To use either of the FLUID soundfonts (gm or gs), comment out the default paths and uncomment either of the fluid lines in /usr/share/timidity/timidity.cfg. When using pulseaudio the use of timidity as a system wide daemon is discouraged, because both pulseaudio and timidity need the same device exclusively. However timidity can be started as a daemon for the user to provide the midi ports he/she needs for i.e. canorus. On the console of the user give the command: timidity -iAq -Oe -s 44100
