iOS 14.4.2 iPad Pro 2020 crackling Audio during preset switches

Hey guys... I had this problem now for months. Since I update to iOS 14.4.2. I have this issue.

I use AUM and when I load drambo in it and set instrument rack wavetable and wanna switch through all presets I got this ugly crackling audio.

Is there any fix for this?

 I tested it with an iPad Air with A14 Bionic... and there isn’t any crackling during preset switches. Same settings same iOS version.

    Is there some reason why you don't want to at least try 14.6? It may not fix the issue but at least would eliminate that as a possibility and put you on a version that more people with your model are likely to be able to test with.

  • Are you using an external audio interface?

    Indeed, updating to 14.6 is worth a try. iOS 14 has such a ridiculous history of issues on iPads used for audio production, it's not funny anymore.

    It also made the "Pro" models seem like the lower end iDevices for audio.

  • Yes there is a reason for not updating to iOS 14.6. Some old apps which I used for music production are might not work with new iOS version.

  • It would be good if the 'some old apps' was a bit more specified.

    I've got >300 music related apps installed on my iPad Air 2 (iPadOS14.6) and every single one of them works without any issues.

    The only 'issue' I had when installing 14.6 was with iOS Sound Canvas (which can no longer be purchased).

    I just had to re-download it from the AppStore to update it's certificate and voila, it launches and works again.

    (So if an app doesn't launch, a re-download usually solves the problem, especially if it's an older app).

    List the apps you 'worry' about and I can check (if I have them) if they still run properly...
