There are plenty of new features in sfz:

- ogg-vorbis-compressed samples
- sample selection based on random values, aftertouch, host BPM, note 
sequence counter, previous key pressed, other key kept pressed or 
released, control change
- different triggers (trigger on release, first-in-chord/Hammond style, 
legato)
- more advanced exclusive groups
- random or CC-controlled note delay, sample offset, filter cutoff and 
perhaps others
- play sample N times
- beat syncing
- pitch randomization
- separate pitchbend config for "up" and "down" values
- 5 new filter types (LP6, HP6, HP12, BP6, BR6)
- stereo width control for stereo samples
- crossfading
- 3-band (looks like it's per-voice, but that would be quite CPU-intensive)

Also, it uses a "fixed" modulation structure instead of modulator 
objects, which may be a bit of a problem for Fluidsynth, or at least 
require a bit of thinking to convert it properly.

Looks rather tough.
