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.

Inside Coral’s
Advanced Design

8 Full Voices, Mono or Poly

Eight independent voices, played mono or poly. Up to 8 oscillators per voice, 64 in total.

27 Sound Engines

Pick the engine per voice: Moog-style analog, FM, virtual analog, wavetable, drum modeling and sample playback. Up to 10 engines loaded at a time, chosen by you in the Firmware Updater.

Built-in Reverb, Chorus and Delay

Every voice has its own send to the onboard reverb, chorus and delay. You can place each part in space without leaving the module.

Multi-Part Capability

Split the 8 voices into parts. Each part gets its own filter, amp, envelope, FX send, pan and more, so one module plays a full multitimbral patch.

MPE Support

Coral is MPE-compatible, so an MPE controller gives you per-note expression across all 8 voices.

Complete Midi Integration

Every parameter responds to MIDI CC, from FX sends to sample selection. Coral pairs with the OXI One or any polyphonic sequencer.
