The SoundFont 2 reader of LoopCraft's loopcraft-audiofile crate (sf2.rs at
storytold/loopcraft@0d150c1), over a neutral model of its own: the sample
pool, presets and resolved key/velocity regions with tuning, loop points,
pan, gain and volume envelope. The fixture writer its tests use is the
test-support feature, so readers in other crates can test with real files.
