Lag after a while
edited May 2022 in Support and Feedback
Hey @Michael - with my template project, after a good while of continuous use, hour-ish maybe, everything starts getting sluggish and laggy, even trying to open the app switcher to exit Loopy. After a refresh (go to power off screen-> hold Home) it returns to normal.
Project is not at max CPU, average is like 70%. Latest ipad pro.
Is this the fault of Loopy, or the ipad? Is it related to RAM/ memory? When I open Koala sampler in the proj, it says its received a memory warning.
I've got heaps of midi assignments, widget assignments etc. and I'm guessing it all takes up memory.
Any word on this @Michael ? Its a frequent issue, bothersome when playing live, and I'd just like a confirmation on whether its a memory thing or something else. It doesn't happen with the ipad otherwise so I'm guessing it has to do with Loopy.
Sorry about the delay! Playing catch up still after a week with the flu 🤒
Damn, that sounds annoying! Off the top of my head I can’t really say what it could be, I think I might need to see if I can reproduce that myself. Would you mind sharing your template with me and giving me an idea of how you’re using it typically? Then I’ll sit down for a while and try and reproduce it
Ah ok! Hope you're doing good
I've mailed you the project now. It'll happen just by having the project open with screen unlocked, in my experience.
I use it with an external audio interface connected, but that's probably not related.
Just let it run for like an hour maybe, and everything will get sluggish and laggy.
Great, thanks for that – I’ll give it a crack tomorrow
That is a staggering amount of plugins, though, @Icoustic – would you mind doing an isolation test for me? Make a copy of your project if necessary, and remove all of the effects - then try leaving it for an hour again and see if the lagginess still happens?
The lagginess could be LP, or it could be any one of those plugins, or a combination of any of them, so we've got our work cut out for us... But let's try to figure out if its LP on its own first.
Okay, an hour in here on my iPad Air 2 and no lag with your template – but I only have a tiny fraction of the plugins. Seems likely to be plugin-related.
Yeah, lots of plugins haha, but most are idle/ off though, not many active at the same time!
Try with clock running also, upon further testing I got lagginess after couple of hours with playback/ clock going - no loops though - and majority of plugins idle/ off (as they are when the project is opened).
I definitely wanna see how it goes with the plugins removed entirely, though, if you can manage that - just because they're in idle mode doesn't mean they're not running, it's just not calling into their audio systems.
Sure, I'm gonna test soon
So, as expected nothing happens when all plugins are deleted. CPU is 0-1%.
As I said initially, and have suggested in another thread, I was wondering if the issue is related to RAM/ memory since there's so many plugins loaded + a large amount of assignments/ mappings. Surely this all takes up memory,
and as I've mentioned earlier, Koala Sampler specifically gives me a memory warning when I open it in the project, as if there's not much memory left to go around.
And, ipad starts acting similarly in other instances where memory is low (way too many apps open, for example).
Haha thanks for the prod that spammer. Just realised I never replied to this, my apologies!
Yeah I’d say that sounds about right to me - that really is rather a lot going on there. We can only really find that out by experimentation, so try doing less and see if it resolves I guess.
With the new updates, it seems I'm no longer getting lags n hangs, also my ipads are getting considerably less hot!
I discovered a new bug after the latest, however - XY pads aren't functioning properly.
E.g. I have an XY mapped to a filter that worked fine previously, but now it doesn't move the parameters in the AU and the XY position reverts to the initial position upon release of the pad!
Both good and bad news! I can’t reproduce that XY pad issue – can you reproduce it on a brand-new project?
If so, what AUv3 is this happening with, or is it all of them? If not – could you email me your project?
Happens in a new project, I just tried with Fabfilter Volcano and ProQ, Moog Model 15 and Polyivoks filter, and all of them did it. XYs mapped to filter cutoffs and resos.
Ipad pro m1 & mini 6
Damn, I can't reproduce this at all - would you mind either giving me a step-by-step guide using Model 15 (which I happen to have installed), or send me a project with it?
There are no special steps, I just made a new project, set up Model 15 as effect on master, and assigned XY pad to it, reso and cutoff.
Hmm. I'm using the Audiobridge Trunk instead of Insert, but that shouldn't make much difference, eh.
Mailed you the project now
Ahh I see. It’s happening when the plug-in is idle or disabled. Okay, I think I can add a workaround for that
XY's default to hold-to-enable, right? Been using that.
It worked before the last updates, I didn't change anything.
I found that it works normally on my phone (iphone 11) even though its in idle mode (Model 15)
For now, I just switched off idle mode on those filter plugins, they don't need it anyway, I'm using the default hold-to-enable as mentioned, and stuff works as expected
Cool! I’ll be adding the workaround shortly anyway
