Amazing, this is exactly the kind of thing I happened to be looking around for this week. I'm sure I can reason it out but would you mind adding macOS steps to the readme? I notice you marked an issue about macOS compilation as completed so I assume it works?
Nice! yes IEMidi is cross platform and works on macOS, but i haven't gotten the time to finalize the Packaging for that system yet, but extremely glad it works right out of the box on your macOS.
Edit: Yes yes yes this is awesome, thank you!
