-The '''Formant''' [[analog]] [[modular synthesizer]] designed by C. Chapman was published in 1977/78 as a series of articles in the European magazine [[Elektor]]. The articles were later compiled into a book and a year later there was another book, (not in English) with additions and extensions by M. Aigner.

 === Front panels ===
 The front panels are 6U to match up with the size of the double [[Eurocard]] (200 mm x 160 mm) VCO PCB, the other PCBs are single [[Eurocard]] (100 mm x 160 mm). This was already a standard PCB format for Elektor projects.<ref>[https://modwiggler.com/forum/viewtopic.php?t=84426&start=25 Elector Formant synth], Mod Wiggler Forum, Dec 2013</ref>
