Midi stopped working with iOS 15.4

I think they stopped supporting certain midi devices and if that is the case I will throw my iPad in the garbage and go get a Samsung. They suggested I update my Clavininova which I could do a firmware update, but that update was a long time ago and I suspect it wouldn’t resolve the problem anyway. Apparently Yamaha is talking to Apple about a solution.

I am also very disappointed. Apple removed the headphone port and now the USB MIDI connection. It is true that MIDI DIN works fine but there are features on my Yamaha MO8 that only work with usb MIDI (DAW MIDI Control for example).

This happened to me too, but I think I managed to find a (temporary?) solution (sorry if this posted already). TLDR: it seems to be working again once I switched to Apple's original Apple Lightning to USB3 Camera Adapter (link to Amazon).

My setup is a Casio keyboard, the latest iPad (2021) and SimplyPiano. I was using this (link to Amazon) USB + charger splitter/adapter, and it worked great with both charing and the USB cable for midi from my keyboard. Yet, post iPadOs upgrade the USB part stopped working, still charging well. I then tried a few different USB to Lightning adapters, but none worked. As a last resort I tried purchasing the original Apple one. And voila, that one is working. For now.

As an information. I've updated my Yamaha Calvinova to latest build and it didn’t work.

The app crash when it’s opened while connected thru usb-b usb-a and adapter. It’s a bug on iOS/iPadOS. No doubt about that. :-(

Same problem here iPad Pro suddenly stopped working with Yamaha keyboards. The older cellphone still works, but is a major pain to use with music. Certainly, neither device will be replaced with an Apple device as long as this problem persists. Apple seems to have lost the “It just works.” motto. Over to you, Apple.

Hi, I think the problem is with the latest version of iOS. Here‘s why: I have a 2011 MacBook Pro running OS X 10.12 and an old version of GarageBand. This works just fine with my Yamaha P155 (vintage 2011). My iPad and iPhone are on ios 15.5. GarageBand worked very briefly with the Yamaha on both the phone and the tablet and then didn‘t. I reset both the iPad and the phone. Again, after about 5 minutes, GarageBand didn‘t recognise the input. I also have an old Android

phone. Just for the heck of it, I downloaded a freebie app (Piano MIDI) from google play and tried that too. It worked!

So please apple, fix your iOS midi bug!

I have a support agent from Apple helping me, they open the case and said for me to send them screen video. They said in seven days the developers will review the issue and my case rep will get back to me.

I guess they don’t read the forums since she said this has not been reported. I’ll keep y’all posted.

I asked for support to apple and they recommended a full reset of my iPad in order to test but the problem exists in iPadOS out of the box, so I asked to SimplyPiano for support, they said that they know about the issue but, "Apple have to fix something in their end"

That’s funny. So I reset my iPad today as apple suggested and right after the reset it worked with simply piano. After coming back a few hours later it stopped working. Simply also told me the same, it’s on the OS side. I asked apple to refund me the full subscription amount I’d they can’t fix the issue since I only bought the iPad for leaning music. Let’s all keep at it

I saw the same behavior with my iPhone 12: After reinstalling simplypiano it worked, just before I restored purchase of the subscription, then did not work, I think this is reproducible. So this means, the problem is not related to drivers.

That’s interesting. It worked for me after the restoring the purchase. I used it for about 30 min also. I come back later and it stopped working. If it was simply piano they would do a quick release since this all they do but I think it’s on the OS side.

So I got an update from apple. I told them that it’s happening to all the midi apps I tried, over 10, and her dev team told her it is most likely an OS issue. She said she will update me in a few days to confirm and let me know when what iOS version they will release the fix. I’ll keep y’all posted, my iPad is pretty much useless unless I can use it for music

Finally, after doing all apple asked to do in order to escalate the problem, in a support call, they recognized that the problem is in their end and there are no solution time, the only alternative we have is to wait...

What really gets me is that they are acting like they didn't know about this issue 2 months ago. It had been reported to them then, but your comments indicate that they are acting like they didn't and that they just now escalated it to that level....I have to tell our app's customers that they just can't use it with older Yamaha keyboards right now until Apple fixes it, which is not great for any business model.
