It's the feel

SL MkIII boasts our finest and most playable synth-style semi-weighted keybed, with a sprung action tuned to the needs of the experienced player. It’s got aftertouch too, assignable to anything. Its exceptionally high scan rate of 10 kHz gives the keys a super dynamic feel for expressive performances. And you can see scales, modes and zones instantly with vibrant on-key RGB LED feedback.

SL MkIII's velocity-sensitive RGB pads have multiple functions too: they can be used for launching clips, as steps in the sequencer, for finger drumming, and have polyphonic aftertouch.

Keys for Live

We've worked with Ableton® to create an unprecedented integration with Live™. SL MkIII truly pulls your sessions out of the box. The full colour LCD screens give you full visibility of your parameters, while the pads, buttons, eight faders and eight knobs get you hands-on with your music - and in any major music software, using InControl.
