Realistic Reverbs

VAST delivers a wide variety of options for real acoustic spaces and devices. From the most intimate ambient Rooms, to the grandest of Halls, or the expansiveness of immense spaces, the reverbs in this VST offer versatile sonic personality and character for a wide array of production needs.

Rhythmic Patterns

VAST sets itself apart from traditional delay tools with a diverse host of rhythmic convolutions and echoes. These tempo-synced impulse responses transform an ordinary source into a distinctly inspiring rhythmic groove. Quickly build and shape a beat from any simple sound source.

Custom Signal Flow

Not just about static impulse responses; this is a designer's playground, allowing you to define your own signal chain of the FX modules with flexible routing and additional in-depth controls. Re-arrange the Gate, EQ, Delay, Convolution, Compressor, and Mix for your desired effect.

Endless Impulses

Elevate your sonic signature by seamlessly loading your own audio files into VAST as your impulse response source. Open up endless possibilities with this VST as you shape your unique reverbs, ensuring your sound is truly one-of-a-kind.

Auto Resonance

Quickly clean up and fine-tune your effects to enhance overall sound quality and eliminate unwanted resonances caused by room acoustics and impulses. This feature intelligently scans the impulse and lowers the offending frequencies.
