Hi, if I need an additional pair of upright and italic font faces, e.g. a Medium or Light version, would it make sense to define them like this: % adapted from font-pre.mkxl \definefontalternative[md] \definefontalternative[mi] \definefontalternative[ms] \definealternativestyle [medium] [\md] [] \definealternativestyle [mediumitalic,italicmedium] [\mi] [] \definealternativestyle [mediumslanted,slantedmedium][\ms] [] \definealternativestyle [sansmedium] [\ss\md] [] \definealternativestyle [serifmedium] [\rm\md] [] \definealternativestyle [monomedium] [\tt\md] [] %\definealternativestyle [mediumface] [\mediumface] [] \unexpanded\def\normalmd{\let\fontalternative\md\font_helpers_synchronize_font} \unexpanded\def\normalmi{\let\fontalternative\mi\font_helpers_synchronize_font} \unexpanded\def\normalms{\let\fontalternative\ms\font_helpers_synchronize_font} \let\md\normalmd \let\mi\normalmi \let\ms\normalms \definehighlight[medium ] [command=no,style=medium] \definehighlight[mediumitalic ] [command=no,style=mediumitalic] \definehighlight[mediumslanted] [command=no,style=mediumslanted] Is that necessary? And is it enough? \starttypescript [sans] [alegreya] \definefontsynonym[AlegreyaSans-Regular][name:AlegreyaSans-Regular] \definefontsynonym[AlegreyaSans-Italic][name:AlegreyaSans-Italic] \definefontsynonym[AlegreyaSans-Caps][name:AlegreyaSansSC-Regular] \definefontsynonym[AlegreyaSans-ItalicCaps][name:AlegreyaSansSC-Italic] \definefontsynonym[AlegreyaSans-Medium][name:AlegreyaSans-Medium] \definefontsynonym[AlegreyaSans-MediumItalic][name:AlegreyaSans-MediumItalic] \definefontsynonym[AlegreyaSans-MediumCaps][name:AlegreyaSansSC-Medium] \definefontsynonym[AlegreyaSans-MediumItalicCaps][name:AlegreyaSansSC-MediumItalic] \definefontsynonym[AlegreyaSans-Bold][name:AlegreyaSans-Bold] \definefontsynonym[AlegreyaSans-BoldItalic][name:AlegreyaSans-BoldItalic] \definefontsynonym[AlegreyaSans-BoldCaps][name:AlegreyaSansSC-Bold] \definefontsynonym[AlegreyaSans-BoldItalicCaps][name:AlegreyaSansSC-BoldItalic] \stoptypescript \starttypescript [sans] [alegreya] [name] \definefontsynonym [Sans] [AlegreyaSans-Regular] [] \definefontsynonym [SansItalic] [AlegreyaSans-Italic] [] \definefontsynonym [SansSlanted] [AlegreyaSans-Italic] [] \definefontsynonym [SansMedium] [AlegreyaSans-Medium] [] \definefontsynonym [SansMediumItalic] [AlegreyaSans-MediumItalic][] \definefontsynonym [SansMediumSlanted][AlegreyaSans-MediumItalic][] \definefontsynonym [SansBold] [AlegreyaSans-Bold] [] \definefontsynonym [SansBoldItalic] [AlegreyaSans-BoldItalic] [] \definefontsynonym [SansBoldSlanted][AlegreyaSans-BoldItalic] [] \definefontsynonym [SansCaps] [AlegreyaSans-Caps] \stoptypescript
