EMS Synthi AKS

The EMS Synthi A and the EMS Synthi AKS are portable modular analog synthesisers made by EMS of England. The Synthi A model debuted in May 1971, and then Synthi AKS model appeared in March 1972 a with a built-in keyboard and sequencer. The EMS Synthi models are notable for its patch pin matrix, its functions and internal design are similar to the VCS 3 synthesiser, also made by EMS. EMS is still run by Robin Wood in Cornwall, and in addition to continuing to build and sell new units, the company repairs and refurbishes EMS equipment.

When launched in 1972, the Synthi AKS retailed for around £450. An optional three octave (37 note) monophonic keyboard, the DK1 Dynamic Keyboard, was made available for it. Later on, the DK2 (Dynamic Keyboard 2) was released, allowing independent control of two oscillators, and thus enabling the player to play two notes together. The Synthi instruments were used widely in progressive rock and electronic music.
