1. 5/5Massive W! One of the last ones of its kind but rightfully the best

   This is a ‘tailor made’ app for Ableton Live and it works exactly as advertised. I was one of the ones mad about having to purchase every feature separately but then it immediately made sense. They let you try every midi controllers to its fullest and gives you the option to buy it. This idea is godsend! You won’t find this specific behaviour in that many apps (I don’t know about a single one). Now let’s talk about the features. Let me just say I purchased each and every feature set they had to offer even though I only end up using only half of it. Why? Quality! Aaand maybe I wanted to support the developers seeing how approachable they are, willing to help every troubled users. And the app, well every single thing just works! Or do they? Well, like with every other midi controller apps, this one also suffers from the occasional hiccups when connecting to your computer for the first time. For example: I can’t connect mine wirelessly anymore even though I was able to before iOS 16 came out. Other than that, this as good as it gets. You have nothing to lose, download and try it! Buy if you like it. Simple as that. You won’t find another equivalent app that can top this. And the devs are actual human beings who will reach out and help you if you face any issues.

2. 3/5Good so far — please improve fader smoothness!

   LK as an iPad controller for Ableton Live is superb. The two-way control script works well and USB connection through UBRIDGE has been solid after I got over the initial setup (I found that some USB ports on my Windows computer would drop the connection to my iPad and so I had to try a few different ones). The big mark I have against LK right now is that, at least in Live mode, all of the faders and pots feel too choppy! It’s almost like the controls have less than the standard 7 bits of resolution, though I know this to be false since I can scroll through all 128 values of a macro if I move a control very slowly. But when moving a control with some speed, you get audible stepping when doing certain volume fades or filter sweeps, which is a shame. Controls in TouchOSC for example don’t suffer from this nearly as much. If fader smoothness improves in the future, LK will be a formidable live/DJ tool and get an instant five stars from me for the Matrix alone (plus bonus points if 14 bit control is added!). Some other suggestions: - support double tapping a control to reset to default value in Controller; - add a preference for “relative” fader controls a la TouchOSC, to prevent instantaneous parameter jumps; - on Windows, add a built-in virtual MIDI port to UBRIDGE to remove the need for a third-party MIDI routing app (the TouchOSC desktop app does this for example). Keep up the good work!

3. 5/5Love this app Need CC’s

   I’ve been using this app for a little while now and it is so useful. I mainly use the matrix for triggering notes in AUM. I have plenty of tools for automating and modulating CC’s like MLFO for example, but there are times when I just need to record CC’s from a midi controller. In this case, I end up needing to use Atom 2 for example. And if I’m going to use Atom 2 I almost feel like I don’t want to use yet another app like LK to sequence notes when I can already sequence notes and CC’s in Atom 2. I prefer the Ableton clip launching style that LK uses, but sometimes it’s just too many apps when I need to also automate CC’s. I love this app. I use it most of the time,.. but not all the time. Not when I’m really serious about recording my final mix. I would be ecstatic if this feature was added. You have a fantastic application here. It’s an (mostly) essential application for me.

4. 5/5Absolutely Incredible

   This app is magnificent. I am currently without any music-making hardware, so the MIDI keyboard and pads features are a godsend. The latency isn’t great over WiFi but with a simple usb connection from your iPhone/iPad to your computer it works beautifully. All the features of this app are amazing and I’m stoked to start working with it. I have a small iPhone so I might have to get an iPad just for this! The potential applications for live performance are already getting me excited. Perhaps the best part is the fact that you can pay for only the features you need, so you’re not buying a $20 app with a bunch of unnecessary stuff, depending on what you’re trying to do with it. Best music production-related app I’ve seen in a very long time, highly recommended.

5. 5/5Some errors but great software!

   ————————————- Update # 1 ——————- I guess my first review never went through! So my last one (the “original” I guess) seems as more of a complaint than anything else. Let me reassure you this is a fantastic plugin and is game changing for hosts like AUM or Ape. Especially on iPad. The iPhone mistakes will hopefully be addressed soon as pointed out on the response to my past review, by Imaginando. Consider purchasing this app if you‘ve always wished AUM, AudioBus or ApeMatrix had a more traditional “linear DAW” workflow and even more if you come from Ableton Live. ———————————————- “First” Review (after the real first one got deleted somehow): ———————- Dear Imaginando, please do consider turning your menus into scrollable. As a heads-up, on iPhone XS Max using ApeMatrix I cannot access many necessary parts of the software like the bar’s length simply because the menu doesn’t fit on screen and can’t be scrolled through. I know on iPad this might not be an issue but it’s a big one on phones, please do fix this ASAP as of right now it’s not as usable as it could be for iPhone users. Thanks and once again, brilliant plugin with some crucial errors (that hopefully will be fixed).

3. 5/5

   Failed to open on Android 16 / Samsung S23 FE. It didn't have this issue before updating from Android 15. \\ edit. Turns out if notifications are disabled, LK crashes / cannot run on Android 16.

   Yo lo uso para controlar los faders, knobs y pads en vivo y me ha sido muy útil. Es fácil de mapear y responde muy bien.
