Akai MPC Key 37 G2 Review: Specs, Price, Key 37 and One G2 Compared

The MPC for players who think in chords. The Key 37 G2 puts the same 8-core engine as the new MPC One G2 inside a compact keyboard with 16 pads, wheels and aftertouch. Here is who it is for, and whether it is worth $999.

The Akai MPC Key 37 G2 is the second generation of Akai’s compact MPC keyboard. It launched on June 18, 2026 at $999, on the same day as the MPC One G2. Inside there is a new 8-core processor with four times the performance of the original Key 37, 4 GB of RAM, 64 GB of storage and a USB-C port that works as a 24-channel audio interface. Outside, it is a full MPC with 37 semi-weighted keys, 16 pads and a 7-inch touchscreen.

If you are deciding between this, the One G2 or the bigger MPC Live III, this review covers it. Comparing every model? See our best Akai MPC in 2026 guide.

What is the Akai MPC Key 37 G2?

The Key 37 G2 is a standalone MPC built into a keyboard. It runs Akai’s MPC3 operating system on its own: you can sample, chop, program drums on the pads, play plugin synths on the keys, record audio, arrange and mix a full song without a computer. Connected to a laptop, it becomes a MIDI keyboard, an MPC controller and a multichannel audio interface over one USB-C cable.

Akai’s pitch is simple: it is for producers and players who write on keys but want the focus of an MPC. The design keeps the original Key 37 concept, with a retro light-gray finish and the red Akai logo, a nod to the classic MPCs. Tefty Music Tech, who compared both side by side, points out a few small button changes, but the layout will feel familiar to Key 37 owners.

MPC Key 37 G2 specs

Four times the power, same engine as the One G2

The original Key 37 had one real weakness: power. With only 8 plugin tracks and 8 audio tracks, a full arrangement with a few synths ran out of room fast. The G2 changes that. It runs up to 32 plugin instruments and 16 stereo audio tracks at once, with up to 256 voices against 64 before. Those are the same track counts as the One G2 and the $1,699 Live III.

Practical Audio Lab sums it up well: the new CPU turns the Key 37 from a capable entry-level box into a machine that can carry real production sessions, in standalone mode or with a DAW. The 64 GB of storage also leaves room for big sample libraries and expansions.

Keys, pads and wheels: the reason to buy it

The 37 semi-weighted keys respond to velocity and aftertouch, and there are pitch and mod wheels on the left. That is what separates it from the One G2. Chords, basslines and synth leads feel natural, and you can play a part in one take instead of tapping notes into pads.

Above the keys sit the 16 RGB MPC pads, velocity- and pressure-sensitive, with 8 banks. So you still program drums and chop samples the classic MPC way. What you do not get are the new 3D MPCe pads, which Akai keeps for the Live III and MPC XL.

Two honest limits. The keys are a little shorter than a standard synth keyboard, closer to a good controller than to a piano. And the aftertouch is channel aftertouch (one value for the whole keyboard), not polyphonic. For hip hop chords and melodies, neither is a deal-breaker.

MPC 3.9 and the new synth engines

A keyboard MPC is only as good as its sounds, and this is where the G2 shines. It ships with MPC 3.9, which adds:

• MPC Oscillators: built-in synthesis with basic waves and advanced engines (FM, ring modulation and wavetable), so you can design sounds without loading a sample.
• Arrange Mode tools: cut, copy, paste and duplicate across a loop range, plus insert and delete bars, for finishing full songs on the device.
• Independent time signatures for each sequence and clip.
• Ableton Live control and project import, working together with the 24×24 USB-C audio.

The plugin bundle is bigger than on the One G2. Synth Anatomy lists 13 instrument plugins, among them Bassline, Electric, Fabric Select, Hype, Mellotron, Odyssey, Organ, Solina, Tubesynth, DrumSynth and the newer Jura (vintage Roland-style analog sounds) and Sub Factory (bass design), plus Native Instruments Analog Dreams MPC Edition and six expansion packs. For a producer who plays keys, that is a lot of instruments before you buy anything.

Sampling and connections

The back panel covers a small studio: two balanced ¼" line inputs and outputs, 5-pin MIDI in and out, eight CV/Gate outputs for modular and analog synths, an SD card slot, USB-A for drives and the new USB-C with 24 channels of audio in and out and 32 MIDI channels. Wi-Fi and Bluetooth 5 handle wireless.

One detail the One G2 does not have: a full-size ¼" headphone output, so studio headphones plug in without an adapter. There are no mic preamps or phono inputs, so vinyl needs a mixer or preamp and vocals need an interface. Thanks to USB-C, though, you can sample straight from a phone, tablet or computer with one cable. There is no battery: it lives on a desk or a stand.

The Pro Pack question

Like the One G2, the Key 37 G2 is compatible with Pro Stems, but stem separation, the Super Warp time-stretch and the Clip Matrix come with the optional MPC Pro Pack. Akai offers it at a 50% discount to registered owners. Audio News Room calls this the most cynical part of the G2 launch, since the hardware is clearly powerful enough. On the Live III and MPC XL, the Pro Pack is included.

MPC Key 37 G2 vs original MPC Key 37

The original Key 37 is still sold, around €739 in Europe in late 2026. If you only sketch ideas with a couple of synths, it can still be a good deal. If you want to finish full songs on the device, the G2’s four times the power and four times the track count are worth the difference.

MPC Key 37 G2 vs MPC One G2

This is the real decision for most buyers. Under the hood they are twins:

For $200 more, the Key 37 G2 adds the keyboard, wheels, aftertouch, a proper headphone jack and extra plugins. It also takes almost twice the desk space and twice the weight. Our rule: if your beats start from a chord, buy the Key 37 G2; if they start from a sample, buy the One G2. And if you want MPCe pads, battery and mic inputs, save for the Live III.

Pros and cons

Verdict: is the MPC Key 37 G2 worth it?

If you are a producer who plays, yes. The Key 37 G2 fixes the one thing that held the original back: power. Now it can run the synths, the drums and the audio tracks of a complete song on its own, with keys and pads on the same instrument. At $999, it is one of the most complete standalone production keyboards you can buy.

If you never touch a keyboard and live on sampling and swing, the One G2 gives you the same engine for less. But if your beats start from chords, melodies and basslines, this is the MPC we would choose. From a beatmaker’s point of view, it is the best way to get the MPC workflow and a real keyboard in one box.
