## What is LK?

LK is a flexible remote control application for Ableton Live and MIDI devices, providing a wide range of features and functionality to enhance the production and live performance of electronic music. LK offers tight integration with Ableton Live using our free UBRIDGE desktop application, providing access and control of Ableton Live projects, with both wired and wireless connection options.

LK has extensive MIDI capabilities too, allowing for communication and control of any MIDI compliant software or hardware, even apps running on the same device thanks to virtual MIDI support and AUv3 integration too. LK is split into six unique modules, each available as a separate in-app purchase, offering great value that you can tailor to your specific needs.

LK is also capable of connecting with USB MIDI interfaces which allows you to interact with external gear.

To connect LK to your host computer you will need to download and install a free software utility called UBRIDGE on your computer. It is available for Windows and macOS and it can be downloaded from Imaginando website. See our setup guide for further details in LK’s product page.

MATRIX MODULE

- Live Mode - In Live mode, you can control almost every aspect of Ableton Live directly from LK. The app mirrors your session view, allowing you to launch clips, add tracks and scenes, arm, solo, and mute tracks, and adjust track monitoring, volume, pan, and cue settings on the master track. You can create and edit clips with the powerful built-in clip composer, featuring tools like scales, swing, humanize, horizontal and vertical mirroring, time-shifting notes, pitch swapping, transposing, and even chord and melody generation within a defined range. LK also enables device control within each track, offering a range of generic layouts for quick access and instant parameter adjustments, so you can modify settings without needing to interact directly with your computer.

- MIDI Mode - In MIDI mode, LK enhances workflow with a flexible, independent sequencing environment for streamlined composition and arrangement. Users can create and manage MIDI clips per track, arrange scenes, and send MIDI to other software or hardware. When loaded as an AUv3 in hosts like AUM, LK sequences and coordinates various instruments, perfect for complex setups and live performances. Essential editing tools like signatures, scales and transformative tools simplify MIDI editing, while automation and generative tools enable dynamic compositions. Follow actions and probability settings further smooth transitions, making performance arrangements seamless and spontaneous—all within a single, powerful interface.

PADS MODULE

- Get the MPC feel on your touchscreen with PADS, featuring an arpeggiator and a chorder. When working in Ableton Live mode it automatically maps drum rack pad names to each pad on the app - never miss a pad again. Use it in MIDI mode to quickly play other synth apps.

CONTROLLER MODULE

- Extensive control of 128 parameters with CONTROLLER. Use assignable and customisable knobs, faders, buttons and pads to control MIDI hardware, desktop and mobile DAWs - now with the power of AUv3 integration too.

X/Y MODULE

- Three dimensional parameter tweaking with X/Y PAD. This module can work with CC or NOTE events. In CC mode, a CC can be assigned per axis. In NOTE mode, X is pitch, Y is velocity and Z is Note ON/ Note OFF.

CHORDER MODULE

- Play chords like never before with the CHORDER module. Use this chord generator to build chords and lay them out according to your needs.

KEYBOARD MODULE

- KEYBOARD features 3-axis expression capabilities with scale and range controls. It also allows the possibility of mapping any Live or MIDI CC parameters to be controlled by the X and Y position within each of the keys, providing additional expression to the performance. It also has an MPE mode so you can use it with your favorite MPE compatible synths.

### 5/5 — Step Sequencer!!!!

*2026-08-20, version 1.16.0*

LK now has a step sequencer and it’s a pretty awesome step sequencer. I can’t believe some of the features it has right off the get-go. Probability and ratcheting, up to 64 steps, scales…etc. I used to primarily use LK along with AUM for clip launching, but now I’m gonna be using it with my modular gear too. Thanks guys.

### 2/5 — Too many bugs!

*2026-08-04*

This is my 5th and final installation of LK sadly. I love the Abketon Live format! Unstableness of the APP over time is one if the big problems. The worst though? Great difficulties in starting a new evenr, double clicking to open it! That, is the killer. 😔

### 5/5 — Le partenaire ultime de AUM

*2026-07-25*

J’utilise uniquement le module Matrix de LK, comme clip launcher et séquenceur dans AUM. Il m’a fallu quelques visionnages de vidéos YouTube pour bien comprendre comment l’utiliser ( la vidéo de Jamie Mallender est un must, plus celles faites directement par Imaginando , pour comprendre chaque nouvelle fonctionnalité). Et franchement c’est génialissime. Des tracks de clips, organisés par scènes. Un piano roll simple et efficace. Des follow actions. Des automations. 
Tout va pour le mieux !

