簡單版：

#sudo apt-get install timidity++

#timidity filename.mid

複雜版：

Ubuntu下播放midi格式檔案方法:

1. Install timidity++

2. Get a soundfont, such as:

wget ftp://ftp.personalcopy.net/pub/Unison.sf2.gz

gunzip Unison.sf2.gz

有些軟波表是sfpack的格式需要安裝sfpack(windows下的程式，要用wine)

3. Add the following line to the bottom of /etc/timidity++/timidity.cfg

soundfont /"$sfpath"/Unison.sf2

4. timidity -Od "$file"
