KORG 700S (Mini-Korg K-2)
| Top/Intro | 700 & Me | Mods | Links | Files | Soundz | 700S #2 |

My 1st Korg Mini-Korg 700S (Univox K-2)...

This is like the brother of the 800DV, but in fact it's the cousin (the brother should be 770).

This 700S came like this, a bit scratched on the casing, but otherwise it's in quite good conditions;

The 700S is an enhanced version of the Korg Mini-Korg 700, with added 2nd VCO and Ring Modulator - all controlled by the extra side panel on the left.

Well, I've modded it a bit... quite a bit....  haha... spot the difference!

The Korg 700 and 700S
Korg 700 and 700S basically share the same circuit boards, except that the Korg 700S has an extra PCB inside, and also extra sliders and switches on the left of the keyboard - which is basically the additional Ring-Mod circuit.
However, the basic sound structure and the main synth and the 3 main PCBs inside are identical.

Mini-Korg 700S and C Y
bulletI always liked to have a Mini-Korg 700, or 700S. In fact i got the 800DV because i wanted to have something along the lines of a 700S.
bulletWidely used by a lot of artists, including Will Gregory of Goldfrapp. Has similar Traveler VCF Controls as the 800DV, also features REPEAT, Portamento, Vibrato, Delayed Vibrato and a slightly less controllable BENDER - 800DV you can control Bend UP or DOWN and also Bend Time, but 700S, it's all fixed, just an On/Off switch.

bulletAgain, very playable and easy to get some interesting soundz and noizes.
bulletThe casing, layout are quite nice, and less complicated/annoying as the 800DV. Just remove the top cover, remove the keyboard and side panel, all PCB's are underneath, simple.
bulletIn fact this is my 2nd 700S, I got another one but it hasn't been posted to me yet (the seller has an accident), but i also by chance got other spares for the 700S - spare filter PCB, spare VCO PCB, spare Ring Mod PCB and spare PSU board that I could actually build a rackmount 700S.
bulletAlready modded the 800DV, I know modding the 700S is not difficult. In fact i was thinking too much ahead of time!!!
 
I haven't got it midi-ed yet, because it requires Hz/V and I dun have any Hz/V Midi-to-CV converters here at the moment, but will definitely do so.

Some Korg 700S Soundz
The possibilities of sounds that the Korg 700S can do are far too many. Here are just a few examples...
bullet 700S Traveler
 The Traveler is basically a High Pass and a Low Pass Filter.
This is just sliding the 2 at different positions, thus changing the filter...
bullet 700S The Bender & Portamento
 The Korg 700S (and 800DV) has this Bender switch. It is not a Pitch Bend. It is not portamento either. It is just to bend the start point of the sound.
This file: 1st is Normal, 2nd is with Bender On, 3rd is with Portamento On.
bullet 700S Switches
 Playing the Korg 700S then turning on some of the switches
- Expand, Bright, Bender ...
bullet 700S Ring Mods
 700S has the Effect section which has the 3 Ring Mod FX.
This file: switching thru the 3 Ring Mods, changing the Pitch Slider...
bullet 700S Various
 So many things that 700S can do. This is just a rough dossing around, changing various parameters as the sequence is played...
-> Play ALL
