01Overview

Sonsig Rev-A is built around a classic algorithmic reverb engine with added modern filter and modulation controls. Relab Development positions it as a fast, straightforward reverb for producers who want a usable space without menu diving. Its main controls are predelay, size, decay, width and diffusion, all accessible directly on the interface. The plugin covers a wide tonal range, from small rooms and lush halls to more realistic ambiences, and it is offered in VST3, VST2, AU and AAX formats for Windows and macOS.

Sound Character and Reverb Sizes

Rev-A includes 10 distinct reverb sizes, each with an adjustable decay time, so you can set the virtual space you need. Relab Development describes the range as running from warm, vintage-leaning reverbs to clear, modern spaces.

The Output Render Modes change the overall character of the reverb. The developer names three models, one with a low-fi vintage quality, one with a recognizable textured character, and one with a cleaner modern sound. Switching between them is a quick way to move the same space from dusty to pristine.

The Freeze function holds the reverb tail indefinitely, which is useful for drones and abstract spatial effects.

Workflow and In-Reverb Ensemble Chorus

The controls for tempo-lockable predelay, size, decay, width and diffusion are menu-free, which keeps tweaking fast. Relab Development says the plugin is designed so you can sculpt a sound in seconds.

Sonsig Rev-A also adds modulation inside the reverb itself through an ensemble chorus. According to the developer, three simultaneous modulation algorithms animate the reverb tail, which keeps long decay settings sounding lush rather than static.

The plugin is 64-bit only. It requires macOS 10.15 or later (native on M1) or Windows 10 or later, with 2GB of RAM.
