The Korg OASYS is a workstation synthesizer released in early 2005, 1 year after the successful Korg Triton Extreme. Unlike the Triton series, the OASYS uses a custom Linux operating system that was designed to be arbitrarily expandable via software updates, with its functionality limited only by the PC-like hardware.

OASYS was a software implementation of the research project that ultimately resulted in the OASYS PCI, a DSP card which offered multiple synthesis engines.^[1] The original OASYS keyboard concept had to be scrapped because of excessive production costs and limitations of then-current technology.^[2]

Production of the OASYS was officially discontinued in April 2009. Korg sold just over 3000 units worldwide.^[3] The final software update was released on November 24, 2009.^[4]

In 2011, Korg Kronos, a successor of Korg OASYS, was introduced at that year's NAMM Show.^[5]
