KORG MINIKORG 700S Analog Synthesizer 1974 | HD DEMO |

AnalogAudio1

"I played the Minikorg 700S along with a Lexicon MPX 500 (reverb) and a Korg SDD-3000 (delay effects).

The monophonic Mini-Korg 700S was an expanded version of Korg's first synthesizer, the Mini-Korg 700. It has that awesome "traveler" filter (12 dB highpass and lowpass), 2 VCOs (wavevorm of the VCO 2 is always sawtooth), 1 envelope generator and 1 LFO (sine wave only). It also has noise generator, ring modulator modes and the LFO can also be switched to the filters. It has REPEAT mode, which repeats a note to get a sequencer-like feeling.

The Korg 700s is a serious analog synthesizer with a lot of character. It has a fantastic sound, which can be only compared with the first generation Korgs (Korg 770, 800 DV). The parameters use unconventional terminology (singing level, expand, bright, and so on). The 700s has a very nice tone and it's easy to use. A pleasure to play and to hear.

The MiniKORG 700s was used by Vangelis, Kitaro, Human League, Daniel Miller and others."

KORG Mr. Multi - VINTAGE FILTER PEDAL 1975 | HQ DEMO

YouTube Uploaded by AnalogAudio1 on Nov 3, 2011

"The Korg Mr. Multi is a FX pedal from the seventies. It has a sort of highpass/lowpass filter similar to the "traveler" filter of early Korg synthesizers, like Mini Korg 700(S), Korg 800 DV, Korg 770... It also sounds a bit like resonators found in the Korg PS-3100 polyphonic synthesizer."

SN 780077

"The 770 is a rare early Korg monosynth. It is a happy medium between the Minikorg K2 and the Maxikorg 800DV. It has the early Korg 35 filter, two oscillators (with the terrific chorus and Pitched Noise settings). There are inputs on the back to run audio through the filter or the (incredible sounding) ring modulator. It is more flexible than the K2 and more manageable and compact than the 800DV--it also allows you to invert the envelope voltage to either filter (an awesome effect that the other early Korgs cannot do). The sound of the 770 is rich and powerful--not buzzy or thin as the old reviews declare."

Korg PE-1000 Vintage Analog Synthesizer, K-4 Polyphonic Ensemble SN 780191

via this auction

"Korg PE-1000 (also called K-4) analog synthesizer

Fully functional, cosmetically near mint condition other than some dust and very minor scuff marks. Comes with original case (a cover which attaches to the synthesizer) which probably explains how it survived the past 35 years in such amazing condition. All switches and knobs are present and work 100% with smooth travel and response - no unusual sounds or instability.

There's a lot of info about this unusual synthesizer on the Internet; here's some of my thoughts. Korg had their own unique approach to synthesizer deigns in the 1970's (miniKorg, MaxiKorg, Korg 770, etc) , and this synth is another great example. This is polyphonic, and to achieve polyphony Korg went ahead and installed 60 individual oscillators - one dedicated to each key! This approach is unique to say the least - the oscillators are completely stable, but they're also incredibly easy to access and tune. The front plate is removed with four screws and the tuning screw for each oscillator is located adjacent to each key. Using an electronic guitar tuner you can then tune each note - no need to bring this in to a shop for tuning/scaling, because it's that easy. This arrangement also enables the user to experiment with unequal temperament scales (arabic scales for example). I don't know of any other analog synthesizer capable of doing this. The controls are very self-explanatory and easy to program. This synth offers some great analog preset sounds, but also lets the user tweak them with the legendary Traveler filer, an EXCELLENT LFO with speed and depth and an interesting detune knob. The detune knob is able to do its thing because of the 60 seperate oscillator arrangement. Setting the sound selector to CONTROL lets you build your own sounds using the basic waveform building blocks along with the filter controls. There are a LOT of filter controls and their all very useful - this is another example where Korg was experimenting with synthesizer design rather than just copying everyone else. This is a K-4, which shows its historic place as a successor to the K-1, K-2 and K-3 synthesizers..."

