If looked up the ABC tutorials and may have gone snowblind before I found it, but could you please explain the lowercase "z"? Or if you're feeling generous, the whole thing? I just don't seem to be processing what I'm reading on the various sites. I've been reaing notes, and tabs for long and long, and maybe I'm just stuck in a Geezer-Mind-Rust zone on this. Any help would be much appreciated. Thanks, CharleyD2
