Re: [Bulk] Re: Adding an extra staff

[Vivian Barty-Taylor]

Hi Alistair, hi list,

I debugged this code in 2.10.33, but it should work in 2.11

I've never started Staff contexts "on the fly" - didn't even know it  
was possible, but as you see it leads to unforeseen problems. In  
Lilypond the brackets <<   >> mean "interpret these contexts  
simultaneously". That was one of the problems with your code - that  
by starting the Staff context within the other one, Lilypond got  
confused about how to do this (I suppose it has something to do with  
Context hierarchy, but I'm not a programmer, so don't ask me!)

Here is a debugged version of your code. You can enter any notes you  
want in the three variable definitions above - staffOne, staffTwo,  
staffThree . This is much cleaner than your code, where you had typed  
the notes directly into the context.

By the way, the brace at the beginning of the PianoStaff isn't  
printing - I think this has to do with you having a StaffGroup within  
a PianoStaff - you could try removing it (it isn't really necessary)  
and see if the brace prints then.

Hope this helps, and good luck using Lilypond.

All the best,
Vivian.
