Korg - FISA Suprema C Digital Accordion (Piano Key)

The Korg FISA Suprema C Digital Accordion takes the world-beating technology of the original Suprema and distils it into a lighter, more compact piano-key instrument. With 37 velocity-sensitive keys, 120 bass buttons and Korg’s advanced T2L engine under the hood, it delivers the sound and feel of multiple premium accordions plus orchestral, organ and synth voices in one portable, stage-ready package.

Designed for players who demand authenticity without the weight, the Suprema C combines Natural Bellows Response and Advanced Proportional Bellows Behaviour for an uncannily acoustic playing experience. Add in a powerful onboard speaker system, deep editing, extensive connectivity and long battery life, and you have a digital accordion that feels completely at home in the practice room, studio or on stage.

Compact, Comfortable and Ready to Travel

The FISA Suprema C takes the full Suprema concept and refines it into a more manageable format. The piano version weighs just 9.9 kg, with a reduced 37-key right-hand keyboard and a streamlined set of physical register switches for easier handling and longer, more comfortable performances. Despite the smaller footprint, you still get 120 velocity-sensitive bass buttons with both Standard and Free Bass modes, making this a serious professional instrument that is far easier to live with on the road.

Immersive Accordion Realism

At the heart of the Suprema C is a deep accordion engine with 45 accordion types covering instruments from around the world. You can customise reed combinations, choose cassotto placement, set growl and mechanical noises, adjust tuning and even virtually “age” the sound to taste. Detailed simulation algorithms let you fine-tune musette detuning, bellows expression, valve and key noises, resonance and more, so the instrument responds and breathes like your ideal acoustic accordion, without the need to own multiple physical boxes.

Natural Bellows Feel and Expressive Power

Korg’s Natural Bellows Response and Advanced Proportional Bellows Behaviour technologies continuously track bellows movement and pressure, adjusting the sound in real time. Independent resistance between push and pull, adaptive expression interpolation and seamless release on orchestral sounds make fast shakes, delicate swells and powerful accents feel natural and intuitive. The result is a dynamic range and responsiveness that closely mirrors a fine acoustic instrument, while giving you the consistency and control of digital.

Beyond Accordion: Full Korg Sound Engine

Leveraging technology from Korg’s flagship workstations and synthesisers, the Suprema C goes far beyond traditional accordion sounds. You have access to multiple organ models (including tonewheel, transistor and pipe types), a large library of orchestral and synth patches, Hyper-Real Sound Cluster accompaniments and Hyper-Real Drum Sounds. These can be layered or assigned across treble, bass, chord and free-bass sections, opening up everything from authentic folk and musette to cinematic textures, pop arrangements and modern electronic styles.

Modern Connectivity and Digital Convenience

The Suprema C is built for contemporary performance and production. With MIDI, Bluetooth MIDI, Bluetooth Audio, USB MIDI, USB Audio and dedicated audio outputs, it integrates easily with computers, recording rigs, live PA systems and mobile devices. Bluetooth Audio lets you stream backing tracks straight through the onboard speakers, while headphone connectivity enables quiet, high-fidelity practice. As a digital instrument it requires no tuning, offers multiple temperaments and provides stable, repeatable performance every time you switch on.
