Doesn't IOException mean the next provider is to be checked?

That is the IOException could be handled in the iterator, its code may need to be updated for that. Then the implementations of `getSoundbank(URL)` could propagate the IOException too and eliminate duplicate code.

`InvalidMidiDataException` isn't caught there, so the iterator code should handle it.
