Novation 61SL MkIII vs Novation Launchkey 61 MK4

The Novation 61SL MkIII is the thread's top answer: the single most-upvoted reply (28 votes) in the r/ableton source thread named it outright. It's a studio hub, not just a keyboard: a Fatar semi-weighted keybed with aftertouch, five color LCD screens, and an internal 8-track polyphonic sequencer that can drive hardware synths directly.

Ableton worked with Novation on the Live integration specifically, and the SL MkIII adds HUI compatibility for Cubase, Pro Tools, Studio One and Reaper alongside deep Logic and Reason support. CV/gate outputs and a routable clock let it sit at the center of a rack of outboard synths, not just plugins.

None of that matters if you only open plugins: a producer who never touches the sequencer or CV/gate is paying for ports that sit idle. It runs roughly three times the budget pick's price, and its 100 reviews and 4.3 average are the thinnest and lowest of the three.

The Novation Launchkey 61 MK4 is the controller both source threads keep naming as the modern default, an all-in-one DAW controller built around 16 pads and a full control surface. It's for anyone who wants clip launching, finger drumming and mixer control without stepping up to Novation's sequencer-equipped SL line.

The 16 FSR pads carry polyphonic aftertouch, and 8 knobs plus 9 faders map automatically to Ableton, Logic, Cubase, Reason, Reaper and FL Studio through Novation's DAW scripts, with an OLED display showing the current chord. Scale Mode, Chord Mode and an arpeggiator are onboard, and at the time of writing it bundles Ableton Live Lite, Cubase LE and instruments from GForce, Klevgrand and Orchestral Tools.

The keybed is synth-action, not the aftertouch-equipped Fatar keybed on the step-up SL MkIII, and 182 reviews is thin next to the budget pick's thousands, since this generation just launched.
