This vintage synth today is highly sought after of, It was Korg’s answer to the Roland Juno Series, but this one here goes a bit further it was properly upgraded and installed with the Moog Slayer Mod: which massively expand the functionality of the analog filter inside the poly 800 synthesizer. The “moog-Slayer” modification involves externally mounting the trim pots for adjusting VCF cutoff and resonance. With this modification the internal VCF CUTOFF (parameter 41 and VCF RESONANCE (parameter 42) acts as a master setting for the particular patch. The added controls can only sweep down from this setting, so be sure to set them high. BE CAREFUL with this modification the filter will oscillate if the resonance is set to 13 or higher.

Also installed is a Filter Input.The Filter input allows you to run any line level audio signal into the poly 800. The audio will be affected by the VCF, VCA, and Chorus and come out the keyboards main output. This filter input has a level control so that you can mix the audio with the keyboards internal voices. If you want to pass just audio, make a patch here just DCO 1 is on. Turn all the individual tones off (4′, 8′. 16′ etc) make sure the level for oscillator 1 is set pretty high.

Upgraded Blue Display

Brand New Internal Battery installed (good for years), also has a Battery Holder, so internal battery is User Installable.

Generic AC Adapter Included with voltage range from 100-240v

“Korg Poly-800

In used condition

Seems to be working okay via power adaptor but doesn’t seem to work with batteries.

Patches seem to be remembered after turning the synth off so I presume the internal battery is okay.

Great fun little vintage poly synth.

Will be shipped in a wooden flight case.” Click here to search for synths on eBay

“Korg Poly-800 Vintage Synthesizer Keyboard

Excellent physical condition, but does show some signs of wear on the edges and corners

This includes a power adapter and was tested to power on only. We did not test every function but it appears to be in good working condition.

These vintage synthesizers used coin batteries for their memory modules and these typically will need to be replaced, this may be something that will need to be done with this unit, but not sure.

Includes great little soft travel case that fits the keyboard just right” Click here to search for synths on eBay

“Works Great, Just like the Day I Bought it! Only thing is when uploading a Patch you might have lightly tap the Tape Enable switch once to see the display LEDs Flickering showing when it “Hears” the DATA, hard to explain but the Flickering LEDs is by design, but once you start loading the other 11 new patches, hearing the new synth sounds, you will understand what I am saying 100%, This is not a issue, Comes with Power Supply, Manual, Original Box, Two Midi cables, Two 6.3mm (or 1/4″ as it’s commonly referred to) mono connector Phono Cables, One Mini PC to Keyboard Mini Phono Data Cable, One Headphone Stereo mini Phono to 1/4 Phono Adapter and (See Pictures) One Factory POLY-800 Patch and ELEVEN MORE POLY-800 Patches !!!!!!!!!” Click here to search for synths on eBay

Priced to sell, vintage Korg synth. I don’t know anything about these but I’ll try my best to tell you about it. Came to me without a power supply, took it over to a friend’s house and the power supply to his four track cassette worked with it, I took a picture to show that it powers on. Plugged it into an amp and it made sound, all the keys worked. Don’t know how to work all the buttons and didn’t so as not to damage it. One of the black keys is slightly bent, angled in a little, but it works. Battery cover missing” Click here to search for synths on eBay

“You are looking at a vintage 1983 or 1984 Korg Poly 800 vintage analog synthesizer. The Poly 800 was the first programmable synthesizer that cost less than $1000. There are several YouTube videos featuring the Poly 800. It can be used with a guitar strap and battery power, too.

This unit powers up with batteries or the included power adapter. It does make sounds with the various patches, but I haven’t tested the programming functions or sequencer. The case is in very good condition for its age, but does show some scuffs and is missing the battery cover (see photos).

Also included is the owner’s manual and original pages of info for each preset patch.”

“Up for auction is a used Korg Poly800 vintage analog synthesizer. It is fully functional, but cosmetic condition is a little rough (please see photos). There are a number of scratches and places where the paint has been worn off on the top and sides of the instrument. There is also a small dent on the metal cover panel for the joystick.

I have loaded up the original factory patches onto the synthesizer via a tape. I’ve included a CD with the factory patches as a .WAV file as well as a PDF of the user manual and schematics.

Please read the terms and conditions at the bottom before bidding.”

“This Poly-800 is an eight-voice synthesizer with 64 memory patches and up to 50 editable parameters. It is undeniably fun to play and is in great shape! Works perfectly, does not come with 9v AC battery adapter but it does come with its original case. Only thing to watch out for would be a few minor scratches it has received throughout time. ”

“Item is being offered again due to the failure of the buyer to pay for this item!

This auction is for a KORG POLYPHONIC SYNTHESIZER Model PS-800 with a KORG AC Adapter. Its serial No. is 078948. I know next to nothing about synthesizers. I connected the AC adapter and the unit powered up (see pictures). I have no idea how anything works. All the keys respond and nothing sticks. This is a very nice piece of equipment. It appears that someone really took care of it. I don’t see anything broken or missing but I must sell it AS IS since I don’t know how it works. I bought it at an estate sale where they were selling a lot of professional looking musical equipment and instruments. Consider my pictures as part of my description. ”

“Full working order, lovely sounding synth but I am getting rid of anything I don’t use. This is the second one I’ve had and I bet I buy another in the future!

Works as it should. It has a battery mod (the mk1 Poly 800s don’t have internal batteries as standard) and it was retaining its settings last time I used it it. I turned it on to test it and it has lost its settings so I guess the battery is dead (I’ve not used it for ages), so I’ll include a new battery with the sale. ”
