iPad Pro midi keyboard stopper working

[Boven85]

Hello!

I have a 2018 ipad pro 12.9". Among other things I use it with my midi keyboard.

I have a usb-c to usb-c/usb-a/HDMI adapter, took it off ebay a few years ago. Everything worked great until a few days ago I updated to ios 15. Since then, my midi keyboard stopped working. When I connect it to the ipad using the adapter the keyboard turns on, but there is no sound being emitter when I play it, no matter the app (garage band or others).

All the pieces are working fine separately: the keyboard works when I connect it to the computer, the adapter works with the computer and even with the ipad when I connect it to my tv using HDMI.

I wonder if after the update the OS became picky about the non original adapter?

Any idea on what could be going on and how to fix it?

Thank you in advance!

I don't have an answer, but was hoping whether the issue was fixed? If yes, how?

no fix so far, the only answers I have gotten requires buying an official apple dongle
