TiMidity++ is a software synthesizer. It can play MIDI files by converting
them into PCM waveform data or other various audio file formats.
TiMidity++ can also be run as an ALSA sequencer client. To do this, make
/etc/rc.d/rc.timidity executable and add this line to /etc/rc.d/rc.local:
/etc/rc.d/rc.timidity start
Optional dependencies are jack, speex, and portaudio.
You will need a set of instrument patch files or soundbank fonts for
TiMidity++ to be of any use. Install freepats, eawpats, or fluid-soundfont
(or any combination of these) to satisfy this dependency.
