The Sonatina Symphonic Orchestra is one of the best free orchestral sample libraries available, but it is shipped in SFZ/wav format. The free SFZ plugin from cakewalk does not let you adjust attack/release and finding an alternative is frustrating, at best.
Soundfonts, on the other hand, have widespread support, a bajillion different plugins for playing them and in general are my preferred format. So, I converted the entirety of SSO to .sf2 format. I figure this might be useful to anyone else who likes soundfonts, so I have zipped them up for you. Each instrument is an individual SF2 file, since I find large soundfont banks rather unwieldy.
