The WinRT MIDI api in latest Windows 10 returns the name "MIDI" for some devices, which have a different name with the Win32 MIDI API.
For example the RME HDSPe AIO has a port name "AIO Midi" in Win32 API but just "MIDI" in WinRT API.
Is there any fix for this? Or a way to relate Win32 API midi ports to the WinRT counterpart?

2022-06-06T13:29:06.137+00:00 I'm porting an app from the Win32 MIDI api to the new WinRT MIDI api using WinRT/C++ for the ability to detect MIDI device hotplugging
Its not a UWP or WPF app

2022-06-07T03:02:26.087+00:00 Could you try to use the MIDI API and get the same MIDI device in UWP applications to check if it has the same behavior?

2022-06-09T13:34:21.503+00:00 Yes the issue is present in the UWP MIDI sample from microsoft here - https://github.com/microsoft/Windows-universal-samples/tree/main/Samples/MIDI
There are devices list as just "MIDI", even though an application like MIDI-OX (http://www.midiox.com/) has the correct name

2022-06-23T08:06:03.543+00:00 Could you please submit a feedback about the MIDI APIs in the Feedback Hub? You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. The team could check the feedback and confirm the behavior.
Currently, we suggest using the win32 MID API if your feature relies on the MIDI port names.

2022-06-24T16:23:27.233+00:00 My application needs to support hotplug detection of MIDI devices, hence the WinRT requirement. Win32 MIDI is unfortunately not an option.
