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.


What can be found on this website

The website is organized into five sections:

Cologne, 1987 (Lomography: © Matthias Groebel)

Original CD productions and some additional musical impressions. Pieces and excerpts of recordings from 40 years - and also a few vintage posters.

sample-imageQuite a sensation for me! Metric Halo, Make Believe Studios and Sontec have released a digital replication of the Sontec MES 432 D9 Mastering Equalizer. And that's just not all!

It just was that kind of feeling.

My favorite instrument for live electronic music turns 30!

Some patches make my daily life easier in such a pleasant way that I offer them for download. In order to run the patches on the computer (Mac or Win), you will need (the free version of) "Max/MSP" by Cycling74.

And I heard another voice from heaven saying,
“Come out of her, my people, lest you share in her sins, and lest you receive of her plagues!
"Eat ze Bugs!"

"We are the CO2 to be reduced!"
