Korg nanoKEY2

Fifteen years the default keyboard-in-a-laptop-bag — and the thing owners mention most is the thing they like least.

The 25-key member of Korg's 2011 nanoSERIES2 (model NANOKEY2BK/WH) — flat, velocity-sensitive laptop-style keys in a 16 mm slab, with octave, pitch, modulation and sustain BUTTONS and nothing else. Black and white are the same instrument. Not the 2008 original nanoKEY, not the battery-powered Bluetooth nanoKEY Studio, and not the 2024 foldable nanoKEY Fold. No pads, knobs, faders, wheels, aftertouch, pedal jack or 5-pin MIDI.

Korg's nanoKEY2 has been on sale since 2011, which in computer-music years is roughly forever. It is two octaves of flat, velocity-sensitive keys in a slab 16 mm thick and 244 grams heavy, powered and connected by a single USB cable, with four buttons down the left side standing in for every wheel and knob a bigger controller would have. It was the answer to a narrow question — how do you enter notes into a DAW when there is no room for a keyboard? — and it has stayed the answer long enough that Porter Robinson and Laidback Luke have both been photographed with one.

It is also, by a comfortable margin, the piece of gear in this category that people are most divided about. Across more than a thousand owner ratings the single most-discussed thing about the nanoKEY2 is how the keys feel, and it is the one topic where the comments run two to one against. Everything else — that it fits anywhere, that it just works, that it costs very little — is close to unanimous. The argument is only ever about the keys.

The overview

A 25-key USB controller built around portability rather than playing. Sources agree almost completely on what it is good at: it is genuinely pocketable at 325 × 83 × 16 mm and 244 g, it is bus-powered from one cable, and on Mac, iPad and Linux it is class-compliant and works the moment it is plugged in. They agree just as clearly on what it lacks — every control is a button, so there is no fine pitch bend, no modulation sweep, no knob, no fader, no pedal jack and no MIDI out. Opinion splits hard on the keybed: reviewers who compare it with the original nanoKEY or with typing notes on a computer keyboard call it a real improvement, while owners who compare it with a sprung mini-key synth bed find the velocity range too narrow and the action too flat to play dynamically. Build divides the same way, between sturdy-enough-for-a-bag and visibly cheap. Windows setup divides too, and there the cause is documented: the hardware is class-compliant, but Korg's optional Windows USB-MIDI driver is where the trouble lives.

Where they agree

  • Genuinely pocketable — 325 × 83 × 16 mm and 244 g, powered by the same USB cable that carries the MIDI
  • Class-compliant: on Mac, iPad and Linux it is recognised the moment you plug it in, with no driver and no setup
  • Velocity sensing works and is adjustable, and the sustain button — new to this generation — earns its place
  • Every control is a button: no knob, fader, wheel, pedal jack or MIDI out anywhere on the unit
  • The KORG KONTROL EDITOR is still maintained, and is the only way to change the velocity curve

Where they split

  • The keybed: a clear step up from the original nanoKEY, or flat laptop-style switches with too narrow a velocity window to play dynamically
  • Windows setup: plug-and-play for some and a driver fight for others — a split that tracks Korg's optional driver, not the hardware
  • Build: sturdy enough to throw in a bag, or visibly cheap plastic with occasional fit-and-finish slips

Portability

Strong consensus · 8 src

The one thing nothing in the set argues about. Even the two-star reviews concede it: at 244 g and 16 mm it goes wherever a laptop goes, and it takes its power from the same cable that carries its MIDI.

“They're all about making music on the move or saving precious desk real estate, and the nanoKey 2 fulfils this role well.”

Computer Music, via MusicRadar

“A software-customizable keyboard that is so small you can fit several of them in your laptop bag!”

Thomann UK owner review

“This makes it very portable and easy to put in your bag for making music on the move.”

Digital Piano App
Measured

325 × 83 × 16 mm and 244 g, drawing under 100 mA of USB bus power — about the footprint of a laptop's own keyboard, and lighter than a paperback. Amazon's topic tally runs 43 positive to 3 negative on portability across 1,277 ratings.

Keybed

Contested · 9 src

Sources split, and the split tracks what each one is comparing it to. Measured against the 2008 original nanoKEY — or against typing notes on a computer keyboard — the reviewers call it clearly better and properly playable. Measured against a sprung mini-key synth bed, owners find the travel too shallow, the velocity window too narrow to shape a phrase, and the keys audibly loud.

