Don’t know if it’s possible. I think the browser would benefits from a expandable tree to view samples (like .xrni and .xrns files do)that are listed by a .sfz mapping, (even if the actual audio files must be nearby,) and only load a certain sample with it’s own keycenter settings etc…
In sfz’s term, this is listing every single of the .sfz and just load a selected one, which contains a sample and it’s own properties.
