Recommendations for Device Optimization?
I know there's got to be plenty of threads here about this, but I'm wondering if there's one comprehensive post about it that someone can direct me to? (Device Optimization)
This scenario keeps playing out over and over for me. I'm using an iPad Air 2 (64GB):
Last night I'm playing around with Fieldscraper. Get a nice loop going. Add a chain in AB. Another chain has SP Link Edition going with a sustained background drone going. Another chain had Launchpad with some low background beats. Or the XK1 synth going through EchoPad. No more than 3 chains though, with each going into MiMix, levels for each set, then a 4th chain that's got another MiMix going into AudioShare to record.
All sounds good, other than occasional cracks and pops (not sure where those are coming from)
Then I add just one more FX to one of the chains. Maybe AUFX: Space. Sound good. Get ready to record, start playing either SP Link or the XK1 synth... hit record... then the whole thing comes tumbling down. No sound, locked up, have to quit out of everything, hard reboot, and start all over. All lost.
Am I trying to do too much for the iPad Air 2? Or, is this too much for AB? Or, are some of those apps buggy? Or, is my device not properly optimized for this stuff? If it's not optimized, is there a comprehensive list of things you can do to get your device stable enough to do something like I've outlined?
If this needs to be in another category, or if someone wants to direct me somewhere else, that's cool. Getty really frustrated after I finally start getting something I like, it all gets lost.
Comments
Probably the causes coincide with your concerns all-together.
The optimization so possible on I devices are quite scarce. Long story short: turn off anything that is not involved in what you are doing.
Short story long:
Activate airplane mode, turn off any kind of multitasking feature. Pretty short to be the long version but that is it.
Thanks. My iPad Air 2 is wifi only, so I didn't think to put it in Airplane mode. I'm not certain I had everything other than what I was using shut down either. Might have still had mail & Safari open. Doh! That's likely all it was. Thx!
@skiphunt hold down power until you see slide to power off. Then hold down power and home button until it takes you back to the home screen (approx 5 seconds) this resets the RAM and can fix a lot of issues with older devices. A lot of background apps never actually close which can cause short term memory leakage.
Do this ritually before starting a complicated signal flow in AB and it might save you from this headache. @skiphunt
Delete the facebook app :-)
Delete all non music apps
Other than the iPad Pro... I didn't think last year's iPad Air 2 would be considered an "older device"? They haven't even announced it's follow up yet. Or, are you speaking in general?
I have a feeling you might be right on this. Read recently that the Facebook app was reducing battery power by about 15% even if it wasn't open or being used. Ended up deleting it off the iPhone & just use Safari for Facebook now, but it's still on the iPad. I wonder what it's doing in the background even when it's not open? I'm sure tracking location. Not to get all "tin-foil-hat", but I wonder what else it's monitoring.
And as far as I know iOS 9.2 isn't helping at all
Switch off background app refresh.
Switch off Siri.
Switch off all notifications.
Switch off Handoff.
Switch off Gestures.
Switch off anything you can.
Restart as above every session.
Delete all non music apps.
Leave at least 5gb storage free.
If playing music or films off the cloud, sign out of iTunes to clear storage.
Sometimes, one restart is not enough to clear ram.
Well, I'm a visual artist photographer, so I won't be deleting all non-music apps off
but I bet there are plenty of other apps I never or rarely use that could be killed.
I've only got about 3GB free, so it's likely time to clear off all of those recent Bolivia/Peru raw photos.
Didn't know you could turn off Siri, gestures, handoff, etc. Will look into that. I rarely use most of that stuff.
Good comprehensive list. Thanks!
By the way, I did everything @Fruitbat1919 @mschenkel.it @TheMaestro and @yaknepper suggested to my 64GB wifi iPad Air 2, and I can't believe the difference. I'd taken all of that for granted I guess.
I then went and did all the same things to my lowly iPhone5, ran 4 chains with one running DAW Multitrack playing back 3 mixed tracks that I did with Fieldscraper, routed into AB with 3 more chains for Launchpad with FX, XK1 synth with FX to play while 3 track DAW mix playing.. all routed through 4 instances of MiMix and then recorded to AudioShare.
All in all, over a 6min soundscape. Didn't get a single freeze, crash, crackle or pop. Solid all the way to the end.
Thanks again. I can now get back to playing.
Great to hear that. Maybe I should do the same to my ipad2.
@skiphunt I was speaking I general. I read wrong too. I thought it was air one. Turn off spotlight search. That's huge for brand new iPad mini4. iOS 9 archives the shit out of everything with Siri and spotlight. Turn those two off, turn off multi gestures, and use that trick if you still run into troubles. It's a problem with iOS 9.
I got a HUGE improvement by just doing what was listed above... not only on the iPad Air2 but also on my old iPhone5 and I didn't even turn off Spotlight and Gestures.
Always wished Apple would make a customizable state... where you could leave all the bells and whistles on if you want, but if you knew you were getting ready to do some video or audio editing/production, you could flip your custom state switch and all this stuff would be turned off at once.
I did the same for my iPad Mini 2. But I didn't bother to compare performance before and after. I haven't had any issues either. But I'm all about getting more performance regardless. Glad it made a difference for you.
@Fruitbat1919 Thanks for the tips!
I'd just purchased a few new apps and was taking time to get familiar with them last night, so I knew all I was trying to do when it failed. It was easy to go back and try exactly the same thing after I'd followed all the recommendations and the difference was night and day. And not just on the iPad Air2, but on a beat up iPhone5 as well.
Honestly didn't think the iPhone5 was even capable of that much with regard to audio, but after following all the suggestions in this thread to optimize, it held up just as well as the iPad.
That reminds me, I should do the same for my iPhone 4s. I have Gadget installed and was surprised that it even played some of the demo songs. But it started choking while I was tweaking one of the synths while it was playing. So I should be able to get more done on the iPhone and then continue those projects with the iPad as needed. More than likely, I won't do much with the iPhone because of the size. But it's good to have Gadget installed and the phone optimized just incase.
@skiphunt glad to hear your workflow is now uninterrupted:). I know how annoying that can be.

Didn't know that one. Thanks @Fruitbat1919 !
Some very useful recommendations in this thread! I just wanted to add that you can do a reboot by holding down the Home button and Power button together and keep them down until you see the apple logo on a blank page (about 15-20 seconds?). I have been looking at my CPU usage constantly today using an app called "SystemMonitor" and it has been sitting at 40% minimum the whole time, with nothing else running. I tried holding down the home button then power+home trick mentioned above but it didn't fix it. Only after the reboot (presumably turning it off & on again would do the same) does my CPU now idle in the single figures. I don't know what caused the CPU spike but I will watch out for it again now!
Update on this thread for the year 2020! Please
