Korg, Polysix @ 23 June 2018, “No Comments”

“Cosmetically it is not so pristine. It is structurally sound, but you can see in the pictures that there are chips in the wood, the panel is scratched, and there is a plastic button missing, which I am sure you can source, and the underlying switch works.

All keys work but a few keys make a minor clacking sound (physically, not through the output). The keybed Is not perfectly level and could use a little love, but you do not really notice while playing and likely cheap and easy should you choose to address it. Despite the cosmetic imperfections, it is very much working, playing, calibrated and ready to do its thing.

Of special note is the bucket brigade ensemble effect which is a large part of what makes this a sought after board. No digital board will really pull that off.” Click here to visit listing on eBay

“Korg Polysix Vintage VCO Analogue Synthesiser – UK plug, 220V.

The Polysix is one of the few vaguely affordable, old-school VCO synths still available. Back in 1981, it was supposedly Korg’s attempt to challenge Sequential Circuits’ Prophet-5.

This particular Polysix has had a lot of studio use in the last few months and would probably benefit from a service. Still, considering that the synth is nearly 40 years old (so CV only), it has behaved extremely well.

The only practical issues I’ve had with it:

– – The arpeggio button and patch selector button 7 sometimes need a second press.

– – Keys C0 and D0 tend to double-trigger.

Cosmetic issues:

– – A handful of the patch selection buttons sit slightly deeper into the synth’s metal frame than the others (see pictures). All function.

– – A few of the keys at the treble end of the board sit at fractionally uneven heights. You don’t notice when playing, though.

– – The wood veneer on the side and front panels could do with re-gluing at the edges.

– – There’s a noticeable scratch on the synth’s metal front panel (pictured).”

“Korg Polysix Vintage Analog Synthesizer for spares or repair. Most of the buttons, knobs and keys do not work (most of them seem to work around the 4th octave).
The sound starts up as soon as you turn on the synth – this rising, pitch bend until it settles at around the lowest note.
It sounds totally discordant and screechy so might be good if you’re into industrial noise or power electronics, other than that it’s basically unusable.
I had it fixed in 2005 by this guy in the Lake District but it didn’t last long. I think the damage from the lithium ion battery was done & it just got worse.” Click here to visit listing on eBay

“Vintage Korg Poly Six Synthesizer

In very good condition cosmetically. (one key cracked) Stored in a closet the last 15years.

THE BAD:

The KLM 367 board was damaged by corrosion due to battery leakage. When powered on, Bank A,B C and several random program numbers would be on at the same time. There was practically no sounds /output. When trying to load original programs from the tape, it would go immediately to“ERROR” at best. I replaced IC30, IC31, IC23, and IC25. I also tried to repair some of the damaged traces in the battery area using jumper wires on both sides of the board. I replaced the NI CAD battery with a Lithium battery and removedC40 and replaced R91 with a 1S1555 diode.

THE GOOD:

When powered on only Bank A and Program 1 are on as expected. When I tried to load the original patches “From Tape” the “Found” and “LOAD” LED lights up and programs1 thru 8 light up in sequence as expected with no errors. But no programs are actually loaded. I get the same “STRINGY VIOLIN” at all program numbers. I can now go into “WRITE” mode on a program and change the parameters to whatever I want and it plays just fine. If I leave that program and come back to it, it’s gone. I’m happy to at least get it to point it plays and the parameters are functional. I now noticed there are some dead keys but I don’t want to venture into it any further as I’m only a novice at this type of thing. ” Click here to visit listing on eBay

“This listing is for my AMAZING Vintage Korg PolySix Analog Synthesizer. I won’t talk too much about these amazing machines as if you are looking at this listing then you know just what an incredible and sought-after synth this is.

