Midi stopped working with iOS 15.4

I reported first issue when get it on 15.4, in march 27, and I’ve sent a lot of logs and a lot of new information to them. I really don’t know why is so difficult to fix that.

Thanks, unfortunately my Piano doesn't have 5-Pin DIN midi connectors, only USB Type B. I was looking at similar devices that convert USB Midi to Bluetooth but reluctant to spend more money to fix a problem that Apple shouldn't have created in the first place. I've reported the issue here: Feedback - iPad - Apple. Let's hope Apple fix this in the next update!

I have to call them and they will do a live diagnostic while I run the apps. I'll update here after the call.

Here is my reply to Apple:

- Names of other MIDI apps that you said are affected

       - Simply Piano 

       - MIDIWrench

       - Synth One

       - Midi Sheet Music

       - MIDITrail

- Exactly what external hardware are you using including the brand and model info from the cable, external MIDI controller, etc.

        - Yamaha YPG-235

        - Yamaha NP-V60

- What software or firmware versions are you on (if devices that have onboard control and use SW/FW).

              - The keyboard I have uses internal driver and is plug and play and so are most of the keyboards mentioned in this forum: https://discussions.apple.com/thread/253771323?answerId=257431253022 There are a lot of other people that are having the same issue. 

I will call the support number and do the live diagnostics

A lot of app allow users to manage different midi keyboard with iPad for example Camelot Pro, cubasis, Sampletank etc. Irig midi Is a workaround but not the solution. Also if u have a soundcard with standard midi the result Is the same of using irig.

Yes, the package comes with the USB-A to USB-B cable and the USB to Bluetooth adaptor. On one side of the adaptor is a standard USB-A plug which needs to be pushed in to a standard USB 5v wall charger, then on the other side is a USB-A socket which the included cable plugs into.

just stopped working for me today. Was playing on my Yamaha-125W, went for a break, came back, plugged in my iphone 12 pro and got “device is not supported”. I’ve been using SimplyPiano for 6 months without issues. Today just stopped working without any changes.

Yeah, its a third party brand USB-B to lightning that has been working fine for 6 months. Out of the blue in between piano sessions it stopped being recognized and after replugging it a couple times the unsupported message popped up.

In the meanwhile, I found out that it is somehow related with the connected USB devices. I use a rather old Yamaha P-250 Stage Piano via USB. With this, none of the apps that try to scan for Midi devices, work anymore. If I use the iRig Midi interface and connect the Piano via DIN midi cable, everything works fine. With a new Midi Keyboard (Nektar GX 61), I still can use the direct USB connection. The problem might be related with older Midi standards.

Hi. Are you using a Din to USB cable? Is it that. I have a piano and it has the two interfaces. The USB-B and Din. I don’t have the Din cables, and I was using the USB-B to USB-A connected in an USB-C Apple adapter. If I connected a Din USB cable instead of an USB-B USB-A cable, do you think it will work?

I will need to buy it. :-(

Thank you.

I do not use these simple „cables“. For sure they contain more or less the same interface chipsets like the iRig MIDI interface. I can only say, that this is a functional work around for my setup. As the „cables“ are pretty cheap, I would recommend you to try it. Might be quicker as a bugfix by Apple.

Man, just found out this doesn't work with my Yamaha CP33. All my music apps crash now: Ravenscroft, Korg Module, Sunrizer, etc.. And I have a concert tomorrow. Gotta find another solution. Come on, Apple!

Do you work with iPad or iPhone?

Which models do you work with?

You know

I solve my problem, i just change the keyboard, my 17 y. old Yamaha for a new Casio oxygen 61 m-audio.

It works for me also with a Yamaha P-125 B

And also update my iPad Pro 2017, iPhone 11 to iOS 15.4.1

And everything, all apps I have are working just fine

God look!

(I think that in the new iOS update is not included the old MIDI system)

Yep. No midi apps work on my brand new IPad. Connecting to a Yamaha CP4, all apps crash. I could get one app working with an old Oxygen 49 controller. Strangely, I have Ravenscroft on my phone which is the same iOS version, and that works fine (except not usable because Apple removed the headphone jack). 🙄

I have important news to report. I was able to get the iPad to see the MoXf again. After the update suddenly I believe my midi adapter the Yamaha UX96 went unresponsive. I replaced it with an IRIG2 and suddenly the iPad sees the Moxf again. I hope this helps everyone. I can't tell you how much pain I went through the last 24 hours trying to get it to work. I found out that other Yamaha Moxf owners still had a working midi connection after the update which made me take a second look and start replacing parts just in case.
