I call it music like the ELF. The subset of music which contains digital instruments, or which includes analog synths, is a very small subset of music, easy to differentiate by simply calling it "electronic music", or, to differentiate in greater detail by calling it by the specific subgenre or musicians name or bands name.
Then you run into a grey area, because what about DJs like King Tubby? They took raggae music and remixed it with effects, but, technically there may not be any synths or digital elements. Yet Dub is more or less universally acclaimed and accepted as the 1st generation of electronica.
