You misunderstand - I'm talking about the Microsoft MIDI API for Universal Windows Platform (UWP) applications (https://docs.microsoft.com/en-us/windows...amera/midi). I'm not talking about Windows, which has different drivers and APIs for communicating with MIDI devices. Other applications have access to APIs for MIDI that don't have the same limitations as the C# UWP library Microsoft has made available for store applications. I'm not the first developer to have issues with their UWP MIDI library, but Microsoft doesn't seem to be addressing any of the issues. That is why I'm going to have to read the raw USB MIDI data myself and process the MIDI messages back and forth (this is what I currently do on Android). This all would be a lot easier if I could use any of the open source or commercial libraries for communicating with MIDI devices, but none of those are supported for UWP store applications.
