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.

I'm a synth service engineer and have the schematics for all Korg synths and let me tell you the facts: Filter=analogue,filter envelopes=analogue,amp enevelopes=analog,lfo=analogue...I could go on. These are the facts.
@gabos get your facts straight-It is not a true analog poly synth and I don't think it want's to be; It has it's own unique sound that can pull off analog, but also makes unique unworldly sounds that cannot be replicated by anything else.
My advise? If you have one do not even think about selling it.
At the moment they do not know that what hides beneath that smooth black casing is an analogue poly synth that puts most others to shame....£5000 for a Jupiter 8 LOL do me a favour. Grab a DSS-1 and learn what analogue pads should sound like.
The bass on this and Unison mode would bury a Jupiter 8.
Let the analogue anoraks sleep on this one so the price does not sky rocket.
