Why choose the Zenith One over other arrangers?
The Zenith One stands out for its simplicity and intuitiveness. Its compact and lightweight design (only 525 grams) features the largest touchscreen and Bluetooth connectivity on the market, offering unmatched flexibility with a 20-meter range.
Its streamlined interface, free of unnecessary buttons, ensures optimal human-machine interaction and perfect ergonomics, especially for musicians.
Furthermore, the Zenith One is ready to use right out of the box: Plug it in and play, thanks to a factory configuration designed for efficiency. It can also serve as an expander, allowing you to assign sounds to the chords and basses of your accordion without leaving arranger mode.
Fully customizable for the most demanding musicians, the Zenith One proudly combines simplicity, performance, and playing pleasure, all made in France.
Cutting-edge technology embedded in the Zenith One.
The Zenith One is equipped with a next-generation electronic platform, equivalent to that of our renowned Digit AiR, thus ensuring exceptional sound quality. Thanks to meticulous sound design, this arranger stands out with precise and transparent sound reproduction, featuring a sound bank specifically developed to meet our demands.
We’ve innovated with HSLG (Human Strumming Live Guitars) technology, allowing real-time reproduction of a professional guitarist’s playing. To achieve this, we collaborated with renowned guitarist Tony Margalejo and conducted numerous studio sessions. The result is stunning realism, with recordings of acoustic guitars, electric guitars, and much more.
Immerse yourself in an immersive sonic atmosphere, with samples specifically crafted for the styles of our arranger, whether it’s musette or variety.

Chord Pro: A New Universe
Chord Pro is arguably one of Zenith One’s key features that sets it apart from all other arrangers. This new Chord Pro mode may change your habits. You can now edit your chord charts directly without needing to play them. The advantages are many. If you want to work on a melody, Chord Pro can provide rhythmic support without you having to play the harmony. If, however, a piece of sheet music proves challenging for you in terms of harmonies, Chord Pro will relieve you of that task, allowing you to focus on your singing or melody. Transposable without quality loss, your chord charts will be saved, and you can even interpret them in another style, as well as share them with friends who also own a Zenith One.
Unique and unmatched sounds with the Zenith One.
The Zenith One features exceptional accordion sounds directly derived from our renowned Digit AiR. You’ll have access to iconic sounds such as the Celeste Azzola, the 3-Voice Musette, the Plein Jeu, the Bassoon, the Double Bassoon, the Steirisch, as well as diatonic accordion sounds, an Alfred Arnold bandoneon, three accordinas, and international accordion sounds with piano keyboards.
In addition to these accordion sounds, the Zenith One also offers a vast GM sound library, with 600 presets categorized by family (pianos, violins, organs, saxophones, trumpets, guitars, voices, synths, etc.). You can layer up to five sounds per keyboard—15 in total—offering even greater sonic richness with top-tier quality and unparalleled natural realism.
Exclusive and diverse styles with the Zenith One.
The styles offered by the Zenith One are entirely new and exclusive. Unlike older models like the AiR Symphony, we haven’t simply replicated existing styles. Why? Because we aim to offer users genuine innovations, allowing them to discover truly fresh and usable styles.
The Zenith One provides an extensive sound palette, with both international and French styles. You’ll find ballroom dance styles, modern styles, and nods to French music, German references, 60s to 2026s hits, and Creole repertoire. The goal is to offer a complementary alternative to traditional arrangers.
We have also reworked repetition cycles, even for musette, extending cycles up to 16 measures instead of the traditional 4 or 8. This eliminates monotony and brings stage dynamics, offering a more lively and engaging playing experience.
Exclusive and expandable styles.
We firmly believe that the quality and originality of styles are at the heart of the arranger experience. That is why we will regularly release new style packs to further enhance the Zenith One. All of these additional styles will be provided free of charge to our users, ensuring a continuously evolving, innovative, and inspiring musical experience.
Built-in Expander Mode.
The Zenith One easily transforms into an expander, allowing you to assign different sounds to the various sections of your accordion (right hand, basses, and chords) without leaving arranger mode. Dedicated, ready-to-use presets are included, making setup quick and effortless.
Unlock the full sonic potential of your MIDI accordion or MIDI keyboard with the exceptional sound quality of the Zenith One. For the most demanding musicians, it is even possible to layer up to four sounds simultaneously.
High-Quality Customer Support.
The Zenith One’s after-sales service is based in France, in Béligneux (Ain), at our own manufacturing facility. Should you ever need assistance, simply send us your device. Thanks to its compact format, shipping is easy and cost-effective.
Service turnaround time is exceptionally fast: if your Zenith One arrives at our workshop on a Monday, it will be serviced and ready for return within a maximum of 48 hours. This ensures minimal downtime and allows you to get back to making music as quickly as possible.
Comprehensive User Manual.
The user manual is supplied in printed format, in full color, with clear illustrations for every step. It is written in French and provides detailed guidance throughout. Video tutorials are also available to help you get the most out of your Zenith One.
Sound Mixer: A Practical and User-Friendly Feature!
With the Sound Mixer, you have complete control over the volume levels of the arranger’s different sections. Quickly and easily adjust the volume of the drums, bass, orchestration, or solo sounds to create a perfectly tailored musical experience.
Fully Customizable Styles with the Zenith One
The Zenith One comes with carefully crafted and perfectly balanced styles, providing a high-quality foundation right from the start. However, you are free to make your own adjustments and save them according to your preferences.
You can modify the tempo of each style, edit its content, and replace sounds with others—for example, changing the bass sound or adjusting its volume within a specific variation. Every variation and every style is therefore fully customizable: tempo, volume levels, reverb, panning, chorus effects, and sounds can all be tailored to your exact needs.
In addition, each style features a memorized master volume, allowing you to balance overall sound levels without affecting the internal mix between the different parts.
Finally, the Zenith One includes 360 registrations, enabling you to instantly recall your favorite styles and save your settings completely independently.
With the Zenith One, every style becomes your style.
MIDI Compatibility and Advantages of the Zenith One
The Zenith One is fully compatible with all standard MIDI accordions and MIDI master keyboards. If your system supports it, you can directly access and control every style and sound of the arranger from your MIDI accordion or keyboard.
Designed specifically for accordionists, the Zenith One takes into account every bass note transmitted by the instrument. This allows it to perform precise bass lines, passing notes, and harmonies that faithfully follow your playing, delivering an authentic and highly personalized musical experience.
The Zenith One adapts to your instrument, so your music remains uniquely yours.
MP3 Playback and Lyrics Display with the Zenith One
The Zenith One allows you to play your MP3 files with ease. You can organize your MP3s into folders and create shortcuts for quick access to your favorite tracks.
It is also possible to program the automatic playback of a sequence of files, providing a smooth and uninterrupted listening experience.
In addition, the Zenith One supports MP3 files with embedded lyrics. If your files do not already contain lyrics, you can easily add them, and they will be displayed automatically during playback. The Zenith One also supports MIDI files.
