C++ MIDI library.

• MIDI files read/write
• MIDI files parsing, editing, sequencing (composition)
• MIDI outputs
  • ALSA on Linux
  • WinMM on Windows
• Multiplatform MIDI players
  • synchronous
  • asynchronous

• Multiplatform (Linux, Windows)
• Endian safe
• Boost-like HPP header files only library

#include <cxxmidi/file.hpp>
#include <cxxmidi/output/default.hpp>
#include <cxxmidi/player/synchronous.hpp>

int main(int /*argc*/, char** /*argv*/) {
  cxxmidi::output::Default output;
  for (size_t i = 0; i < output.GetPortCount(); i++)
    std::cout << i << ": " << output.GetPortName(i) << std::endl;
  output.OpenPort(1);

  cxxmidi::File file("music/chopin.mid");

  cxxmidi::player::Synchronous player(&output);
  player.SetFile(&file);

  player.SetCallbackHeartbeat(
      [&]() { std::cout << player.CurrentTimePos().count() << std::endl; });

  player.Play();

• examples/callbacks Use of CxxMidi callbacks.
• examples/qtmidieditor Simple Qt GUI MIDI editor.
• examples/qtmidiplayer Simple Qt GUI MIDI player.
• examples/player_async Asynchronous MIDI player.
• examples/player_sync Synchronous MIDI player.
• examples/sequencing How to algorithmically create MIDI files.

To use library clone the repo and copy include directory into your project. Use of some cxxmidi classes requires external libraries linkage.

mkdir build
cd build
cmake ..
make
