Akai APC Key 25 MK2

The sharpest split here, and the reason to think twice. The positive case is first-party and echoed by both editorial sources: it is class-compliant, needs no drivers, and ships pre-mapped, so a current Ableton Live picks it up on plug-in. The negative case comes from people who plugged it in. It requires Live 11.2.7 or later, and setup routinely produces two devices — the guide itself says to choose the one marked (Port 2), which is precisely where owners get lost, reporting keys that play but no pad lighting and no red clip border, on Live 11 and Live 12 alike. The most persistent complaint is that the knobs cannot be remapped at all: Akai's FAQ says they can be mapped manually like any MIDI device, but two independent users on two different platforms report they cannot, and one of them notes it fails even in the way Akai's own demo video shows. Akai's troubleshooting page separately concedes the unit can drop out mid-session and blames USB power and hubs.

The reason this exists rather than an APC Mini, and the thing owners most disagree about. The facts are settled: 25 velocity-sensitive slim keys on what Akai calls its Gen 2 dynamic keybed, with octave buttons reaching a ten-octave range and a sustain button on the panel. Feel is where it splits, and the evidence is thin on both sides — one owner finds the action fine for what it is, another, who owns both this and the APC Mini, says the mini keys feel really bad and had a friend return the unit over it. Two limits are not in dispute: there is no pitch or mod wheel and no aftertouch, and even the sympathetic editorial note calls the octave and sustain buttons awkwardly placed, a complaint carried over from the MK1.

Contested, and on a real axis rather than a price quibble. The case for: $99 buys keys, a colour clip grid, eight endless knobs, transport controls and Ableton Live Lite plus three AIR instruments, and it is widely liked — 4.5 out of 5 across 653 Amazon ratings, 4.4 across 34 at Thomann, with owners calling it a good on-ramp. The case against is not that it's expensive but that the device is narrower than the button count suggests, so the money can end up idle: one owner of both APCs says his Key 25 collects dust, and a prospective buyer talked himself out of it once he understood the 40 buttons only launch clips. Amazon's own summary of its reviews reports that buyers split on ease of use and on value, with some finding it good for the price and others saying it takes setup and know-how.

Forty RGB-backlit buttons in an 8×5 grid — and Akai is unusually direct that they are buttons, not instruments. The FAQ states they are for launching clips and are not velocity sensitive, and the User Guide's spec table calls them clip-launch buttons outright. The sharper point is what is missing relative to the keyless sibling: Akai's own comparison table marks this unit as having no pad Note mode, no Drum mode and no Smart Scale, all of which the APC Mini MK2 gained. So the grid launches clips and stops there, and the keyboard is expected to do the playing. The one positive anyone offers is physical — the MK2's pads are larger than the MK1's. The criticisms are consistent: a reviewer flags the lack of velocity as a headline limitation, an owner finds the rubber buttons unimpressive, and a player comparing it to an MPK Mini notes they simply can't be played.

“The APC Key 25 is designed for Ableton, and the buttons are for triggering clips; they can't be played like the pads in the MPK Mini.”

The most closed part of the device, and the least disputed. There is exactly one socket: a USB-B port that carries MIDI and bus power. No 5-pin DIN, no CV or gate, no audio, no Bluetooth — and, contrary to a persistent assumption, no sustain-pedal jack either. Sustain is a momentary button on the panel. That the MK2 kept USB-B rather than moving to USB-C in a 2022 refresh was the detail the specialist press singled out. The upside of all this is real and worth stating: it is a one-cable device that needs no power supply.

“Interestingly, the new APC MIDI controllers don’t offer USB-C but a classic USB-B connection.”

Eight endless 360° knobs with four modes — volume, pan, send and device — switched from four Clip Stop buttons, plus dedicated play/pause, record and stop-all-clips transport keys and four navigation arrows. This is the half of the trade that goes the Key 25's way: its sibling has nine faders but no knobs and no transport at all, and buyers weighing the two cite the encoders and transport as the draw, reasoning that non-motorised faders get confusing once you can reassign what they do. In Device mode the knobs land on Live's eight Macro Controls automatically. Owners like how they feel. The gap a reviewer keeps returning to is expressive rather than mixing-related: there is no pitch wheel and no mod wheel anywhere on the unit.

“Instead of the faders, the APC Key 25 Mk2 offers eight rotary knobs for controlling volume, pan, send, or Device parameters as specified using the Knob Control buttons.”

“On the other hand, I like the APC Key 25 for having transport controls and Encoders instead of Faders.”

A real starter bundle and the least controversial thing about the unit. Ableton Live Lite leads it, and it is the piece that matters, since the controller is pre-mapped to Live and Live Lite is what makes that useful out of the box — the included Live Lite 11 also clears the controller's own 11.2.7-or-later requirement. Akai adds three AIR instruments: Hybrid 3, Mini Grand and Velvet. For at least one owner the licence is the single best reason to buy the thing. Worth knowing that this is a fact everyone restates rather than a claim anyone tests: no source assesses what the bundle is actually worth, and bundle contents drift over a product's life, so check what's current when you buy.

“I think biggest advantage is license for Ableton Lite that is provided with the gear.”

“Needless to say, both new controllers come pre-mapped to Ableton Live, so you can get started right away. A copy of Ableton Live Lite is included.”

Bag-friendly and bus-powered: one USB cable, no wall wart, and it goes in a rucksack next to a laptop. Calibrate the word, though — at 315 mm wide and 0.9 kg this is the larger of Akai's two mini APCs, and appreciably bigger than the keyless APC Mini MK2 it shares a price with. The keyboard costs it roughly 75 mm of width. Portable here means it travels easily, not that it disappears.

“These are portable and super affordable.”

“04:18 One cable setup”

Decent for the money, with a clear weak spot. The MK2's visible change is cosmetic — a modernised look with red sides and larger pads, in line with the current Akai family — and owners describe the knobs and pads as feeling good and solid, with one noting it responds reliably and feels high-quality overall. Against that, the most detailed English owner review is blunter: not super solid, and the rubber pushbuttons are the part that gives it away. Amazon's summary of its own reviews reports build quality as the most-mentioned strength. Treat it as well-made for $99 rather than robust in absolute terms — it's plastic, and it's priced like it.

“It is not super solid but it is doing it`s job. Definetly not Proffesional as it is writen :)”

GallAnnonymus · Thomann

“This also comes with a new, more modern design and larger pads.”
