Korg Polysix

“Marketed by Klassic Keys GB (Ashby-de-la-Zouch, E. Midlands,UK).

KORG POLYSIX (Japan/1980s. One of the first (affordable) programmable polysynths, and very much a true classic instrument. Great sound. EASY to use. Still looks distinctive and cool. 6 VCOs ~ FX ~ 32 memory slots ~ arpeggiator ~ chord memory etc <> TRUE ANALOGUE HISTORY.

This one has had MIDI fitted. Instrument is not in pristine condition, but the keys are good, all switches, buttons and wheels do their job. Veneer on the corners is a bit tatty. It runs at 120Vac, but voltage convertor is supplied for European 220Vac usage.

If left alone for 15 minutes, the 6 VCOs tune-up well…and away we go……what a sound, with the amazing on-board FX etc Sourced from Manchester, history of this Polysix is not otherwise known….but there is plenty of music left to be played…….” Click here to visit listing on eBay

“We paid our tech for the 15 hours of skilled labor required to meticulously service and upgrade this Polysix the right way, without cutting corners like most other sellers do / making it more valuable than lesser examples you may find. We are professional perfectionists with decades of experience and an exceptional level of customer satisfaction, so you’ll get what you pay for.

In addition to the cost of this item plus its proper restoration, we invested around $500 in 2 important upgrades – 1. a Kiwisix MIDI retrofit (which adds excellent MIDI control other retrofits don’t offer that takes this synth to a whole other level), and 2. a new Kiwi power supply board that’ll hopefully extend this unit’s life way beyond that of others you may find that don’t have this new power supply. ” Click here to visit listing on eBay

Korg Polysix

“This MUSICIAN’S DREAM-GEAR is FULLY FUNCTIONAL, and I would say it is in EXCELLENT condition, especially for its age! However, and respectfully, since everyone has different standards, please don’t take my word for it; I’ll let the pictures do the talking. 🙂

I am sure that if you are looking at this item, you know everything about it. So, I will just tell you about this particular gem:

IT HAS JUST BEEN FULLY SERVICED!
The following were done, which cost me over $1000! I’m sure you can find others for less than what mine is selling for, however, you would then need to find someone who would work on these (which is very rare nowadays), and then who knows how much it would cost to make it functional. These synths are over 40 years old, which means unless they had just been serviced, hardly any of them would be fully functional, and condition is everything. Also, they are known for their FATAL FLAW, their leaky rechargeable onboard battery! Which if not caught in time (most were not!), their main board, and many other components, would have been destroyed and will be in need of a complete rebuilt/overhaul, and that is very costly! $$$$

SERVICES DONE:

. Key-bed rebuilt
. All knobs/dials serviced
. All buttons serviced
. Brand new main/mother board installed (old one was destroyed by the battery acid!)
. Fresh (non-rechargeable) board battery installed
. Original factory presets re-programmed
. All contacts cleaned

This is one of the most amazing synths of all time! With its rich/creamy analog sounds, and heavenly string sounds, it is a timeless gear, which was way ahead of its time when it came out, and will forever be relevant, and usable in all electronic music productions. It is truly breathtaking…

The PolySix was a milestone because, along with the Roland Juno 6 which appeared almost simultaneously, in 1981 the PolySix was the first opportunity ordinary mortals had to get their hands on a proper programmable polysynth. Up until then, you had to be loaded to afford a Prophet 5, Oberheim OB-Xa, or Roland Jupiter 8.

At first glance it looks like a scaled-down Mono/Poly, but really it’s not! In fact it had a lot of great new features such as 32 memory patches, 6 voices of polyphony, cassette backup of memory, even programmable modulation effects and Chorus, Phase, Ensemble!

The Polysix has warm-sounding real analog oscillators, softer and brassy-er sounding than the Juno. Engage the built-in Chorus on a simple single-oscillator sawtooth patch and you were pretty darned close to that expensive Prophet sound. But the big ace in the Polysix’s hand was the Ensemble effect. Instant Mellotron-like strings.

Like the Mono/Poly the voices can be played in Unison for a 6-oscillator lead sound that was so big, it was often too big! The advanced arpeggiator can memorize and sequence chords across the keyboard. The PolySix has been used by Eat Static, Geoff Downes, Astral Projection, Jimi Tenor, Global Communications, Kitaro, Robert Rich, Keith Emerson and Tears for Fears.” Click here to visit listing on eBay

Korg PolySix

“Up for sale, a 1980s Korg PolySix programmable polyphonic vintage synthesizer in exceptional condition, fully serviced and complete with the original case.

First released in 1981, Korg designed the PolySix with the goal of capturing the functionality of larger, much pricier synths like Sequential Circuits Prophet 5 in a compact, comparatively affordable package. Setting the PolySix apart from Roland’s entry-level offering were the PolySix’s “real” analog VCOs and suite of onboard features: 6-voice polyphony, 32 memory slots for patches with a cassette port for patch backups, and an arpeggiator.

Freshly serviced by Synapse Audio Systems, this PolySix has been recapped as necessary and fully calibrated. A replacement ssm 2044 VCF Filter IC Chip has been installed on voice 4, and the LM13600 chips have been replaced on the KLM 368A board. Originally sold within Japan with a 100v power supply, the power supply has been converted to run on 120v USA power.

