The EMS Synthi A, and a version of it with a built-in keyboard and sequencer, the
EMS Synthi AKS, is a portable modular analog synthesizer made by EMS in England starting
in 1972. Most notable for its patch pin matrix, its functions and internal design are similar to
the VCS 3 synthesizer, also made by EMS. E.M.S. is still run by Robin Wood in Cornwall, and
in addition to continuing to build and sell new units, will repair and refurbish E.M.S.equipment.
The Synthi AKS has been used extensively by Brian Eno in his art rock and ambient albums.
He particularly made prominent use of its signal-chain editing capability in order to add color
to his own voice as well as Robert Fripp and Phil Manzanera's guitar work. His early band,
Roxy Music, supposedly requested that he join them after watching him tinker with the Synthi
AKS for only a few minutes. Pink Floyd used the synthesizer to create the electronic riff of the
track "On the Run" from the 1973 album The Dark Side of the Moon.
