Which languages, if any, outside of Semitic have something like Semitic-style root-and-template morphology, with roots that can be analyzed as consisting of consonants only, and the vowels coming from a separate morphological tier? I've heard that some Native American languages have similar systems, but I don't know which.
I realize that Germanic ablaut (for example) is a similar kind of phenomenon, but it's not basic to morphology in Germanic the way that it is in Semitic; I'm asking about languages where this is the basic strategy of verbal and/or nominal inflection.
