LK⁠.

Your Ableton Live remote. Your standalone MIDI studio.

Launch clips and ride the mixer in Ableton Live over Wi-Fi — or build tracks completely on your own. Six modules in one app: a clip-launching grid, pads, keys, chords, an XY pad, and a control surface you design yourself.

LK — Ableton Live remote and standalone MIDI studio
[ OVERVIEW ]

The short version.

LK turns your phone or tablet into a wireless Ableton Live controller — and a complete standalone sequencer for MIDI-compatible software.

A clip-launching grid, velocity pads, a build-it-yourself control surface, an XY pad, a chord generator and an expressive keyboard — six modules covering launching, drumming, mixing, chords and performance.

01 · What it is

Ableton's session view, in your hands⁠.

LK puts Live's Session View — and a full MIDI toolkit — on the phone or tablet you already own, wirelessly over Wi-Fi.

02 · What it does

Launch, play, perform⁠.

Fire clips and scenes, ride the mixer, finger-drum on pads, play keys and chords — or run it completely standalone as a MIDI sequencer for any app or hardware.

03 · Why it's different

A Live remote and a studio.

Six switchable modules in one app. Free to download — unlock only the modules you need, with no subscription, ever.

[ MODULES ]

Six modules, one app.

Each is a self-contained instrument
or controller — switch in a tap.
MIDI Pads module
02

Finger-drum with feel⁠.

A position-to-velocity pad grid for drums and one-shots, across multiple pages. Custom colours and labels per pad, three velocity-response modes, a tempo-synced arpeggiator, hold, and chord triggering.

VelocityPer-pad colourArpeggiatorChord trigger
Controller module
03

Build the controller you've always wanted.

A drag-and-drop surface of faders, knobs, buttons and encoders. Map any control to MIDI CC, notes, or Ableton device parameters — with multiple banks, MIDI Learn, and import/export of layouts.

Drag-and-dropMIDI LearnBanksCC · notes · devices
XY module
04

Moves you can't make with a knob⁠.

A pressure-sensitive XY pad controlling up to three parameters at once. CC or note mode, with a built-in tempo-syncable LFO and an attack / sustain / release envelope.

3 axes · X·Y·ZLFOEnvelopePitch-bend
Chorder module
05

Play chords like a pro, one finger at a time.

Trigger full chords from single notes, with key and scale awareness. An extensive chord library, a custom chord builder, savable presets, octave shift and a built-in arpeggiator.

Key + scaleChord libraryCustom builderArpeggiator
Keyboard module
06

A playable keyboard with real expression⁠.

Single or dual multi-touch keyboards with scale and root selection. Full MPE — per-note pressure and X/Y modulation — plus a built-in arpeggiator.

[ ANATOMY ]

Every pixel earns its place.

Designed for thumbs and stages —
nothing extra, nothing hidden.

Six modules, six full-screen instruments. Here's what each one does, control by control.

01 · Matrix

The whole session⁠, on one screen.

LK's Matrix shows the clip grid, scene launcher, mixer strip and transport at once. Tap a clip and it fires; drag the focus rectangle and Live follows. No digging, no menus.

In Live mode every element mirrors Ableton in real time — clip colours, scene names, track arm states. In MIDI mode the same grid becomes a standalone clip sequencer with its own piano-roll composer, no Live needed.

1
Clip launch grid

Tap to launch, double-tap to record. Live's clip colours come through unchanged.

2
Scene launcher

Fire a whole row at once. Long-press to queue without launching.

3
Mixer & transport

Always-on volume, meters and tap-tempo, staying in sync with Live's bar and beat.

4
Composer & clip tools

A built-in piano-roll with scale-aware melody and chord generation, mirror, transpose and follow actions.

Matrix module
02 · MIDI Pads

Pads that play how you press⁠.

A position-to-velocity pad grid for drums and one-shots, spanning the full note range across pages. Name and colour every pad, then latch them on with hold.

Press position becomes velocity — radial from the centre or linear top-to-bottom — so a single pad covers soft to hard without ever leaving the surface.

1
Velocity response

Radial or linear response maps where you press to how hard it hits.

2
Arpeggiator

Five modes, tempo sync, and adjustable steps, rate and gate.

3
Chord trigger

Play a full chord from a single pad, chosen from a deep chord library.

4
Live mode

Pads mirror the selected track's Drum Rack — pad names and all.

MIDI Pads module
03 · Controller

Every fader exactly where you want it⁠.

A blank canvas of knobs, sliders, buttons and pads. Drop in the controls you need, then drag to reposition and resize until the layout fits your hands and your track.

Save layouts across eight banks and carry them between devices — export a rig on your phone and import it on your tablet.

1
Drag-and-drop surface

Add, move and resize knobs, sliders, buttons and pads freely.

2
Eight banks

Give each bank its own layout; save, export and reload them.

3
Map anything

Send CC, notes or program change — or bind straight to Ableton device parameters.

4
MIDI Learn

Map external hardware to any control in a couple of taps.

Controller module
04 · XY

One finger, three parameters.

A pressure-sensitive pad that moves three destinations at once — X, Y and a Z axis driven by pressure. Assign them to CCs, notes or Ableton parameters.

A built-in LFO and envelope keep things moving after your finger stops, so a single gesture becomes an evolving modulation.

1
Three axes

X, Y and Z control up to three parameters simultaneously.

2
Built-in LFO

Sine, square or saw, tempo-syncable, with amount, rate and delay.

3
Z envelope

Attack, sustain and release shaping on the Z axis.

4
Release modes

Snap back to centre, fall to zero, or hold right where you left it.

XY module
05 · Chorder

Chords and strums, by touch⁠.

A honeycomb of chords laid out by key and scale — tap any cell for a full, in-key chord. Stack presets into layouts and build your own from an extensive chord library.

Strummers down each side let you play a chord's notes one at a time, like strings on a guitar.

1
Honeycomb grid

Trigger full chords from single cells, always in key and scale.

2
Guitar-style strum

Side strummers play the chord's notes like strings.

3
Chord & scale builder

A deep library plus a custom builder; save your own presets.

4
Arpeggiator

Five modes, tempo sync, and adjustable steps, rate and gate.

Chorder module
06 · Keyboard

Keys that bend to your touch.

One or two multi-touch keyboards with pitch and mod wheels, hold and panic. Pick a root and scale and the keys fold to show only notes that fit — so you never hit a wrong one.

Turn on MPE and every key responds to per-note pitch and X/Y expression, turning LK into a fully expressive MIDI controller.

1
One or two keyboards

Stacked layouts with pitch and mod wheels, hold and panic.

2
Scale folding

Choose a root and one of 20-plus scales; only in-key notes remain.

3
Full MPE

Per-note pitch and X/Y expression, right from the surface.

4
Arpeggiator

Five modes, tempo sync, and adjustable steps, rate and gate.
