Play midi files via external midi devices or soft synth.
Playmidi is a web and curses and SDL-based MIDI file player for Linux and MacOS and Chrome (via Web MIDI and Web Audio apis). All recent development has moved to https://github.com/nlaredo/playmidi
It supports software rendering of midi files via SDL audio and can also output midi events to external midi devices (in time with SDL audio soft synth) via both alsa sequencer api (linux) and coremidi api (osx).
Math-based synthesis (when no sf2 is loaded and no external midi output is set) is planned to evolve over time to support most of the features found in a minimoog voyager, and wavetable based sf2 support is expected to evolve to properly emulate all the features of a roland sc88 (but not there yet).

Check out B-Step Sequencer too: http://b-step.monoplugs.com . A similar, new Project.
...It transparently handles conversions between time and pulses, tempo map handling etc. The only dependencies are C compiler and glib. Full API documentation and examples are included.
Note that the development has moved to https://github.com/nilsgey/libsmf.
Midi patch editor for Alesis Quadraverb GT effects processor. Runs under Windows. See the WIKI at https://sourceforge.net/apps/mediawiki/quadedit/. Now functional for most basic functions, needs work on: Midi Modulation, Multi-tap delays, sampling.
...The purpose of this library is not to make a big MIDI controller or synth out of an Arduino board, but to help you do it, the application remains yours.