### 1/5 — Asking for to purchase extras when recording live set!

*2026-07-05, version 1.15.10*

Asking to purchase extras in the middle of recording a live set when I’m logged in! I’ve already purchased what I want! Absolute joke!

### 1/5 — that‘s a kids toy

*2026-06-28*

The App is a kids toy and is not recommended for professional use. Until the app actually works, you have to restart the ubridge-app on the MacBook and the the LK-App on the iPhone what feels like 1000 times, which is pretty annoying. It‘s then up to chance wether the MIDI data from the controller is actually sent reliably. It would be a perfect tool in theory, but unfortunately it only works by chance, or not at all…so far just one star…

### 5/5 — Inexpensive, yet feature-laden!

*2026-06-11, version 1.15.4*

Inexpensive, yet feature-laden!

### 5/5 — Originally bought as Ableton controller, now an irreplaceable midi music making tool

*2026-03-30*

Like the title says I originally bought this to control Ableton, which it does, but what I didn’t expect I would be using so regularly, is the way it lets me compose music to send to various plugins and instruments, both software and hardware, from within something like AUM. I write the notes in LK and then decide which channels to send them too. I can also send multiple notes to the same channel and split them within LK to send separately within AUM.

It really is a beautiful experience to create notes with LK, and it also has automatic music generation and the ability to tweak existing notes slightly in new and random ways. This helps get me up and running more quickly too as I can just hit auto generate based on the notes specified, and LK generates either the chords or a melody which can then be sent to different outputs at once. Like for example I can run say a few different loops, like a drum pattern, a bass pattern, or a melody, all within the same window of LK, and have the basics of a full track up and running really quickly, and output it to different instruments, drum machines, or analog synths, or whatever really, without me having to spent ages on each element, or using multiple instances of another app to create and run the same amount of midi tracks sent to different instruments. Then I can go back later once everything is up and running and spent more time on what I need to.

There’s also lots of other features too like custom midi controller layouts, arps, and other useful things, all very capable of sending advanced controls to different locations. I used to use different instances of Drambo to send midi to my instruments, and occasionally still do, but compared to LK the process is just too basic as LK allows for more complex routing off the bat, and has a more elegant interface that allows for more flexibility making music. I really like this app and hope the updates keep coming as this is a very useful tool.

**Developer response:** This made our day, thank you. You've described exactly what LK is designed for: a single, flexible environment where you can compose, route, and perform without juggling multiple apps. The way you're using it across AUM with hardware and software instruments simultaneously is a great example of what the step sequencer and MIDI routing were built to enable. Really glad the auto-generation features are helping you move faster too, sometimes you just need a solid starting point to build from. Updates are definitely coming. Thanks for taking the time to write this.

### 1/5 — Missing tools and capabilities/ no refund

*2026-03-09, version 1.14.2*

The app is missing most of the tools that you may need for a digital midi controller. Even with the full purchase. You can’t just use it as a trusted tool. At the same time it is more expensive and does way less than most of its competitors! And at the same time they don’t accept refund requests! So you end up with useless expensive non refundable app. Search for better alternatives before falling for this.

### 5/5 — Enfin

*2026-02-20*

Enfin le contrôleur idéal. Tout essayer : Push, Launchpad, MPC40, xTouch, …
L’application est top. Réactive, accès distant, même les clips dans les tracks affichent le nom du clip. C’est vrai il faut un iPad mais pas forcément une bête de course et on peut en trouver sur le marché de l’occasion pour moins chère qu’un contrôleur physique. Bravo

**Developer response:** Merci beaucoup — ce genre de retour nous touche vraiment. Vous avez fait le tour des grandes références hardware, alors ça compte double. Bonne musique !

### 4/5 — Great for Ableton users!

*2026-02-11*

Awesome app, but needs a small tweak Fits my Ableton workflow like a charm! My only issue is accidental touches while scrolling. Adding a two-finger scroll mode would make the experience much smoother. Keep up the great work!

**Developer response:** Thank you for your feedback and the review! We've created a ticket for your suggestion so our team can evaluate it for a future update. We are so glad to hear you're enjoying LK!
