Progress Report: WPF, C# and .NET
Having created MIDI Generator in Python and built executables using PyInstaller, I thought it might be worth exploring other languages and environments. While this approach yielded workable versions for both Windows and MacOS, the app runs less-than-snappy. Also, I still envision additional features, several of which are under development presently.
AutomaticMIDI, which will be the successor to MIDI Generator, saw several weeks as a Dart/Flutter app and another in Processing/Java; the latest (and, so far, best) version is a .NET WPF app written in C#.
