This baffles me, but as someone who hasn't used Windows much in the
last few years, I have no idea how to help you with this bit.

The myStaffSize variable is needed for determining font size
relationships and should be set to whatever your global staff size is
(default is 20). The ( / myStaffSize 20) divides myStaffSize by twenty
so that the text sizes are scaled properly with the staff size.
