Three engineers and a wooden controller.

Expressive E describes itself as a French company “founded in 2013.” Its founders were three engineers: Eric Simon, a UTC-trained engineer specialising in industrial design; Victor Grimaldi, also from UTC; and Alexandre Bellot, an ICAM engineer specialising in industrial sciences, according to a February 2016 profile by Est Ensemble, the public body for Montreuil and neighbouring towns east of Paris. The French company register dates the legal company to January 2015.

The same profile gives the early history. The technical principle behind the company’s first product was patented in 2013, the year SATT Lutech, a technology-transfer company, invested €170,000; a prototype was developed and patented in 2014. Expressive E was supported by the Paris incubator 104 Factory in 2014 and 2015, then moved in early 2016 into the Atrium business nursery in Montreuil, with about a dozen staff.

That first product was Touché, a small controller with a wooden top. The company’s 2015 website said its wood surface was designed “to react to the smallest vibration, the slightest pressure of your hand,” and it was shown at the Winter NAMM show in January 2016. Sound On Sound, reviewing it in November 2017, described a USB, MIDI and control-voltage controller whose wooden surface is held by magnets on an assembly that floats on silicone cylinders, so it can be pressed and pushed in several directions. It came with Lié software, including presets for more than 130 software synthesizers, and cost £349, or $399. The reviewer said he could think of no other hardware controller offering the same intuitive, three-dimensional physical freedom of expression. The pitch was simple: to give electronic instruments some of the physical feel of acoustic ones.

A keyboard built with Haken Audio.

The company’s best-known instrument is the Osmose. Announced in November 2019, it was presented as the result of more than seven years of research and development, MusicTech reported. Unlike ROLI’s Seaboard or the KMI K-Board, it uses a mechanical keyboard; each key can be pressed further after the note sounds and wiggled sideways, so pitch, vibrato and tone can be shaped note by note. Expressive E calls this “3-axis motions for every key.”

Inside is the EaganMatrix synthesizer, the same engine used in the Haken Continuum, and the Osmose is a formal collaboration between Expressive E and Haken Audio, Sound On Sound explained in its April 2023 review. Lippold Haken, inventor of the Continuum, is a professor at the University of Illinois; Edmund Eagan developed the editor and leads the sound design. The pandemic held up production — the Osmose was due in 2020 but reached buyers in volume only later, Sound On Sound noted, at £1,659, or $1,799. Its verdict: “a paradigm‑busting, deeply expressive synth and MIDI controller.”

The company has also built a software line around expression: Imagine, a physical-modelling instrument reviewed by Sound On Sound in 2022; Noisy 2, a soft synth, in 2024; and Soliste, a suite of modelled solo instruments, in 2025. In November 2025 it added the Osmose 61, with a five-octave keyboard, at $1,999, Attack Magazine reported, and in 2026 the Osmose CE, a “Controller Edition” without the onboard synth, in 49- and 61-note sizes at €999 and €1,199, according to Sound On Sound.

Expressive E says Hans Zimmer used the Osmose for sound textures on the score of Dune: Part Two, a story Sonicstate covered in December 2024; it also names Jean-Michel Jarre, Flying Lotus and Mike Dean among its users.

Design and documentation.

A controller keyboard makes no sound of its own: it sends MIDI, the standard that lets instruments and computers talk to one another. Dave Smith demonstrated it at the Winter NAMM Show in 1983, and the specification was published that August, English Wikipedia says. A newer extension, MIDI Polyphonic Expression (MPE), which lets each note in a chord be shaped separately, was adopted by the MIDI Manufacturers Association in January 2018.

Two makers here share an owner. Akai Professional and M-Audio belong to inMusic, the private group in Cumberland, Rhode Island. Jack O’Donnell, its founder, bought Akai Professional in 2004 or 2005 — sources differ — and inMusic took over M-Audio, founded in 1988 as Midiman, from Avid in July 2012.

The others are smaller. Nektar Technology is “California-based,” Sound On Sound wrote in 2019; the company dates itself to 2009. Keith McMillen Instruments, of Berkeley, California, announced in September 2024 that it was rebranding as Muse Kinetics. ROLI, maker of the Seaboard, is London-based; after its original company entered administration in 2021, a new company took over the brand, English Wikipedia says.

Two are European. Expressive E calls itself a French company founded in 2013, and its legal notice gives a registered office in Marseille. Studiologic is a brand of Fatar, the keyboard-mechanism maker founded in Recanati, in Italy’s Marche, in 1956; Fatar says it has factories in Recanati and in Tunisia.

This guide sets out what can be checked about each brand — who founded it, who owns it, and what it says about where its products are made — and marks clearly what rests only on the company’s own word.

Designed in France, now built in Poland.

Where the instruments are made has changed. The company says the Osmose is “designed in France,” and describes it as made with 66% recycled materials and assembled without glue so it can be repaired. In November 2025 Attack Magazine reported that, with the opening of a Polish factory, Expressive E had moved Osmose production out of China and brought it in-house, with the Osmose 61 assembled in a new company-owned facility in Poland. Sound On Sound referred in June 2026 to the company’s move in 2025 to “in-house manufacturing in Poland.” We found no statement of where the Touché is made in the sources we checked.

The base has moved too. The company’s legal notice gave a registered office in Montreuil in 2019 and 2023; today it names Marseille, and the French company register shows a Marseille head office trading since 2024. The publisher, a simplified joint-stock company named Expressive, lists Alexandre Bellot, one of the three founders, as publication director. We found no record of an outside owner in the sources we checked.

The brand itself is restrained: the instruments use black casings, and the Touché pairs a soft-touch base with a wooden top. The company has not published brand guidelines, colour values or typefaces, so the palette here is our reading of its products.

For a design guide, Expressive E shows how a small French engineering company can build an identity on touch and materials rather than on logos. Compare ROLI, whose Seaboard took expressive playing in another direction, and Arturia, another French music-technology maker. For this guide we use black, maple, walnut and white with a sans, an unofficial interpretation; no product or logo is reproduced.
