I'd like to use FiraSans
as default for my documents. The default values work fine, but I'd like FiraSans Medium as my default bold font and FiraSans Light as my default regular font.
I already tried \renewcommand{\seriesdefault}{l}
and
\renewcommand{\bfdefault}{mb}
but it has no effect (this worked while I used OpenSans - but with FiraSans only the regular font is affected, but the bold font stays untouched).
The several font series can be looked up here: ftp://ftp.rrzn.uni-hannover.de/pub/mirror/tex-archive/fonts/fira/latex/FiraSans.sty
Further, I have a problem with sfmath
as it uses FiraSans Regular even when I use \renewcommand{\seriesdefault}{l}
for FiraSans Light. I'd like to have the math font in light weight, too. Is that possible?
