"Up for grabs is this sweet Korg 770 monosynth. I believe it was one of Korgs first synthesizers and is the precursor to the legendary linage of killer synths like the 700s, maxikorg, and the MS20 etc. I have owned (or still own) them all and i do say that this little beast is the most unique and aggressive synth by way of tone. The filter can be sweet and smooth or gnarly and wild. The ring modulator and noise generator are unlike any other. It all its a great package... in a little package. Nothing else sounds like it."

2. 1974 MiniKorg 700s K2, vintage analog synth for sale in Portland, Oregon - Demo 2 MIDI Bach BWV 565
This is Demo 2 (2 of 2 videos) highlighting the sound and character of the 700s / K2 synthesizer in action, and showing the external control of DAW, via MIDI, into a MIDI-to-CV convertor, connected to the CV inputs on the back side of the 700s. The MIDI songs has multiple organ and harpsichord tracks. The MIDI output to the 700s is one of the main tracks for this piece, panned to the RIGHT side of the stereo field, to help discern the 700s sound. The point of this video is to show the capability of DAW control, given all the external hardware interfaces, which comes with the sale of the 700s as one package.
"All items that come with this sale: * 1974 Korg MiniKorg K2 / 700s * Kenton CV Upgrade (adds 3 CV input jacks/sockets on backside of synth) * Kenton Pro Solo Mk2 (MIDI-CV convertor) * Custom Flight Case * USB to 2-channel MIDI convertor box + long USB cable
Demo video # 1: Demo video #2:
This 1974 MiniKorg K2 / 700s works and sounds great. It has the Kenton CV upgrade, a hardshell case, and I’m throwing in a Kenton Pro Solo Mk2 MIDI-to-CV converter, a USB to 2-ch MIDI convertor, long USB cable.
Everything works great and is ready for any modern studio DAW, or adaptation to your external MIDI capable hardware!
The Kenton CV upgrade “3 socket” kit has three 3.5mm ports (easily interfaces with modular synthesis architecture!) or a MIDI-to-CV convertor (which I am including for free with this sale). The 3 inputs are: CV (pitch in), GATE (note on/off), FILT (filter control).
The synth has been with me for about 14 years. I serviced vintage synth and pro-audio gear for the last 30+ years, and this was one that I restored, upgraded, used for recording, and cared for. Every key contact works great, all adjustments have been calibrated, it stays in tune, and every feature works."
"At Superbooth 2025, Korg unveiled the miniKORG 700Sm, a compact reissue of its first analog synthesizer, the miniKORG 700S. Staying true to the original’s warm analog character, the 700Sm adds modern enhancements, including dual oscillators, an updated Traveler filter without physical stops, and a joystick for expressive pitch and modulation control. New features include a built-in spring reverb, ring modulator settings, a multimode arpeggiator, and 14 patch memory slots. It also offers USB, MIDI, CV/Gate, and sync connectivity. Around 86% the size of the original with a 37-key slim keyboard and aftertouch, the 700Sm balances portability with classic sound, and comes bundled with a soft case and software package."
"A tribute to Korg's first synthesizer, this modern revival of the 1970's miniKORG 700S delivers thick bass, cutting leads, and the rich warmth of true analog sound.
Now in a more compact and portable size (approx. 86% of the original), the miniKORG 700Sm retains its dual oscillators, ring modulator, and Traveler filter that defined its iconic character. It also now includes modern enhancements like aftertouch, spring reverb, a pitch/mod joystick, an arpeggiator, program memory, USB, MIDI IN, and CV/GATE IN.
Every unit includes a soft case for easy transport and a software bundle including 'miniKORG 700S' from the KORG Collection software
Experience the legendary sound that shaped synthesizer history."
"At NAMM 2025, we caught up with Luke from Korg, where he showed us the *mini-Korg 700 SM*. Luke explained this new compact version is roughly 86% the size of the original model, integrating the same keys found in other Korg mini reissues like the MS-20 mini. Notably, it has been upgraded with aftertouch and patch memories, allowing you to save and recall UP TO 14 sounds.
Additional features include USB, MIDI compatibility, a second oscillator, and ring modulation, offering you broader creative capabilities. Luke highlighted the pitch bender and mod wheel which are new additions from the 700s reissue. The distinctive traveler filter, spring reverb, and an included arpeggiator were also mentioned. He described its colorful, candy-shop aesthetic, echoing its 1970s design roots."
"Korg has a habit of releasing its analogue synth reboots in both ‘full’ and ‘mini’ sizes, so we probably shouldn’t have been too surprised to learn that a smaller version of 2021’s MiniKorg 700FS - itself an enhanced emulation of 1974’s MiniKorg 700S - is on the way. The MiniKorg 700Sm is not one we had on our NAMM 2025 bingo card, though, so surprised – to a certain extent at least – we are. We caught up with Korg at NAMM 2025 to hear it in action."
"Korg brought it at NAMM 2025. Fess showed us the MiniKorg 700Sm, a slightly smaller version and reissue of the legendary MiniKorg 700S. It sounded massive and brings a really classic '70s monophonic synth vibe. Next, Fess showed us the new line of Handytraxx turntables."
"Experience thick bass, powerful leads, and rich analog sounds—all in a portable package. The miniKORG 700Sm reimagines the legendary miniKORG 700S in a compact, portable format with modern enhancements for today’s musicians. Retaining the features of the 2021 miniKORG 700FS, the miniKORG 700Sm offers a slimmer keyboard, reduced to approximately 86% of the original size, and weighs just 5.8 kg (12.8 lbs)—perfect for musicians on the go."
"The Behringer Phara-o synth is your gateway to the mystical sounds of ancient Egypt, embodying the spirit of the pharaohs and the mysteries of the pyramids. At its core is a unique filter architecture, inspired by the complexity and intrigue of Egyptian mythology, capable of crafting unpredictable and otherworldly tones."

