Orpheus 2 Soundfont Exclusive [patched] -

Most SoundFonts in the early 2000s used single-layer samples (one sample pitched across the keyboard). The Orpheus 2 Exclusive used three or four velocity layers for critical instruments like piano, strings, and snare drum. This meant that when you hit a MIDI note softly, you heard a softly played sample , not just a quiet loud sample. For a file under 100MB (a miracle then), this was audio sorcery.
