Open sound forge, or any other software that creates sustaining loops, create a sustaining loop, save the sample.
Open in any software that is up to date, loop point is found, this includes Kontakt.
Open in Maschine, the loop is not found, but Maschine does support importing loops, older samples that saved the sustain loop to an unofficial chunk will open and have their sustain loop set in the sample editor.
Maschine needs to support the current official sustain loop chunk in the meta data of a wav file, Kontakt does.
It is also worth noting that creating a sustain loop in Maschine and then using save sample as, does not save the sustain loop, so as of right now, Maschine supports sustain loops, supports loading sustain loops, but there is no way to create them, because all other software has long since been updated to support official sustain loop chunk creation.
