Arturia MicroLab mk3

The short version

What to know.

A 25-key slim-key USB-C MIDI controller, around $59–69, built for travel and for adding real keys to a laptop, tablet or USB-host groovebox. Sources broadly agree on the strengths: a keybed that is even, quiet and a size larger than most mini keys (the same one as the MiniLab 3), a light and genuinely bag-friendly body, plug-and-play class-compliant USB with handy Analog Lab preset browsing from the panel, a starter software bundle, and value that is rarely disputed. Three things split opinion. The control surface — two touch strips, four buttons, a chord memory and a hold latch — is minimal by design to most reviewers and simply too little to others, who miss knobs, faders, transport buttons, an arpeggiator and the semitone transpose the spec sheet promises but the unit lacks. Connectivity is USB-C plus a pedal jack and nothing else: fine for the concept to one camp, a deal-breaking omission of a MIDI out to the other. And build reads as solid and surprisingly thick to most, while long-term owners of the original note the rubber bumper shell is gone and the mk3 is more exposed on the road. No aftertouch, no pads, no DAW scripts.

About this product

The third-generation MicroLab (May 2025 — Arturia skipped an 'mk2'): 25 slim velocity-sensitive keys borrowed from the MiniLab 3, two capacitive pitch/mod touch strips, four buttons (Shift, Hold, Oct −/+), USB-C and a ¼-inch pedal jack, in black or white with wood-effect end cheeks. Distinct from the 2018 original MicroLab — a wraparound rubber bumper that stowed its micro-USB cable, no pedal input, orange/blue/black — and from the larger MiniLab 3 (pads, encoders, faders, a screen and a 5-pin MIDI out).

Arturia's MicroLab mk3 is the French company's smallest and cheapest keyboard controller: two octaves of the slim keys from the MiniLab 3, two touch strips, four buttons, a USB-C port and a pedal jack, in a 40 cm slab that weighs a little over a pound. It replaced the 2018 original — the one with the colourful rubber bumper and the cable that wrapped around it — in May 2025, launching at $89 and quickly settling to $59–69 on the street.

It ships with Analog Lab Intro and Ableton Live Lite and is pitched squarely at backpacks, coffee tables and cramped desks. Reviewers all say the same thing about what it does — the keybed is far better than a $60 mini controller has any right to be — and then split over what it doesn't: no knobs, no transport, no MIDI out, and no rubber armour any more.

A good fit for

  • Travellers and couch producers who want real keys in a laptop bag and nothing more
  • Owners of USB-host grooveboxes (Ableton Move, OP-Z, MPC) who want a one-cable keyboard
  • Arturia ecosystem users who will actually use the Analog Lab browsing shortcuts
  • Beginners who care more about key feel than about knobs — the keybed is the same as the MiniLab 3's

Think twice if

  • You want to drive hardware synths without a computer — there is no MIDI out
  • You need transport buttons, knobs or faders for DAW work — the MiniLab 3 costs a little more and has them all
  • You transpose by semitone, use an arpeggiator or want aftertouch — none are on board
  • You will throw it in a bag daily and valued the original's rubber armour — the mk3 is plain plastic

Common ground5

  • A genuinely good slim keybed — the MiniLab 3's — that is even, quiet and a size larger than most mini keys (measured 2–3 mm wider than Akai's or Novation's)
  • Light and truly bag-friendly: about 40 cm wide and 620 g, bus-powered over USB-C, the smallest keyboard Arturia makes
  • Plug-and-play class-compliant USB, with hands-on Analog Lab preset browsing from the Shift functions

Points of contention3

  • The control surface: minimal by design and perfectly adequate to most, versus too little — no knobs, faders, transport or arp, and no semitone transpose despite the spec sheet — to a critical minority
  • Connectivity: USB-C plus a pedal jack is all the concept needs to one camp; the missing MIDI out is the deal-breaker to the other
  • Build: solid and surprisingly thick for the money, versus less travel-proof than the original now the rubber bumper shell is gone

Band: opinion spread · Dot: weighted average

The consensus strength, and the reason most reviewers forgive everything else. The 25 slim keys are the MiniLab 3's: editorial testers call them even, quiet and far better than typical mini keys, owners rank the velocity response among the best they have had, and two German tests measured why — the keys are 2–3 mm wider than Akai's or Novation's minis with slightly deeper travel. The dispersion is about feel and size rather than quality: one owner finds the springs too stiff for fast playing, one tester found them a touch light, and piano players still find two octaves of mini keys cramped. No aftertouch.

“Honestly, the keybed is where the MicroLab Mk3 really shines.”

KVR Audio

“The keyboard is actually pretty great for its size. It has a decent feel and resistance to it, it’s relatively quiet and it plays much nicer than the Launchkey Mini I currently have on my desk.”

Sound On Sound

“Despite being smaller than a regular keyboard it’s also very playable and is mechanically pretty quiet.”

MusicRadar

“The springs are too stiff, which makes fast play more difficult.”

Measured

Spec: 25 velocity-sensitive slim keys spanning two octaves, shifted up to ±4 octaves with the Oct buttons; no aftertouch. Bonedo measured the keys at roughly 83 × 20 mm — 2–3 mm wider than Akai's or Novation's mini keys, with slightly deeper travel — and Amazona measured the white keys at 8.8 × 1.9 cm. The MIDI Control Center offers linear, logarithmic, exponential and fixed velocity curves.

What to keep in mind 7

  1. A read of where opinion lands as of September 2026, sixteen months after launch — the budget mini-controller field moves quickly (Akai's MPK Mini IV and LPK25, Korg's microKEY and nanoKEY, Novation's Launchkey Mini and Arturia's own MiniLab 3 all shift where the value sits).

  2. The queue and many search results still say 'MicroLab'; the 2018 original — rubber bumper, wrapped micro-USB cable, no pedal jack — is a different product, and comparisons to it come mostly from people who owned it for years.
