While I have a long line of experience with audio files, I think it is the context that threw me off. Here is a more specific scenario.
Another producer who works in Logic asked to send me his files, I know this may seem trivial but he said, "I am going to send you the stems." WHAT!?
Honestly, while the term is not autonomous to logic, I was put off by it because I was under the impression those files carried additional configurations that may not be suitable for importing into Cakewalk as apposed to importing general audio files.
I am assuming this is something that can be done right? Seems pretty straight forward, importing audio files as you have nicely explained.
