Strophonion is a physical voice controler designed by Florian Gotke . and Alex Nowitz in 2010-11 at STEIM.
In 2014, after a few years of testing Alex asked me and Sukandar Kartadinta to build a backup instrument and improve the design of his instrument.
The new version of the "Strophonion" is lghter and shaped in a more organic way. It is made using 3d printing technology
The person using the strophonion in the pictures is NOT Alex Nowitz...
