Topophonien

The Topophonien project marks the point at which I turned my hobby of building music-related electronics into a job. Prior to this I had mostly tinkered with various guitar effect circuits, so when Sabine Schäfer approached me in 1990 with a request if I could build her a computer controlled spatialization mixer this was a rather tall order. Starting with a small 4×8 matrix with noisy VCAs and limited control, we expanded over the years to ever bigger systems with up to 40 DSP-driven channels and realtime spatialization control.
