A Synthesizer 50 Years In The Making

Tim Blake (Gong, Crystal Machine) with the EMS VCS3

1969 was a groundbreaking year with regards to modular synthesizers. Leading the way was a brand new company called Electronic Music Studios (EMS). Led  by Peter Zinovieff, Tristram Cary and David Cockerell, their aim was to create a versatile monophonic synthesizer at an affordable price to help entrepreneurial artists and engineers take their musical compositions in exciting new directions. Their first release, the VCS3, retailing for far less than its competitors at just £330, proved to be their first success. The VCS3, short for (Voltage Controlled Studio, version #3) was a portable analog synthesizer with a flexible semi-modular voice architecture. Nicknamed “The Putney”, after the London suburb where EMS co-founder Peter Zinovieff was living at the time, the VCS3 has left its mark on many of the greatest musical compositions of the modern era.

From the innovative sonic textures of Pink Floyd’s “On The Run” to the unmistakably pioneering filtered-organ intro to The Who anthem “Won’t Get Fooled Again”, the VCS3 has been a principal character in the history of popular music for the past half-century. All in all, the VCS3 as well as other classic synths from EMS have graced the recording catalogs of some of the most inventive artists of all time, from Brian Eno, Hawkwind, ELO, Kraftwork and Led Zeppelin, to more modern acts such as The Chemical Brothers, Aphex Twin, U2 and LCD Soundsystem.

But even more legendary than the VCS3, is the VCS4…a prototype that was never put into production. It effectively comprised two VCS3 synths, a five-octave keyboard, a mixer and a signal processing unit, all assembled in a single wooden cabinet, for convenience and portability. And now, finally, with the blessing of EMS co-founder Peter Zinovieff, XILS has launched the XILS 4, the powerful and versatile digital recreation of one of the rarest pieces of equipment in music and recording history. Not only that, but they have also included a ton of brand new features making it even more dynamic and practical than its mythical analog predecessor.

Introducing The XILS 4

The XILS 4 emulates a prototype that was never released, the EMS VCS4, and was based on two intricate and interacting VCS 3 cores, highly used synths in the 70’s by artists like Pink Floyd, Brian Eno and The Who.  Those cores were then coupled with the famous 256 analog polysequencer.

The XILS 4 retains the unique sonic character of the original, and also some of the quirks while adding a host of new features.  It’s an endless source of inspiration for those who want to go deep into the heart of Analog Modular Synthesis.
