C::NTR::L (Marco Donnarumma, 2006 – 2010) is focused on live performance practice and audiovisual improvisation. The application’s core and interface are built with Pure Data graphical programming environment.

The software seeks to help musicians to perform a non-standard real-time audiovisual processing using an unmodified fretted instrument such as bass guitar, guitar, piano, accordion, etc. Thanks to a real-time pitch detection system C::NTR::L translates in real time the sonic gestures of a performer into control parameters for audio and video processing.
C::NTR::L is dedicated to musicians who wish to add real-time effects in their concerts without loosing the impact of their liveness on stage, to artists working with audiovisual live projects who feel the need for a more performative approach. Forget your mouse and keyboard, hold your guitar and create your performance or concert step by step playing your instrument.
