I'm just enquiring about the state of quartertone implementation as I am writing a report and require this feature if the example is to be authentic. Also, I am using mudela-book for the report and was wondering whether there is any easy solution to the \begin{verbatim} problem. Otherwise I am having no problems using it. I picked up the syntax etc. from the postscript document. Adam -- Adam Tee Postgraduate Research Student Dept of Electronic & Electrical Engineering and Dept of Music University of Leeds LS2 9JT UK
