Pavane, I experimented with Font Creator Program (Shareware) to create a new set of fonts for Tin Whistle and Alto Sax tablature. Because of my inexperience it was fairly tedious to start from scratch - and I wasn't using exotic graphics software to create the .bmp's.

In essence though it is moderately easy to import an existing font style, modify glyphs in some way so that they're more legible and then resave the font style with a different title. (Iknow that it's not relevant for your purposes, but you can also make the font such that it's Mac compatible.

Drop me a line if you'd like me to have a quick experiment with a couple of glyphs.

Regards, John
