Korg - FISA Suprema C Digital Accordion (Button Key)

The Korg FISA Suprema C Digital Accordion (Button Key) distils the power of the original Suprema into a lighter, more compact instrument that is purpose-built for modern accordionists. With 92 velocity-sensitive buttons on the right hand, 120 on the left, and Korg’s advanced T2L sound engine under the hood, it delivers world-class accordion realism, huge orchestral and organ sound libraries, and deep editing in a format that is comfortable to wear for extended performances.

Designed for players who want portability without compromise, the FISA Suprema C combines Natural Bellows Response and Advanced Proportional Bellows Behaviour technologies to recreate the feel and nuance of a fine acoustic accordion, while offering the tuning stability, connectivity and flexibility of a cutting-edge digital instrument. From silent headphone practice to full-stage performances with MIDI, USB and Bluetooth integration, it is a powerful, expressive tool for traditional and contemporary styles alike.

Compact, Comfortable and Performance Ready

At just 9.6 kg in the button version, the FISA Suprema C is significantly lighter and more compact than many traditional accordions, making it easier to handle on long gigs, rehearsals and travel. The streamlined 92-button right-hand layout and optimised on-board speakers keep the instrument balanced and comfortable, while still providing a full, expressive playing surface. With up to around 9 hours of battery-powered autonomy and the ability to charge while playing, you can perform confidently without worrying about power access.

Deeply Authentic Accordion Experience

The heart of the FISA Suprema C is its ability to feel and respond like a premium acoustic instrument. Korg’s Natural Bellows Response and Advanced Proportional Bellows Behaviour continuously track bellows movement, pressure, number of keys pressed and pitch to shape dynamics in real time. Add in 45 accordion types from around the world, detailed musette detuning, cassotto simulation, growl and mechanical noises, and you get a playing experience that captures the subtlety, “air” and character of a traditional accordion, with the consistency and reliability of digital technology.

Immersive Sound Design and Customisation

Beyond its core accordion voices, the FISA Suprema C offers a vast palette of orchestral, organ, solo and synth sounds that can be freely assigned to treble, bass, chord and free-bass registers. You can customise reed combinations, cassotto placement, tuning, bass layout and even “age” the sound to taste. Hyper-Real Sound Cluster and Hyper-Real Drum Sounds Cluster technologies provide band-like accompaniments and detailed drum kits, while extensive effects and user scenes let you build and recall complex setups instantly for any style or ensemble.

Modern Connectivity and Simple Control

Despite its depth, the FISA Suprema C is designed to be intuitive. A full-colour 2.4-inch display and clear menus make navigation straightforward, with “Easy” and “Advanced” modes to suit different workflows. Extensive connectivity, including MIDI, Bluetooth MIDI, Bluetooth Audio, USB MIDI/Audio and dedicated audio outputs, allows seamless integration with computers, recording systems, live rigs and mobile devices. Whether you are practising with headphones, streaming backing tracks via Bluetooth or using it as a powerful MIDI controller, the FISA Suprema C slots effortlessly into any modern setup.

• Compact Button Layout with Natural Feel - The 92-button right-hand keyboard and 120-button left-hand section are all velocity-sensitive, giving you precise control over dynamics and articulation. The reduced size and 9.6 kg weight make the instrument easier to manage on stage or in transit, while still providing a full, expressive playing surface for serious performance.
• Advanced Bellows and Accordion Modelling - Natural Bellows Response and Advanced Proportional Bellows Behaviour technologies track bellows pressure, direction and key activity to recreate the nuanced response of an acoustic accordion. Combined with detailed algorithms for musette detuning, cassotto, growl, mechanical noises and ageing, the FISA Suprema C delivers a deeply realistic, highly expressive playing experience.
• Huge Sound Library with Hyper-Real Clusters - With 45 accordion types, multiple organ models, over 170 orchestral and synth patches, plus dedicated Hyper-Real Sound Cluster and Hyper-Real Drum Sounds Cluster sounds, you can cover everything from traditional folk and classical to pop, jazz and contemporary styles. Flexible register assignment and powerful effects let you craft layered, ensemble-like textures from a single instrument.
• Modern Connectivity and Long Battery Life - MIDI, Bluetooth MIDI, Bluetooth Audio, USB MIDI/Audio and separate audio outputs make it easy to connect to computers, interfaces, PA systems and mobile devices. The rechargeable lithium-ion battery provides extended playing time and can be charged while performing, so you can rehearse, record and gig with confidence and minimal setup.
