Endangered Guitar

"...a killer tour de force of post-everything guitar damage"

Larry Nai, Signal To Noise

Guitar-Controlled Live Sound Processing

The Endangered Guitar is a journey through the land of unending sonic operations, an interactive hybrid between a guitar and a computer. The software “listens” to the playing, to then determine the parameters of the live sound processing.

The guitar is the sound source, but the same sound is also used to control the software. Sounds of the guitar are processed in realtime, pitch and various other parameters of the actual playing serve as control source of the processing. As of 2017, these parameters are also affected by data from Hans Tammen’s own DNA analysis.

Multichannel Works

Under the name “Prozesshansl” the software has been further developed to allow for sound input from other players to be processed. Instead of the guitar, audio from these players is used to control the parameters of the live sound processing. Read here…
