Thanks. Now I have to find how I get these device nodes in MS Windows, as right now the code does not use these APIs AFAIK. For macOS it looks...

I'm revisiting this and am wondering: port_information already stores the MIDIObjectRef's UUID so you can get it back in the following way (typing this without access to macOS so likely...

hm but do we know for sure that the index of for (DWORD i = 0; SetupDiEnumDeviceInfo(deviceInfoSet, i, &deviceInfoData); ++i) is the same index than the one used by WinMM...

especially in "borderline" cases where we plug multiple identical MIDI devices which have historically been iffy in winmm
