Re: Concatenating LilyPond scores with different staff sizes.

[Valentin Petzel]

Hello everyone,

the problem seems to be that while layout-set-staff-size does set the relevant 
sizes it does not change the base unit everything is relative to (and which is 
relative to the global staff size).

So one solutions could be to do something to allow scaling of the base unit on 
layout level.

Cheers,
Valentin
