Redux SFZ capabilities

Hey, what are SFZ importing capabilities of Renoise and Redux? Multiple layers are obvious, I noticed round robin too. Is there more? Thanks.

So far I only used virtual synths, but recently I also started to play more with these sample based instruments. Seems to eat less CPU power than a synth algorithm, (and I can discover a whole new world of sounds when I am playing with the wave files). :blush:

So, I am also curious about the main differences between all those formats, and whether it is advised to keep certain steps in mind when I want to preserve the exact behavior of the original instrument when importing it into Renoise.
