Re: use of set Timing.measurePosition is disrupting automatic beaming

[Roderick Mackenzie]

Hallo,

many thanks for the suggestions.

I am using an older version because it happens to be in the Ubuntu LTS
repositories and I have not got round to upgrading yet.

Elaine, I use repeat barlines at the start of each part because
bagpipe tunes always have them at the start and end of each part, and
repeat volta only places them at the end.

David, you are quite correct: the partial measures at the end and
start of a part always add up to a full measure. The code you included
compiles correctly under my older version of Lilypond so that is very
hopeful. I will see what happens when I write out a complete tune like
that.

Best wishes,
Roddy
