What kind of keyboard are you using? It would help to know that. I haven't made any changes to the MIDI functionality on iOS (it's all going through coreMIDI) other than adding an new setting to reset the network MIDI session for users that need that. So for it to suddenly stop working for you is incredibly strange. I would be very curious to hear if backing up your library (Settings->Backup and Restore->Backup Library), uninstalling, reinstalling and restoring your library backup resolves the issue. The fact that you have some things working and not others makes it hard to identify where the problem might be. If you go to Settings->MIDI Settings->Configure MIDI Connection, can you verify that both the input and output ports are checked for your keyboard?

Thanks,
Mike

Thanks for replying Mike. Before I read your reply I backed up the library. Deleted MS, reloaded the app. and restored the library. Unfortunately the issue still exists. The keyboard is a SX900. I’ve double checked Midi settings in MS and on the keyboard. Keyboard ALLPARTS and System Exclusive is checked for both transmit and receive. I also checked with a Midi snooper on my Ipad to check that the System Exclusive message is being received and verified the same data is being seen by MS when linking with a particular registration. I also have tried both midi ports from the keyboard USB and MIDI din with a Midi USB adaptor. Both give the same results. As I say it’s been working flawlessly up until now. I wonder if it’s an IOS update issue or a problem with my IPad.
