A former agent of EMS in the [[United States]], Ionic Industries in Morristown, New Jersey, released a portable-keyboard VCS 3 clone in 1973. The ''Ionic Performer'', whose circuitry is based on the VCS 3's, replaced the patchboard matrix with over 100 [[push-button]]s, and added a built-in keyboard and [[effects unit]]s.<ref name=ionic>

The '''EMS Synthi A''' has the same electronics as the VCS 3, but was rehoused in a Spartanite briefcase. Instead of routing signals using [[patch cable]]s, like [[Moog synthesizer|Moog]] products, it uses a [[patch matrix]] with resistive pins. The 2700 ohm resistors soldered inside each pin vary in tolerance, indicated by different colours: red pins have 1% tolerance, white have 5%, and green pins are attenuating pins with a resistance of 68,000 ohms.

The later Synthi AKS incorporated an early digital 256 event KS (Keyboard Sequencer) [[Music sequencer|sequencer]] in the lid, with input provided by a capacitance-sensitive [[Buchla]]-style keyboard.

Perhaps its most prominent use is in  the introduction to [[The Alan Parsons Project]]'s ''I Robot.'' (1977). VCS 3 synthesisers were also used alongside a traditional chamber music ensemble for the soundtrack to the BBC's ''[[Life on Earth (TV series)|Life On Earth]]'' nature documentary series, composed by [[Edward Williams (composer)|Edward Williams]].<ref>Power, Mike.

Along with [[Klaus Schulze]] and [[Tangerine Dream]], other frequent users of the instrument include [[Cabaret Voltaire (band)|Cabaret Voltaire]], [[Tim Blake]] & [[Miquette Giraudy]] of [[Gong (band)|Gong]], [[Richard Pinhas]] of [[Heldon]], [[Merzbow]], [[Thomas Lehn]], [[Cor Fuhler]] and [[Alva Noto]].
