The problem I had with firmware 1.09 and 1.10 seem to persist in 1.12
Changing settings in the midi info page still doesn't seem to work.
And although the checkmarks all are empty (and cannot be changed) the actual configuration is actually as initially set up way back around firmware 1.08.
I have been trying all day to get midi going from a device plugged into a usb host port I hadn't previously used.
After hours of troubleshooting I desperately rolled back to old firmware 1.08b3 and lo and behold, checkmarks appeared at the midi info page and moreover, I finallly could change the settings again.
Can anyone confirm this behaviour with firmware 1.12 of midi port input/output setting changes not being registered?
