Hi anand,
I believe that these files are created to make things a little easier, although I also think it would be interesting to have a configuration in YEM to determine which of these files will be generated so as not to have to delete those that are not necessary.
I find it very interesting to create a skeleton style with the loop slices in the right places, especially for those more complex drum grooves that would be difficult to sequence manually, as well as a multipad skeleton, although I almost always don't need the latter.
Regards,
Gabriel
