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.

This synth is its own little beast. With the adjusted filter you can certainly get sounds out of it that you simply can't reproduce on anything else. It was an odd first synth for me to figure out how analog works, but it's been well worth it. I would say don't worry about using it for sequencing, just enjoy playing with it - unless you're capable enough to mod it. Lastly, the neat thing is that there's really nothing to "compare" it to. It's kind of its own thing!

I bought a Delta for 350 Euros, and I love it! To give you an idea: I was able to play the opening of "Vienna"(Ultravox) on the Delta! The same sound and drumsound! The Delta can also produce fat sound effects! And I like the joystick.It will certainly play a role in my future tracks.Although there are musicmakers who are/were not happy with the Delta, I would warmly recommand this nice synth to every musicmaker.

SynthMagic has just released a Delta library for the Kontakt sampler.

The GUI is gorgeous and very tweakable: http://www.synthmagic.co.uk/delta.htm

Will become a classic. Filter sounds like an ms20 and the osc's are a sort of square wave.Fuzzy buzzy and warm electric!:that is the sound.
You hardly see them for sale any more, that in itself tells a story.

Pure analogue machine and it sounds incredible.
Strings are what analogue strings should sound like and the synth section with a choice of banpass filters can make gorgeous filter stabs and sounds.
Bass is lovely and warm on this thing.
Delta is a very cool synthesiser.
The people that score this a 1 simply must not know how to make good sounds ona synth.
I find the Delta easy to program and it is hard to amke it sound bad-Add some effects and you are away. Very unique sounding machine and now starting to be discovered for the gem it is.
