It kind of depends. I started my computer-aided music making with Loops using Acid software, the early software that made "looping" a thing available for the desktop set.

Loops in general, if the software is right, can have their pitch changed and time compressed/expanded. I think most loops are rhythmical in nature, but that might also contain some pitch information in short, repeating musical phrases that "loop" end to beginning in a rhythmical pattern.


I'm not familiar with the loops available from PGMusic enough to know for certain how they are handled within BiaB. Certainly Rhythmical loops will match tempo, and will change pitch if there is pitch to be changed.
