libremidi

libremidi is a header-only cross-platform C++17 library for MIDI input and output.

This is a fork based on two libraries:

• RtMidi
• ModernMIDI

Instead of adding another abstraction layer like ModernMIDI does, this directly modernizes the RtMidi codebase with new C++ features and improvements:

• Callbacks are passed by std::function and generally simplified.
• Ability to use boost::small_vector to pass midi bytes instead of std::vector to reduce allocations.
• Less indirections, virtuals and memory allocations.
• Simplify usage of some functions, use C++ return style everywhere.
• Use of standard C++ snake_case.
• Use of standard C++ folder hierarchy ; just add the current folder to your include path.
• Simplification of exceptions.
• The library can be used header-only with the define LIBREMIDI_HEADER_ONLY.
• Passes clean through clang-tidy, clang analyzer, GCC -Wall -Wextra, etc etc.
• JACK support on Windows.
• JACK support through weakjack to allow runtime loading of JACK.

To-dos:

• Work-in-progress support for notification on device connection / disconnection (currently ALSA only)
• Work-in-progress support for UWP MIDI support on Windows
