Polyphonic aftertouch on full-size keys, 16 RGB pads, 9 faders, and the deepest Ableton integration available — the Launchkey 37 MK4 is the best controller under £200.
| Keys | 37 full-size velocity-sensitive keys |
| Aftertouch | Polyphonic (per-note) |
| Pads | 16 velocity-sensitive RGB pads |
| Controls | 8 knobs, 9 faders |
| Connection | USB-C bus-powered |

Polyphonic aftertouch allows individual notes in a chord to respond differently to additional key pressure. Press harder on one note and only that note modulates. On compatible instruments this unlocks expressive performances that standard controllers cannot achieve. Previously found only on instruments costing ten times as much.
Novation and Ableton have a long partnership. The 16 pads map directly to Ableton session view clip slots. Faders control mixer channels. Transport and navigation work without MIDI mapping. If you use Ableton Live, this controller is custom-built for your workflow.
The MK4 generation is a significant step up: better keys, brighter pads, more professional fader action. The overall construction feels premium for £179.
The first choice for Ableton Live users who want a controller that does everything. The polyphonic aftertouch makes it compelling even outside Ableton. 37 keys is the sweet spot — enough range without an unmanageable footprint.
The Novation Launchkey 37 MK4 is the best MIDI controller under £200, and it's not close. Polyphonic aftertouch at this price is extraordinary, Ableton integration is class-leading. If you use Ableton Live, this is the controller you want.
