I’ve realized that stems were less clean on my ipad pro (12.9’’, 5th generation, iOs 26.4.2) than on my macbook pro M1 Max (16’’, 2021).
I guess it’s for performance reasons. But what about using the latest iPad 13’’ M5, should I expect some differences too ? The stems processing performance is about the platform (macOs vs iOs) or the device performance ?
Hi @le3_dj, Neural Mix quality is hardware performance based not OS platform based. An M5 iPad 13 will run at 100% Neural Mix quality.
If that’s the case, why are 100% quality stems unavailable on high spec Windows machines?
Machines that will quite happily provide quality stems via VirtualDJ, Serato etc.
Hi @PKtheDJ, as you already know, 100% Neural Mix is available on Windows ARM-based devices. Our engineering team is looking into bringing 100% NM Quality to other high-end, non-ARM devices, but we don’t have a timeline for when this will be possible. Thanks!
Seems a bit brutally expensive having to upgrade to an M5 iPad for 100% stems quality. Especially given how powerful the M1 chip is anyway 
Surely we’re not already treating those devices as out of date and not usable?
@STU-C an M5 is not required to achieve 100% NM Quality. Just letting the user know that that specific device will support 100% NM Quality. It’s also possible with M1. Even my iPhone 15 Pro Max supports 100% NM Quality.
This old ipad pro I was talking about says however 100% Neural Mix Quality. How relevant is this percentage ?
The same percentage calculation is used on iPad and Mac. So if both devices say 100%, you have maximum Neural Mix quality on both devices. If you are hearing a difference in sound quality, then perhaps it’s from something else in your audio chain.
both macbook and ipad are USC-c connected to a Allen & Heath PX5, I’m using this sound interface. when I have time I’ll make an audio recording of the differences (I think) that are happening. Thanks for the follow !
even the iphone 2020 se provides 100% stems quality…
but the main difference is the heat thats generated on the iphone 2020se versus that of a m1 chip in a ipad…
but when one considers the comparative price of a 2nd hand iphone2020se & the portability of the tiny phone.. it just blows my mind 
Funny you mention the heat. I cracked the screen on my M4 ipad pro a few weeks back (dropped my phone on it), so i claimed on our house insurance and i got a brand new M5 ipad pro as a replacement. Anyway i decided to finally buy a folio case to keep the screen safe so it doesnt happen again. I was playing a game last night and the ipad was red hot after about 20 mins, so i had to take the case off and let it cool down, i could barely touch the back it was that hot.
Something for people to bear in mind when using Djay i would say, perhaps remove cases from your device to allow proper cooling.
i had a similar experience with the m1 ipad air… heating up…
this occurred when i updated the ipadOS from 18.x to the earlier versions of ipadOS 26.x… as the incremental updates rolled out, i retested til the heat aspect was sorted
the odd thing was… i wasnt pushing the ipad in any serious way, neither was i using djay pro when the heat issue occurred
so this told me, it was a IpadOS 26 beta bug that had not been ironed out
I will say that mine cooled down in a few minutes as soon as i removed the cover, i was quite impressed actually as it was pretty efficient at removing it.
Thanks for the additional info @le3_dj. An audio recording for comparison would be helpful. Before recording, please confirm the following:
