A 37-key slim-key USB-C controller at $149, built on the MiniLab 3's feature set. Hands-on reviewers broadly agree the extra octave makes it far more playable than the 25-key model, that Arturia's slim keys are among the best mini keys available, and that the regrouped 2×4 pads and shallower layout make it more comfortable to use. Integration is excellent with Arturia's own instruments and solid for basic DAW control, though Ableton-first users often point to Novation's Launchkey for deeper control. It stays light and bus-powered, and adds a real 5-pin MIDI out for hardware. Opinion splits on five things: the keys have no aftertouch (unlike Arturia's KeyStep 37 mk2), the pads have a few detractors, transport controls still live behind Shift and the screen is tiny, the plastic build reads as solid to some and cheap to others, and a minority see it as just a MiniLab 3 with an extra octave rather than a value win.
About this product
The 37-key MiniLab (June 2026; some retailers list it as 'MiniLab 37 mk3'): the MiniLab 3's feature set — eight RGB velocity/pressure pads, eight encoders, four faders, capacitive pitch/mod strips, a mini display with a clickable browse knob and a 5-pin MIDI out — on a three-octave slim keybed, with the pads regrouped 2×4 and a shallower chassis. Distinct from the 25-key MiniLab 3, the KeyStep 37 mk2 and the KeyLab Essential mk3.
Arturia's MiniLab 37 is exactly what its name suggests: the popular MiniLab 3 stretched from two octaves to three. Launched in June 2026 at $149, it keeps the 25-key model's slim keys, eight RGB pads, eight encoders, four faders, touch-strip pitch and mod, browse-knob display and 5-pin MIDI out, and uses the extra width to regroup the pads into a 2×4 block and make the whole unit shallower front to back.
The idea is to fix the one complaint MiniLab owners raised most — not enough room for two hands — without giving up the portability and the tight Analog Lab integration that made the line a default first controller. Reviewers largely agree it does that. The arguments are about what Arturia didn't change: no aftertouch on the keys, transport still hidden behind Shift, and a plastic build some find cheap.
