ModernMIDI brings together a number of support classes to read, manipulate, and generate MIDI data. For realtime input/output, the library gently wraps RtMidi for cross-platform hardware IO. Furthermore, ModernMIDI includes a comprehensive file io module for reading and writing format-0 files. Other features include common music theory concepts expessed in MIDI, along with a decently performing real-time file player. It's currently thin on the example/documentation front, but more samples will be forthcoming.
In various forms, it has been used in performances with the Seattle Symphony, installations at the Jewish Contemporary Museum in SF, and in many smaller Arduino prototypes in conjunction with HIDUINO.
This code is functional but rarely maintained. For a newer take on midi library support in C++, see RtMidi17.
To run the included exampes, use the included VS2013 or XCode 6 projects. ModernMIDI will build on any platform with a recent C++11 compiler. At present, ModernMIDI is not packaged into a static or dynamic library -- instead, the usage model is that developers will compile the small number of files directly into a new project.
ModernMIDI inherits from the linkage requirements of RtMidi. RtMidi needs a preprocessor macro defined in the project configuration to select the correct backend (e.g. __MACOSX_CORE__). On OSX the following frameworks must be included in a project: CoreAudio.framework, CoreMIDI.framework, and CoreFoundation.framework. On Windows, winmm.lib must be included although this is automatically handled in modernmidi.h.
ModernMIDI is a continuation of the functionality developed in LabMIDI by @meshula.
ModernMIDI is released under the simplified BSD 2-clause license. See the COPYING file for more information on the (license-compatible) third party code included within ModernMIDI.
