I have been considering an iPad upgrade from the Mini 2 to the 2017 iPad.....this sort of stuff makes me want to not bother and invest in something that works properly instead.

That Zoom R24 is looking more and more like a better investment by the day.

I’ve just sold my Pro 10.5. It feels good to be back on Air 2. Everything runs smoothly but I had to roll back to AB2. Now I have everything I need and will need for the foreseeable future. AB2 actually works quite well with AUM and presets recall perfectly. There is an issue of apps plugged into AUM only listening to host tempo changes but I’m simply saving AUMs tempo as an Audiobus preset and it just works. All in sync, super fast, all loading as intended, including Samplr and Loopy sessions. Bliss.

Ah, £500 aren’t burning my pocket either

I wish I heard more stories like this on a more frequent basis.....It IS a nice place to be when it works...but oh so frustrating when it does, then it doesn't, then it doesn't, then it does, then it doesn't LOL

Funny you should say that, for some reason Loopy is again not recalling the tempo when session loaded via Audiobus preset.

Michael knows about this so should all be good soon. Apparently it is picking up some random Link tempo.

I hope Loopy is misinterpreting Link Tempo in some way...if Link itself has problems we are doomed

I don’t actually use Link but Michael suggested the issue might be related to Link in one way or another. Not my field. Until the next version of Link with all start and stop command I’ll stay where I am.

In addition to Brambos' awesome battery thread, I just discovered that iPad Pro 10.5 and second gen Pro's have a setting to drop the 120 frame rate down to 60 fps. Although the display isn't as buttery smooth as it is with 120, it's definitely decreased my cpu by 4%. Might be useful for someone? Settings->Accessibility->Display Accommodations->Limit Frame Rate (ON)

Having said all those moany stuff about spikes and other whatnots I have to say that Audiobus state saving is absolutely fucking brilliant.

Being able to recall a song in a certain key and have that key and scale automagically load in voice fx rack for hard tune effect is mind blowing. People who work with hardware auto tune boxes have to bloody remember all that and set it manually before each song.

For me it is all soooooo close to perfection.

Thanks @Michael @j_liljedahl @brambos

Yes state saving, switching between apps, audio and midi, all those apps interconnexions and routing, AB remote is really what make Audiobus so essential some features are real genius!!

I confirm as in my previous post after my iPhone 7 Plus today’s session that hiding AB switching toolbar while performing AB/AUM/double loopy (universal + iPhone only) complex project at 128 buffers with Blueboard midi triggering was 100% glitches free and cpu usage was very stable too. Before that I had occasional pops (one per 30-60 seconds or even less) but sometimes I switched to 256 buffers to make clean live recordings. This « fix » allow for clean 128 buffers recordings and peace of mind.

Good point, disabling the 120fps helps quite a bit
Dragging the AU windows in AUM significantly causes DSP spikes too.

Audio Damage apps do use a lot of CPU and cause my apps go crash or have UI lag as well. I don’t use AUM but using Audio Damage effects such as EOS 2, or Replicant 2 causes BM3 to lag like crazy some times or even crash. I’m not sure why and the CPU usage increases drastically when they are used. Just something I’ve observed over time.

@Chris_Randall just tagging you so you're aware of this thread.

I’ve seen the same thing with GarageBand and Audio Damage effects. They work better in AUM: even if more cpu hungry than average AU, there are no stability issues despite strange Dubstation UI behavior which gives cpu spikes when closed and is stable when opened, like I said before in the thread. Audio Damage don’t do often updates, don’t know if we’ll see improvement here. Another « whole iOS thing » we have to live with.

Nope. Depends on who you buy from.

Didn’t mean all iOS devs don’t do updates, some of them really stand behind their apps. I wanted to mean that Audio Damage sound really good and have no real equivalent on iOS, but they don’t update their products so bugs persists and this is another frustrating thing with iOS, as we almost always have apps with issues here and there or whole iOS which need to be fixed.

This is an interesting page from the JUCE website, they are measuring audio quality on different devices in terms of latency and glitching......iPhone / iPad wiping the floor with android devices as expected, but the latency figures for the iPad pro's are interestingly higher than iPad Air and Mini 2

I just gave it a quick glance so correct me if I’m wrong. Yes you’re right Air 1 is definitely much glitchier than pros but Air 2 seems at roundabout the same level. My pro 10.5 was definitely more powerful but not as much as to vouch for its processing credentials. I could maybe run one, maybe two extra apps on it but that’s about it, and I’m not talking Model 15 kind of monsters.

I’m going to buy another pro when things get smooth software wise which I’m sure will happen at some point.

Thanks for sharing. I see Google Pixel 2 faring quite well...

Yeah Pixel 2 is a surprise...way ahead of the other Android devices....BUT, it does state that this does not take into account input latency, neither audio or MIDI...I was under the impression that Android was getting close to iOS in terms of output latency...but lagging (excuse the pun) in input latency, clearly it is still behind in both.

The 5th gen iPad is looking like not a bad choice based on raw audio performance...with your findings on the insignificant power increase with the Pro, and the fact it is less than half the price of a Pro would suggest it is probably the best value buy right now.

What I found most interesting was that the 12" and 10" pro's have 1-2 ms more latency than my iPad Mini 2 and the Air 1

All currently supported iOS devices (iPhone 5s and up, iPad Mini2/Air1 and up) are all rated suitable for professional musical performances.....just need iOS itself to not be messing this up

I'm really tired of reading/experiencing things like this and that's the reason i bought a newer macbook again 5-6 weeks ago.More than 5 years i was more or less fighting with all the quirks of every ios version (and i'm still on ios 10 on all devices),sucking up my creativity and the time i would love to put in music making instead.Not to mention the crappy midi sync with external gear.Finally I gave up and went back to Logic now.What a breeze and man...how much i missed this program.Everything "just works" (like back in the ol apple days),even when using 3 audio interfaces at once.It was a great ride on ios but the ipad is relegated to an external "hardware"fx studio unit (for) now.And some gadget fun every now and then

My appoholism was already cured quite a while ago

Just noticed iOS 11.2.5 is out... lets hope it will sort out some of the issues

They say it is final. Sounds kinda scary...and final!
