Unrivaled 
Polyphonic Power

Born from our admiration for Mutable Instruments’ Plaits, Coral was created to offer something both powerful and flexible — an all-in-one 8-voice module with a wide and ever-growing range of diverse engines. With built-in effects, full multitimbral capabilities, and comprehensive MIDI integration, Coral effortlessly integrates into any Eurorack setup.

Big Sound.
Small Footprint.

Despite its compact 14HP size, Coral delivers a massive sound palette — from lush pads, strings, and dense drones to powerful monophonic leads and basses. Whether you’re building a full track or adding one expressive voice, Coral adds depth, clarity, and power to your rack.
