Korg Delta

Korg Delta Image

Korg's Delta is an analog semi-poly synth/string machine, basically a slimmed down version of the Korg Trident. Though limited in the range of sounds compared with other synths of the same genre, the sheer quality of the sound from this little beastie really does make it something of a marvel. It can be found used for cheap and is worth it for the retro synth strings and fat bass synth tones.

The synth is split into two sections, Strings and Synth, for which there are separate audio outputs along with a combined output for headphones or mixing. Each section has its own controls. The String section has two pitch sliders (16' and 8') along with two tone controls (Bass and Treble) and variable Attack and Release controls to modify the sound. The Synth section has four pitch sliders (16', 8', 4' and 2'). There is also a white noise generator along with a very effective 24dB/oct low pass filter (high pass and band pass options are included too) and full ADSR controls. The synth has no memory storage or MIDI, however it does has voltage control and gate ins and outs.

The string sounds are very basic but with its separate outputs and when mixed together with the polysynth you do get that classic 'layered' sound which is useful enough on this synth; and it's fully polyphonic, so you wont be running out of notes! There is a handy joystick to the left of the 49-note keyboard for pitch bending and modulation capabilities. The construction is solid and heavy partly due to the implementation of a wooden base but also because it was designed for heavy usage on the road. Added bonuses: noise modulation, stereo out (strings/synth split), and the ability to combine synth and strings or turn off oscillators in the mixer section. It has been used by the Human League, Bitch Cassidy, Flock of Seagulls, Ladytron, Zensor and Broadcast.

Korg Delta is actually the best Synthesizer of it's kind. I had the Korg Trident which is of course a bigger syntheszier but actually I found myself playing more with Korg Polysix and Delta, that's why I sold it. I would suggest buying one before it goes more than 1000 Euros and become very rare. It's filter is a killer and strings have great quality for an electronic instrument. Their combination is unique.

Delta is a really cool little synth. The strings put me a bit off in the beginning but with clever layering with the synth section and some individual routing to external effects this becomes a wonder-pad machine!
The filter is super good. Route it's control to the joystic, and the band-pass mode along with external trigger for the notes makes Delta an instant acid-synth too!

Sometimes the nature of being paraphonic makes playing long release pads and strings a little awkward. You can overcome a little by practising the playing technique with it.

We will not end our auctions early as we hope to raise the highest amount possible for a great cause. Best wishes, Lee.

Got this synth off gumtree for £450. I totally recommend anyone who's thinking about getting ahold of one to go for it!! The filter is absolutely beautiful and has a really distinct character. A few people said they thought it sounded like the MS20 filter - there's definitely similarities but the Delta has a distinct quality to it that makes it stand out from the crowd in my opinion. The bass is rich and full and the oscillators tone is buzzy and full of character. Most of all, it FEELS good. Have used it in the studio and live. Totally ripping with a distortion pedal... Great strings too.
