Thanks, you are right, the biggest defined lm font is lmroman12. But that's 
beside the point. The typescripts are configured correctly. BTW, you get the 
same problem with Wolfgang's third/typescripts/type-optical.tex, which defines 
four optical sizes of the Adobe Pro fonts. Like Mojca, I don't know about the 
context magic innards and how to fix this either. Is there a way for 
interactive line tracing in luatex, similar to e.g. bash -x?
