right when you're ready to save the new sound you created to the subdirectory in the hard drive you should look at your sound location number(for example.1-25) then choose the same location(1-25)in the drive by scrolling down to that location then save it.
there is an easier way to locate the location youre looking for by typing it's number rather than scrolling down,if you need more info an this let me know.
