8-voice polyphonic Eurorack synthesizer

Polyphony is available via both MIDI and CV, with MPE compatibility for advanced expressive control. Voices can be distributed to separate parts, turning the module into a true multi-timbral modular workstation.

Includes Virtual Analog, Waveshaping, FM, Wavetable, MDO (Multiple Detuned Oscillators), String, Acid, 3VCO, Additive, as well as dedicated drum engines (Kick, Snare, Hi-Hat) and a powerful WAV Player. This variety allows you to range from acid basslines to atmospheric pads to complete grooves generated directly from the rack.

Built-in effects and total modulation

Every parameter, including effect sends, can be modulated via CV or MIDI CC. Coral integrates Reverb, Delay, Chorus and Noise, plus internal filter with dedicated amp and filter envelopes. Harmonics, Timbre and Morph controls allow immediate and musical sound modeling.

Modular Groovebox with WAV Player

The internal player supports up to 320 WAV samples (16-, 24- and 32-bit), turning Coral into a self-contained groovebox capable of producing complete tracks within the Eurorack system.

Continuous customization and updates

With the OXI Wave app, custom wavetables can be created. The module supports downloadable alternative engines and benefits from constant community-driven firmware updates, ensuring continuous evolution over time.