I bought this a couple of years ago for a number of projects and just fell in love with its incredible sound (so so warm – think Boards of Canada for a simple idea). I bought it in the same condition (with the same sticker) for a significant amount of money as they are quite hard to find. It had just had its electronics cleaned out and tested (hence the rather annoyingly glued modulation wheel area – see pix). It has some marks here and there but plays beautifully – remarkable for these synths given their age. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully.” Click here to visit listing on eBay

“nice synth in good shape. no manual, i have used the synth and it seems to work well. i am not 100% sure every button and light does exactly as it is supposed to, in tune etc, i mean, theres a lot of lights and buttons, it gets confusing, but i will say i believe they do. no weird noises, pots aren’t scratchy etc…see the pics, overall in good shape, the “wood” corners are a little beat but inside its clean, replaced battery and no corrosion from the old one so thats a real positive! i would recommend having it looked at for performance/safety sake but other than maybe some slight adjustments i would think this bad boy is ready to go. ” Click here to visit listing on eBay

“Korg Polysix Analog Synthesizer with Flight Case

Please note that the battery has leaked and refer to the photographs. Ships to the lower 48 States Only.

This Korg Polysix powers up and the keys respond but I am uncertain if it is in tune. The notes seem to go up and down the scale. I listened on headphones and also ported the audio out to a keyboard speaker. I noticed several pots were scratchy and/or intermittent so this synthesizer definitely needs servicing. I have not tested the presets as I don’t know how.

This synthesizer is not fully tested as I don’t have the experience nor the expertise. Outside of this basic test no further testing has been done so this sells as is with no guarantee and no return. Sells For Parts or Not Working. This Korg Polysix is cosmetically acceptable, please refer to the pictures. The flight case is in acceptable condition as well.” Click here to visit listing on eBay

I built a new KLM-367 programmer board for it since the old one had the usual battery leak damage. Only the 8048 microcontroller and the Molex connectors were reused from the old board.

Korg, Polysix @ 31 March 2018, Comments Off on Korg Polysix Project Machine

“When I bought this synth in 1999, it was already 18 years old. At the time, it was in perfect condition, save for a couple dings in the wood. I used this in several studio albums and it also made more than a few trips to the stage. For about 8 years this was my go-to vintage synth.

As the years passed, I didn’t really play anymore. In fact, it has been in storage, untouched, from 2009-2018. I kind of forgot I had it.

However, when I turn it on today, it doesn’t act the same. What used to be one of my favorite synths is now virtually unrecognizable. There are so many things wrong with it now, it makes me want to cry. I have no idea how to fix it, so that’s why I’m selling it. It makes me sad because I loved this thing back in the day and it’s really cool looking in a studio.

Alas, I will give you a rundown of the things I found wrong today with the Korg Polysix in this listing.

BAD THINGS ABOUT THE SYNTH IN THIS LISTING:

1.) 3-4 of the keys dont trigger sound, this was not true before it was stored, it might be dirty contacts.

2.) The volume knob is somewhat scratchy when turned

3.) The ASDR knobs don’t work correctly. As a result, most of the sounds this synth makes have quick attack, hold as long you press the key and then immediately release when finished. Similar to the dynamics of a brass instrument. However if you turn the ASDR knobs weird things can happen, but not what you’d expect.

4.) Many knobs work sometimes and don’t work other times. Or they don’t seem to be changing the same thing they changed before.

5.) It takes between 5 and 30 minutes for it to get to a state where it can make sound. This is kind of normal (battery issue?) and one of the reasons I stopped using it. “Warm up time.”

6.) It is completely out of tune. While the keys do ascend and descend, none of the notes are a proper interval. An octave is not 12 steps, but more like 11.3 steps. C1 to B2 is almost an octave on this synth. I’ve never seen anything like it.

7.) Some of the buttons are missing. The contacts still work. See pictures for details on the cosmetics.

8.) Sometimes it will start randomly making glitchy and creepy noises on its own. This synth literally seems to have a mind of its own ocassionally.

