By aspect — in detail
Sources split on emphasis. Judged against the MK3, the redesigned mini keybed is widely called a real step up — more responsive, better-weighted, closer to Arturia's mini keys. Judged against full-size keys, it's still 25 cramped mini keys over two octaves, fine for sketching but a stretch for real playing. Velocity-sensitive; no key aftertouch. Chord and Scale modes now play on the keys, not just the pads.

Spec: 25 velocity-sensitive mini keys with a newly redesigned keybed, spanning two octaves via octave up/down buttons; no key aftertouch.

A genuine improvement — the most convincing mini keybed Akai has made44%
“The keys are more pleasant, the action more responsive, the bounce better measured, and the overall feel much more pleasing than the MK3.”

Still cramped two-octave mini keys — not for two-handed or piano playing56%
“Mini keys can feel pretty cramped.”
MusicRadar
Still the series' signature strength. The eight RGB-backlit MPC-style pads (two banks, velocity- and pressure-sensitive) are widely called the best finger-drumming pads at this size, and slightly more responsive than the MK3's. Two caveats keep it from a clean sweep: the pads are physically a touch smaller this generation, and at least one owner reported a unit that couldn't reach full velocity — the usual reminder to try a controller's pads in person.
“If your workflow revolves around finger drumming, these pads are the best you’ll find on a controller this size.”
SoundGuys
“MPC-style drum pads are as playable as ever.”
MusicRadar
“the pads seem slightly more responsive than those of the previous model, with better detection of keystroke nuances”
Audiofanzine
“The pads on my unit would be impossible to strike at full velocity”

Headlined by the biggest change of the generation: the MK3's four-way joystick is replaced by dedicated pitch and modulation wheels, which reviewers unanimously prefer — the pitch wheel springs back to centre, the mod wheel stays put. New dedicated transport controls (Play/Stop/Record/Loop) and a full-colour display with its own encoder round out the surface. The recurring gripes: there are no faders for mixing, and the wheels themselves are small and plastic-feeling to some.
“The pitch wheel has a nice bit of resistance and automatically returns to the middle position when I let go”
MusicRadar
“The new wheels behave much more like those on a traditional synthesizer.”
SoundGuys
“The absence of faders, on the other hand, may frustrate some live or live-automation-oriented users.”
Audiofanzine
“the mod wheel is small and plastic feeling but much better than a touch strip”

Integration
Contested · 7 srcSources split, roughly evenly. Akai supplies deep DAW control scripts (Ableton, Logic, GarageBand, FL Studio, Cubase) with 1-to-1 screen feedback, and for many reviewers everything worked smoothly once configured. Others hit real setup friction: transport controls dead on the first plug-in, a Windows driver that Windows Defender flags and that can crash DAWs, no Studio Instrument Collection automation at launch (confirmed by Akai support), a clumsy Ableton track-arming mapping, and no script for Studio One. There is no AAX support, so the bundled instrument won't load inside Pro Tools.
Measured
Akai supplies DAW control scripts for Ableton Live, Logic Pro, GarageBand, FL Studio and Cubase (no Studio One); the hardware is otherwise class-compliant USB-MIDI. A separate MIDI driver is required for the DAW/plugin control ports — on Windows it can be blocked by Defender's driver protections until those are relaxed.

Comprehensive native DAW support — smooth once it's set up
“the Akai MPK Mini IV has native support for Ableton Live, FL Studio, Logic Pro, Cubase, and Bitwig Studio.”

Fiddly and buggy out of the box — expect setup work and driver snags
“the transport controls, which don’t work for me straight out of the box.”
MusicRadar
A generous, more modern bundle than the MK3's. The headline is the new Studio Instrument Collection — one plugin holding 1,000+ presets from AIR, Moog and Akai, pre-mapped to the eight knobs — alongside Ableton Live Lite 12 and trials of Melodics and Splice. Reviewers rate the sounds highly and see it as a complete starter studio. Caveats: it's VST3/AU/standalone only (no AAX, so no Pro Tools), DAW automation of it wasn't supported at launch, and at least one owner argued rival bundles (Novation's Launchkey) offer more.
“The heart of the offering is now the Studio Instrument Collection, a unique virtual instrument featuring over 1000 sounds from AIR, Akai Pro and Moog.”

“This bundle effectively turns the controller into a complete starter studio.”

Connectivity
Strong consensus · 4 srcThe most consequential upgrade, and a near-universal win. Where the MK3 was strictly USB-only, the IV adds a real 5-pin DIN MIDI output alongside USB-C, so it can drive hardware synths, drum machines and modules directly — bringing it level with rivals like the Arturia MiniLab 3. A 1/4-inch sustain input remains. The only knocks are minor: there's no MIDI in, and Akai still omits an on/off switch.
“the addition of a true MIDI Out port profoundly changes the nature of the MPK Mini IV.”
Audiofanzine
“With MIDI Out, the MPK Mini IV can now control external hardware synthesizers or drum machines, which makes it more useful in hybrid studio setups.”
SoundGuys
Measured
Rear I/O: USB-C (class-compliant, bus-powered), a 5-pin DIN MIDI output, and a 1/4-inch sustain-pedal input — the MK3 had only USB-B and sustain. No MIDI in; no power switch.
Portability
Strong consensus · 5 srcStill the whole point, and still a strength. About 347 × 192 × 46 mm and roughly 1 kg (2.3 lb), bus-powered over USB-C, it drops into a backpack or onto a cluttered desk. It's a touch larger and heavier than the MK3, but the difference is small and the nomadic character is intact.
“It fits easily into a backpack, slips onto a cluttered desk and is well-suited for a portable setup.”
Audiofanzine
“the small footprint means you can carry it, work anywhere, set up quick.”

All-plastic, and read as solid-for-the-price rather than premium. Most reviewers find it well put together and not fragile, though the plastic chassis disappoints a few, one outlet rated build the weakest of its scorecard, and a forum owner noted slight play in some knobs. A recurring, honest caveat: long-term durability is still unproven on a controller this new.
“While its long-term durability remains to be verified, it doesn’t appear fragile.”
Audiofanzine
“It’s lightweight (just over two pounds), under 14 inches wide, and still feels solid, not plasticky.”
IDJNOW
Rarely disputed at around $99: real upgrades (wheels, MIDI out, USB-C, colour screen) and a big software bundle for sub-$100, which reviewers repeatedly call one of the best options at the price. The one dissent is competitive — an owner argued Novation's Launchkey Mini offers a stronger bundle and chord features for similar money — so the value case is 'best-in-class if this format suits you' rather than uncontested.
“If you’re looking for a great MIDI controller below the $/£100 mark, it’s hard to look past this as one of the best options out there.”
MusicRadar
“the Akai MPK Mini IV remains one of the best MIDI controllers available.”
SoundGuys
“doesn’t look to be good value compared to Launchkey. Launchkey comes with 4 great Gforce synth vsts, Komplete Select and the chords features are better on it.”
