I have the old Pro 12.9 and the 10.5. Noticeable performance difference when using Auria etc.

Not sure how discernible between 9.7 and 10.5 Pros.
Screen real estate is prime though.
Its the same big performance increment, altmost double in multicore:

What about the latency, do you play in realtime with it (amps, effects, synths)?
Well I have bitten so I will see what happens.

I use Bias FX live and it’s fine - I don’t notice the latency.
Auria is used to record our rehearsals live.
Have a few Midi synths - again , they work fine, I’m not good enough to hear the latency.

I finally received the Ipad Pro 10.5 256 gb tested it with several music apps and the results are totally amazing. Fortunately it came with IOS 10.3.
Its my number 4 Ipad and its the first time that I feel that all that Apple cpu hype is real, finally it can be compared with a real computer.
Normally with my previous Ipads, even the latest pro 9.7 128 gb I had the feeling that the power of the cpu was very limited, it was enough to use a Bias or Pod or Yonac guitar processor at the same time as Midi Guitar and some synth to finish listening soon clicks and unwanted noises.
Now, finally, things seem to have changed, a lot:
in a test I had 4 synthesizers at the same time, Alchemy (inside garageband) + Module + Photophore + Magellan, all playing simultaneously with Midi Guitar in addition to processing the guitar with Bias FX or Pod and not a single click pop or suspicious noise and all at the lowest latency (64 samples)
Im really surprised and amazed this time.

Should you desire to maintain that low latency , speedy performance,I  suggest avoid upgrading to IOS 11

Yes of course im avoiding it in my Iphone and Ipad.
But Apple insists hammering again and again, despite the fact that I have deactivated the warnings and that I delete the IOS 11 update file every time as you suggestetd.
Its very frustrating that every time the update window jumps in front of my screen, a simple touch in the wrong place and goodbye, it will be irremediably updated. Very scary!.
Not to mention the fact that the programmed obsolescence in the Apple ecosystem is one of the fastest: soon the programs and accessories are not compatible with previous versions of IOS as it happens in some updates of my programs that I could not install due to that only supported IOS 11.

None of the proposed solutions really solves the problem, the only thing would be the one that implies the blocking of the domain in the router, although it is a little heavy and does not solve the problem when the device connects to other Wi-Fi networks, but maybe I will do it anyway in my house, because I am so tired about.
What would happen when I share my Iphone inet connection with my Ipad? it will eat all my GB?  ::)

IOS 11 is perfectly tuned for audio apps. Even Cubasis was upgraded and with real time Waves plugins, unavailable with other OS releases before.

Have you used it with low latency apps like amp sims, Midi Guitar, synths etc?
Please comment your experience.
There are many people interested to know.

On Monday Apple AAPL +0.57% released iOS 11.2.2, its most important update for some time, but it seems in the rush to upgrade some users are encountering a very nasty surprise indeed…

‘Great Secret Features’ and ‘Nasty Surprises’ are my regular columns investigating the best features / biggest problems hidden behind the headlines.

Apple
Apple iOS 11.2.2

For a number of iPhone owners iOS 11.2.2 is throttling performance by as much as 50%. I exclusively picked up on this trend in my iOS 11.2.2 Upgrade Guide yesterday as users were not just subjectively reporting their iPhones and iPads felt slower, but being able to demonstrate it with before and after benchmark scores (1, 2, 3, 4, 5, etc).


I was subsequently contacted by tech developer Melvin Mughal who, having read my Guide, decided to document a detailed breakdown of how his iPhone 6 performed before and after updating to iOS 11.2.2. For him the impact was dramatic.

Across over 30 single-core and multi-core benchmarks, Mughal found single-core and multi-core performance of his iPhone 6 fell by an average of 41% and 39% after updating to iOS 11.2.2. The results are broken down on his blog. It is worth pointing out Mughal upgrade to iOS 11.2.2 from iOS 11.1.2 not iOS 11.2.1, but that shouldn't be relevant as the throttling Apple introduced in iOS 11.2 was specifically for the iPhone 7 only.


iPhone performance before and after updating to iOS 11.2.2

Instead the obvious finger to point is at the sole feature of iOS 11.2.2: mitigations for the serious Spectre vulnerability which is impacting just about every platform around the world. Apple even warned users in advance the patch could have a performance impact in some situations, but said it was not expected to be higher than 2.5% in any situation. So are the big drops the consequence of an error in these mitigations or a problem elsewhere in the update?

Furthermore there is a flipside to this story with some users actively reporting benchmark performance increases after updating to iOS 11.2.2 (1, 2, 3), though admittedly these were fewer in number and run counter to Apple’s own warning. Personally I’ve found no difference to the benchmark scores of my own iPhone X and I’m sure that’s the same for many others, but it doesn’t help those who have clearly been very badly affected.

I’ve reached out to Apple for a comment on this and will update should I receive a reply.

Ultimately new cases of performance degradation are the last thing Apple needs in the midst of its iPhone battery debacle. All of which pushes extra pressure on the mysterious iOS 11.2.5…