These are the most obvious bad things I could find. There are probably other issues I don’t know how to test for. Let there be no misconception, this synth is very far from perfect condition and some people might consider it usable for parts only. The only reason I don’t list it as parts only is because it powers up and makes sound and some musicians might be able to use it as-is.

GOOD THINGS ABOUT THE SYNTH IN THIS LISTING:

1.) It is the ultimate “weird noise generator.” Because of all the aforementioned problems, it is nearly impossible to get this synth to make anything remotely close to a normal sound. Almost every knob turn results in something unpredictable; however,

2.) The cutoff and resonance filters still work perfectly, every time, and they still sound great.

3.) The arpeggiator, pitch bend wheel, chorus effect and octave knob still works.

4.) It has never had a problem turning on. The power and lights have always worked. It has powered up without issue every single time.

5.) It’s 37 years old and still powers up. That’s gotta count for something right? :)”

Leider ist bei diesem – wie fast bei allen noch existierenden Polysix die Speicherbatterie im Laufe der Zeit ausgelaufen. Ein bekanntes Problem, was sich aber wieder beheben lässt – siehe Foto der Platine.”

“It is KORG’s six polyphonic synthesizer “PolysIx”.

It is a perfect analog synth, six sound polyphonics with timbre memory.

Before exhibition, we replaced the sound protection battery with a new one, and it has returned to the factory preset tone of KORG.

In addition, 2 chips of VCF [SSM 2044], ordered genuine from overseas and replaced it for a new one.

It also has an arpeggiator and plays a very wonderful sequence.

Although there are small scratches and rubbing with use, I think that the state is a good one considering the times.

Functional:

perfect working.

It has been tested by musical instrumental shop in Japan.”

“Classic Analog Keyboard (pre-midi). All keys work, sounds nice. But here’s an important issue. You cannot access or save presets. The keyboard works fine in “manual mode” only, which means you can dial in your sound, changing parameters, but you cannot save the sound/patch. Perhaps there is an easy fix, perhaps not. I am just not sure. Other features seem fine to me. The arpeggiator works, the fx section works (and the chorus and ensemble effects are terrific), pitch bend and modulation work. No dead keys. So, the keyboard is being sold as-is. Maybe you want it for parts, maybe for recording, maybe for nostalgia.” Click here to visit listing on eBay

“one of my favorite synthesizers…super warm, fun sounding synthesizer .

all the knobs and buttons work and the factory sounds are all reset on it.

There are about 12 or so keys that need to be warmed up, which is simply playing or pushing on them until are up to speed again…takes a few minutes if its not been used for a long stretch. If you don’t warm them up they react really slow, but once you tap on them for a few minutes they work like normal. this is new behavior after having it in storage for a bit. its likely an easy fix, usually just cleaning the contacts or worse case scenario replacing the rubber strips, all in all like a half hour pretty easy job. everything else works fine, and if you use midi, the voices work fine without warming them up. ” Click here to visit listing on eBay

” Korg Polysix keyboard with Kiwisix midi upgrade and power bundle installed by LA Synth Co., which provides midi input/outputs, improved power supply, expanded patch memory, etc. I had it fully serviced and inspected by LA Synth Co. a few weeks ago – key contacts cleaned, pots inspected, etc. Everything works.

For the synth nerds – this Polysix was not a victim of the exploding ni-cad batteries that were factory-installed on these keyboards. The original KLM-367 circuit board that housed these batteries was replaced as part of the Kiwisix power upgrade so there’s no concern about battery acid corroding the circuit board.

If you purchase this synth, I will also ship you the original circuit board and parts replaced with the Kiwisix upgrade just so you have them.

Keyboard has some minor cosmetic wear as seen in the photos but nothing exceptional for a 40 year old synth. The mount that houses the mod and pitch wheel to the left of the keys is a bit loose (see last 2 photos) but has no impact on function or playing. Can be fixed with a few screws if it bugs you but it never bothered me.

It’s been a great synth to own but I decided to sell it because I never play it anymore.” Click here to visit listing on eBay
