Re: [Denemo-devel] \partial Upbeat not shown in Denemo

[Nils Gey]

Ah, thanks. Now I understand. I have to add a uncomplete measure manually which 
is incomplete then. That makes sense. I thougt I just could add one note after 
another and Denemo would care about barlines. Actually Lilypond TOOK care about 
the barlines but not Denemo. Maybe a function to rearrange all the barlines? 
Luckiely my piece is only a small one: I had to go to all the measures manually 
and cut/paste the notes around the barlines. If it were bigger this would have 
been a pain.

Thanks for your hard work, Richard.
