Korg DSS-1
A wonderful early digital synthesizer. With eight notes of polyphony, two oscillators per voice, a noise source, two multi-stage envelopes, a resonant filter and auto-bend, the DSS-1 has much in common with Korg's previous flagship DW-8000. But it went much further, boasting twin digital delays, oscillator sync, an improved unison mode, a lush analog VCF switchable between 12 and 24dB, and more. Whereas the DW-8000 got its raw material from 16 stored digital waves, the DSS1's oscillators take their source from sampling, additive synthesis, or even hand-drawn waveforms!
It actually had a warm sound and was great for creating pads and textures, as well as deep basses and drones. The synthesis method is based on altering various waveform samples via 2 data sliders. It can sample and then treat the samples as its waveforms - that includes all filtering and envelopes.


The DSM-1 (1987) was the expanded rackmount version.
It was used by Jean Michel Jarre, Joe Zawinul, Michael Cretu of Enigma, Mark Jenkins, Hiro Kawahara, Paul Nagle, Shriekback, and Steve Winwood.

One of the most interesting synths in Korg history
Installation is not for the faint hearted,took up a whole day and I spent twice the money for the mod than on he actual unit, but it's worth every penny.
Bright blue display, storage on CFcard/USBstick,24MB of memory (in 256kB chunks though), have all four systems off a floppy loaded at a time, but most important wav-file compatibility for transferring samples to and fro PC with the CF.
Didn't go for the SCSIinterface though, it's not needed if you got USB.
I got a new old favorite KORGsynth again