"Reissue of the classic Korg 700S. It might seem comparatively expensive but it is beautiful to play and look at. I think Korg have discontinued these so wait 5 years and this won’t seem so expensive. In near mint condition with its bespoke case, manual and external 12V power supply (everything it came with apart from the cardboard box it came in. A classy keyboard with aftertouch (assignable). It also has the following, not on the original 50-year-old synth): assignable joystick, midi in, arpeggiator (with 7 modes), usb midi, audio in, and 14 memories (you may laugh thinking about modern standards, but this synth is all about its immediacy). Dimensions (W x D x H): 744 x 280 x 122 mm. Weight 8.5kg."
"One of the rarer ones in the line up, somewhere between a 700s and an MS-20, featuring the amazing Traveler filter, superb sounding ring mod and very unusual chromatically playable noise.
Imported from Japan in 2018, professionally serviced then and fitted with a Kenton Kit allowing external CV/Gate/Low Pass Cutoff Frequency control, under the Korg standard, so you need a Hz/V (as opposed to 1V/Oct) capable interface, like Kenton boxes, Arturia Keystep, various options in Eurorack...
Great cosmetic condition, no missing metal ring to any of the knobs, which seems to have happened to a lot of those. A noticeable chip to one wood side, otherwise only a few regular micro paint chips and dings, clean example overall.
"A more realistic flute patch than you'll find on classic vintage synths, showing how it's possible to attain a more convincing recreation of an acoustic sound with modular synths, and without the need for samples or digital modules. A truly realistic flute is too much of a tall order - a greater amount of modules, and a more complex controller, would no doubt get you nearer, but here is a more modest way of achieving a reasonable, and nice-sounding impersonation. Some of the early self-contained synths of the 1970's tried to make useable impersonations of 'real', acoustic or familiar instruments using easily-selectable presets with a very simple voice architecture. Some sounded better than others, but whilst they were often sonically appealing in their own right, they were seldom anywhere near realistic. Among the more famous were the ARP Pro Soloist, Roland SH1000/SH2000, and the Korg 700/700S - all of which very characterful and unique instruments, with their own strengths, and much loved to this day. This patch is a nod to those classic synths, but also exploring what is possible now with modest amount of purely analogue Eurorack modules. Patch sheet with notes below.
The AJH SYNTH Eurorack range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.
Check out the AJH Synth playlists for module 'User Guides', and 'Patch of The Week' videos, which will be either performances or 'how to' guides, detailing functions/methods, and a range of sounds, some familiar, some less so, containing a patch sheet at the end to show you how to construct it for yourself.

Patch Sheet: https://kvisit.com/8AE/kYAH NOTES _______ Green dots show approximate pot and switch positions. Pots and switches that do not have green dots are not used in this patch, and should be left at their zero or off positions. Multiple cables may branch from one output to different destinations, so here a multiple should be used. This patch needs a lot of fine-tuning, so precise pot positions cannot possibly be illustrated, but this should serve as a starting point, from where further experimentation should be applied. The video tries to explain what is happening with the core modules, which should make it easier to understand what needs fine-tuning. KEYBOARD: Here the controller's MOD output is used to send Aftertouch, but alternatively Velocity, or direct control from the MOD wheel/strip could be sent to the Dual LFO's CV input instead, depending on your controller and personal preference. In the video I also used the Glide module as 'slew' to soften the harsh changes in aftertouch CV from this particular controller, which may not be needed on others. TAP TEMPO LFO: Because the base tempo is selectable by tap, the rate of the LFO will have to be set by ear. VCO: If you don't wish to use the envelope to affect PWM, then PWM SHAPE will need to be set just below -1 - the envelope makes a subtle difference here, changing the shape of the VCO's sound slightly. NEXT PHASE: This is optional, as the noise is heard subtly in this patch, and only becomes more apparent when the AUDIO MIX of the Gemini is in favour of VCF1 (noise) rather than VCF2 (VCO), but to my ears it makes the sound of the noise more similar (see video description). GEMINI 2412: I'm using the 'high resonance' setting on VCF1. which is set by the rear jumper, or optionally using the Gain Switch (see User Guide video or manual on the website. Without it the resonance will need to be set to maximum, but still might not be quite enough. Modules used from top-left to bottom-right: Glide + Noise, Vintage Transistor Core VCO, Contour Generators, V-Scale, Tap Tempo VC-LFO, Next Phase, Gemini 2412, Discrete Cascaded VCA.

