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.

The DSM-1 is expanded in some areas as the article indicates, but cut back in other areas and just different in still other areas vs. the DSS-1.
Expanded: It has double the sample memory of the DSS-1, and uses DS-HD floppies vs. DS-DD.
Cut back: It does not have the dual digital delays that give the DSS-1 much of its character. Also the resonance of the VCF's on the DSM-1 is not adjustable.
Different: Rather than 8 voices with 2 VCOs each (sync-able to each other), it has 16 voices with 1 VCO each (non-syncable).

I love it since i got it for 140€. I have been nagging the seller for about 1 year. Now It´s mine.
Damn great synaptic of analog and digital. Only Bug: dead floppy drive - it can be replaced by a lot of usual floppies on the market. Just look for schematics or mod manuals on the net (like comodore amiga floppy mods, as an original a500 drive worked fine on my dss-1 - no jumper settings needed to be changed). For som other models you need to solder a bit around.
