C.A.M.R. (Computer Aided Musical Research)

C.A.M.R. is the umbrella term for most of my musical activities combining acoustic and electronic instruments since 1989. The intended idea has always been that of the "electronic guerrilla" - i.e., the realization of electronic instruments that are playable in real time and can be transported easily.

10 years after departing from all universities and state-subsidized institutions, the "Mobile Studio" was launched in 2014 in order to work independently - from concert sound reinforcement and recording to the edited and "mastered" audio document.
