The Strophonion is a sensor controller devised by Alex Nowitz for manipulating his voice in live-electronic contexts. It was initially developed at STEIM, using their expertise in hardware design as well as their software offerings, in particular LiSa and Junxion.
I got involved starting in 2014, when I helped building the next revision of this controller:
The electronics are largely the same as in the previous version, however we added an option to connect the controllers thru a cable in case the wireless system breaks down. The basestation though is a completeley new design.
Most notable are the 3D-printed shells which were designed and built by chihauccisoilconte. Here’s the new and old designs side by side:
In the following years, Alex and I embarked on a long journey to also update the other half of the instrument design, i.e. the software. The aim was to implement the signal processing in a more open, flexible, and expandable environment, so the complete functionality was transfered to MaxMSP. This process take longer than expected, but in late 2018 Alex was able to present the new version of the Strophonion in a concert as part of his PhD project.
Max patch for cutting fast between to video streams in realtime.
Zé Bif is Jens Brand on video and Marcelo Aguirre on drums.
4-channel switchable mic preamp mounted on trumpet. Phantom powered.
A DSP-based synthesizer that takes sensor input from a seismometer to generate a set of sine waves to drive transducers.
Sound modules for the walking sticks used by visitors of the “Speed of Light” project by NVA, Glasgow. Barometric and acceleration sensors control a small DSP that runs a composition by Chris Weaver of Resonance FM.
Two sets of headphone plus microphone exchange their sonic environemnt. Wireless.
Added two pan potentiometers to a vanilla DJ mixer. Together with the cross-fader they form a square of four tap-to-ground pots.
Modified guitar tuners to display words, pics, and patterns.
Includes DEAF, EDDY, DEFECT, EFFACED, 8
Frank mostly does his own sensor controllers. Here I just helped him to connect it to a wireless Eobody interface.
Like “Berlin, Mitte der Welt” this is a spinoff of the G-Player series. As usual (some of) the sounds are a 1:1 interpretation of topographic data, this time imprinted on a vinyl disk that sits on top of an elaborate object that alludes to planetary motion. Above a chandelier-pendulum with a laser pointer “scratches” across the disk’s grooves which in turn is sonified and played back thru a rotating speaker, part of the above object.