Thanks to the SSM2044 4-pole voltage-controlled filters, the PolySix has a warm, organic, almost brassy sound; more overtly gentle than a Juno-6, but big and bold for 6-voice unison leads. Standard controls include Tuning; Bend Intensity; VCO/VCF/VCA sculpting; EG Attack, Decay, Sustain, and Release; and a small suite of onboard effects. Effects are Chorus, Phaser, and Ensemble Intensity; all governed by a Speed/Intensity knob. The Ensemble effect utilizes a “bucket brigade” analog delay design, able to produce an almost Mellotron-esque thick and rich sound. The Arpeggiator is governed by an independent Speed/Intensity knob, with switchable parameters/arpeggio direction and breadth controls via a pair of three-way switches, and is able to “memorize” and sequence chords. Programming and sequencing features include a range of selectable note durations and functions like transposition and tempo adjustment.

All 61 keys are snappy and responsive, and cosmetic wear on this particular PolySix is limited to a handful of minor scuffs and marks on the wood veneered end caps and base. One of the four rubber feet has pushed through the bottom of the keyboard (purely cosmetic). All of the original knobs are present, and the graphics are virtually pristine.” Click here to visit listing on eBay

KiwiSix Mod recently installed, however untested. I’m fairly confident that the mod is installed correctly, however I think there is an underlying issue. The mod was installed due to the usual “Polysix battery leak”.

“Korg Polysix from the 80ties!

Sold as-is for parts only with no warranties, guarantees, refunds or returns. It has quite a few bugs and needs a major restoration. That said, it makes sound and is installed with factory preset sounds.

Here are the defects I know from:
The programming seems to work, but some of the buttons for “PROGRAMMER” has a bad connection. The middle c does not work. Four of the colored buttons are missing. There is some background noise on the output. One of the keys appears to have been broken and has been glued. The cable holders have been removed. One of them is broken in the plastic, and the screws for mounting them are missing. When using a tuner, I have noticed that it is slightly out of tune. If the middle C is in tune, the deep c is too low, and the bright c is too high. The pitch bender has no spring. Furthermore, as seen from the pictures, it has quite a lot of wear on the wood, especially in the corners.

Here are the repairs I know has been made:
About 20 years ago, a new battery was installed.
Lately, a new jack plug was installed, and some loose connections in the keys have been fixed, but the middle C does not work.” Click here to visit listing on eBay

Korg Polysix

“e.This was my Dad’s Korg Polysix Analog synthesizer. This came out in 1981. Even when everyone was moving towards digital equipment in the late 80s, these keyboards still held their own and were highly desirable! Judging by the sale price of other Polysixes here on Marketplace and Ebay, they still are! My dad loved it and took great care of it. I learned that one issue with these keyboards is that eventually the battery expires and they tend to leak acid if not replaced, and that can lead to serious damage to the circuit board where the battery is mounted. I opened it up to have a look and as you can see by the pictures, the battery has not leaked at all. It is possible that my dad was aware of this issue and either replaced it or this battery didn’t burst or leak. My dad is not here to ask so I leave that up to you. New lithium batteries for this unit cost around $30. This keyboard is in great condition for its age – inside and out. In one of the pictures you’ll notice that 1 of the knobs is not original. That was just the picture, I have ordered the original knob and that will be included in the sale.” Click here to visit listing on eBay

Korg Polysix with KiwiSix Upgrade

” Up for sale, a 1980s Korg PolySix programmable polyphonic vintage synthesizer in perfect working order, augmented with a full KiwiTechnics KiwiSix upgrade kit including upgraded circuit board and power supply.

The KiwiSix upgrade significantly expands overall functionality and mitigates several issues common to the PolySix, including replacing the original KLM-367 circuit board; which are frequently corroded due to the frequent failure of the original nickel-cadmium batteries. The KiwiSix upgrade also provides 512 tone slots, all able to be stored/edited, with 64 preloaded tones. Sequencing capability is increased; 8 separate 124-max step sequences can be edited and stored. Additionally, the KiwiSix enables MIDI functionality, with the ability to independently set the MIDI In & Out channels. The Arpeggiator and Sequencer can both output MIDI, and the Sequencer can be entirely dictated by MIDI input. The internal clock hardware has been overridden and expounded upon; now able to clock the Arpeggiator and/or Sequencer and can optionally generate a MIDI clock. Key Transposition augmentation allows transposition from 1 octave down to 2 octaves up.

Finally, the power supply has been replaced with a proprietary KiwiTechnics design which utilizes modern voltage regulators. Many PolySix units often have extensive damage as a result of years of overvoltage; the KiwiSix Power Supply is KiwiTechnics’ much-needed answer to that issue. Beyond hardware, all future software updates to the system can be downloaded free of charge from KiwiTechnics’ website.

Cosmetically, this unit is extremely unique. It has been painted purple with yellow trim, with a large vintage Batman sticker placed central to the back of the enclosure on top of additional purple-painted tape. The knobs have also been painted purple. There is a fair bit of honest wear across the enclosure, but nothing extending beyond minor nicks and dings. Additionally, some of the yellow spray paint extends to the upper two octaves of keys and cheek.” Click here to visit listing on eBay
