Magna Organ introduced in 1935,[7][8] was a multi-timbral keyboard instrument invented in 1934 by a Yamaha engineer, Sei-ichi Yamashita.

[note 1] Early designs of the Magna Organ were a kind of additive-synthesizer that summed-up the partials generated by the frequency-multipliers.

[11] According to the additional patents[12][13] and the reviews at that time,[9] its later design as finally implemented, seems to have shifted to the sound-colorization system using the combinations of sets of free reeds, microphones and loudspeakers.

Note that, similar type of instruments using the pairs of free reeds and microphones sealed in double-soundproof boxes, were later re-commercialized as Croda Organs in 1959 by Tōyō Denshi Gakki Kenkyūjo (In English: Tōyō Electronic Musical Instrument Laboratory) in Tokyo.

The wind and lip pressure information is converted to MIDI data which is interpreted by the external sound module.

On the 1991 CD release "Love In" by the Australian band "The Freaked Out Flower Children" (Discogs: https://www.discogs.com/release/4281005) Sophie Lee is credited as playing the WX11.

Between 1950 and 1998, the Yamaha Corporation produced a form of outdoor warning siren which was designed to play music, rather than alert the public of danger.

These were created by the president of Yamaha at the time to harness the sheer sound output of a siren to play music, and to ease the fears and memory of war and air raids for the public.

These sirens became "symbols of peace" and were widely installed on department stores and city halls.

Most of these musical sirens have been decommissioned as parts became scarce or unavailable, although some units remain in service today.

It was also a more compact model than the original, which was accomplished by putting the rotors in stacks to minimize space.
