Gatekeeper by Polyverse Music and Infected Mushroom is a powerful volume modulation plugin designed to add dynamic movement and rhythmic interest to your audio. It offers a wide range of effects including sequenced volume patterns, MIDI gates, stutter effects, ducking, and creative gain clipping. Whether you're aiming for sharp volume spikes or smooth sidechain effects, Gatekeeper provides the tools to sculpt your sound with precision and impact.

Equipped with a unique variable smoothing algorithm, Gatekeeper enables sample-accurate volume envelopes that deliver punchy gating and sequencing while maintaining smooth output transitions. Its boost and clip functions allow for the distortion of transients, adding character and snap to your sounds. This plugin excels in applying fast volume changes that can transform the energy of any track, making it suitable for both creative sound design and mixing tasks.

Gatekeeper's flexibility extends beyond simple volume control, functioning as an LFO, envelope, step sequencer, and sample-accurate automation tool. Users can easily draw automation curves using intuitive brushes and shortcuts, while its eight envelopes can be triggered via MIDI or generate CV output for external hardware integration. With hundreds of included patterns and presets, Gatekeeper is compatible with major DAWs in VST, AU, and AAX formats on Windows and Mac systems, offering a comprehensive solution for dynamic modulation and creative expression.
