Arturia KeyLab 88 mk3

The strongest point of agreement: every magazine review praises the TP/110 action as smooth, balanced and fast enough for synth runs while still feeling like a piano. The minority view is about noise and weight rather than feel — some owners call it a little clunky or noisy, and one owner of the same action elsewhere finds it light and plastic-on-plastic over time. Aftertouch is channel-only, which several reviewers flag as the flagship's missing piece. A late-2025 firmware briefly made some notes in every octave louder; the next update fixed it.

“This is a notably fine action for the money, and helps the KeyLab 88 MkIII carve out a distinct niche in the market.”

“Looking at just the keybed alone, the KeyLab 88 Mk.3 is one of the finest I’ve played.”

Gearnews

“It's not an action I'd want as my primary because it feels light and it's noisy.”

David B (TP/110 owner) · Piano World

“They are a little clunky. You can hear that.”

A Joe-Blog Composer (8-month owner review)

Sources split. Most reviewers find the 12 RGB pads solid, sensitive and pleasant to play, with a few calling them better than the mk2's. Others find them small, unreliable below low velocities and near the edges, and regret losing four pads from the mk2's 16.

Largely praised: the touch-sensitive faders and encoders feel premium and show their values on screen when touched, and Sound On Sound calls the on-board programming the clearest it has used. The complaints are about layout — faders on the right (awkward for playing with the right hand), pitch and mod wheels placed high on the panel — plus no scribble strips or fader markings. After firmware 1.2.1, two owners reported a pitch wheel that doesn't always return to centre.

“The programming system, with that very legible and bright LED screen, is the clearest and quickest of any MIDI controller I’ve ever used, by miles.”

“I just love how tactile and premium these faders feel.”

A Joe-Blog Composer (8-month owner review)

“Die Fader und Knobs auf der rechten Seite des Boards sind in meinen Augen ein Designfehler.”

Tobesn · Thomann ("The faders and knobs on the right side of the board are, in my view, a design flaw.")

“Another bug making this thing unusable for live performance.”

Control of Arturia's Analog Lab and V Collection instruments is the strongest part: bidirectional, mapped out of the box, with presets browsable from the screen. DAW integration is good in Logic, Ableton Live and Cubase via Arturia's scripts, but uneven elsewhere — some reviewers found DAW mode awkward or its mappings patchy, there are no dedicated scripts for Pro Tools, Reason or Studio One (MCU/HUI covers them), and a few owners hit configuration glitches in Logic and MainStage.

“Analog Lab V, part of the KeyLab’s bundled software suite, gives a slick and reliable hardware control experience.”

Sound On Sound

“Nothing integrates better, as you’d hope.”

AudioTechnology

“Disappointingly, at times it simply feels easier to reach for the mouse.”

MusicTech

“Die DAW-Integration variiert je nach Software – hier scheint Ableton Live und Logic aktuell am besten unterstützt zu sein.”

bonedo ("DAW integration varies by software — Ableton Live and Logic seem best supported for now.")

Consistently called a generous bundle: Analog Lab Pro with 2,000+ presets, Piano V, Mini V, Augmented Strings, Rev PLATE-140, NI's The Gentleman, Ableton Live Lite and trial subscriptions. The caveat is that deep editing of most instruments means buying them or the V Collection.

“It ships with a generous raft of software, including Arturia’s Analog Lab Pro, a handful of Arturia’s V Collection instruments, Ableton Live Lite, Loopcloud and more”

MusicTech

“but for full emulation, you’ll need to purchase the instrument or the V Collection.”

Audiofanzine

Pedal players get four pedal inputs, and USB-C bus power runs the whole keyboard; there is full-size MIDI in and out. But the mk2's CV/gate outputs are gone, no power supply is included, and one reviewer wanted a locking USB-C socket for stage use. The bigger story was the sustain pedal: on launch firmware it sent delayed or intermediate values that choked notes, which owners documented with MIDI monitors, and some returned their units over. Arturia acknowledged it and fixed it in firmware 1.2.0 (December 2025), with further pedal fixes in 1.5.0 (May 2026).

“If you’re into pedals, you’ll like the KeyLab.”

Sound On Sound

“There are no options here for modular equipment.”

Audiofanzine

“I can confirm the delay also on my 88-mk3.”

RolandKirst · Arturia forum

“Fixed a key latency issue that could occur when using the sustain pedal.”

Arturia firmware 1.2.0 notes · r/Arturia_users

It's a big keyboard at about 16 kg, and reviewers and owners treat it as a studio or stage fixture rather than something to carry casually. Against other hammer-action 88s it is on the lighter side, and it runs on USB bus power alone.

“Yes, you may need a friend to help you unbox this one — it’s simply massive.”

MusicTech

“Incredibly, the whole thing is bus-powered over USB-C, which feels completely improbable but is a welcome surprise.”

MusicTech

“Mit 15,7 kg Gewicht gehört das Keylab 88 zu den leichteren 88-Tasten-Controllern”

amazona.de ("At 15.7 kg the KeyLab 88 is one of the lighter 88-key controllers")

Reviewers, all on loan or early units, call the build premium — metal base, wooden end cheeks, firmly mounted controls, sturdy accessories — and an eight-month owner's unit survived a tea spill. Owners add a less even picture: a unit with sticking keys and a resonant, hollow-sounding case (returned), a dead key, a rattling key, sideways play in black keys and easily scratched white keys. Audiofanzine notes the top is mostly plastic over an aluminium base.

“The build quality is gorgeous: a sturdy enclosure with wooden sides and firmly mounted controls.”

MusicTech

“It feels solid. It feels like a keyboard that's going to last me.”

A Joe-Blog Composer (8-month owner review)

“Most of this keyboard is also solid plastic, but the base is aluminum.”

Audiofanzine

“Das Gehäuse ist so hohl gebaut und resoniert so stark, dass man selbst durch Kopfhörer das laute Geklopfe der Tasten hört”

Maik Goltz · Thomann ("The case is built so hollow and resonates so much that you hear the keys knocking even through headphones")

“Keyboard had a dead key. Pain in the ass to return.”

Amazon owner review

Sources split, though unevenly. Most reviewers call it good value — a top-tier hammer action, full control surface and a big software bundle for less than Native Instruments' S88 mk3. A smaller group, mostly KeyLab mk2 owners, sees the mk3 as a downgrade: CV outputs, four pads and the buttons under the faders are gone, and there is still no polyphonic aftertouch. Arturia's own list price has since risen to $1,299, while retailers sell it for about $849–$999.
