Novation Launchkey 49 MK4 vs Novation Launchkey Mini 25 MK4

The Novation Launchkey 49 MK4 is the modern form of the thread's most-named answer, "Novation Launchkey MK3" scored 8 upvotes as the generic recommendation, and the line has since moved to MK4. 49 keys and the same in-depth Session View mapping as the rest of the family make it the one most producers should actually buy.

The semi-weighted keybed is a real step up from the Mini's mini keys, still synth-style but with more resistance and better dynamics for playing parts rather than just triggering loops. The 16 polyphonic aftertouch pads carry over unchanged, along with Scale Mode, Chord Modes, an editable arpeggiator and an OLED chord readout, and it ships with Ableton Live Lite, Cubase LE and Melodics at the time of writing.

It's still a plastic-bodied controller at this price, not a premium build. There's no built-in sequencer or CV/Gate output, so it only talks to software, and 49 keys is still short of a full range if you're coming from an 88-key piano.

The Novation Launchkey Mini 25 MK4 is the pick for anyone who wants real Ableton control without carrying a full keyboard. It's Novation's cheapest current Launchkey, and the r/ableton thread behind this guide leans hard toward the brand even when its single top answer was the larger SL MkIII.

16 RGB pads with polyphonic aftertouch double as clip launchers, a step sequencer and chord triggers, and they mirror Session View's colors so you can see what's armed without touching the mouse. Scale Mode keeps every key in the right key, three Chord Modes trigger full progressions from one pad, and the box includes Ableton Live Lite, Novation Play and free Melodics lessons at the time of writing.

The keybed is the tradeoff: 25 mini keys are synth-action, not a real piano feel, and two octaves is tight for wide left-hand movement. There's no screen, so chord and scale feedback lives on pad LEDs alone, and you'll outgrow it fast once you want to play parts with both hands.
