The Omnichord will be re-produced to commemorate our 70th anniversary

The Omnichord will be re-produced to commemorate the 70th anniversary of our company.


In the 1980s, the electronic musical instrument ‘Omnichord’ gained tremendous popularity among gadget-loving music lovers for its quirky look and tone. We have been receiving requests to resurrect the Omnichord for a long time. And this year, 2023, to commemorate the 70th anniversary of the founding of Suzuki Musical Instruments Manufacturing, we will reproduce the Omnichord! It is scheduled to be released around the fall of 2023. We will update the information on this page from time to time. *The photo is the old model OM-27.

What is Omnichord

It was developed as an electronic musical instrument with an automatic accompaniment function (auto bass chord) equipped with a harp sensor. Anyone can easily play chords, including those who are new to musical instruments and those who are less adept with traditional  instruments. It is played using multiple chord buttons lined up in the centre and a touch sensitive strum plate on the right. Whilst pressing the chord buttons, tap the plate with your finger or slide up and down to play 4 octave sounds to effectively accompany a song. Not only is it easy to play, but its unique appearance and tone makes it a hidden favorite both in Japan and overseas for artists who want to try something different and for non-musicians who want to play music!

History of the Omnichord

Originally development started with a request from an overseas sales company to make an electronic musical instrument like an auto-harp. It started with the electronic musical instrument ‘PC-27’ and the first Omnichord ‘OM-27’ was born with improvements to the interface and functions. Since then, as technology has advanced, we have created numerous models through trial and error in adding more chords, timbres, and designs.

About the form and size

NEWS 2023.4.25

The form and size have been decided!


The shape of the new Omnichord is based on the still very popular previous models of the OM-27, OM-36 and OM-84, with the curved shape on the left side of the body. In addition, the overall dimensions are one size smaller than the OM-27, making it a compact size that is easier to carry around. Regarding the OM-27, OM-36 and OM-84, which became the basis for the shape of the new Omnichord, we will introduce a little more information  along with the history of Omnichord.

[New model] Size: 460×250 mm

[OM-27] Size: 520 x 280 mm

OM-27 released in 1981

In these days the Omnichord is an electronic musical instrument used by a wide variety of different users, including artists and electronic musical instrument enthusiasts, both in Japan and overseas, but when they first went on sale in Japan, there was the concept of “Let’s ignore the fixed and difficult music theory and think more casually”. We aimed to create an electronic musical instrument, using our experience as an educational musical instrument manufacturer that could be used at home, at school, on trains, planes and ideal for adults and children alike. Although it is no longer available for sale, instructional textbooks were also made for those who play Omnichord for the first time.

About the form

The Omnichord is characterized by its streamlined body. According to ‘Omnichord Communication Paper No. 1’ published in Japan in 1982, this shape seems to express the thinking of a more futuristic musical instrument, with the shape as a motif, symbolizing the form of an overflowing happy tear. The body colour of the OM-27 was brown, red, and ivory. *The image is the colour lineup of the OM-27.

[OM-27 specifications] Size: 520 x 280 mm Weight: 1.7 kg Body color: Brown, Red, Ivory

[OM-36/84 specifications] Size: 520 x 280 mm Weight: 1.4 kg Body color: OM-36 (beige),

OM-84 (grey, ivory)

About specifications

The Omnichord is the world’s first electronic musical instrument with auto-accompaniment, equipped with an auto-harp sensor. Various functions were added to the successor models as technology progressed, but the style of playing by touching the chord buttons and metal strum plates lined up in the centre and being lightweight and easy to carry anywhere was already established from around this time. With the idea that “There’s no dream of a fully automatic electronic instrument! Let’s just sing the melody!” As a keyword, the OM-27 had a total of 27 chords of Eb, Bb, F, C, G, D, A, E, B Major, Minor, Seventh and the tone is one harp pattern. With the OM-36/84, major seventh and augment had been added, expanding the total to 84 chords. In addition, the OM-84 had two patterns of harp sounds, and a memory function that had enabled the player to record chords. This function was groundbreaking at the time, allowing you to play more freely. *The image is OM-84.
