can be moved together during transitions.

Cross-Platform Free Release

Fogbank is available for Windows, macOS and Linux in VST3 and CLAP formats, with Audio Unit support on macOS. The current release listed by KVR is version 1.0.1.

There is no temporary giveaway clock attached to the plugin: it is presented as a free product by Vain Audio.

Where Fogbank Fits Best

Ambient, cinematic, experimental electronic music and modern pop sound design are obvious homes for Fogbank, but it can also be useful in club production. A short synth stab or percussion hit can become a wide transition layer, while a restrained setting can give a static pad more life.

Final Thoughts

Fogbank is a strong free choice when a normal chorus or doubler feels too predictable. Its 16-voice architecture and generous modulation system can create anything from controlled width to complex moving clouds without building a huge routing setup.
