If you've had any exposure to modular synthesizers, chances are you'll have seen some Doepfer modules. Dieter Doepfer sarted to build right from studying physics, with a phaser module for the Formant Synthesizer then the single voice MS-404. , Thanks to him, the Eurorack module format has become a standard - adapted from the scientific rack testing system tweaked to work for synthesis. He doesn't want to take much credit, but in reality, a better power system, internal CV and Gate bussing, plus a lower cost ribbon connector system required some innovation and in my opinion has had a major impact in the proliferation of modular synthesizers in recent years.
Currently in the Doepfer range there are 171 modules, racks and accessories (from a quick search at Thomann) - so he's been busy!
At the Alex4/ Schneiders Laden booth at t Musik Messe earlier this year, we had a chat with Mr Doepfer about his beginnings.
