Therevox

In 2010, Therevox was commissioned by Montreal's Breakglass Studio 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 design included a built-in spring reverb and this prototype became the ET-4 model that has been available since 2012. 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. The instrument is currently housed in Live Room B in StudioBell and is a part of the National Music Centre's "Living Collection". According to the online marketplace Reverb.com, the ET-4 was one of the most watched synthesizers of 2023. In March 2021, the Therevox ET-5 was announced and began shipping to advance customers shortly afterwards. There is currently a two year waiting list for a new Therevox ET-5.
