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.

I owned a delta from 1980 - 1989. Very versatile polyphonic synth for the money. Mixing the synth and strings led to thick sounds. The synth filter cutoff and envelope controls offered great sound flexibility. The brass sounds came through in recordings loud, thick and clear.

I got one given me! Normally used to CS80's, CS70's, Jupiter 8's, Oberheims, Moogs, Hammonds, Clavinets and the like - I found it very interesting and useful. My other Korgs - Sigma, Mono/Poly, Poly6, MS10 and MS20 and also a MicroKorg. The Delta is in good company!

Piece of crap?? One star rating..??
The Korg Delta is one heck of a magic-wonder pad machine, and more. There's so much you can do with the very groovy sounding filter which has also a BAND PASS mode. I think it more as a synth than a stringer. The strings aren't the best but still a very unique sounding bonus.
Delta is one of my personal favourites, and it even has a trig input for sequencing.

I owned this piece of crap from '82 to '90. One of the worst, thinnest sounding synths I've ever played. Absolute crap. The only thing it was good for was putting the string section through a distorted amp for an approximation of a mellotron.