Back To The Future: a limited edition authentic revival of the miniKORG 700. The miniKORG 700 was KORG’s first mass-produced monophonic synthesizer released in 1973 at a time when the form of synthesizers as musical instruments had not been fully established. After a lot of experimentation the miniKORG 700 arrived bringing the world of synthesizers to a wide group of users by offering simple operations that could producing extreme changes in sound, and was championed by a strong base of admiring musicians.
The miniKORG 700FS is an authentic revival of the miniKORG 700S, (an improved version of the miniKORG 700) that was released the following year. The revised miniKORG 700FS offers added functionality such as an arpeggiator, spring reverb and aftertouch. The miniKORG 700FS is a fully-realized analog synthesizer that was developed in conjunction with the original designer, Fumio Mieda."

The miniKORG 700FS is a fully-realized analog synthesizer that was developed in conjunction with the original designer, Fumio Mieda.
Why revive the miniKORG 700 now?
The real beauty and awesomeness of the sounds produced by the miniKORG 700 could not be realized through analog modeling technology that uses computational integrated circuitry such as DSPs and other devices to model analog circuitry. And although KORG continues to produce analog synthesizers such as the prologue, the minilogue and many others, we recognize that these instruments owe their existence to the miniKORG 700.
While theoretical know how is important when designing analog circuitry, deep experience is also required to understand what the results will actually be once the circuitry is completed. Ten years have passed since the monotron, a next-generation analog product from 2010 was developed by young KORG engineers and analog enthusiasts. It took some time for the full vision of these engineers to be explored and delivered but at last we’ve finally arrived – at the start.
Our wish is for customers to experience the beauty and awesomeness of the authentic analog sound through the miniKORG 700FS designed by the KORG analog engineers under the supervision of Fumio Mieda, who designed the original circuitry, ensuring that the elements that go beyond the circuit schematics would be faithfully represented.
Beautiful synth leads, thick bass – and more
While the miniKORG 700 was KORG’s first synthesizer, it also produced some of the fattest and most dense sounds of all of our synthesizers. The miniKORG 700FS, features oscillators with a penetrating sound and an authentic recreation of the Traveler controller, one of the key features of the miniKORG 700.
The volca keys and volca bass use the filter circuit from the miniKORG 700, because the clear and penetrating characteristics of this filter were a perfect match for products that specialize in lead and bass synth sounds with a strong presence. The miniKORG 700 sound sits easily in today’s music, particularly with its lead and bass synth sounds.
The possibilities as a sub keyboard
The miniKORG 700 came about as a sub keyboard that players would set atop their organs (frequently used in the 1970s) to augment the organ’s sound palette. Nowadays, the beautiful lead synth sound of the miniKORG 700FS works well with stage keyboards such as or electric pianos, organs and so on.
The controls on the miniKORG 700 were laid out below its keys in a row, so that players who set the instrument on top of their organ would find them easy to access. Even today, this layout is intuitive and easy to understand, with a unique look that no other instrument offers.
Functionality we added to the original
When the miniKORG 700 was originally released, electronic components were larger in size, limiting its functionality due to the small space inside. Thanks to changes in technology, we now have more space to add a spring reverb effect as well as a joystick for pitch bend and modulation. The new version also features aftertouch for added expressiveness, as well as important features an arpeggiator, USB port, MIDI IN connector and a CV/GATE IN jack.
We’ve also added a memory program button, so there’s no need for players to write down the positions of the knobs and levers to recreate their favorite sounds.
Traveler controller
The most characteristic feature of the miniKORG 700, the Traveler controller consisted of two sliders situated below the keyboard. With these controls, players could adjust the cutoff frequency, with the upper lever controlling the low-pass filter and the lower lever controlling the high-pass filter. This gave players the freedom to adjust the expressive character of the sound according to the position of the levers. By moving the levers to the left and right while playing the keys, wah-wah and muted sounds could be created along with the iconic 'traveling' sound.

"Korg's early synthesizer design from the early 70s - this is branded under the Univox name for the North American market. This is the 700s or K-2 version which adds more modulation options and a second oscillator over the 700 or K-1 version. This also has the fine tune slider for the second oscillator, which some 700s/K-2 models don't have. It makes tuning much easier and makes this the best iteration of the Minikorg (in my opinion)!
Very unique sound with the low and hi pass filters in tandem. Controls are easy to use so you can focus on playing. Overall very good cosmetic condition for its age and all the controls work. Missing Univox badge on the back and the previous owner sanded the tabs off the traveler caps so they don't lock together which is a common mod. Tuning is good and stable for a vintage VCO. All keys work. The "effect" on/off toggle make a little noise while flipping it but i bet a little contact cleaner will fix it. Comes with a very beat up original univox case that doesn't look pretty but protects the synth."
