I have a soft maple tree that has some of the leaves turning black with holes in them. I can't see any bugs or anything. Any ideas what it is or what I can do? I have other hard maple trees with no leaf problems.

Sounds like "Tar Spot" to me. Here is a link from Purdue University regarding symptoms and control.
