Sample attributes not recognised by Kontakt 5


I’m using WE 8.

Tried to tag my samples with sample attributes (key, key range, velocity range).
While it works fine when importing to Halion 5 and the samples map correctly, Kontakt doesn’t seem to be able to read that data. The option “read sample metadata if possible” is checked.

Does anyone know what am I doing wrong or is it just not supported?
