context_page_description: The VCS 3 is a portable analog synthesiser with a flexible semi-modular voice architecture, introduced by Electronic Music Studios Limited in 1969.
  EMS released the product under various names. Logos printed at the console's front left say "V.C.S. 3" on the most widely sold version; "The Putney" on the earlier version; and "The Synthi II" on the later version.
context_section_description: Although the VCS 3 is often used for generating sound effects due to lack of a built-in keyboard, external keyboard controllers were available for melodic play. The DK1, produced in 1969, is an early velocity-sensitive monophonic keyboard for VCS 3 with an extra VCO and VCA.  In 1972 it was extended for duophonic play as DK2.  Also in 1972, the Synthi AKS was released, as well as a digital sequencer with a touch-sensitive flat keyboard, the KS sequencer, and its mechanical keyboard version, DKS.
