SY_

The sy_ file extension was used for some compressed audio format in the Korg DW-8000 eight note polyphonic hybrid digital-analog synthesizer instrument. By the time of its launch Korg had already begun a common trend in 80s synthesizer design of using numerical parameter access as with the Korg Poly-800 eschewing the heavily laden control panels of earlier designs. A more unusual feature of the instrument for the time was the use of sampled waveforms as the basic building block of sounds, and the inclusion of a digital delay effect.
