Korg - FISA Suprema Digital Accordion (Button Key)

Korg’s FISA Suprema Digital Accordion (Button Key) is a next-generation instrument that fuses traditional Italian accordion craftsmanship with Korg’s most advanced digital technology. Offering the feel and nuance of a 120-bass acoustic accordion alongside a vast palette of global accordion sounds, orchestral voices and organs, it gives serious players a single, lightweight instrument that can handle everything from folk and musette to jazz, classical and contemporary pop.

With 92 right-hand buttons, 120 left-hand bass buttons, Natural Bellows Response and Advanced Proportional Bellows Behaviour, the FISA Suprema responds just like a fine acoustic accordion, capturing every subtle swell, shake and dynamic shift. At the same time, powerful internal sound engines, deep editing and extensive connectivity make it a flexible centrepiece for stage, studio and silent practice alike.

Authentic Feel, Digital Freedom

Developed in Italy by a team immersed in accordion culture, the FISA Suprema has been meticulously designed around real-world playing needs. Button sizes, spacing, angles and layouts have all been refined to feel instantly familiar to experienced accordionists, while the 120-bass left hand supports both Standard and Free Bass modes. Natural Bellows Response and Advanced Proportional Bellows Behaviour work together to track bellows movement and pressure in real time, so your phrasing, dynamics and expression translate exactly as they would on a premium acoustic instrument.

Global Accordion Sound in One Instrument

With 45 carefully modelled accordion types from around the world, the FISA Suprema can stand in for a full collection of traditional instruments. You can go further and design your own ideal accordion: choose reed combinations and footage, decide whether reeds sit inside or outside the cassotto, set your preferred tuning and temperament, and dial in growl, mechanical noises and even the perceived “age” of the instrument. This level of control lets you recreate beloved vintage boxes or craft entirely new voices tailored to your repertoire.

Deep Expression and Performance Control

Beyond its accordion engine, the FISA Suprema taps into Korg’s flagship workstation and synth technology to deliver a huge range of orchestral, organ, solo and synth sounds. These can be layered and assigned across multiple registers and parts, with up to 320-note polyphony ensuring complex arrangements remain smooth. Chin switches, a fully assignable master bar switch, touch sensors, aftertouch and a unique two-axis accelerometer give you powerful, intuitive ways to shape your sound in real time, from subtle vibrato and filter sweeps to dramatic performance gestures.

Stage, Studio and Silent Practice Ready

Onboard bi-amped speakers with 112 watts of power provide a full, clear sound for both player and audience, while headphone support makes late-night practice easy. Bluetooth Audio lets you stream backing tracks directly through the instrument, and MIDI, Bluetooth MIDI, USB MIDI and USB Audio ensure seamless integration with DAWs, sound modules and live rigs. With a lightweight 10.3 kg button layout, long-lasting rechargeable battery and clear colour LCD with easy and advanced operating modes, the FISA Suprema is built to handle demanding professional use without sacrificing portability or simplicity.

• Natural Bellows Response and Advanced Proportional Bellows Behaviour - Dedicated bellows modelling continuously tracks movement, pressure, number of keys pressed and pitch, delivering a playing feel that mirrors a fine acoustic accordion. Independent push/pull resistance, adaptive expression interpolation and seamless release on orchestral sounds make dynamic swells, shakes and phrasing feel completely natural.
• 45 Customisable Accordion Types - A comprehensive library of global accordion models removes the need to carry multiple instruments. You can fine-tune reed combinations, cassotto placement, detuning, mechanical noises, growl and virtual “ageing”, so the instrument can be voiced precisely for traditional folk, musette, tango, jazz or modern crossover styles.
• Huge Sound Palette with Hyper-Real Technologies - Alongside the accordion engine, you get more than 170 orchestral sounds, multiple organ types (TW1, TW2, FARF, VX and PIPE), Soloist and Synth patches, plus Hyper-Real Sound Cluster and Hyper-Real Drum Sounds Cluster for convincing band-like accompaniments. These sounds can be layered and processed with high-quality effects for rich, production-ready performances.
• Modern Connectivity and Portable Power - MIDI, Bluetooth MIDI, Bluetooth Audio, USB MIDI, USB Audio and dedicated audio outputs make the FISA Suprema at home in any modern setup, from solo gigs to full studio productions. The lightweight 10.3 kg button version, powerful bi-amped speakers, over 9 hours of battery autonomy and the ability to charge while playing give you reliable performance virtually anywhere.
