What are the steps starting from rebooting your device to get it into that state?
@soundsgoodbro
Are you on the LK beta list? We've released a new beta that tries to fix this freeze problem.
Can you please PM with your email so I can add you to the beta?
As for the others, were any of you able to replicate the freeze state with the new beta?
Re Beta build: Same problem here also.
My hardware MIDI controller still controls LK, but the interface is frozen or completely gone ...
If this happens, try getting your iPhone/iPad into the state where you see all open/recent apps and then dismiss it. That seems to fix things for me (got a a tip to try that from the developer).
you mean swiping up until all open apps are visible, then tapping elsewhere to go back to the app, but not actually closing AUM and restarting everything (which does nothing at all)P
Yes
Here are screenshots of what happens for me going from blank LK screen to fixed. Somehow forcing the device to show the recent apps list results in LK’s window updating. If it doesn’t work, do you have a reliable series of steps that gets you into the stuck state?
Really hard to reproduce. Restart iPad, open AUM, open project, use MIDI hardware controller to play project, change some notes WHILE project plays, freeze. Just now it even froze when trying to save but STILL PLAYED.
New iPad Pro 12.9, iOS 16.3.
in hot conversation with developers via testflight, nothing seems to work for me, also not the "bringing up the app overview" trick. i really hope they find the issue, since LK is an indispensable tool for me ...
I’m helping @xglax with debugging/testing this issue. I found something interesting. The freeze only happens if LK is in a midi strip as an AU midi processor in AUM. But if I use LK as an AU audio extension on an audio strip, it never freezes.
This works with the current App Store version too, not just the beta.
This is my workaround until it’s fixed. The Imaginando team (and their apps) rock! I’m sure they’ll figure it out.
Froze for me in AUM after a long while adding three tracks and manually adding notes for Klevgrand drums (Borsta*, Skaka* and Slammer*). Luckily I had just saved LK project so no biggie. iPad 11 M1 iOS 16.3 and latest LK beta 1.12.6(295)
I can close the window and AUM seem to work with the other track I have (guitar with loads of send fx).
*None of these has dedicated drum tracks.
Edit: I will try reezygle's method, I did not know you could do that
@reezygle: i had no idea you could do that and it makes no sense at all! : )))
but i will use this as a workaround for now.
thanks!
happy for a moment until ....
Did it crash or just fail to re-draw? If it failed to redraw, did you try the technique explained earlier to try to get it to redraw?
I'm thinking now that the complexity of LK is just too much to keep stable, selling all these modules under one roof inside one host which is itself hosted.
@imaginando: Why not extract MATRIX from LK, really really test/check the code and sell it as one app alternative to Xequence, the rock solid masterpiece of iOS sequencing ....
freeze in the sense of functions and reacts to MIDI controller, but window is empty. your redraw technique with "open ios app selector, pretend to look at apps, close again and check back with AUM" won't change things ... if i have understood it correctly that is
Have you tried redimensioning the LK window when it happens?
It works a few times for me. Also close and reopen the window (without unloading the plugin)…
Did you try it in the beta?
Trying the beta. Resizing, closing etc won't change the freeze in my case. trying different files, all the same. sometimes the interface freeze is still the matrix interface, sometimes it is gone and replaced by a brown screen.
this is just purepiano:
FYI: imaginando does not have recipient, it's either sinosoidal or xglax. Might have some more people active but those I don't know.
This is not correct. I get the exact same freeze as when I have LK in the midi slot, disappointingly enough.

@Pxlhg @henningz
are you able to send me a simple aum session that reproduces this problem? I have one session that reproduced, but while debugging it the freeze didn't happen. If we have more sessions to test maybe we find one easily reproducible in debug which will help a lot trying to fix this
Do you mean the actual AUM project?
It usually takes a while before it happens but doing stuff in LK back and fro (adding, moving or deleting notes, adding tracks or creating/editing automation) should suffice, it always is for me anyway.
I have not used LK in a long time before these sessions now and it's a lot of time wasted already but I'll see what I can do.
No promises though. 😊
It's such an awesome piece of software it's a real petty this isn't solved already (been a really long time now) although I do understand it's impossible to fix something you can't recreate.
Id be happy to send files @xglax. where to?
LK is an awesome software, but it needs to be completely stable to work in iOS music production and performance, such as AUM and iOS itself (and all other apps I work with ...).
You could zip it and attach it to a PM in this forum. The AUM project files are in the AUM folder visible in the Files app.
It would probably be useful to screen record a demonstration of the steps leading up to it and post it as an unlisted video and send them a link.
Here are some recent ideas with frequent crashes ...
What steps precede the crashes?
@henningz
I had this issue for a while and now it’s mostly stable for me with M1 as Imaginando had fixed it some time ago for my cases. I’ve noticed that it can still crashes (LK) when another AU crashes too: in my case mostly Xequence AU keys. Have you got some other AU crashing at the same time?
@xglax
For me it freezes when editing notes, as I say above. I doubt my project file will solve this but instead my iPad, which I will not send
I have a drum project with: Borsta(1), Slammer(3) and Skaka(2). Each have one dedicated LK Output(-). I start by pressing the triangle down right for the channel I want to edit and then, I just go about for a while till it freezes, which it will do, every time.
Last action will be stored which were not the case earlier when LK also frooze AUM (this was when the whole LK screen got browned out).
