About this app

ATTENTION: LK is a controller application and it doesn't produce sound. If you are looking for a playable app on your mobile, search for DRC instead.

LK is a sophisticated remote controller application for music software and hardware, featuring a tight integration with Ableton Live. Easy customisation with 4 independent modules, intuitive use, creative tools and ways to control or compose makes LK a powerful companion for any electronic musician.

See what’s inside:

- Control almost every aspect on Ableton Live, from composition to automation, clips, tracks, devices and much more with MATRIX.

- Get the MPC feel on your touchscreen with MIDI PADS, featuring an arpeggiator and chorder. This module works in two modes: Ableton Live and MIDI mode. When working in Ableton Live mode it automatically maps drum rack pads names to each pad on the app. You will never miss a pad again.

- Extensive control through 128 parameters with MIDI Controller. Just like MIDI PADS, this module works in either MIDI or Ableton Live mode. Forget the old school MIDI mapping. In Ableton Live mode, with the learn function you just need to choose assign and change the parameter… ready to rock!

- Three dimensional parameter tweaking with X/Y PAD. Just like MIDI PADS and MIDI CONTROLLER this module also works in either MIDI or Ableton Live mode making it to assign parameters on the fly with the learn function.

- Play chords like you have nevel played before with the CHORDER module. Just like the other modules, it works in Live or MIDI mode. Use the chorder generator to build your chords and lay them out according to your needs.

- Keyboard module serves as a Live or MIDI enhanced keyboard controller with 3-axis expression capabilities. It is fully customisable to scale and keyboard range. It also allows the possibility of mapping any Live or MIDI CC parameters to be controlled by the position you play in each of the keys of the keyboard thus providing additional expression to the performance of each note.

The ability to connect USB MIDI interfaces allows you to interact with external gear at the same time you control Ableton Live since you can switch modes on the fly at any time.

To connect LK to your host computer you will need to download and install a software utility called UBRIDGE on your computer. It is available for Windows and OSX.

Love the different scales and that you can record midi tracks. Not sure there is another app like it. My main issue is that the metronome in midi mode is broken. It is not synced up to the track and therefore pretty useless. Also wish they didn't nickle and dime you for every feature. Edit: Compared the metronome to the one on the ipad app (that works fine btw) and it seems the issue is not the metronome but the matrix timeline is what's running the wrong time.

It's functionality was intermittent, would lose connection randomly and occasionally not show up in Live, using the same settings. I stopped using based on poor functionality. One star rating for bad programming, even with "let LK run in the background" unchecked, it always runs in the background and gives me alerts when I've accidentally launched. GREAT JOB! That alone is worth removing it from my phone and life.

This app is incredible. I think what bothers people is that they piecemeal out all the different components when they should really just sell the full app and call it done. Each segment is incredibly useful. I love how you can switch between scales and turn certain midi notes on and off. Incredible feature. The Midi Chord pad concept is BAR NONE the coolest midi tool ive used and I have yet to find anything that's comparable. I certainly hope they keep this app alive! It deserves to be nurtured and developed, honestly a phenomenal tool which turns even the most basic tablet into a valuable resource for music producers. Not to mention the UI looks so space age in my rig! Right out of star trek. Great job guys, I've been using this for years.
