Therevox

The company focuses on continuous-pitch instruments and is known for building a modern analog synthesizer inspired by the rare Ondes Martenot.

[1] First commissioned in 2004 to build modern version of the Electro-Theremin as used by The Beach Boys on their 1966 single "Good Vibrations", only 12 of these instruments went to musicians and studios in North America and Europe.

[2] In 2010, Therevox was commissioned by Montreal's Breakglass Studio[3] to build a new instrument and designer Mike Beauchamp combined the Ondes Martenot's au ruban and touche d’intensité interface with a dual oscillator analog synthesizer similar to the MiniMoog.

The last ET-4 ever produced was acquired by Canada's National Music Centre in 2019 under the condition that the instrument continues to be made available to musicians.

[9] The ET-4 and ET-5 have also been used on soundtracks for Planet Earth III, Hulu's The Handmaid's Tale (TV series), The Walking Dead: Dead City,[13] Halo Infinite,[14] Bad Banks, The Inventor: Out for Blood in Silicon Valley and horror film Nurse 3D starring Paz de la Huerta and the Salvatore Ferragamo inspired "White Shoe".