Measured

Korg's specification lists 25 velocity-sensitive keys and four velocity settings — three curves plus fixed — with no aftertouch. Amazon's per-topic tally makes the split countable: key feel is the most-mentioned topic of all at 52 mentions, and runs 18 positive to 34 negative, with playability at 5 to 17 and tactile experience at 10 to 15 — inside a corpus that runs 43 to 3 on portability.

⚠ vs. listeners — Korg's own later nanoKEY Fold answers both halves of the complaint by name: it advertises a “Silent keybed” and velocity “customized to your feel with 13 different levels”, against the nanoKEY2's four settings and its decade of owner reports that the keys are loud. The measured facts back the sceptics on range; the enthusiasts are describing the same keybed against a lower bar.

Where it splits
a real step up from the original — playable, and velocity that works34%

“One big problem with the original nanoKey was that the velocity response varied wildly if you didn't hit each key dead-centre, but there's none of that with the new version, and it's a lot more playable for it.”

Computer Music, via MusicRadar
flat laptop switches with too little velocity range to play dynamically66%

“The velocity sensors do not feel like they have a big range, which is something to take into account when using or creating patches that are very dependent on velocity.”

Controls

Moderate · 5 src

Broad agreement on the facts and a spread only in how much people mind. The sustain button is new to this generation and universally welcomed, the octave buttons light up in different colours to show where you are, and the mod and sustain keys no longer sit flush against the lowest key. But pitch and modulation are momentary buttons rather than wheels or ribbons, so there is no fine control at all — and the original nanoKEY's CC Mode, which let the keys send control changes, was dropped.

“Unfortunately, there is no fine control these are just simple click buttons.”

engineeermusic, Equipboard

“The mod and sustain keys on the original model were flush to the lowest key of the keyboard, leading to accidental triggering if you weren't careful, but a few millimetres of plastic casing now separate them, which helps.”

Computer Music, via MusicRadar

“The modulation button is similar to the previous version, though I have not found this feature useful unless one is performing live.”

livewidmusic, Audiofanzine
Measured

Korg's specification lists the entire control set: pitch up/down, octave up/down over a −4 to +4 range, MOD and SUSTAIN. All of them are buttons; there is no knob, fader, wheel, joystick or touch strip anywhere on the unit.

⚠ vs. listeners — The nanoKEY Fold replaces exactly these buttons with “Two touch sliders for performance and control” assigned to pitch and modulation — Korg conceding, in its own copy, the limit owners have been naming since 2011.

Integration

Contested · 7 src

Sources split, and for once the cause is documented rather than guessed. The nanoKEY2 is a class-compliant USB MIDI device, so on macOS, iOS and Linux it is recognised with no driver and no setup — and that is what the reviewers and most owners report. The negative cluster is entirely Windows, and it is not really about the hardware: it is about Korg's optional multi-client USB-MIDI driver, which has broken across Windows updates and gets confused on machines with many MIDI devices. The fix the community converges on is to hand the unit back to Windows' own generic driver.

Measured

Korg's downloads page for the nanoKEY2 lists a Windows USB-MIDI driver (v1.15 r63e, updated 20 January 2026) and no macOS driver at all — because macOS does not need one. Amazon's tally, meanwhile, runs 33 positive to 3 negative on ease of use and 42 to 3 on functionality.

⚠ vs. listeners — MusicRadar's “no need for drivers” and the Windows owners' fury are both correct and describe different software. Cakewalk's own developers land on the same conclusion in that thread — swap the Korg driver for Windows' generic USB Audio device and the unit works in the DAW and in Korg's editor alike.

Where it splits
class-compliant — plug it in and it is simply there61%

“All are USB-powered class-compliant MIDI devices, meaning that you just plug them in and off you go - no need for drivers or external power supplies.”

Computer Music, via MusicRadar
on Windows, Korg's own driver is the problem39%

“We can inform you that KORG USB-MIDI Driver and KORG BLE-MIDI Driver are not compatible with Windows 10 May 2019 Update and advise you not to update your operating system until compatible versions has been released.”

