Status, November 2026: current. Novation still lists the Launchkey Mini 25 in its MK4 range.
What it is
The Launchkey Mini 25 MK4 is a USB MIDI controller for music software: it has no sounds of its own, and the bundled Novation Play instruments are what give it a voice. Novation announced the MK4 range in August 2024, per MusicRadar. It has 25 synth-style, velocity-sensitive mini keys, 16 RGB pads with velocity and polyphonic aftertouch, eight endless encoders, pitch and modulation touch strips and a 128 × 64 OLED display (Novation product page). Built in are a generative arpeggiator with a step editor, a Scale mode with 30 scales and three chord modes.
It is powered over USB-C and has a 3.5 mm TRS MIDI out for hardware synths and a 6.35 mm sustain input; it measures 338.5 × 176.8 × 49 mm and weighs 0.78 kg. The box holds the controller and a USB-C to USB-A cable, so a laptop with only USB-C ports needs another cable. The software bundle includes Ableton Live Lite, Cubase LE, Komplete 15 Select, Novation Play and Melodics lessons, and Novation's warranty runs 36 months.
Ableton Live recognises it automatically, while MusicTech found Logic and Cubase need a script download and some set-up. Reviewers and owners praise the pads and the chord tools; the most repeated complaint, from two reviews and five of the owners read at Thomann, is that the mini keys feel light or are harder to play than full-size keys.