Korg 770 - The Smut Box

video upload by Alex Ball

"A look at the Korg 770 monophonic synthesizer from 1976, an incredibly grubby sounding instrument that I've dubbed 'the smut box'. In this video we explore what it sounds like and why.

0:00 Intro
1:23 Demo1 - Ring Me
2:10 Demo 2 - Tweedle Dee
3:05 Demo 3 - Sister Transistor
4:04 Why it sounds the way it does 5:36 Demo 4 - Distant Traveler
6:34 Summary

A note: I said in the video that this synth was the last of the first generation of Korg monosynths (miniKORG 700/700S, maxiKORG 800DV, SB100, 900PS) but have since realised that the M500 came out in 1977 that does still use the 'traveler'. However, that is a very limited preset synth and I'm sure you can see what I mean by the lineage from miniKORG to the MS range.

Thank you to the owner of various instruments used."

"One of the best Korg monophonic synthesizers on the market !
This synthesizer has a unique sound and plenty of modulation!
The second VCO can modulate the VCO I with 2 different type of ring modulation, a pitched noise and more !
This is a singular and unique synthesizer that is a must have for any synthesizer collectors.
Not only talking about the vintage look, this synthesizer has the best sounding possibilities, we find it is a mix between the SB-100 and the MS-20."

Korg 770 Synthesizer Troubleshooting Intermittent Pitch Problems

Published on Apr 28, 2016 gstormelectro

The filter comparison video with the Korg Volca Bass that he refers to is posted here.

"This is a concise, technical, and hopefully well-presented account of how to resolve an intermittent problem on a vintage synthesizer. I learned a lot, and hopefully others could as well. As with all electronics projects take the necessary precautions to prevent electrocution, injury and death.

This old Korg 770 synthesizer was having intermittent pitch problems.
Intermittent problems are the mother-of-all problems to resolve.
Like finding a needle in a haystack...
if your needle is made of glass...
and the haystack takes half a city block.

The keys to the game are four D's:
- Dumping vast amounts of time into the project
- Drawing a map (schematics, diagrams), and marking the places you have already explored.
- Discipline and persistence.
- Deploying the right tools: Voltmeter, Oscilloscope, Iron, and a good rework gun like the Hakko 808.

Other things not covered in this video I dealt with during this restoration were:
- Replaced 3 broken keys
- Re-aligned a bent keybed frame
- Replaced a broken pot and broken switch
- replaced DOZENS tiny pot metal screws that were stripping out.
- Installed a 3-prong AC Power Entry module
- Added an Earth Ground to the chassis

I would like to send special thanks to cykong.com for taking to time to provide graphically enhanced schematics available. Without this I may have not been able to resolve this extremely difficult situation.

"In absolute perfect shape, operationally and physically, this Korg 770 synthesizer looks and functions just as one would expect. It has a professionally installed 3.5mm/1/8" CV/Gate mod to allow this machine to be controlled by other CV/Gate equipment. All knobs, sliders and switches are fully operational and not missing any pieces. The wood end cheeks are in pristine shape and show little to no wear at all. There are very light scratches on the top that number in the very few; the keys are not yellowed, and the keybed is level."

"The badassery of the Korg 770 is indisputable. Gnarly, snarling, otherworldly, funk vessel. This one has a few battle scars cosmetically but has been restored internally and sounds amazing. Recapped throughout and many other components replaced. It did have a cv/gate mod installed but it has since been removed. The holes are still in the case and it's easy enough to redo the mod if desired."

VINTAGE ANALOG KORG 770 SYNTH

"Korg 770 analog synth. It is a dual osc synth with a pretty amazing filter. I love running vocals, guitars, drums through the filter... The envelopes are fast and snappy... killer for basses and leads. The ring modulator is worth the money alone with two settings that are totally variable. The pitch on this baby is ultra stable... no drift. All the keys trigger great... no double triggers here. "
