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

Extended information

Of course, a modular system doesn’t just have advantages. Creative work with an audio construction kit like this takes time and practice, especially to start with. Anyone who wants to be able to check out all its available sounds at the press of a button will be very disappointed with a modular system. Each unique sound has to be puzzled out, and may never be exactly repeated. Nor are there any fixed rules for connecting the various modules. A modular is an open system, in which practically anything is possible, and that’s where the fun really starts. Diversity and experimentation - and sometimes lateral thinking - are the keys to its power. Although the user manuals for each module are very comprehensive, they can’t substitute entirely for a general overview and knowledge of analog synthesis. Some very good specialised books have been written on the subject, and although some may be out of print, it’s crucial to find one or two of them, and learn from them. With that, the whole world of modular systems will open up to you, and you’ll suddenly appreciate their fascination and sheer sonic power.

Technical specifications

The A-100 Basic System 2 is nearly identical with to the Basic System 1 but includes a MIDI-Interface. The modules A-150 (VC Switch) and A-162 (Trigger Delay) are replaced with with the MIDI interface A-190 and a 4HP blind plate.
