Korg Poly 61 Synthesizer is the Grit! – Jim Atwood in Japan

wordpress.com

The Korg Poly 61 Synthesizer is a hidden gem for synth enthusiasts, offering fantastic sound quality and a dream joystick for sound variation. Despite the annoyance of limited knobs for sound editing, it remains intuitive once you get the hang of it. The lack of MIDI connectivity in the non-M version might deter some, but the synth's ability to produce rich sounds makes it worthwhile. The arpeggiator adds to the fun, making it a great value, especially at a bargain price. However, potential buyers should be wary of the original battery's tendency to leak, which can damage the main PCB board. Overall, it's a vintage piece that's worth the investment for those willing to navigate its quirks.

Korg Poly-61 | Vintage Synth Explorer

vintagesynth.com

The Korg Poly-61 is an intriguing mix of affordability and nostalgia, offering a budget-friendly entry into the world of vintage synthesis. While it boasts reliable dual DCOs and a beloved arpeggiator, the synth's filter falls short of the Polysix's richness, with only seven resonance steps. Its programming method mirrors the Poly-800 and Yamaha DX-7, which might limit appeal for real-time tweakers. Early models lack MIDI, though this was addressed in the Poly-61M. Despite its limitations, the Poly-61 is a decent option, especially for those seeking unique, gritty basses and analog effects on a budget.

Korg Poly 61 (12T Dec 82)

muzines.co.uk

The Korg Poly 61 impresses with its dual-oscillator setup and a sleek design that outshines its predecessors. For under a grand, it delivers fuller, warmer tones and superb string and brass sounds. However, it suffers from limited fine-tuning capabilities, which can be irksome in a studio setting. Lacking white noise and individual modulation wheels, its interface may feel sluggish as you navigate its parameters. Despite these drawbacks, its rich sound palette and affordability make it a strong contender for those seeking a capable polysynth.

A simple specialist

The Korg Poly 61 is a versatile synthesizer that excels at crafting lush pads, thick basslines, and evocative leads reminiscent of the Blade Runner era, all without relying on built-in effects. While it lacks onboard effects, connecting it to external gear can elevate its sound to even greater heights. Its technical architecture bears resemblance to the Roland Juno 106, featuring DCOs (Digitally Controlled Oscillators) and Voltage Controlled Filters (VCF), characteristic of the iconic early '80s synth sound before the DX7 era.

While the Juno offers superior parameter control and flexibility, skilled individuals with a knack for electronics can easily modify the Poly 61 to enable external control through variable resistors, sliders, or even external CV/Gate signals.

Unfortunately, many used Poly 61 units suffer from battery leakage, which can corrode the circuits on the CPU board and connector pins inside the plug. This corrosion may also spread to neighboring boards through cables. Hence, it's advisable to thoroughly inspect all connectors, cables, and circuitry if purchasing or servicing one.

Preferred Settings + Usage:

Critics have occasionally pointed out that the Poly 61 doesn't quite match the sound quality of its predecessor, the Korg Polysix. However, I find its sound to be unique and commendable. While it lacks a dedicated Unison Detune knob like the Polysix, achieving thick bass tones is still achievable through creative techniques. For example, tweaking the LFO pulse width or employing slight detuning in Chord Memory mode buffering two notes at different octaves while setting DCO1 to SAW, DCO2 to square, both at the same octave but detuned 3-4 pitches against each other. By buffering two notes of this sound with an octave difference in hold mode and then switching to chord memory mode, you can achieve a four-voice unison sound, with two slightly detuned voices serving as its own type of sub-oscillator akin to the Polysix (which only has one suboscilator). The slight detuning between the saved notes is facilitated by the Poly 61's inherent detuning, which increases slightly as notes ascend, adding to its sonic character as stated in the manual. This trick leads to a unique kind of sound with its own character, while also evoking the iconic warmth of the Korg Polysix. It is noted, that in comparison to this method which leads to 4 detuned notes at a time, buffering the same note 6 times does make a full unison sound which is limited to the 2 oscilators beeing detuned to each other.

worth the buy in

This is like a jx3p if korg made it. Same filter and sweet but hissy chorus as the later DW6000. Same fun joystick for switling through pitch bend and LFO mod. If you like that sound and can deal with the amateur grade keybed (even by 80s standards), 2 digit parameter selection and data slider interface but want regular DCOs with regular shapes? Bingo. Highly recommended. Get an M with MIDI if possible. Limited implementation but usually the upcharge for an M is less than a MIDI retrofit and how many features do you need anyway?

This is not anything to do with the polysix.... just 6 voices and a similar name. DCOs, no SSM filter chip (I think the korg filter has more character anyway, SSs were ubiquitous in the 70s like CEMs in the 80s anyway)... 2 oscillators, more robust architecture. Its really a DCO DW6000. The enxt evolution was wave memory oscillators and the the DW8000 with digital delay and 2 more voices.

I wish I knew of this PolySix successor 10 years ago. Thanks for helping me integrate the 61 into my mental map of every 80s polysynth.

Classic analog synthesizer from 1981

The KORG Poly 61 is one of the first polyphonic synthesizers in the history of electronic music. It impresses with the sonorously dynamic synth sounds of the 80s. This synth has been used in many internationally successful productions. With its digitally storable soundbanks it offers a wide range of applications for the lover of vintage analog keyboard sounds. On stage it impresses with its easy handling. Retrofitted with MIDI or in the factory equipped version with MIDI it is also a very interesting sound supplier within the wide synthesizer family.

I think its more like in the 2nd or 3rd run of polyphonics LOL, just in korgs you have the polysix prior... also prior are the CS80, prophet5 prophet600, 2 voice, 4 voice, 8 voice, OBX, XA, OB8, jupiter4 and 8, juno6 and 60, Akai AX series was earlier or contemproary as was the Teisco/Kawai SX series and the Elka Synthex if I recall... but great review.

Poor man's Juno

Really cool anolog synth with digital clocking, parameter adjustments and preset saving. Fixed one and almost sold it, glad that didn't happen. The arpeggiator function is tons of fun, especially at faster speeds with sounds that have a quick attack.

Poor man's JUNO ??? ... I don't realy think so! ... when I Bought this f***ing K'board at the age of 19! ... it was very expensive to me: 2.100 DM ( in 1981 it was nearly the same as my fathers monthly netto-earnings as an engineer!)

You never forget your first...

The Korg Poly-61 was my introduction to analogue synthesizers. The first time I turned on the arpeggiator I was hooked for life. An underrated classic.
