An Incredible Price for a Powerful Analog Polysynth

Korg's Volca Keys analog synthesizer is a must-have for any fan of synths, packing huge analog tone and a surprisingly flexible interface into an ultra-affordable and portable package. This 3-note synth has self-tuning analog oscillators for stable pitch, and lets you stack notes to form chord stabs or combine them in unison for huge lead lines. Factor in the fat-sounding filter, delay effect, and a built-in arpeggiator, and you're well on your way to analog synth bliss. Best of all, you can store up to eight of your own patterns for recall anytime with the Korg Volca Keys.

Korg Volca Keys Analog Synthesizer at a Glance:
  • True analog synthesis with 3-note polyphony
  • Loop sequencer and Motion sequencer capture your performance
  • Truly portable, and easy to integrate with other gear
True analog synthesis with 3-note polyphony

Korg's Volca Keys is quite a flexible synthesizer, despite its compact size. Its 3-voice design lets you create 3-note chords, or combine them in unison for huge lead sounds. Even better, there's a built-in delay effect for incredibly vibrant sounds.

Loop sequencer and Motion sequencer capture your performance

Whether you're playing the built-in ribbon controller or triggering it via an external MIDI controller, the Volca Keys is great for on-the-fly creation. Use the loop sequencer to capture your idea, then use the Motion sequencer to record your knob-turning in real-time. You can easily twist one simple sequence into something entirely new, just one sure sign of a great synthesizer.

Truly portable, and easy to integrate with other gear

With its compact size and optional AC or battery power, the Korg Volca Keys is truly a go-anywhere analog synthesizer. Best of all, it's got the right connections to interface with any of your gear. It's got a MIDI input so you can control it via any MIDI sequencer, and it even has Sync I/O so it can play in time with Korg's Monotribe and Monotron analog synthesizers. Or simply create whatever synth sounds you like, then sample them for sequencing elsewhere.

Korg Volca Keys Analog Synthesizer Features:
  • Portable analog synthesizer with 3-voice design
  • Voices can be stacked as chords, or combined in unison
  • Record your own loops and phrases, then capture your knob-tweaking with the Motion sequencer
  • Sync In/Out makes it easy to play in time with Monotribe or other Volca machines
  • Control via the onboard ribbon or via MIDI input
  • Save your own patterns for later recall
  • Can sync to MIDI Clock from your DAW or external sequencer
  • Operates on 6 x AA batteries or KA-350 power adapter (not included)

Most Powerful Synth for the Price

This synth is the best that I have found for the price, and it has blown me away with how creative you can be with such a simple synth. I've tried finding cheap units like the monotron delay which is ultimately only good for as an effect unit and getting a dirty noisy sound, but this synth is so powerful on its own I can't believe it. It's as basic as you can get while still being able to have fun, and is a very effective learning tool on midi and hardware setup as well as instrument for simple sequencing and melodies. What is the greatest thing about this synth is the many versatile ways to play it in my opinion. You can power this on batteries and play it with its own built-in speaker for on the go boredom, or power this with their own supply and plug it in for hardware integration (not included). You can sequence a melody straight from the sequencer and save it, or you can plug a midi cable in and have it play a melody from your DAW. You can record motion with the sequencer as well, or apply your generic effects within your software or rig to add complexity to the sound. I would highly recommend this for any musician big on physical synthesizers regardless of level, for the many different ways to play it. Would also highly recommend this to anyone like me who is always looking around for cheap and usable hard synths. This is my final thoughts on the volca keys: Pros: Super easy to use in many ways Portability is as easy as it gets Super clean sound Many ways to be creative and record Overall clean look and feel Easy integration for other hardware and keyboards Neutral Comments: A little research and reading is needed to do some things like set midi channel etc Cons: Keys are very small, pretty hard to play in poly mode with chords on this Sequencer is a little crazy to work with Knobs are small (monotron small) Power supply not included If you can get passed the simplicity and small design, then this is a synth for anyone who loves them.

Sounds Great!

What's not to like? This super portable, very affordable synth sounds fantastic. This is the first analog synth that I've owned and I don't think I'm going back. This has great range and can easily create massive low end in your tracks or upfront leads. My favorite part is the pattern sequencer - I can lay in bed with headphones and try out sounds, record bass lines and then automate knob turns into the sequencer to really make the patterns I've recorded come to life. On more than a few occasions, inspiration has struck hard with this device and I immediately have to get up out of bed, go plug this into my audio interface and begin making a track. This thing is amazing and sounds even better when played via midi by a keyboard. I love it.


This is the same review I'd write for the Volca Bass and Volca Beats, they're all awesome, huge range, easy to learn, super fun and most importantly....analog! For the price it is so worth it! I bought a Hosa 1/8" stereo to 1/4" mono chord to go from its headphone jack into the Behringer 4 channel Micro Mix then into my Peavey Bass amp and you get a really great sound! Also, if you get the Korg SQ-1 you can synch them up or get the Hosa Midi cable and control the Volca Keys or Bass with that.

Sawtooth Polysynth

WARNING: THIS IS A SAWTOOTH-ONLY POLYSYNTH. It has a Square wave capability but only for the Ring Modulation. You will not hear polyphony for the Square Wave, only Ring Mod. That aside... This Sawtooth PolySynth is EXTREMELY simple. I wanted something that can do some nice pad chords. I was so Upset that it only had Sawtooth which is so harmonic that it could rarely ever be used in a soft way. But After a while, it grew on me so much. I find myself using for everything now, even though I have a whole collection of excellent synthesizers. It's just so liberating to have an analog polysynth in my little world of monosynths. But that's just the beginning. The several modes that you can select are all really great. No lie here... they're actually very useful, and not gimmicky. And I think the "Detune" knob is absolutely genius. The EG is the weakest point in my opinion, aside from the single waveform. I do not use the built in keyboard, I hook it up to my MPK49 as a controller. I route the faders to the MIDI Implementation CCs for the Volca Keys and the sound is tremendous without even any FX on it. And the crappy delay that's built in adds so much crazy Lo-Fi color. I have expensive synthesizers, but I can't put this little 150 dollar thing down!! Consider it a Module. That's how I look at it, like it's a Korg Sawtooth Polysynth Module. :) I regret the Volca Bass. I don't regret the Volca Keys.

A rockin' little synth..!!

The Volca Keys is a great little analog synth for a beginner to learn about analog synthesizers with, or the pro who wants something small and portable to bounce some ideas around with, when not in the studio. It would have been nice, if Korg had incorperated a mixer in it (for each of the VCOs) and a noise source (pink and white), but I guess you have to cut corners somewhere to keep the price down. I have been a little annoyed of what I've read from people on other sites, giving reviews of it though. Contrary to what they have been saying, this Synth's VCOs gives you 2 different waveforms, (a sawtooth and square)..not just a sawtooth. I guess those people should have had their hearing checked, if they can't tell the difference between a Sawtooth and Square wave, because they are as different as night and day.!! Plus, it tells you right in the owners manual about it having 2 different waveforms, not just one for the VCOs. A great little synth all in all, for the money. I would have liked to seen Moog come out with something like this, but I guess they dropped the ball on this one or were sleeping...
