Engineering a world of sound

Doepfer Musikelektronik GmbH is a manufacturer of audio hardware based in Germany, founded by Dieter Doepfer.

A-100 Analog Modular System

In the A-100, Doepfer have produced a capable and versatile analog modular synthesizer, built in the style of the classic modular systems of the seventies. The renaissance of analog synthesis in the last few years shows that analog sound production has a vital place alongside sampling and digital synthesis, and can produce sounds that are unobtainable by any other means.

Modulation Opportunities

In addition to the unique sounds of its oscillators, filters, amplifiers, phasers, frequency shifters, and so on, analog synthesis can provide almost unbounded modulation opportunities, conventional and unconventional - limited only by the number and variety of modules available.

Setting Priorities

In designing the A-100, our priorities were: good sound quality, diversity of modules available, ease of integration into a MIDI system and, maybe most important of all, affordability.

A-140, A-180-2, A-138b, A-110 and A-132-3 are among Doepfers most popular products.
