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.

IS THERE ANYONE THAT HAVE A ROM COPY...???
I think my DSS1 has lost the eprom data....I powered it up after 1 year and now the display show only black dots....I've tried to replace the cpu and 8155 controller without luck...
The only downside so far: a broken disk drive.
Damn, this thing sounds like it looks: Huge, fat and warm. I won´t sell mine for sure. I´m so in love with this synth/sampler/thingy.
totally agree with you about the Operating System and is one of the downfalls of the DSS-1 /DSM-1 IMO. I think it's the one thing that lets this beast down. If you're looking for one make sure the fragile disk drive still works as replacing is a pain. Also watch out for poor key triggering as it suffers from the same "iffy" keyboard mechanism as the (brilliant) DW-8000. Big fat analog sounds from the DSS-1 though if you can find room for it :) They rarely go for more than a few hundred $'s so defo worth checking out and can sound huge in the right hands.
