Novation Launchkey MK4 Review: The Best Budget MIDI Controller?

By Marcus Chen · May 28, 2026

Overview

The Novation Launchkey MK4 series launched in early 2026 as a significant upgrade to the popular MK3 line. Available in 25, 37, 49, 61, and 88 key versions, the MK4 adds polyphonic aftertouch, a new chord mode, and significantly improved DAW integration.

Key Feel and Build Quality

The synth-action keys are responsive with a satisfying velocity curve that's customizable via Novation's Components software. The 49 and 61 versions feel noticeably better than the compact 25-key version. Build quality is solid for the price range — the chassis is rigid, knobs have good resistance, and pads are firm and responsive.

Pads and Controls

The 16 RGB pads are velocity and pressure sensitive, with excellent backlighting that syncs with Ableton Live's session view. The eight rotary encoders are infinite-rotation with LED rings showing current values. The pitch and mod wheels are full-size, a welcome change from the MK3's touch strips.

New Features Over MK3

Polyphonic aftertouch is the headline addition — rare at this price point. The new Scale mode locks keys to a selected scale, Chord mode triggers full chords with single fingers, and the arpeggiator has been expanded with mutate and randomize functions borrowed from the Circuit series.

DAW Integration

Ableton Live integration is the best in class — transport, mixer, device control, and session view all work out of the box. Logic Pro, Cubase, and Reaper also have dedicated mappings. FL Studio support remains limited, which is a drawback for that user base.

Verdict: 8.5/10

The Launchkey MK4 is the best all-around budget MIDI controller for Ableton Live users. The polyphonic aftertouch alone justifies the upgrade from MK3. If you use FL Studio, consider the Novation FLkey or Akai MPK series instead.
