I guessed that – but what can I do if I need the \augmentum ? Add spacer
rests to fill up the bar? Or is this all cured by removing the
Default_bar_line_engraver as you showed me below?

Thanks for your settings. I comment them inline:

(1) Whatever this Spacing spanner change does, it looks much better
(2) I tried to remove the bar line engraver but all I found was the
Bar_engraver which obviously did not have the desired effect.

Perhaps you can also have a look at my more detailed description, I will
send to Michael and David.

Thanks for your help,
