Are there any other alternatives aside Timidity?
Vazhavandan’s suggestion looks good, but as he says, it’s more of a workaround rather than a solution.
Besides, I’ve installed Timidity before, back on openSUSE 12.2 in order to make music to work on Doomsday (playing Ultimate Doom, for example), but music tracks played with quite a different tone in comparison with Windows, as though they were a “remastered” or a different version, and it was not the same. I think it was probably because of Timidity…
