Around 1964 the first Moog synthesiser [1] made its appearance – an (entirely analogue) modular electronic instrument that revolutionised the music world with its sound possibilities. The Moog was manufactured in various forms until 1980. This synthesiser formed the inspiration for many music projects – including the Elektor Formant from 1977, which continues to enjoy a lot of popularity [2]. The home lab of Kurt Diedrich, which we visit in this episode, is also the birthplace of a Moog-like synthesiser – a project that is under continuous development and is eminently suitable for DIY, not least because it uses readily available and affordable components.
