“I replaced the side panel. Its not stock. All the original clips are put back, but some screws are not original. It plays really nice. Once you get used to the slider, its easy to use the value lever to program, and in performance on the filter , envelopes etc.
You have alot of performace control with the live buttons on the panel , chord memory, hold, 9 different arpegiator positions, either latched or unlatched, live speed control. the joystick is and XY postions so you can blend the pitch bend with the filter, or vibrato modulation. The pitchbend goes up to an oct up and down, and has a live knob control that amount, and another knob to control the frequency speed amount.
Tuning knob on the panel.
Pedal controls include, sustain, program up, arppegio trig in,
High and low main out, AND headphones out
This synth really is a monster, and it does some unique sounds when you push the edge of some of the controls, like good analog synths do.
It takes a minute for the osc to stablize, which is normal for the poly 61m till it warms up. But it tunes itself”

“Works great. Tunes up in 5 minutes like it should. Stays in tune. All arpeggiation , chord hold, pedal midi etc works as should. Programable, all original, except one side panel which are particle board, was coming apart, so I re-fashioned a solid wood piece and re-built it. It’s sturdier than new.
“PREOWNED IN GOOD WORKING CONDITION ”
“Original box! KORG POLY 61 Synthesizer in Excellent cosmetic condition. The tech I took it to said it just needed a new battery, but I never got around to putting one in.Condition is For parts or not working.”
“Korg Poly 61 Analogue Polyphonic Synthesiser – with Midi Kit (not yet installed). Synth is in great condition given its age, all the key beds are great and plays really well.” 
“The unit powered up fine but the keys would only make a popping sound. I had read about the bad internal batteries so I had a new one installed even though the old one had no signs of leaking anywhere. That did not fix the problem and that is about as far as I can go with the repair without knowing how to test for problems. I am selling the keyboard as/is since I have no clue what the issue may be. If you would like the old battery I can enclose that with the keyboard.” 
“Comes as seen
“I had to rebuild one side with a new piece of wood. It looks ok, and is very sturdy solid piece
“Great piece of equipment, has just been sitting sadly. Need to let it go.” 
“NOT FULLY FUNCTIONAL makes awesome sounds, you can select any kind of sound but it is stuck on a drone. NEEDS REPAIR! GOOD CONDITION COSMETICALLY!I think it needs to have the Key Contacts under the each key repaired maybe? There are several wizards online who know how to easily fix this DIY!” 
” REALLY COOL 1980’s VINTAGE ANALOG SYNTHI dont have the time to fix it but it will be awesome given the proper repair Love and Care!LOOKS GREAT!”

“some wear, considering it is about 35 years old. Has been in storage for 20 years, but is in working condition. Some keys stick or need to be played harder before they will sound”
“Working Korg Poly 61 Analog Synth, comes with a digital copy of the manual. As this is a vintage synth, it will need some TLC.
“Up for sale is a fully serviced and 100% functional Korg Poly 61 vintage synthesizer. The original NiCad battery has been removed and replaced with a much more reliable lithium type.
“FS: Clean #Korg #Poly61. 3&4 numeric buttons double-press at times but totally work (replacing tact switches of all numerics would be wise at some point). Also, 1 or 2 keys need their contacts reseated/cleaned. Again, all work but I’m a very discerning seller who strives for maximum accuracy. If you’re wanting an 80’s 2 DCO polysynth with a lush sound akin to the Juno 6/60 and has an arpeggiator w/ arp input for stepping via a trigger/gate and doesn’t break the bank, this is it. ”
” 1983 Korg Poly 61 home use only never gigged I’ve owned it from new, works fine. cosmetic damage to C key one octave down from top,(see photo) replacements are about £6 off e-bay. I’ve lost the manual but it is self explanatory parameters are printed on the top as you can see, so you type in the parameter number and adjust as you key the sound, simples. Collect only please.”
“Korg Poly-61 vintage analog synth for parts only. It powers on and produce sound, but does not sound correct. Sold As-Is.”
“FS: Korg Poly61: 80’s 2 DCO goodness with chord memory & an arp (arp can trigger chords in chord mem mode). Theirs also an arp trig input for stepping the arp ala #Juno60/6. Filter sounds a lot like the #DW8000 to me. Everything works. A few of the numeric buttons could stand to have their tact switches replaced, but they do work. Sold as-is due to the unpredictable nature of vintage synths.”
“The Korg Poly 61M, first of the Nobless synthesizers, is the same as the Poly61 but with a MIDI in/our port. This machine is in superb shape, with excellent circuit board, and all components are in full working order. The best way to see how amazing this instrument this is, is by watching a short tutorial on the two best selling points of this instrument- the arpeggiator and, of course, making programs that can be saved to memory. The biggest cosmetic defects are a ding in the back corner (visible in the power-cable photo, and some spray paint dots on the left side).
“Vintage Korg synth, the unit powers up and makes some noise but not the correct sounds. I believe this is may be due to the internal battery failing. Lots of potential” 
“Nothing comes up on the display
“Serviced one month ago at the excellent keyboard repair department of Main Drag in Williamsburg, Brooklyn, this Korg Poly-61 M works perfectly, has cleaned pots and switches, and comes with all the original factory presets on board. Has a few cosmetic dings and nicks on the wooden side panels, but otherwise like new. Condition excellent / very good. RARE. This is the only one I’ve ever seen. Arpeggiator and joystick plus the chord memory feature make this a unique addition to anyone’s analog keyboard collection. Great for the ‘Stranger Things’ vibe too. Gritty 80s basses, weird squiggly strings, fun to play with the joystick to modulate the sounds.”
