VCS 3 - 1969 The company's first commercial synthesizer, it was produced in 1969. Designed by David Cockerell & developed in the basement of Zinovieff's house. Their aim was to create a versatile monophonic synth that would retail for only 100 pounds. The VCS retailed for about 330 pounds, less than it's American competitor, the Minimoog.
The VCS 3 contained 3 voltage controlled oscillators, a noise generator, two input amplifiers, ring modulator, , voltage controlled low pass filter, trapezoid envelope generator, voltage controlled reverberation, level meter, two output amplifiers thus providing a stereo output, and a joystick providing 'X' and 'Y' modulation control.

Synthi 100 - 1971 With the development of this synth, EMS went into direct competition with Moog. This system was mounted in a free-standing console cabinet and it used the same technology as the VCS3, being in essencethree VCS3 units combined. It wasdriven by twelve VCOs and featured a built-in oscilliscope, two 60 x 60 patchbays, two joystick controllers, dual five-octave velocity-sensitive keyboard controllers and a 3-track, 256-step digital sequencer.

Synthi A/ Synthi AK/ Synthi AKS - The Synthi A was a portable version of the VCS3. The Synthi AK was an expanded version, retailed at 420 pounds. It featured a sequencer and a small keyboard built into the lid.
