free: DTL FontMaster Light 2.7.0
The Light editions of DTL Bezier- and IkarusMaster basically only have one major restriction: not more than 256 glyphs can be stored per editable glyph database. Changes in larger glyph databases, like for instance in the included FM Demo Font, can’t be saved. With the glyph editors it is possible to generate PostScript Type1 fonts for Windows though, and the DTL TraceMaster module is fully functional.
