Korg Volca FM2 Review
Korg Volca FM2: Like a Miniaturized Yamaha DX7 in Your Pocket
Korg's value-priced Volca FM2 brings all of those big, polished pop-song sounds of the '80s wherever you go. This clever 6-voice, 6-operator FM synthesizer contains all 32 classic algorithms, an easy-to-use 16-step loop sequencer, effects, reverb and chorus effects, and a funky arpeggiator. Korg claims that it perfectly reproduces the sound of the classic Yamaha DX7. I haven't tested Korg's claim because I don't have a DX7 as of this writing, but the Volca FM2 sounds great. If you're looking for an affordable and fun FM synthesizer to mess around with, don't sleep on the Volca FM2.
How Does the Korg Volca FM2 Sound?
Before you dig into custom patches and editing and get seriously nerdy, there are more than enough presets to get started creating your own songs right out of the box. Chords shimmer with crystalline clarity, basses growl with a familiar metallic bite, and its overall sound evokes nostalgic ’80s futurism. You know its sounds of bells and glass, the FM2 is like an old friend with plastic knobs.
But wait! There's more than just presets. Under the hood lies a fully editable FM engine with the same architecture that once intimidated producers with pages of menus and cryptic parameters back in the day. On the FM2, those parameters are all there, but paired with hands-on control, a sequencer, and MIDI integration.
For those looking to start making songs right away, rather than going into the Volca FM trying to create a particular sound, tweak the sounds that Korg gives you with its transpose and velocity sliders, modular and carrier attack and decay, LFO, algorithms, and more. You don't even need to know what these things mean to get started, just fiddle around and see what does what.
The first preset that you'll encounter is Arctic, which starts with a shimmering frozen lake and then adds layers of bass swell. Mess around with the knobs and sliders to see what happens to it. Then move into some of the other presets and fiddle with them. You'll discover some pretty neat sounds right away.
How Well Built is the Korg Volca FM2?
Like Korg's other Volca models, you get what you pay for when you buy the FM2. Its plastic construction is more or less the same as the rest of the Volcas. The FM2 is light. It feels sturdy enough to toss in your backpack and go, but still a bit vulnerable to the elements because of its little protruding knobs and the plastic sliders that collect dust. If you plan to travel with it a lot, perhaps you should invest in a case.
Is the Korg Volca FM2 Fun to Play?
The Volca FM2 is a stylish little synthesizer that is powered by six AA batteries or an external battery pack. The MIDI in and out, sync in and out, and headphone jack are right where you need them to be. The knobs feel cheap, but they light up and blink which is nice.
The Volca's touch keyboard is nice for messing around with ideas and navigating the menus. Serious players will want to hook up their own MIDI keyboard. I use MIDI sequencers to drive mine and love it.
I like the "somewhat gold-tinted" black faceplate and gold highlights... and I don't even like gold that much. The green buttons are a nice touch. Presumably, Korg gave it a bit of throwback 1987 styling, and it works. This keyboard would be right at home on stage with Jem and the Holograms. If this is your first Volca, I suspect you'll buy more. Korg did a good job styling the FM2.
Deep Dive into the Volca FM2
The Volca FM2’s 16-step sequencer can store up to sixteen patterns, and you can chain them for longer phrases or full song structures. Motion sequencing lets you record knob movements in real time, so your FM patches can evolve dynamically as the loop plays. Combine that with the onboard chorus and reverb, and you can build lush, animated textures that sound far bigger than a palm-sized synth should allow.
Once you get past the presets and start exploring the edit functions, the Volca FM2 reveals its true depth. Every DX-style parameter is accessible if you’re patient enough to navigate its menus, and with the updated firmware, Korg gives users velocity sensitivity via MIDI, which makes a world of difference when sequencing from an external keyboard or DAW. The six voices mean you can play some lovely chords.
The FM2 also speaks full DX7 SysEx, which means you can import classic Yamaha patches into it. There are thousands of DX7 sounds floating around the internet, and loading them via MIDI librarian software transforms this little box into a portable DX archive.
Portability remains one of the Volca line’s biggest strengths. It runs on batteries or USB power, has a built-in speaker, and syncs easily with other Volcas or pocket-sized gear. You can toss it in a bag and compose on the go, or hook it into a studio chain through MIDI and treat it as a compact FM module.
If there’s a downside, it’s the same one shared by most Volcas: tiny knobs and limited screen real estate. Editing FM operators on its miniature display can feel tedious, and without an external editor or MIDI controller, deep programming sessions can feel like a chore. If you truly want to go DEEP into FM synthesis, I might suggest something more powerful like Korg’s pricier Opsix. For less than $200, the Volca FM2 is perfectly capable, given its limitations.
Ultimately, the Volca FM2 captures everything appealing about the Volca series: affordability, immediacy, and character. It’s not meant to replace a full-sized DX7 or an advanced FM synth, but it nails that balance between nostalgia and modern convenience. Whether you’re sequencing robotic funk lines, layering glassy pads over a beat, or just noodling late at night, the Volca FM2 inspires hardware-centric creativity and feels fun to use.

Frequently Asked Questions | Korg Volca FM2
What is the Korg Volca FM2?
A compact, battery-powered FM synthesizer that recreates classic 6-operator DX-style sounds with modern extras like motion sequencing, effects, and sync, designed for portable jams or studio rigs.
How many voices of polyphony does the Volca FM2 have?
Six voices (the original Volca FM had three). The extra polyphony makes chords and layered parts much smoother.
Is it compatible with Yamaha DX7 patches?
Yes. It’s compatible with DX7 SysEx; you can import classic DX7 sounds and use all 32 FM algorithms.
What’s new versus the original Volca FM?
Key upgrades include 6-voice polyphony, MIDI OUT, expanded patch memory, and added reverb (alongside chorus), plus quality-of-life tweaks for sequencing and performance.
How many presets/patches can it store?
Factory presets plus user slots—expanded compared to the original model (commonly 64 or more total slots depending on bank configuration). You can also load additional patches via SysEx.
Does it have built-in effects?
Yes. Chorus (signature DX-style sheen) and reverb are on board for instant space and width.
Can I sequence parameter changes?
Yes. Motion Sequence records knob movements into your pattern, so you can animate timbre, effects, and more over time.
Does it have an arpeggiator?
Yes. It includes a flexible arpeggiator that pairs well with motion sequencing and the 16-step sequencer.
Is it velocity-sensitive or aftertouch capable?
The Volca’s touch strip isn’t velocity-sensitive, but velocity data over MIDI is supported, so an external MIDI keyboard with velocity can control dynamics. Aftertouch is typically passed if your MIDI routing sends it to mapped parameters.
What are the I/O connections?
-
Audio out (3.5 mm)
-
Sync In/Out (3.5 mm) for chaining with other Volcas and pocket gear
-
MIDI IN and MIDI OUT (FM2 adds MIDI OUT compared to the original)
-
DC 9V power jack
Does it run on batteries and have a speaker?
Yes to both. It runs on AA batteries and includes a small built-in speaker for truly portable use.
Can I clock/sync it with other gear or a DAW?
Yes. Use Volca Sync (click pulses) with other Korg gear or MIDI clock via your interface/DAW. The new MIDI OUT lets the FM2 drive external devices, too.
Is microtuning supported?
The Volca FM series supports alternate tunings; FM2 maintains that flexibility so you can explore scales beyond equal temperament.
Who is the Volca FM2 for?
Producers who want authentic 6-op FM tones in a small box, DX7 patch compatibility, hands-on sequencing, and portable jams, without the size or price of vintage hardware.
