I am looking for an application that does just one thing:
converts REX2 files to ACID WAV **correctly**.

I mean "correctly" that REX2 slicing is perfectly converted to ACID WAV slicing, nothing else (as default ACID detection algorithm is pretty sloopy, to say the least, it requires lots of manual adjustment.)

An application already exists promising the REX2 -> ACID WAV conversion (will not name here, conisdered to be "industry standard" in sample conversion), but fails to do that correctly (not all slices are converted, random slices are in the resulting ACID WAV, etc.)

Do you know any app or solution that is able to convert and export REX2 to ACID WAV correctly?
