Note.
THFont sucks absolute shit. It is terrible and is not a direct rip of the SD-series; it is only a cheap imitation created in a group effort to emulate the sound, but it's still nowhere close. Using soundfonts in general won't get you the sounds you get straight from the source, the MIDI hardware itself provides much, much better everything over using a soundfont. And before you ask, "ripping" the sounds itself from the SD series is illegal, which is why it's come to this in the first place.
But if you're okay with a free soundfont then whatever.
