Following on from yesterday's System 100 announcement, Behringer has now revealed its new System 55 modules saying:
Let's switch on the time machine and go back to the sound of the 1970s. Introducing: Our Modular 55, 35 & 15 Series. We've got more than 20 modules for you – all authentic reproductions of the circuitry from the "Modular 55, 35 & 15" Series. And all brought to the Eurorack standard but still staying true to the era with some specific features.
That warm sound was loved by Artists from Tangerine Dream to Depeche Mode. And an earlier version used by Wendy Carlos on the famous album "Switched on Bach". That brought the sound of synthesisers into mainstream music and became basically the founding father of all synths in pop music.
