Novation FLkey 2 37

The short version

What to know.

A 37-key MIDI controller built specifically for FL Studio, around $230, with full-size synth-action keys, 16 RGB pads carrying velocity and polyphonic aftertouch, eight endless encoders, a 128×64 OLED, pitch and mod wheels, USB-C and a full-size 5-pin MIDI out. Sources agree on most of it: the FL Studio integration is the deepest available and needs no scripts installed, the move from fixed knobs to endless encoders removes the parameter jumps that plagued the first generation, the OLED finally puts chord names and parameter values on the hardware, the build is a step up from the Mk1, and the bundle — six months of FL Studio Producer Edition plus twenty-odd plugins — is generous if you don't already own the DAW. Two things divide opinion. The first is how dependable that integration has been in practice: reviewers describe it as faultless, while FL Studio owners spent part of July 2026 reporting crashes on the FLkey's transport buttons, which turned out to be a host regression fixed days later in FL Studio 26.1.3. The second is whether this size makes sense: $50 more buys the 49 with faders and semi-weighted keys, and Novation itself states the hardware is identical to the cheaper Launchkey 37 MK4. Note too that the keys have no aftertouch of any kind, there is no MIDI in, and outside FL Studio you are on Mackie HUI like everyone else.

About this product

The second-generation 37 — three octaves of full-size synth-action keys, 16 pads, eight endless encoders, an OLED, and no faders. Novation's own store lists it simply as "FLkey 37"; the user guide, downloads and every retailer call it FLkey 2 37 (FLKEY-2-37). Not the Mini 25 (mini keys, touch strips, 3.5mm MIDI out) and not the 49/61, whose semi-weighted keybeds, nine faders and keyboard zones are a different instrument. The 2022 FLkey 37 (USB-B, fixed pots, no screen) is still on sale while stocks last.

Novation's FLkey range is the odd one out in MIDI controllers: instead of shipping a template for every DAW, it is built with Image-Line for exactly one. The second generation landed in May 2026 with the two things owners of the 2022 original kept asking for — an OLED screen and endless encoders — plus USB-C, better pads and semi-weighted keys on the larger models.

The 37 is the middle-small option: full-size keys, the full pad and encoder complement, and none of the faders. Reviewers are close to unanimous that nothing else touches FL Studio this directly. Where they part company is over whether this size is the one to buy.

A good fit for

  • Producers who live in FL Studio and want the Channel Rack, Mixer and Patterns under their hands with zero setup
  • Newcomers without an FL Studio licence — the six-month Producer Edition licence and the plugin bundle are a real head start
  • Beat-makers who sequence and finger-drum on pads more than they play keys
  • Anyone who wants a full-size keybed and a real 5-pin MIDI out without going up to a 49-key footprint
  • Writers leaning on Scale mode, the three Chord modes and the arpeggiator to get ideas down quickly

Think twice if

  • You actually play parts: the semi-weighted keybed is a 49-and-61 feature, and this size keeps the synth-action bed
  • You want faders for mixing, or keyboard splits and layers — both start at the 49
  • You split your time across DAWs: outside FL Studio you're on Mackie HUI like everyone else, and the reason to pay the premium evaporates
  • You already own FL Studio — the bundle's headline item can't be activated on a machine that has had a licence installed, and the same hardware wears a Launchkey badge for less
  • You need aftertouch under your fingers on the keys, a MIDI in, or CV — none of them are here

The reviewer consensus

2 / 9topics divide opinion
4 Strong agreement3 Mostly agree2 Divided opinions

Common ground7

  • Nothing else controls FL Studio this directly: the Channel Rack, step sequencer, Mixer, Patterns and plugin parameters are pre-mapped, with no script to install
  • Endless encoders fix the first generation's biggest annoyance — knobs no longer jump a parameter when hardware and software positions disagree
  • The OLED finally puts chord names, parameter values and mode feedback on the hardware instead of your monitor

Points of contention2

  • How dependable the integration has been in practice: reviewers call it setup-free and faultless, while FL Studio owners hit transport-button crashes through July 2026 — a host regression in FL Studio 2026.1.2 that 26.1.3 fixed within days, but a reminder that a DAW-specific controller inherits that DAW's release problems
  • Whether this is the size to buy: one camp reads the range as fairly priced, while the reviewer who played across it argues $50 more gets you the 49 with faders and semi-weighted keys — and Novation's own FAQ says the hardware is identical to the cheaper Launchkey 37 MK4

Band: opinion spread · Dot: weighted average

The reason the product exists, and the one axis where the sources genuinely diverge. Reviewers are unanimous on depth: FL Studio detects it automatically, the pads drive the Channel Rack and step sequencer, the encoders map to the Mixer and plugin parameters, and there is nothing to install. Against that, FL Studio's own forum carried a run of reports in late July 2026 of the DAW crashing when the FLkey's Record, Undo or Redo buttons were pressed — reported independently on the Mini, the 37 and the 49. Reading the threads through, the cause was a host regression in FL Studio 2026.1.2 rather than the controller: Image-Line shipped 26.1.3 within days and both reporters confirmed it fixed. The durable lesson is the coupling itself — a controller this tightly bound to one DAW rises and falls with that DAW's release train. Outside FL Studio you get Mackie HUI and NKS, which every source describes as workable but ordinary.

Measured

Novation ships custom DAW scripts maintained with Image-Line; its spec sheet lists FL Studio 21.0.3 or later, while Image-Line's own FLkey 2 page states the controller requires FL Studio 2025 or later. Everything else runs over Mackie HUI (Novation names Pro Tools, Logic Pro, Cubase, Reaper and Studio One), plus NKS for two-way control of Native Instruments and NKS-ready plugins, and Novation Components for custom pad and encoder layouts.

vs. listeners — The crash reports are real but they are not a verdict on the hardware: they cluster on one FL Studio build (2026.1.2), affect other controllers on the same machines, and stopped with 26.1.3. Worth knowing anyway, because it is the flip side of buying a DAW-specific controller — and the two published minimum-version figures don't match each other either.

In practice it has been only as stable as the FL Studio build — transport buttons crashed the DAW until 26.1.324%

“When I press the record button on the FLKey MK2, it unexpectedly quits every time (so does my Komplete Kontrol s49 MK3). I don't have that problem with my Akai Fire or MPD 232.”

What to keep in mind 6

  1. This is a read of where opinion lands as of August 2026, and the FLkey 2 has only been on sale since May — three months is early for durability, QC patterns or long-term firmware behaviour to show up either way.

  2. The stability problems described here were traced to one FL Studio build and fixed in the next. If you're reading this much later, treat that episode as history rather than a warning about the hardware — but do keep FL Studio current, because this controller is only as good as the script running it.
