\example{basename}{ext}
        {musicwidth}{separation}{codewidth}
        {musicvskip}{alignment}{codevskip}

Set music example together with M-Tx (or other) code.

basename   - musicfile is basename.tex
ext        - codefile is basename.ext
separation - distance between music and code minipages
alignment  - c, t or b (for code minipage)