Connectivity

Moderate · 5 src

One mini-USB socket, and that is the whole list. On the plus side it is bus-powered and works over the Camera Connection Kit with an iPad, over Linux, and with hobbyist hardware — owners report it running on every platform they tried. On the minus, the port is a dated mini-B, and there is no 5-pin MIDI, no TRS MIDI, no sustain-pedal jack, no battery and no wireless.

“Compatibility is as advertised (used it on Win, OSX, Linux, iOS -garageband and Arduino Mega ADK)”

no13, Thomann UK owner review

“Connectivity to an Apple's iPad (supports from iOS 4.2.1) using Apple's iPad camera connection kit is very handy for musicians on the go these days.”

livewidmusic, Audiofanzine
Measured

Korg's specification lists exactly one connector — mini-USB — and USB bus power under 100 mA. No DIN, no TRS, no pedal input, no wireless. Korg's later nanoKEY Fold advertises “USB-C and TRS-MIDI compatibility”, which is a measure of how far the port on this one has aged.

Build

Contested · 6 src

Sources split on the same slab of plastic. One camp reads it as robust in the way a thing built for a bag should be — flat, light, nothing to snap off. The other reads it as cheap: hollow to the touch, with a scattering of reports about panels that do not sit quite flat. Amazon's owners lean to the second, seven positive against sixteen negative.

Measured

Amazon's topic tally runs 7 positive to 16 negative on build quality across 1,277 ratings — the same corpus that runs 43 to 3 on portability.

Where it splits
sturdy enough to live in a laptop bag51%

“The case is plastic but feels pretty sturdy and the keys are flat. You don't have to worry about breaking it when slipping it into your laptop bag.”

engineeermusic, Equipboard
visibly cheap plastic, with occasional fit-and-finish slips49%

“The underside of the device was slightly bent upwards, so it wouldn't sit flat on my desk if it wasn't for those tiny rubber pads in the corners.”

Manbanan, Thomann UK owner review

Software

Moderate · 5 src

Two different stories under one heading. The KORG KONTROL EDITOR — the only way to change the velocity curve or the button behaviour — is still being updated fifteen years on, and reviewers and owners alike say it is worth installing. The bundled licences are where people fall out: generous on paper, and repeatedly described as a maze of codes and downloads to actually redeem.

“It's still worth getting the editor, though, because you can set things like velocity curve and timing of buttons for pitch, mod, etc.”

Computer Music, via MusicRadar

“These bundles do not bring anything to the hardware, on the contrary, they are for the user a very negative start for the entire product!”

M.Alexis.M, Audiofanzine (site's own translation from French)

“The VST bundle is nice, but may not rock the world of a producer, who has already a vast VST collection.”

engineeermusic, Equipboard
Measured

Korg's downloads page shows the divide plainly: KORG KONTROL EDITOR is at v2.5.1, released June 2025, while the nanoKEY2's own System Updater has sat at v1.0.3 since June 2015. The software around the unit still moves; the firmware inside it does not.

Value

Moderate · 6 src

Broadly positive with a real dissenting strand. At around $75 it is cheap in absolute terms and most sources call it good value for the space it saves. The dissent is comparative rather than absolute: at this money an Akai LPK25 or MPK Mini brings knobs, pads and a sprung keybed, so several owners conclude they paid for thinness rather than capability.

“It's a decent product for it's price. The compactness gives it a lot of extra value.”

DoesThisCompute, Thomann UK owner review

“Space saver, but overpriced for what it is.”

engineeermusic, Equipboard

“I would say that for $68, the nanoKEY is a bit overpriced.”

livewidmusic, Audiofanzine
Measured

About $75 on Amazon in September 2026. Korg's own US shop lists $99.99 for black and $74.99 for white, both sold out; Thomann UK has it in stock at £48.

Best for

  • Entering notes and chords into a DAW from a laptop bag, a train tray table or a hotel desk
  • Mac, iPad and Linux users who want a controller with no driver, no power supply and nothing to configure
  • Producers who want a second, always-there keyboard beside a bigger controller
  • Anyone whose alternative is typing notes on a computer keyboard

Skip if

  • You want to actually play — dynamics, fast passages, anything you would call keyboard technique
  • You need a knob, a fader, a pitch wheel, a sustain pedal or a MIDI out
  • You record in a quiet room or near an open microphone — the keys are audibly clacky
  • You are on Windows and would rather not think about MIDI drivers at all
