Are the packages 'timidity' and 'fluid-soundfont-gm' important?

Hello all,

I was reading this thread and ran 'dpkg --list | grep ^rc' out of curiosity to see what packages I hadn't properly purged. A load of kernel stuff came up (which I haven't actually removed myself) and also 'timidity' and 'fluid-soundfont-gm'

Are the latter two important? I re-installed them to try and get the sound working in a game I was having some bother with that is capable of using them, mostly out of curiosity, but nothing changed so I purged them again...

Are they important in the overall scheme of things? No.
Are they important for a select few programs to run properly? Yes.

Fair enough, I guess if they are needed for anything I'll find out in due course!

They're for playing MIDI sounds. Timidity allows you to use MIDI without a hardware synthesiser, and the other is a (one of many possibilities) sound font to say which sounds should be played for each MIDI instrument.
