The EWI was invented by Nyle Steiner, his second electronic wind instrument design. Steiner originally brought to market a brass style fingering analogue wind synthesizer instrument known as the EVI in the 1970s. Steiner then went on to develop the EWI which had a unique fingering system closer to the woodwind style. These instrument designs first working models appeared in the 1970s, with the EWI appearing commercially during the early 1980s.
