FFI wrapper for RtMidi ( http://www.music.mcgill.ca/~gary/rtmidi ) in Racket.
To compile, first extract
http://www.music.mcgill.ca/~gary/rtmidi/release/rtmidi-2.1.0.tar.gz to the
repository root. Then run make $PLATFORM, where PLATFORM is one of linux,
macosx, or windows.
The wrapper is C++98 and should compile with any modern C++ compiler.
I haven't tried the Windows build with this Makefile; you might need to make some adjustments.
See rtmidi-example.rkt to get started. Documentation and Racket package to
come.
