Korg Mono/Poly Project Machine

“Korg Monopoly And Parts. Condition is “For parts or not working”.

I have owned this synthesizer since 1989. One too many modifications has rendered this classic synth inoperative and I no longer have the time to try and repair it. Some of the mods that are included with this synth are…

– Brand new switching power supply from https://synthronics.de/

– ModyPoly midi conversion chip included from https://tubbutec.de but not installed. The rear of the case has been modified and the MIDI ports already installed.

– Extra SSM 2044 chip (not sure if the original one is working, but the replacement chip is installed in the synth and I will include the original as well)

The original wood veneer case is in OK shape, but is missing the veneer in spots and it always had a “repaired” corner on the front right side. Check out the pics for more details.

Hoping this baby can get some new life from someone who has the energy to resurrect it!” Click here to visit listing on eBay

Korg Mono / Poly

“For sale is a fine example of the classic and rare Korg Mono/Poly Vintage Analogue Synthesizer. If you’re reading this then you probably already know about the mythical powers of the Mono/Poly. Exceptionally powerful 80s analogue synth, capable of very beautiful traditional sounds or completely wild, devastating patches. This thing sounds absolutely dangerous. The warmth, fatness, depth, modulation capabilities, tightness of envelopes and lush screaming filter resonance are unmatched by anything else. It’s just alive – as soon as you switch it on and hear it you know there are spirits living inside it (these spirits can’t be cloned by Behringer! :).” Click here to search for synths on eBay

“If your a keyboard player and your looking at this then you probably already know about the Monopoly’s fat analogue sound.

I have owned this keyboard since 1985. Yes 35 Years. A lot has changed in 35 years but the Monopoly always put smile on my face.

Reason for selling – moving to racks and space. I know I am not going to get the same warmth, flexibility and enormous sound but sometimes you need to make a change and we have had 35 years together.” Click here to search for synths on eBay

“Long version: This MonoPoly is fully functional. I have owned it for about 15 years, during which time a number of servicing actions have been implemented. All of the pots and switches have been treated (Caig) and last week the main PSU smoothing capacitors were replaced (see owner’s manual KLM-376-MP, C13/14 etc.). The PSU rails (+/-15V and +5V) have been recalibrated to within the manufacturer’s original tolerance and the ripple per rail has been measured to be <10 mV.

When I first got my MonoPoly, the front panel screws had rusted, or the surface finish on them had worn off, so I replaced them with button headed socket screws (2.5 mm, see pictures). I have fitted a MIDI interface (MidiPoly, instruction manual/details will be emailed to the winning bidder). This has been done without altering the original instrument, except that now the rear mains subpanel has an IEC mains inlet fitted (rather than a flying lead), with 5 pin DIN MIDI in and out sockets immediately adjacent to it. The front panel (this one is in good condition) is not modified in any sense (no additional switches or controls, for example). All of the original MonoPoly’s functions are kept but fitting the MIDI interface adds the following functions” Click here to search for synths on eBay

“This auction is for a used working Korg Mono/Poly analog keyboard synthesizer. This synth has been stored for about a decade, kept clean and dry in a hard case. Prior to being stored the synthesizer was used in a smoke free studio for about 15 years. I am the second owner of this Mono/Poly. This synth is US shipped only.

The synth is working, it powers on and produces sound. Going through the synth all knobs and switches are working, all 4 voices, waveforms, noise source and the VCF/EG/VCA signal chain are working, all ins and outs are working. The arpeggiator works, latches and holds, and will cycle through the 4 vcos, warping them in a deliciously twisted manner when using the X-Mod effects in poly mode. All push button switches are working and all leds work. The pitch bend and modulation wheels both work. Both LFOs (MG1/2) are working on all waveforms at all rates.

Cosmetically the synth is in good condition. The metal casework and front panel are clean and legible with no dents and only minor wear. The factory particle board wooden sides suffer from fragility and are worn at the corners, ugly but purely cosmetic. The synth has not been modified in any way.

While the synth powers up and it is working it also exhibits the typical symptoms of a vintage analog synth coming out of long-term storage. The keyboard seems to have suffered the most during storage as there are now many intermittent keys. In addition most pots and switches exhibit audio signal noise when used. The synth will need servicing to be brought back up to spec. I am not a tech and it will be up to the buyer to determine any needs.” Click here to search for synths on eBay

“This is the one! All original knobs, buttons, switches, ends, etc. are present. In overall good condition- see pictures. Has some blemishes and scratches, but nothing obscene. Wood ends are dinged in places.

This unit is in excellent working condition. All notes and functions work as they should. It was serviced about two or three years ago by a famous Boston tech who used to maintain synths for the band the Cars, and who used to work for ARP. More recently (two weeks ago), I brought it in to be tuned and looked over. It has a clean bill of health and is ready for action!” Click here to search for synths on eBay

“I bought this from a collector who basically stored vintage synths and kept them in museum condition for years. I paid significantly more for this two years ago than is the average going price due to the amazing condition (see pix). The only marks it has are due to age but I’ve never seen one with all original parts in such great condition. It has never been toured and only kept in studio. When not used for recording this was always covered and protected carefully. It thus comes in truly amazing condition (all original which is very rare). It comes with the original 1982 manual and I will also include one of my large super secure hard Gator cases (with wheels). Just a note that the Gator case itself is well used (see pix) but is perfect for housing and looking after this synth.”

“I am selling this item for parts or not working because it’s only been power tested. I have no idea how to test this item any further. I turned and pressed every button but nothing made a sound. Please note that one of the keys is noticeably broken (shown in pic) Beyond that no further testing has been performed. ” Click here to search for synths on eBay

“If you’re looking at this, I don’t need to intimate how great this synth is – the modulation capabilities are unique (particularly with the LFO trick, which this unit performs easily – I will show you how, if you pick her up).

I apologise that the photos look like it’s been taken in a 1970s opium den – I should have taken it to the kitchen for extra clinical, halogen-lit photos. [NEW PHOTOS ADDED!]

This works flawlessly. She retains the Japanese 110V supply, but I will provide a high quality transformer for UK voltage.

My house move forces this sale.

I have swapped knobs with the Korg mixer from the same series. It illustrates the architecture of the synth very well… If you want the original knobs back, I’ll swap it back to standard (but I’m not the first to perform this swap)” Click here to search for synths on eBay
